This patent application is based on and claims priority pursuant to 35 U.S.C. § 119(a) to Japanese Patent Application No. 2022-046051, filed on Mar. 22, 2022, Japanese Patent Application No. 2022-046050, filed on Mar. 22, 2022, and Japanese Patent Application No. 2022-046052, filed on Mar. 22, 2022, in the Japan Patent Office, the entire disclosure of which is hereby incorporated by reference herein.
The present disclosure relates to a communication terminal, a communication management system, a remotely-operable mobile apparatus, a communication system, a remote operation method, a communication management method, a control method, a communication method, a processing method, and a recording medium.
Communication systems are becoming widespread. In the communication systems, communication terminals communicate with each other via a communication network such as the Internet or a local area network (LAN) across a plurality of sites to transmit and receive video and/or audio to and from each other. Such a communication system allows remote users to communicate with each other to have a teleconference, for example.
Also known is a telepresence robot (hereinafter referred to as a “robot”) that combines teleconferencing and robotics with remote control technology. Telepresence is technology that combines remote control and robotic technology and allows a user to remotely operate a robot to make the robot behave in such a manner that the user can feel as if the user were present at a certain place through the robot.
The robot is typically equipped with a display. The robot includes a teleconferencing device using the display, and has an ability to move by remote operation. While the user is on a teleconference with a personal computer (PC), a smartphone, or a tablet terminal, the user remotely controls the robot, which is located at a place other than the user's true location such as a counterpart site, to make their own decision as to whom to communicate with and where to visit. Unlike the existing teleconferencing technology, the telepresence technology enables the robot to play a role as an avatar of the user to move to a location other than the user's true location or hold a conversation with a remote person. As a result, the remote person can feel the presence of the user in an unprecedented way.
Some facilities, such as museums and art museums, show things valuable to specific fields, scientific materials, works of art, and so on to visitors in the form of an exhibition. With the recent decline in the number of visitors due to the movement restrictions brought about by COVID-19, services such as online experience tours have started to be provided. There is a movement to introduce such services into company showrooms.
Such a service launches a demonstration experiment for introducing a remote tour utilizing a robot to allow remote users to freely tour the facility online. The remote tour presents a video captured by the robot to a plurality of remote users to provide a simulated experience in which the remote users can tour the facility. The remote tour also enables each user to remotely operate the robot to tour the facility freely.
However, the example described above is based on the assumption that one user occupies and controls a remotely-operable mobile apparatus such as the robot. In remote tours or other services in which a plurality of users are viewing a video captured by a remotely-operable mobile apparatus, accordingly, it is desirable to appropriately manage control of remote operations to be performed on the remotely-operable mobile apparatus.
A communication terminal for remotely operating a mobile apparatus, includes circuitry that receives a remote operation to be performed on an operation target of the mobile apparatus, and transmits operation information indicating the remote operation to be performed on the operation target to remotely operate the operation target, the operation target being a target to which an operation right that is exclusive is to be applied.
A more complete appreciation of embodiments of the present disclosure and many of the attendant advantages and features thereof can be readily obtained and understood from the following detailed description with reference to the accompanying drawings, wherein:
The accompanying drawings are intended to depict embodiments of the present disclosure and should not be interpreted to limit the scope thereof. The accompanying drawings are not to be considered as drawn to scale unless explicitly noted. Also, identical or similar reference numerals designate identical or similar components throughout the several views.

However, the disclosure of this specification is not intended to be limited to the specific terminology so selected and it is to be understood that each specific element includes all technical equivalents that have a similar function, operate in a similar manner, and achieve a similar result.
Referring now to the drawings, embodiments of the present disclosure are described below. As used herein, the singular forms “a.” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise.
An overview of a communication system 1 will be described with reference to
The robot R mainly includes a wide-angle image capturing device 9, a communication terminal 10X, and a moving device 20 that moves the robot R. The robot R is an example of a remotely-operable mobile apparatus. The remotely-operable mobile apparatus is an apparatus that moves on the ground, in the air, in space, on water, in water, or underground by remote operation. The remotely-operable mobile apparatus includes an autonomous mobile apparatus. The remotely-operable mobile apparatus includes a remotely-operable traveling apparatus with traveling performance. The autonomous mobile apparatus includes an autonomous traveling apparatus with traveling performance. The robot R is a type of remotely-operable traveling apparatus or autonomous traveling apparatus. The robot R is provided with an environmental sensor such as a temperature sensor, a humidity sensor, an oxygen sensor, or a carbon dioxide sensor, and an illumination device or the like that illuminates the periphery of the robot R.
For example, the robot R is placed in a company 801, and an operator 810 is located at home 802. The operator 810 is, for example, a user (user a). In the robot R, the communication terminal 10X and the wide-angle image capturing device 9 are mounted on the moving device 20. In
In the situation illustrated in
As a non-limiting example, as illustrated in
The wide-angle image capturing device 9 transmits a spherical video (an example of a second video) described below to the communication terminal 10X. The communication terminals 10A, 10B, and 10C each include a narrow-angle image capturing unit 14 described below and a microphone, and transmit and receive video and audio to and from one another. The communication terminal 10X transmits the spherical video and at least one of a front video 831 and a back video 832 to the communication terminals 10A, 10B, and 10C. The communication terminals 10A, 10B, and 10C transmit front videos 831 of the users a, b, and c to the communication terminal 10X.
In the communication terminals 10A, 10B, and 10C, application programs (hereinafter referred to as “apps”) for accepting an operation related to movement of the moving device 20 operate. The users a, b, and c input operation instructions while checking the video transmitted from the communication terminal 10X. Operation information indicating a remote operation (operation instruction) input by the operator 810 is transmitted from the communication terminal 10A to the communication terminal 10X via a communication network 2.
The communication terminal 10X and the moving device 20 can communicate with each other via short-range wireless communication such as Bluetooth®. The communication terminal 10X controls the moving device 20 in accordance with an operation instruction given by a specific user having an operation right. In an example, the specific user (located at the home 802) remotely controls the moving device 20 to move.
The operation right is a right (operation right that is exclusive) granted to a specific user (including a specific communication terminal) among a plurality of users (including communication terminals) such that the specific user can exclusively perform a remote operation on each operation target (such as the narrow-angle image capturing unit 14 and the moving device 20) of the robot R. A different operation right is set for each operation target. The operation right may also be referred to as a special right that allows a specific user to perform a remote operation. In other words, a user who does not have the operation rights is unable to perform remote operations on the respective operation targets of the robot R. Examples of the user include people and organizations such as departments and companies.
If the narrow-angle image capturing unit 14 incorporated in the communication terminal 10X is capable of capturing only a scene in front of or behind the moving device 20, it is difficult for the user to check the situation around the moving device 20 (e.g., the situation under or to the left or right of the moving device 20). Thus, the wide-angle image capturing device 9 capable of capturing an image of 360 degrees around the moving device 20 is mounted on the communication terminal 10X. The wide-angle image capturing device 9 may be mounted on the communication terminal 10X or may be mounted on the moving device 20. The wide-angle image capturing device 9, which is capable of capturing an image of a wide-angle range, is disposed in an upper part of the robot R, for example, to capture surroundings without being blocked by obstacles. In
An example of the display of a spherical video in which objects in 360 degrees around the wide-angle image capturing device 9 appears will be described with reference to
Since the moving device 20 has the same orientation as the robot R, the moving device 20 and the robot R may be regarded as the same in terms of orientation. The orientation of the moving device 20 is the direction in which the moving device 20 is facing. In an example, the orientation of the moving device 20 is a front direction or a forward movement direction. The orientation of the moving device 20 may be lateral, upward, downward, or the like as long as the user can grasp the direction in which the moving device 20 is facing.
The user causes the communication terminal 10A to display a predetermined-area video. The video displayed on the spherical video display screen 1010 is a predetermined-area video. In
As described above, the direction of viewing by the user does not necessarily match the front direction of the moving device 20. The communication terminal 10A rotates the robot R based on a difference between the front direction of the moving device 20 and an imaging direction defining the predetermined-area video, and displays the rotated robot R in the spherical video. The imaging direction is a direction pointing to the center of the predetermined-area video. The displayed image 840 of the robot R is not an image of the robot R in real space, but is an image created by computer graphics (CG). The CG is an image rendered by a computer. While two-dimensional CGs and three-dimensional CGs are mainly available, three-dimensional CGs are used in this embodiment.
It is possible to understand in which direction the robot R (the moving device 20) is facing in the spherical video. In the example illustrated in
In
Next, pattern 2 will be described.
As illustrated in
As described above, the user can grasp the direction in which the spherical video is viewed from the robot R. The user can also grasp the direction in which the robot R is facing. The example illustrated in
In the pattern 3, the operation button 860 is displayed when the imaging direction and the front direction of the robot R substantially match. Thus, if the operation button 860 is displayed as a result of the user's action of changing the predetermined-area video, the user can determine that the imaging direction and the front direction of the robot R substantially match. Accordingly, the imaging direction and the direction of viewing in the spherical video by the user can be made to match each other. Since the operation button 860 is displayed when the imaging direction and the direction of viewing in the spherical video by the user match, the user can grasp where the robot R will move if the robot R moves forward.
The communication terminal 10 is communicably connected to the other communication terminals 10 via the communication network 2. The relay device 30 is communicably connected to other relay devices via the communication network 2, and the communication management system 50 is communicably connected to other communication management systems via the communication network 2. The communication network 2 may include, for example, a LAN, the Internet, a mobile phone network, or a dedicated line.
The communication terminal 10 is, for example, a general-purpose information processing apparatus such as a tablet terminal, a smartphone, or a PC, or a dedicated communication terminal such as a teleconferencing apparatus. In an example, the communication terminal 10 transmits and receives video and/or audio to and from one or more of the other communication terminals 10 to perform a teleconference. The teleconference is an example of a video conversation. The video conversation includes, but is not limited to, conferencing. The video conversation is an example of video distribution. The video distribution includes, but is not limited to, a voice conversation.
The communication terminal 10α executes an application corresponding to the communication system 1 to have a teleconference with the communication terminal 10X and remotely operate the moving device 20 via the communication terminal 10X. In an example, in response to operation of the operation button 860 displayed on a display screen for the teleconference, the communication terminal 10α moves the moving device 20 including the communication terminal 10X forward, backward, leftward, of rightward, for example. The communication terminal 10α may activate browser software, and the browser software may display a video and accept an operation of the moving device 20 on the browser software.
In the example illustrated in
The moving device 20 of the robot R is a device having a traveling function. For example, the moving device 20 has a plurality of wheels that are driven to perform movement such as forward movement, backward movement, right turn, or left turn in accordance with control from the communication terminal 10X attached to the moving device 20. When the user gives an instruction to move the moving device 20 to the left or right by remote operation, the moving device 20 moves forward after turning to the right or left. The external appearance of the moving device 20 illustrated in
The relay device 30 is, for example, an information processing apparatus or a system including one or more information processing apparatuses. The relay device 30 relays content data (including video and audio) transmitted and received between the plurality of communication terminals 10. The audio includes voice, noise, and the like. The plurality of communication terminals 10 may directly transmit and receive content data to and from each other without the intervention of the relay device 30.
The communication management system 50 is, for example, an information processing apparatus or a system including one or more information processing apparatuses. The communication management system 50 performs operations, for example, login authentication from the communication terminal 10, management of the communication state of the communication terminal 10, management of a counterpart list and the like, and control of a session for communication between the plurality of communication terminals 10 via the relay device 30.
In one embodiment, a session is implemented by the relay device 30 relaying content data including video and/or audio between the plurality of communication terminals 10.
In the configuration described above, for example, the user a of the communication terminal 10A communicates with the communication terminal 10X to move the communication terminal 10X and the moving device 20 by remote operation. As a result, in an example, the user a of the communication terminal 10A moves the communication terminal 10X and the moving device 20 to a location close to any party and have a teleconference with the party.

As illustrated in
The imaging unit 301 includes wide-angle lenses (so-called fish-eye lenses) 302a and 302b each having an angle of view of 180 degrees or more to form a hemispherical image. The imaging unit 301 further includes two imaging elements 303a and 303b corresponding to the wide-angle lenses 302a and 302b, respectively. Each of the imaging elements 303a and 303b includes an image sensor such as a complementary metal oxide semiconductor (CMOS) sensor or a charge-coupled device (CCD) sensor, a timing generation circuit, and a group of registers. The image sensor converts an optical image formed by the fish-eye lens 302a or 302b into an electric signal and outputs image data. The timing generation circuit generates horizontal or vertical synchronization signals, pixel clocks, and the like for the image sensor. In the group of registers, various commands, parameters, and the like for an operation of the imaging element 303a or 303b are set.
Each of the imaging elements 303a and 303b of the imaging unit 301 is connected to the image processor 304 via a parallel/F bus. Each of the imaging elements 303a and 303b of the imaging unit 301 is also connected to the imaging controller 305 through a serial I/F bus such as an inter-integrated circuit (I2C) bus. The image processor 304, the imaging controller 305, and the audio processor 309 are connected to the CPU 311 via a bus 310. The ROM 312, the SRAM 313, the DRAM 314, the operation unit 315, the network I/F 316, the communication unit 317, and the electronic compass 318, and so on are also connected to the bus 310.
The image processor 304 acquires respective items of image data from the imaging elements 303a and 303b via the parallel I/F buses and performs predetermined processing on the items of image data. Thereafter, the image processor 304 combines the items of image data to generate data of an equirectangular projection image as illustrated in
The imaging controller 305 usually functions as a master device while each of the imaging elements 303a and 303b usually functions as a slave device. The imaging controller 305 sets commands and the like in the group of registers of each of the imaging elements 303a and 303b via the I2C bus. The imaging controller 305 receives various commands from the CPU 311. The imaging controller 305 further acquires status data and the like of the group of registers of each of the imaging elements 303a and 303b via the I2C bus. The imaging controller 305 sends the obtained status data and the like to the CPU 311.
The imaging controller 305 instructs the imaging elements 303a and 303b to output the image data at the time when a shutter button of the operation unit 315 is pressed. In one example, the ide-angle image capturing device 9 has a function of displaying a preview image on a display (e.g., the display of the communication terminal 10X) or a function of displaying a moving image. In the case of displaying a moving image, image data are continuously output from the imaging elements 303a and 303b at a predetermined frame rate (frames per minute).
The imaging controller 305 operates in cooperation with the CPU 311 to synchronize the time when the imaging element 303a outputs image data and the time when the imaging element 303b outputs the image data. In this embodiment, the wide-angle image capturing device 9 does not include a display. In an example, the wide-angle image capturing device 9 may include a display.
The microphone 308 converts a recorded sound into audio data. The audio processor 309 acquires the audio data output from the microphone 308 via an I/F bus and performs predetermined processing on the audio data.
The CPU 311 controls the overall operation of the wide-angle image capturing device 9 and performs processing. The ROM 312 stores various programs to be executed by the CPU 311. Each of the SRAM 313 and the DRAM 314 operates as a work memory to store programs to be executed by the CPU 311 or data being currently processed. More specifically, in one example, the DRAM 314 stores image data currently processed by the image processor 304 and data of the equirectangular projection image on which processing has been performed.
The operation unit 315 collectively refers to various operation buttons such as a shutter button. The operator operates the operation unit 315 to input various image capturing modes or image capturing conditions.
The network I/F 316 collectively refers to an interface circuit such as a USB I/F for interfacing with an external medium such as a Secure Digital (SD) card or a PC. The network I/F 316 may be either wired or wireless. The data of the equirectangular projection image, which is stored in the DRAM 314, is stored in the external medium via the network I/F 316 or transmitted to an external terminal (apparatus), such as the communication terminal 10X, via the network/F 316, as desired.
The communication unit 317 communicates with the external terminal (apparatus) such as the communication terminal 10X via the antenna 317a of the wide-angle image capturing device 9 by short-range wireless communication such as Wireless Fidelity (Wi-Fi), near field communication (NFC), or Bluetooth®. The communication unit 317 can also transmit the data of the equirectangular projection image to the external terminal (apparatus) such as the communication terminal 10X.
The electronic compass 318 calculates an orientation of the wide-angle image capturing device 9 from the Earth's magnetism and outputs orientation information. The orientation information is an example of related information (metadata) in compliance with exchangeable image file format (Exif). The orientation information is used for image processing such as image correction of a captured image. The related information also includes data of a date and time when the image was captured, and data of a data size of image data.
The gyro sensor 319 detects a change in tilt (roll, pitch, and yaw) of the wide-angle image capturing device 9 with movement of the wide-angle image capturing device 9. The change in tilt is one example of related information (metadata) in compliance with Exif. This information is used for image processing such as image correction of a captured image.
The acceleration sensor 320 detects acceleration in three axial directions. The detected acceleration is used to detect the position of the wide-angle image capturing device 9 (e.g., the tilt of the wide-angle image capturing device 9 relative to the direction of gravity). The gyro sensor 319 and the acceleration sensor 320 improve the accuracy of image correction.
Next, a situation in which the wide-angle image capturing device 9 is used will be described with reference to
Next, an overview of a process for generating an equirectangular projection image EC and a spherical image CE from the images captured by the wide-angle image capturing device 9 will be described with reference to
As illustrated in
Open Graphics Library for Embedded Systems (OpenGL ES) is used to map the equirectangular projection image EC such that the equirectangular projection image EC covers a surface of a sphere, as illustrated in
Since the spherical image CE is an image mapped so as to cover the surface of the sphere, part of the image may look distorted when viewed by a user, providing a strange feeling. To overcome the strange feeling, an image of a predetermined area, which is part of the spherical image CE, is displayed as a flat image with less distortion to make the user feel comfortable when viewing the image. The image of the predetermined area corresponds to the predetermined-area video described above. The predetermined-area video will be described with reference to
The predetermined-area video Q illustrated in
As illustrated in

The communication terminal 10α includes a transmitting/receiving unit 11, an operation input acceptance unit 12, a communication control unit 13, a narrow-angle image capturing unit 14, a voice input unit 15a, a voice output unit 15b, a display control unit 16, and a storing and reading unit 17. Each of these units is a function or means that is implemented by any one of the hardware elements illustrated in

The transmitting/receiving unit 11 transmits and receives various data (or information) to and from another communication terminal, device, or system via the communication network 2. Before starting a voice conversation with a desired counterpart terminal, the transmitting/receiving unit 11 starts receiving, from the communication management system 50, state information indicating the states of communication terminals serving as candidate conversation counterparts. The state information indicates the operating state of each communication terminal 10 (whether the communication terminal 10 is online or offline). If the communication terminal 10 is online, the state information further indicates a detailed state such as information indicating whether the communication terminal 10 is allowed to make a voice conversation, and information indicating whether the communication terminal 10 is making a voice conversation.
The operation input acceptance unit 12 accepts various inputs to the communication terminal 10 by the operator. For example, in response to the operator performing an operation of turning on the power of the communication terminal 10, the operation input acceptance unit 12 accepts the operation and performs control to turn on the power.
For example, in response to receipt of the operation of turning on the power, the communication control unit 13 automatically transmits, from the transmitting/receiving unit 11, login request information indicating a request for login, and the current Internet protocol (IP) address of the request sender terminal to the communication management system 50 via the communication network 2. In response to the operator instructing to turn off the power of the communication terminal 10, the transmitting/receiving unit 11 transmits, to the communication management system 50, state information indicating turning off of the power of the communication terminal 10. After that, the operation input acceptance unit 12 turns off the power of the communication terminal 10. This enables the communication management system 50 to grasp that the power of the communication terminal 10 has been switched from on to off. Further, the communication control unit 13 performs various communication controls via the relay device 30. The communication controls include establishment of a session for transmitting and receiving content data to and from another communication terminal 10, and disconnection of a session for transmitting and receiving content data to and from another communication terminal 10. The communication control unit 13 according to this embodiment transmits control information of a session (e.g., start request information and start response information described below) to the communication management system 50. The control information to be transmitted to the communication management system 50 includes a communication identification (ID) of the communication terminal 10.
The communication ID is an example of identification information of an account with which the operator can participate in a session for transmitting and receiving content data using the communication terminal 10. The communication ID may be, for example, a user ID, which is identification information of the operator, an application ID, which is identification information of an application, or a contract ID, which is identification information of a contractor of the communication terminal 10. Examples of the communication ID include information obtained by combining at least two of a character, a number, a sign, and various types of symbols. In an example, the communication ID is an email address.
The narrow-angle image capturing unit 14 has a function similar to that of a camera mounted on a typical digital camera, smartphone, tablet terminal, notebook PC, or the like, and has a viewing angle up to 180 degrees. The narrow-angle image capturing unit 14 is different in viewing angle from the wide-angle image capturing device 9 having a viewing angle of 360 degrees. The narrow-angle image capturing unit 14 converts imaging data obtained by capturing an image of an object or the like into predetermined image (video) data and outputs the image (video) data. The narrow-angle image capturing unit 14 is disposed on each of the front and back sides of the communication terminal 10 such that the narrow-angle image capturing unit 14 on the front side of the communication terminal 10 captures a front video and the narrow-angle image capturing unit 14 on the back side of the communication terminal 10 captures a back video. The communication terminal 10 may include more image capturing units.
The voice input unit 15a converts the voice of the operator into an audio signal using the microphone 114, converts the audio signal into predetermined audio data, and outputs the audio data. The voice output unit 15b converts the audio data into an audio signal, outputs the audio signal to the speaker 115, and outputs a voice from the speaker 115.
For example, the display control unit 16 causes the display unit 109, the display input unit 110, or the like to display image data included in content data received by the communication terminal 10. Further, the display control unit 16 can transmit information on a counterpart list received from the communication management system 50 to the display unit 109 and cause the display unit 10) to display the counterpart list.
The storing and reading unit 17 performs a process for storing various data in the storage unit 1000 and reading various data stored in the storage unit 1000.
The storage unit 1000 stores, for example, the communication ID described above and authentication information such as a password corresponding to the communication ID. The storage unit 1000 stores image data and audio data, which are received during a voice conversation with the counterpart terminal, in such a manner that the image data and the audio data are overwritten each time image data and audio data are received. An image is displayed on the display unit 109 or the like in accordance with the image data before being overwritten, and a voice is output from the speaker 115 in accordance with the audio data before being overwritten.
Next, the functional components of the communication terminal 10X will be described.
The spherical video receiving unit 19b receives an equirectangular projection video from the wide-angle image capturing device 9 via wireless communication such as Bluetooth® or wired communication such as a USB cable. The equirectangular projection video is a moving image repeatedly transmitted with a frequency such that the equirectangular projection video can be regarded as a moving image. In an example, the equirectangular projection video may be a still image. In another example, the equirectangular projection video may be switched between a moving image and a still image.
The operation instruction receiving unit 19a receives operation information from the communication terminal 10A via the transmitting/receiving unit 11. The operation information is information for requesting the communication terminal 10X to control the device (the moving device 20). The operation information includes, for example, a communication ID of the communication terminal 10 from which the operation information is transmitted, an operation instruction indicating the content of the control to be requested, and the like.
The device control unit 19c controls the moving device 20 in accordance with the content of an operation included in the operation information received by the operation instruction receiving unit 19a. The operation information is information indicating an instruction for remotely operating each function of the robot R from the communication terminal 10α. Examples of the content of an operation included in the operation information include an operation of driving the moving device 20 of the robot R to rotationally move the robot R to the right, and an operation of causing the wide-angle image capturing device 9 to capture an image.
The inter-device communication unit 19d communicates with the moving device 20 and the wide-angle image capturing device 9 using the short-range wireless communication unit 118.
When the communication terminal 10X receives the operation information transmitted from the communication terminal 10α, the operation right checking unit 18 checks whether the communication terminal 10α (or user) from which the operation information is transmitted has the operation right for an operation target indicated by the operation information.
The storage unit 1000 stores an operation right management database (DB) 1006. The operation right information managed by the operation right management DB 1006 has the same content as the information managed in an operation right management DB 5006 of the communication management system 50. Each time the communication management system 50 updates the operation right information, the operation right information is transmitted to the communication terminal 10X. The operation right information will be described in detail below. In an example, the communication terminal 10X does not include the operation right checking unit 18. In this case, the communication terminal 10X does not include the operation right management DB 1006.
The moving device 20 includes, for example, an inter-device communication unit 21 and a travel control unit 22. The inter-device communication unit 21 is implemented by, for example, the external device I/F 404 or the short-range wireless communication unit 405, which operate in accordance with instructions from the CPU 401 illustrated in
The travel control unit 22 controls, for example, the wheel driving unit 406 and the steering unit 407 illustrated in
The wide-angle image capturing device 9 includes, for example, a wide-angle image transmission unit 31, a wide-angle image capturing unit 32, and a point-of-view information management unit 33. The wide-angle image capturing unit 32 captures a wide-angle equirectangular projection video of 360 degrees around the wide-angle image capturing device 9 at a predetermined frame rate. The wide-angle image capturing unit 32 may capture a still image. The wide-angle image transmission unit 31 is implemented by the communication unit 317 illustrated in
The point-of-view information management unit 33 manages point-of-view information related to the point of view of the virtual camera IC illustrated in
The communication management system 50 includes a transmitting/receiving unit 51, a terminal authentication unit 52, a terminal management unit 53, a terminal extraction unit 54, a session management unit 55, a storing and reading unit 57, an operation right checking unit 58, and an operation right information creation unit 60. Each of these units is a function or means that is implemented by any one of the hardware elements illustrated in
The storage unit 5000 of the communication management system 50 stores an authentication management DB 5002. The authentication management DB 5002 includes an authentication management table 602 illustrated in Table 1. The authentication management table 602 manages a communication ID of the communication terminal 10, which is managed by the communication management system 50, and a password corresponding to the communication ID in association with each other. For example, the authentication management table 602 illustrated in Table 1 indicates that the password of the communication terminal 10 having the communication ID “01aa” is “aaaa”.
The storage unit 5000 of the communication management system 50 further stores a terminal management DB 5003. The terminal management DB 5003 includes a terminal management table 603 illustrated in Table 2. The terminal management table 603 manages, for the communication ID of each communication terminal 10, a counterpart name indicating the name of a counterpart, which is each communication terminal 10, the operating state of the communication terminal 10, a reception date and time when login request information described below was received by the communication management system 50, and the IP address of the communication terminal 10 in association with each other. For example, the terminal management table 603 illustrated in Table 2 indicates that the communication terminal 10 having the communication ID “01aa” has the terminal name “Head Office in Japan” and the operating state “Online (communicable)”. The terminal management table 603 also indicates that the communication terminal 10 having the communication ID “01aa” has the date and time of reception of login request information by the communication management system 50 “13:40 on Apr. 10, 20xx” and the IP address “1.2.1.3”. Counterpart List Management DB
The storage unit 5000 of the communication management system 50 further stores a counterpart list management DB 5004. The counterpart list management DB 5004 includes a counterpart list management table 701 as illustrated in Table 3. The counterpart list management table 701 manages the communication ID of a request sender terminal from which a request for starting communication in a teleconference is transmitted, in association with the communication IDs of counterpart terminals registered as candidate counterpart terminals. The communication ID of a request sender terminal may also be referred to as the “request-sender-terminal communication ID”. The communication ID of a counterpart terminal may also be referred to as the “counterpart-terminal communication ID”. For example, in the counterpart list management table 701 illustrated in Table 3, the candidate counterpart terminals that the request sender terminal having the communication ID “01aa” can request to start communication are the communication terminals having the communication IDs “01b1”, “01b2”, and “01b3”. The candidate counterpart terminals are updated upon addition or deletion by the communication management system 50 in response to a request for addition or deletion being given from any request sender terminal to the communication management system 50.
This configuration allows the request sender terminal (e.g., the terminal with the communication ID “01aa”) to start communication with only a candidate counterpart terminal (e.g., the communication terminal with the communication ID “01b1”) registered in advance. The counterpart terminal (for example, the communication terminal with the communication ID “01b1”) is also not allowed to communicate with the request sender terminal (for example, the terminal with the communication ID “01aa”) unless the request sender terminal is registered in the counterpart list management table 701 as a counterpart terminal. The mechanism described above is preferable in that unintended communication terminals 10 are less likely to communicate with each other. In an example, any communication terminals 10 communicate with each other without being registered in the counterpart list management table 701.
The storage unit 5000 of the communication management system 50 further stores a session management DB 5005. The session management DB 5005 includes a session management table 702 illustrated in Table 4. The session management table 702 manages, for each session ID, which is identification information of a session, information such as a relay device ID of a relay device 30 used for relaying, a communication ID of a request sender terminal, a communication ID of a counterpart terminal, and a session participation date and time. For example, the session management table 702 illustrated in Table 4 indicates that the session having the session ID “se2” is performed between the request sender terminal with the communication ID “01ad” and the counterpart terminal with the communication ID “01ca”. The session management table 702 also indicates that the session having the session ID “se2” was started at 13:11:11 on Apr. 10, 20xx (“20xx/4/10 13:11:11”) via the relay device 30 having the relay device ID “111b”.
The storage unit 5000 of the communication management system 50 further stores the operation right management DB 5006. The operation right management DB 5006 includes an operation right management table 703 illustrated in table 5A. The operation right management table 703 manages, for each operation-right application target (user's operation target) ID, the name of the operation-right application target (i.e., the operation target), a communication ID of an operation-right-set terminal (or operation-right-set user), and information indicating the elapsed time of application of the operation right, in association with each other. The operation-right application target is the target to which the operation right is to be applied. The operation-right-set terminal is the terminal to which the operation right is set. The operation-right-set user is the user to whom the operation right is set.
The operation-right application target is also an object to be operated by the user and indicates each function of the robot R or each device of the robot R. In other words, the term “application target” may be used in terms of a right or privilege called an operation right, and the term “operation target” may be used in terms of an operation performed by the user.
The operation-right application target ID is an example of application-target identification information for identifying an operation-right application target. A user's operation target ID is an example of operation-target identification information for identifying an operation target to be remotely operated by the user.
The communication ID of an operation-right-set terminal (operation-right-set user) is identification information for identifying a specific communication terminal 10 or a specific user to which the operation right is set. The elapsed time of application of the operation right indicates the amount of time that elapses from the time point at which the operation right was set.
In the operation right management table 703 described above, no operation right may be set for a specific device or the like. For example, an operation right management table in which no operation right is set for the narrow-angle image capturing unit and the temperature sensor is illustrated in Table 5B.
Next, the functional configuration of the communication management system 50 will be described in detail. The transmitting/receiving unit 51 transmits and receives various data (or information) to and from another communication terminal, device, or system via the communication network 2.
The terminal authentication unit 52 determines whether the authentication management DB 5002 includes a combination of a communication ID and a password included in the login request information received via the transmitting/receiving unit 51 to authenticate the communication terminal 10.
The terminal management unit 53 stores and manages, for each communication ID, a counterpart name, an operating state, a reception date and time of request information and the like, and an IP address of a request sender terminal in the terminal management DB 5003 in association with each other. For example, in response to the user switching the power of the communication terminal 10 from on to off, the terminal management unit 53 changes the operating state of the terminal management DB 5003 from online to offline, based on state information transmitted from the communication terminal 10 and indicating turning off of the power.
The terminal extraction unit 54 searches the counterpart list management DB 5004 by using, as a search key, the communication ID of the request sender terminal from which the login request is transmitted, and extracts the communication ID of a counterpart terminal allowed to communicate with the request sender terminal. The terminal extraction unit 54 further searches the counterpart list management DB 5004 and also extracts the communication ID of another communication terminal for which the communication ID of the request sender terminal is registered as a candidate counterpart terminal.
Further, the terminal extraction unit 54 searches the terminal management DB 5003 described above by using the extracted communication ID of the candidate counterpart terminal as a search key, and reads the operating state for each extracted communication ID. As a result, the terminal management unit 53 can acquire the operating states of candidate counterpart terminals allowed to communicate with the request sender terminal from which the login request is transmitted. The terminal management unit 53 further searches the terminal management DB 5003 described above by using the communication ID of the request sender as a search key, and also acquires the operating state of the request sender terminal from which the login request is transmitted.
The session management unit 55 controls a session managed by the communication management system 50. The control of a session includes, for example, control for establishing a session, control for causing the communication terminal 10 to participate in the established session, control for disconnecting the session, and generation of a session ID. Further, the session management unit 55 stores and manages the communication ID of the communication terminal 10 from which a request for starting the session is transmitted, the communication ID of the counterpart terminal 10, and the like in the session management DB 5005 in association with the session ID serving as identification information of the session.
The storing and reading unit 57 is implemented by the HDD controller 505 operating in accordance with the instructions from the CPU 501 illustrated in
When the communication terminal 10X receives the operation information transmitted from the communication terminal 10α, the operation right checking unit 58 checks whether the communication terminal 10α (or user) from which the operation information is transmitted has the operation right for an operation target indicated by the operation information.
The operation right information creation unit 60 creates operation right information, based on the counterpart name managed in the terminal management DB 5003 and the information managed in the operation right management DB 5006, namely, the operation-right application target (operation target) ID, the operation-right application target (operation target), and the elapsed time of application of the operation right (see step S908 in
Next, the process flow of the communication system 1 will be described.
First, for example, the user a, who is the operator of the communication terminal 10A serving as a request sender terminal, performs an operation of turning on the power of the communication terminal 10A. In response to the operation performed by the user a, the operation input acceptance unit 12 accepts the operation of turning on the power and turns on the power of the communication terminal 10A (step S21).
Then, in response to the power being turned on, the communication control unit 13 transmits login request information from the transmitting/receiving unit 11 to the communication management system 50 via the communication network 2 to request a login (step S22). The login request information is transmitted in response to an operation of turning on the power of the communication terminal 10A, by way of example. In another example, the login request information may be transmitted in response to the user operating the input unit 108 or in response to activation of an application.
The login request information includes a communication ID (communication ID of the request sender terminal) for identifying the communication terminal 10A from which the login request information is transmitted, and a password. The communication ID and the password are, for example, information read from the storage unit 1000 via the storing and reading unit 17. When the login request information is transmitted from the communication terminal 10A to the communication management system 50, the communication management system 50, which is a receiver, can grasp the IP address of the communication terminal 10A, which is a transmitter.
Then, the terminal authentication unit 52 of the communication management system 50 searches the authentication management table 602 described above by using, as a search key, the communication ID and the password included in the login request information received via the transmitting/receiving unit 51. The terminal authentication unit 52 performs authentication in accordance with whether the combination of the communication ID and the password included in the login request information received from the communication terminal 10A matches a combination of a communication ID and a password included in the authentication management table 602 (step S23).
If the terminal authentication unit 52 determines that the login request is transmitted from the communication terminal 10A granted use privileges, the terminal management unit 53 changes the operating state corresponding to the communication ID “01aa” of the communication terminal 10A, which is recorded in the terminal management table 603, to “online (communicable)”. At this time, the terminal management unit 53 updates the reception date and time and updates the IP address of the communication terminal 10 as necessary (step S24). As a result, in the terminal management table 603, the operating state “online (communicable)”, the reception date and time “20xx.4.10.13:40”, and the IP address “1.2.1.3” of the communication terminal 10A are managed in association with the communication ID “01aa” of the communication terminal 10A.
Then, the transmitting/receiving unit 51 of the communication management system 50 transmits authentication result information indicating an authentication result obtained by the terminal authentication unit 52 described above to the communication terminal 10A from which the login request is transmitted, via the communication network 2 (step S25). In the following description, it is assumed that the terminal authentication unit 52 determines that the communication terminal 10A is a communication terminal granted use privileges.
The terminal extraction unit 54 of the communication management system 50 searches the counterpart list management table 701 by using, as a search key, the communication ID “01aa” of the request sender terminal (i.e., the communication terminal 10A) from which the login request is transmitted. As a result, the terminal management unit 53 extracts the communication ID of a candidate counterpart terminal allowed to communicate with the request sender terminal (i.e., the communication terminal 10A) (step S26). In one example, the communication IDs “01b1”, “01b2”, and “01b3” are extracted as the communication IDs of counterpart terminals associated with the communication ID “01aa” of the request sender terminal (i.e., the communication terminal 10A).
Then, the terminal extraction unit 54 searches the terminal management table 603 by using the extracted communication IDs (“01b1”, “01b2”, and “01b3”) of the candidate counterpart terminals as search keys. Accordingly, an operating state is read for each of the extracted communication IDs (“01b1”, “01b2”, and “01b3”) to acquire the operating states of the candidate destination terminals with the communication IDs (“01b1”. “01b2”, and “01b3”) (step S27).
Then, the transmitting/receiving unit 51 transmits counterpart state information to the request sender terminal (i.e., the communication terminal 10A) (step S28). The counterpart state information includes the operating states corresponding to the communication IDs (“01b1”, “01b2”, and “01b3”) of the candidate counterpart terminals. As a result, the request sender terminal (i.e., the communication terminal 10A) can grasp the current operating states of the candidate counterpart terminals with the communication IDs (“01b1”, “01b2”, and “01b3”), which may communicate with the request sender terminal (i.e., the communication terminal 10A). The communication terminal 10A displays a counterpart selection screen illustrated in
Further, the terminal extraction unit 54 of the communication management system 50 searches the counterpart list management table 701 by using, as a search key, the communication ID “01aa” of the request sender terminal (i.e., the communication terminal 10A) from which the login request is transmitted. As a result, the terminal extraction unit 54 extracts the communication ID of another request sender terminal for which the communication ID “01aa” of the request sender terminal (i.e., the communication terminal 10A) is registered as a candidate counterpart terminal (step S29). In the counterpart list management table 701 illustrated in Table 3, the communication IDs of the other request sender terminals to be extracted are “01b1”, “01b2”, and “01b3”.
Then, the terminal management unit 53 of the communication management system 50 searches the terminal management table 603 by using, as a search key, the communication ID “01aa” of the request sender terminal (i.e., the communication terminal 10A) from which the login request is transmitted. As a result, the terminal management unit 53 acquires the operating state of the request sender terminal (i.e., the communication terminal 10A) from which the login request is transmitted (step S30).
Then, the terminal management unit 53 of the communication management system 50 extracts the communication IDs (“01b1”. “01b2”, and “01b3”) for which the operating states are set to “Online (communicable)” in the terminal management table 603 from among the communication IDs (“01b1”. “01b2”, and “01b3”) extracted in step S29 described above.
Further, the transmitting/receiving unit 51 transmits counterpart state information to the communication terminal 10X corresponding to the extracted communication IDs (“01b1” “01b2”, and “01b3”). The counterpart state information includes the communication ID “01aa” of the request sender terminal (i.e., the communication terminal 10A), and the operating state “Online (communicable)”.
The other communication terminal, namely, the communication terminal 10X, also performs processing similar to the processing of steps S22 to S31 described above in accordance with, for example, an operation such as turning on the power. The power of the communication terminal 10X is turned on by, for example, the administrator of the moving device 20.
The operation input acceptance unit 12 of the communication terminal 10A accepts an operation of selecting the counterpart terminal (communication terminal 10X) by the user of the communication terminal 10A (step S901).
The transmitting/receiving unit 11 of the communication terminal 10A transmits, to the communication management system 50, start request information for requesting the start of a session (step S902). In an example, the start request information includes the request-sender-terminal communication ID, which is the communication ID of the communication terminal 10A serving as the request sender terminal, and the counterpart-terminal communication ID, which is the communication ID of the communication terminal 10X, which is the counterpart terminal. The start request information also includes information such as the IP address of the communication terminal 10A (the request sender IP address).
Upon receipt of the start request information from the communication terminal 10A, the terminal management unit 53 of the communication management system 50 updates the terminal management DB 5003, based on the communication ID “01 aa” of the request sender terminal (i.e., the communication terminal 10A) included in the start request information (step S903). For example, the terminal management unit 53 changes the information on the operating state corresponding to the communication ID “01aa” of the communication terminal 10A to “Online (communication in progress)” and also updates the information on the reception date and time.
The session management unit 55 of the communication management system 50 transmits, to the communication terminal 10X, which is the counterpart terminal, start request information for requesting the start of a session (step S904). In an example, the start request information includes the request-sender-terminal communication ID of the communication terminal 10A, which is the request sender terminal.
Upon receipt of the start request information from the communication management system 50, the communication terminal 10X transmits start response information to the communication management system 50 (step S905). In an example, the start response information includes the counterpart-terminal communication ID of the communication terminal 10X. In this embodiment, in an example, the start response information is transmitted without an operation on the communication terminal 10X. In another example, the start response information may be transmitted on the condition that the administrator operates the communication terminal 10X.
Upon receipt of the start response information from the communication terminal 10X, the terminal management unit 53 of the communication management system 50 updates the terminal management DB 5003, based on the communication ID “01b1” of the communication terminal 10X included in the start response information (step S906). For example, the terminal management unit 53 changes the information on the operating state corresponding to the communication ID “01b1” of the communication terminal 10X to “Online (communication in progress)” and updates the information on the reception date and time.
The session management unit 55 of the communication management system 50 assigns a number to a session ID, which is identification information for identifying the session (step S907). Further, the session management unit 55 stores the created session ID in the session management DB 5005 in association with the request-sender-terminal communication ID (i.e., the communication ID of the communication terminal 10A) and the counterpart-terminal communication ID (i.e., the communication ID of the communication terminal 10X) (step S907).
The storing and reading unit 57 searches the operation right management DB 5006 by using the communication IDs stored in the session management DB 5005 in step S907 as search keys and reads the items of operation right management information (records) including the communication IDs (step S908). Further, the storing and reading unit 57 searches the terminal management DB 5003 by using the communication IDs stored in the session management DB 5005 in step S907 as search keys and reads the corresponding counterpart name (step S908). Then, the operation right information creation unit 60 creates operation right information, based on the operation right management information and the counterpart name (step S908).
The session management unit 55 of the communication management system 50 transmits session information to the relay device 30 (step S909). In an example, the session information includes information such as the session ID created in step S907. The relay device 30 can acquire session information from the session management DB 5005, based on the session ID.
The session management unit 55 of the communication management system 50 transmits, to the communication terminal 10A, start instruction information indicating an instruction to start a session and the operation right information created in step S908 (step S910a). The session management unit 55 of the communication management system 50 also transmits, to the communication terminal 10X, start instruction information indicating an instruction to start a session and the operation right information created in step S908 (step S910b). The start instruction information includes a session ID, and the communication terminal 10 can acquire session information from the session management DB 5005, based on the session ID. As a result, in the communication terminal 10A, the display control unit 16 causes the display unit 109 to display an operation right information screen 900 illustrated in
The operation right information screen 900 displays the current setting states of operation rights. The operation right information screen 900 displays, for each operation-right application target (user's operation target) ID, an operation-right-set terminal (operation-right-set user) and the elapsed time of application of the operation right. The operation right information screen 900 also serves as a screen for starting video distribution. The operation right information screen 900 displays a “start” button 910 for starting video distribution, and a “stop” button 920 for stopping the start of video distribution.
In response to the operation input acceptance unit 12 accepting pressing of the “start” button 910, the transmitting/receiving unit 11 of the communication terminal 10A establishes a video and audio session with the relay device 30 (step S911a). In an example, the transmitting/receiving unit 11 of the communication terminal 10A may establish a session with the relay device 30 in response to receipt of the start instruction information, rather than in response to pressing of the “start” button 910. In this case, the operation right information illustrated in
The wide-angle image transmission unit 31 of the wide-angle image capturing device 9 transmits an equirectangular projection video to the communication terminal 10X (step S911c). In an example, when the communication terminal 10X establishes a session, the communication terminal 10X instructs the wide-angle image capturing device 9 to start capturing and transmitting an equirectangular projection video. In another example, the wide-angle image capturing device 9 may constantly transmit an equirectangular projection video to the communication terminal 10X while the power of the wide-angle image capturing device 9 is on. In another example, an equirectangular projection video may be transmitted before the establishment of a session.
The communication terminals 10A and 10X participate in a session having the same session ID and transmit and receive content data such as image data and audio data to and from each other to have, for example, a teleconference (step S912).
Next, a process in which the user a remotely operates the robot R by using the communication terminal 10A during video distribution will be described with reference to
First, a process (1) for remotely operating a telepresence robot will be described with reference to
In the communication terminal OA, in response to the operation input acceptance unit 12 accepting a remote operation by the user a, the transmitting/receiving unit 11 transmits operation information to the communication management system 50 (step S201). The operation information includes the communication ID of the user a, an operation-target ID for identifying a target to be remotely operated, and the content of the operation. The content of the operation includes driving the moving device 20 to cause the robot R to move straight, and causing the wide-angle image capturing device 9 to start capturing an image, for example. Then, the transmitting/receiving unit 51 of the communication management system 50 receives the operation information.
In the communication management system 50, the operation right checking unit 58 checks whether the user a indicated by the communication ID received in step S201 has the operation right for the operation target indicated by the operation-target ID received in step S201 (step S202). More specifically, the operation right checking unit 58 checks whether the pair of IDs including the communication ID and the operation-target ID received in step S201 matches a pair of IDs managed in the operation right management DB 5006.
If the user a has the operation right, the transmitting/receiving unit 51 transfers the operation information to the communication terminal 10X of the robot R (step S203). Then, the transmitting/receiving unit 11 of the communication terminal 10X receives the operation information. The inter-device communication unit 19d transmits a control instruction to the operation target (i.e., the wide-angle image capturing device 9 and the moving device 20) in accordance with the content of the operation (step S204).
On the other hand, if the user a does not have the operation right, the transmitting/receiving unit 51 transmits a notification indicating rejection of the remote operation to the communication terminal 10A from which the operation information is transmitted (step S205). The transmitting/receiving unit 11 of the communication terminal 10A receives the notification indicating the rejection. The display control unit 16 of the communication terminal 10A causes the display unit 109 to display a notification that the remote operation is rejected. In an example, the processing of step S205 is not performed, and the communication management system 50 leaves the remote operation rejected.
Then, the process (1) for remote operation using the operation right ends.
Subsequently, a process (2) for remotely operating a telepresence robot will be described with reference to
In the communication terminal 10A, in response to the operation input acceptance unit 12 accepting a remote operation by the user a, the transmitting/receiving unit 11 transmits operation information to the communication management system 50 (step S301). The operation information includes the communication ID of the user a, an operation-target ID for identifying a target to be remotely operated, and the content of the operation. The content of the operation includes driving the moving device 20 to cause the robot R to move straight, and causing the wide-angle image capturing device 9 to start capturing an image, for example.
Then, the transmitting/receiving unit 51 of the communication management system 50 receives the operation information.
The transmitting/receiving unit 51 of the communication management system 50 transfers the operation information to the communication terminal 10X of the robot R (step S302). Then, the transmitting/receiving unit 11 of the communication terminal 10X receives the operation information.
In the communication terminal 10X, the operation right checking unit 18 checks whether the user a indicated by the communication ID received in step S302 has the operation right for the operation target indicated by the operation-target ID received in step S302 (step S303). More specifically, the operation right checking unit 18 checks whether the pair of IDs including the communication ID and the operation-target ID received in step S302 matches a pair of IDs managed in the operation right management DB 1006.
If the user a does not have the operation right, the transmitting/receiving unit 11 of the communication terminal 10X transmits a notification indicating rejection of the remote operation to the communication management system 50 (step S305). Then, the transmitting/receiving unit 51 of the communication management system 50 receives the notification indicating the rejection. Further, the transmitting/receiving unit 51 transfers the notification indicating the rejection to the communication terminal 10A (step S306). In the communication terminal 10A, the display control unit 16 causes the display unit 109 to display a notification that the remote operation is rejected. In an example, the processing of steps S305 and S306 is not performed, and the communication terminal 10X leaves the remote operation rejected.
On the other hand, if the user a does not have the operation right in step S303, the processing of steps S305 and S306 is not performed. The inter-device communication unit 19d of the communication terminal 10X transmits a control instruction to the operation target (i.e., the wide-angle image capturing device 9 and the moving device 20) in accordance with the content of the operation (step S304).
Then, the process (2) for remote operation using the operation right ends.
As described below, operation rights may be transferred or set. A process for transferring an operation right and a process for setting an operation right according to a modification will be described.
Next, a process for transferring an operation right during video distribution will be described with reference to
While video and audio are transmitted and received via the relay device 30, the process for transferring an operation right is performed by a control session via the communication management system 50. The user a has an operation right for exclusively performing a remote operation on a predetermined operation target (in an example, the wide-angle image capturing device 9 and the moving device 20) of the robot R. While the communication terminal 10A, instead of the user a, may have an operation right, the following description will be given assuming that the user a has an operation right. A case where the user b requests the user a to transfer the operation right set to the user a will be described.
First, the user b presses a “transfer request” button 250 illustrated in
In response to the user b designating (or selecting) a desired operation-right application target, the operation input acceptance unit 12 accepts the designation (step S402). In
In response to the user b pressing the “request” button 410, the operation input acceptance unit 12 accepts pressing of the “request” button 410. The transmitting/receiving unit 11 of the communication terminal 10B transmits an operation-right transfer request to the communication management system 50 (step S403). The operation-right transfer request includes an application-target ID of the operation-right application target designated by the user b, and the communication ID of the user b from which the operation-right transfer request is sent. Then, the transmitting/receiving unit 51 of the communication management system 50 receives the operation-right transfer request.
In the communication management system 50, the storing and reading unit 57 searches the terminal management DB 5003 by using the communication ID received in step S403 as a search key and reads the corresponding counterpart name (step S404). In other words, the storing and reading unit 57 reads the name of the user b from which the operation-right transfer request is sent. Further, the storing and reading unit 57 searches the operation right management DB 5006 by using the application-target ID received in step S403 as a search key and reads the communication ID of the corresponding operation-right-set user to identify the request target (step S405).
Then, the transmitting/receiving unit 51 transmits an operation-right transfer request to the communication terminal that is the identified request target (in the illustrated example, the communication terminal 10A) (step S406). The operation-right transfer request includes the application-target ID received in step S403 and the request sender name, which is the counterpart name read in step S404. Then, the transmitting/receiving unit 11 of the communication terminal 10A receives the operation-right transfer request.
In the communication terminal 10A, the display control unit 16 extracts the information (record) related to the application-target ID received in step S406 from within the operation right information that has already been acquired in step S910a. Further, the display control unit 16 also creates a message using the request sender name received in step S406, and causes the display unit 109 to display a screen 450 for the “transferability of operation rights” illustrated in
Then, the operation input acceptance unit 12 accepts, from the user a, permission or rejection of the operation-right transfer request for each operation-right application target, and accepts pressing of the “set” button 460 (step S408). In
Then, the transmitting/receiving unit 11 of the communication terminal 10A transmits, to the communication management system 50, a request for changing (or maintaining) the setting of the operation right (step S409). The request includes, for each application-target ID, a result indicating a change or maintenance of the setting of the operation right. Then, the transmitting/receiving unit 51 of the communication management system 50 receives a request for changing (or maintaining) the setting of the operation right.
The communication management system 50 changes (or maintains) the operation right (step S410). More specifically, to change the setting of the operation right, the storing and reading unit 57 changes, in the operation right management DB 5006, the value in the “communication ID of operation-right-set terminal (operation-right-set user)” field corresponding to the application-target ID indicated in the request from the communication ID of the request target to the communication ID of the request sender. At this time, the storing and reading unit 57 resets the value for the elapsed time of application of the operation right to change the value to “00:00”. By contrast, to maintain the setting of the operation right, the storing and reading unit 57 does not change the operation right management DB 5006. Even a communication ID indicating the terminal ID of a communication terminal may be changed to a user ID instead of a terminal ID. Even a communication ID indicating a user ID may be changed to a terminal ID instead of a user ID.
Then, the transmitting/receiving unit 51 transmits result information to the communication terminal 10B as a response to the operation-right transfer request transmitted in step S403 (step S411). The result information includes a request result (permission or rejection) for each operation-right application target for which the operation-right transfer request has been made. Then, the transmitting/receiving unit 11 of the communication terminal 10B receives the result information.
Then, in the communication terminal 10B, the display control unit 16 causes the display unit 109 to display a screen 480 for “result of operation-right transfer request” illustrated in
In the “elapsed time of application of operation right” field, the value for the application target for which the operation-right transfer request is permitted is reset to “00:00”, and the value for the application target for which the operation-right transfer request is rejected remains unchanged because the setting is not changed.
The screen 480 also displays a “confirm” button 490 for the user b to close the screen 480 and return to the screen for video distribution (see
Then, the process for transferring an operation right ends.
Next, a process for setting an operation right will be described with reference to
While video and audio are transmitted and received via the relay device 30, the process for setting an operation right is performed by a control session via the communication management system 50. The user a has an operation right for exclusively performing a remote operation on a predetermined operation target (in an example, the wide-angle image capturing device 9 and the moving device 20) of the robot R. While the communication terminal 10A, instead of the user a, may have an operation right, the following description will be given assuming that the user a has an operation right. A case where the user a requests the explainer m to set the operation right will be described.
First, the user a presses a “setting request” button 250 illustrated in
In response to the user a designating (or selecting) a desired operation-right application target, the operation input acceptance unit 12 accepts the designation (step S402A). In
In response to the user a pressing the “request” button 410A, the operation input acceptance unit 12 accepts pressing of the “request” button 410A. The transmitting/receiving unit 11 of the communication terminal 10A transmits an operation-right setting request to the communication management system 50 (step S403A). The operation-right setting request includes an application-target ID of the operation-right application target designated by the user a, and the communication ID of the user a from which the operation-right setting request is sent. Then, the transmitting/receiving unit 51 of the communication management system 50 receives the operation-right setting request. The display control unit 16 causes the display unit 109 to display an indication that the operation-right setting request is being made for a period of time from when the transmitting/receiving unit 11 transmits the operation-right setting request to when the transmitting/receiving unit 11 receives result information that is a response to the request in step S411A described below.
Then, in the communication management system 50, the storing and reading unit 57 searches the terminal management DB 5003 by using the communication ID received in step S403A as a search key and reads the corresponding counterpart name (step S404A). In other words, the storing and reading unit 57 reads the name of the user a from which the operation-right setting request is sent. Further, the storing and reading unit 57 searches the operation right management DB 5006 by using the application-target ID received in step S403A as a search key and reads the communication ID of the corresponding operation-right-set user to identify the request target (step S405A). If the reading of the communication ID of the operation-right-set user is not successful, it is determined in advance that the request target is the explainer m.
Then, the transmitting/receiving unit 51 transmits an operation-right setting request to the communication terminal that is the identified request target (in an example, the communication terminal 10M) (step S406A). The operation-right setting request includes the application-target ID received in step S403A and the request sender name, which is the counterpart name read in step S404A. Then, the transmitting/receiving unit 11 of the communication terminal 10M receives the operation-right setting request.
In the communication terminal 10M, the display control unit 16 extracts the information (record) related to the application-target ID received in step S406A from within the operation right information that has already been acquired in step S910a. Further, the display control unit 16 also creates a message using the request sender name received in step S406A, and causes the display unit 109 to display a screen 450A for the “permissibility to set operation rights” illustrated in
The screen 450A also displays a “set” button 460A for setting whether the operation-right setting request is accepted for an item for which designation is set in the designation field, and a “cancel all” button 470A for canceling all designations.
Then, the operation input acceptance unit 12 accepts, from the explainer m, permission or rejection of the operation-right setting request for each operation-right application target, and accepts pressing of the “set” button 460A (step S408A). In
Then, the transmitting/receiving unit 11 of the communication terminal 10M transmits, to the communication management system 50, a request for setting or non-setting of the operation right (step S409A). The request includes, for each application-target ID, a result indicating setting or non-setting of the operation right. Then, the transmitting/receiving unit 51 of the communication management system 50 receives the request for setting or non-setting of the operation right.
The communication management system 50 sets (or leaves) the operation right (step S410A). More specifically, for setting of the operation right, the storing and reading unit 57 manages, in the operation right management DB 5006, the communication ID of the request target in the “communication ID of operation-right-set terminal (operation-right-set user)” field corresponding to the application-target ID indicated in the request. At this time, the storing and reading unit 57 starts counting the elapsed time of application of the operation right. By contrast, for non-setting of the operation right, the storing and reading unit 57 does not perform setting on the operation right management DB 5006 (leaves the operation right management DB 5006 unchanged).
Then, the transmitting/receiving unit 51 transmits result information to the communication terminal 10A as a response to the operation-right setting request transmitted in step S403 (step S411A). The result information includes a request result (permission or rejection) for each operation-right application target for which the operation-right setting request has been made. Then, the transmitting/receiving unit 11 of the communication terminal 10A receives the result information.
Then, in the communication terminal 10A, the display control unit 16 causes the display unit 109 to display a screen 480A for “results of operation-right setting request” illustrated in
The screen 480A also displays a “confirm” button 490A for the user a to close the screen 480A and return to the screen for video distribution (see
Then, the process for setting an operation right ends.
Next, application examples of this embodiment will be described with reference to
As illustrated in
The display control unit 16 of the communication terminal 10A causes the display unit 109 of the communication terminal 10A to display a display screen 200 illustrated in
The display area 210 also displays a plurality of operation icons 230 for remotely operating the robot R. The user a performs an operation (screen operation) on the operation icons 230 to remotely operate the robot R in the art museum. The information 220 related to the operation right and the operation icons 230 may be displayed at positions other than those illustrated in
The display screen 200 may display the button 250, as illustrated in
The display screen 200 further displays videos 241, 242, and 243 in the right part thereof. The video 241 is a video of the site A at which the communication terminal 10A is located. The videos 242 and 243 are transmitted from other sites. For example, the videos 241, 242, and 243 are videos of the users a, b, and c, respectively. The user a can perform video distribution in consideration of the facial expression of the user a and the facial expressions of the other persons.
In remote shopping, as illustrated in
In this embodiment, the moving device 20 that travels on land has been described as an example. In some embodiments, the moving device 20 may be a drone and fly in the air. In some embodiments, the moving device 20 may travel on the sea or move in water. In some embodiments, the moving device 20 may move underground, on a narrow road, or in the ground. In an example, the moving device 20 travels on land. The moving device 20 may move using wheels, move using multiple legs such as two legs, three legs, or four legs, or move using Caterpillar® tracks.
In this embodiment, the communication terminals 10 communicate with each other via the relay device 30. In some embodiments, the communication terminals 10 may communicate with each other without the intervention of the relay device 30. Such communication is performed via a communication protocol such as web real-time communication (WebRTC).
In this embodiment, for convenience of description, the communication management system 50 and the relay device 30 are described as separate devices. In some embodiments, a device having integrated functions of the communication management system 50 and the relay device 30 may provide the functions of the communication management system 50 and the functions of the relay device 30.
The communication system 1 may include a plurality of communication management systems 50. The functions of the communication management system 50 may be installed in a plurality of servers in a distributed manner. One or more of the databases included in the storage unit 5000 of the communication management system 50 may reside on the communication network 2.
As described above, in a case where a plurality of users are viewing a video captured by a remotely-operable mobile apparatus, it is desirable to appropriately manage control of remote operations to be performed on the remotely-operable mobile apparatus. Currently, a user who attempts to operate a remotely-operable mobile apparatus can access the remotely-operable mobile apparatus even if another user is operating the remotely-operable mobile apparatus. Accordingly, the remotely-operable mobile apparatus can be operated by various users in a random manner.
As a result, for example, the remotely-operable mobile apparatus that is moving to the right to travel to the destination under remote operation by a certain user may be remotely operated by a different user and move to the left, thereby changing the destination to a different place.
According to at least one embodiment described above, the use of the operation right allows smooth manipulation of a remotely-operable mobile apparatus such as the robot R even if a plurality of users remotely operate the remotely-operable mobile apparatus.
If a specific user is allowed to operate the robot R by remote control, no other user can operate the robot R by remote control. According to at least one embodiment described above, even if a specific user is allowed to exclusively operate a remotely-operable mobile apparatus such as the robot R by remote control, other users can also operate the remotely-operable mobile apparatus by remote control, based on the premise that various users are not allowed to remotely operate the remotely-operable mobile apparatus in a random manner.
For example, some users who view a video after the start of video distribution desire to exclusively operate the remotely-operable mobile apparatus by remote control. According to at least one embodiment described above, even after the start of video distribution, a specific user is allowed to remotely operate the remotely-operable mobile apparatus.
The above-described embodiments are illustrative and do not limit the present invention. Thus, numerous additional modifications and variations are possible in light of the above teachings. For example, elements and/or features of different illustrative embodiments may be combined with each other and/or substituted for each other within the scope of the present invention. Any one of the above-described operations may be performed in various other ways, for example, in an order different from the one described above.
The functionality of the elements disclosed herein may be implemented using circuitry or processing circuitry which includes general purpose processors, special purpose processors, integrated circuits, application specific integrated circuits (ASICs), digital signal processors (DSPs), field programmable gate arrays (FPGAs), conventional circuitry and/or combinations thereof which are configured or programmed to perform the disclosed functionality. Processors are considered processing circuitry or circuitry as they include transistors and other circuitry therein. In the disclosure, the circuitry, units, or means are hardware that carry out or are programmed to perform the recited functionality. The hardware may be any hardware disclosed herein or otherwise known which is programmed or configured to carry out the recited functionality. When the hardware is a processor which may be considered a type of circuitry, the circuitry, means, or units are a combination of hardware and software, the software being used to configure the hardware and/or processor.
