According to the above conventional technology, it is possible to exchange information between two electronic devices by using wireless communication even when connection through a wired line is not performed. Here, communication quality between the electronic devices varies according to an installation place or an installation direction of each of the electronic devices. However, it is difficult for a user to recognize and see whether the quality is high or low. Thus, it is important to set an optimal wireless communication environment in consideration of communication quality between the electronic devices.

6. Application example
The communication system 10 includes an information processing apparatus 100 and electronic devices 200 to 204. Note that in
Here, the information processing apparatus 100 can be a portable information processing apparatus including a display function. That is, the information processing apparatus 100 is a device which can be operated at hand by a user 20 and which is a mobile device. Note that each of the electronic devices 200 to 204 may or may not include a display function.
Also, each of the information processing apparatus 100 and the electronic devices 200 to 204 includes a wireless communication function with which it is possible to exchange information with a different device by using wireless communication. For example, the information processing apparatus 100 and the electronic devices 200 to 204 can perform wireless communication by a communication system of a wireless local area network (LAN). Also, the information processing apparatus 100 and the electronic devices 200 to 204 may perform wireless communication by a different communication system.
In such a manner, various wireless communication devices are arranged in a distributed manner in a certain area, whereby the communication system 10 is configured. Note that the information processing apparatus 100 can be held by the user 20.
Here, for example, the certain area indicates a place such as an office, a house, a factory, an airport, an educational institution (such as classroom in school), a cultural institution, a sport facility, a welfare institution, a medical facility (such as hospital), an assembly hall, an airport, a tourist facility, a commercial facility, or an accommodation facility.
Also, for example, each of the electronic devices 200 to 204 can be an electronic device such as a sensor, a television, a projector, a hard disk recorder, a speaker, a microphone, an access point, a personal computer (PC), or a display. Also, for example, each of the electronic devices 200 to 204 can be an electronic device such as a drone, a medical device, a surgical device, a patient tracking monitor, gaming device, a Blu-ray disc player, a printer, a light with a sensor, an automatic door, a security device, or a disaster prevention device. Also, for example, each of the electronic devices 200 to 204 is a tablet, a smartphone, a photo frame, a refrigerator, an air conditioner, an air cleaner, a vacuum cleaner (such as self-propelled vacuum cleaner), a laundry machine, a microwave, a toaster, a ventilation fan, or a radio.
Also, wireless communication performed between devices is realized, for example, by a communication method in which mutual connection with a peripheral electronic device is performed autonomously. Note that the peripheral electronic device is, for example, an adjacent electronic device or an adjoining electronic device.
Here, as a communication method in which mutual connection with a peripheral electronic device is performed autonomously, ad hoc communication or an ad hoc network has been known. In such a network, each electronic device can perform mutual communication with a peripheral electronic device without depending on a master station (such as control device). Thus, in an embodiment of the present technology, a description will be made with an ad hoc network or a mesh network as an example of a communication method in which mutual connection with a peripheral electronic device is autonomously performed.
In the ad hoc network, when a new electronic device is added to the periphery, the new electronic device can freely participate in the network. In such a manner, it is possible to increase a cover range of the network as the number of electronic devices (peripheral electronic device) is increased. That is, a cover range of the network can be increased as an electronic device is serially added.
Here, each of the information processing apparatus 100 and the electronic devices 200 to 204 can perform transfer of information, which is exchanged between different devices, in a bucket-brigade manner in addition to autonomous mutual connection with a different device in the periphery.
For example, a case where there is a device (such as electronic device 201) for which it is difficult to directly communicate with the electronic device 203 due to non-arrival of a radio wave is assumed. In such a manner, even when direct connection is difficult to be performed, the electronic device 202 which can directly communicate with the electronic device 203 transfers data of the electronic device 201 to the electronic device 203. Since the data is transferred in such a manner, the electronic device 203 and the electronic device 201 for which it is difficult to communicate with the electronic device 203 directly can exchange information through the electronic device 202. That is, the electronic device 201 and the electronic device 203 can communicate with each other through a relay station (electronic device 202).
A method of performing data transfer to each other (so-called bucket brigade) in such a manner and transferring information to a distant device is called multi-hop relay. Also, a network to perform multi-hop is generally known as a mesh network. Also, the communication system 10 is an example of a network in which a plurality of devices is connected to each other by one-on-one wireless communication. That is, in the communication system 10, each device is a system included in an ad hoc network or a mesh network.
For example, the electronic device 200 is an electronic device (such as speaker including memory) which can hold content (such as sound content (sound source) or image content (video with sound)) and can output the content from the own device or from a different electronic device. Also, each of the electronic devices 201 to 204 is a speaker which can output the content held in the electronic device 200.
In this case, the content held in the electronic device 200 can be transmitted to the electronic devices 201 to 204 by wireless communication and the content can be reproduced in each installation place of the electronic devices 201 to 204. For example, each of (or at least one of) the electronic devices 201 to 204 can reproduce content of an identical sound source. Also, for example, the electronic devices 201 to 204 can respectively reproduce content of different sound sources.
Here, since it is possible to exchange information by wireless communication, the user 20 can freely install the electronic devices 200 to 204.
However, in a case of using the wireless communication, a size, a radio wave environment, or the like may vary in a certain area depending on an installation place. Thus, when the user 20 freely installs the electronic devices 200 to 204, a part of the electronic devices may be installed in a place where a radio wave does not arrive. Also, for example, a communication path (path) which is not easily connected to a part of the electronic devices may be generated. Also, for example, a communication path (path) with which a load is applied only to a part of the electronic devices may be generated.
Also, it is difficult for the user 20 to understand which installation place of each of the electronic devices 200 to 204 makes it possible to secure many paths good for a wireless communication environment or to understand an arrangement in which performance as the communication system 10 becomes optimal (or preferable). Thus, after installing the electronic devices 200 to 204, the user 20 needs to make each of the electronic devices 200 to 204 output sound, to listen to the sound output, and to look for an installation place of each of the electronic devices 200 to 204. In such a manner, the user 20 needs to serially and appropriately move the electronic devices 200 to 204 and to look for an installation place of each of the electronic devices 200 to 204.
As described, there are various installation environments of electronic devices. Thus, it is difficult for the user 20 to understand which arrangement of the electronic devices 200 to 204 is a preferable arrangement method of the communication system 10. Also, for example, since installation places of the electronic devices 200 to 204 are distributed, performing an adjustment method of the electronic devices 200 to 204 is difficult.
Thus, in the first embodiment of the present technology, an example in which a user can easily understand an arrangement of electronic devices with which arrangement performance as the communication system 10 becomes optimal (or preferable) will be described.
[Example of Configuration of Information Processing Apparatus]
The information processing apparatus 100 includes a communication unit 110, an antenna 111, a control unit 120, a storage unit 130, a timer 140, a display unit 150, an operation reception unit 160, and a sound output unit 170. Also, these are connected to each other through a bus 180. The information processing apparatus 100 is, for example, a portable information processing apparatus which can be carried around by the user 20 (such as smartphone, tablet terminal, or mobile phone).
The communication unit 110 is a module (such as wireless local area network (LAN) modem) to perform transmission/reception of a radio wave through the antenna 111. For example, the communication unit 110 can perform wireless communication by a communication system of the wireless LAN. Also, for example, the communication unit 110 can perform wireless communication by ZigBee (registered trademark), near field communication (NFC), Bluetooth (BT (registered trademark)), or Bluetooth low energy (BLE). Also, for example, the communication unit 110 can perform wireless communication by a different communication system (such as visible light communication).
For example, based on the control by the control unit 120, the communication unit 110 can be connected to a different device and can exchange information with the device by using wireless communication. Also, for example, based on the control by the control unit 120, the communication unit 110 can transfer information, through a different device (first device), to a device (second device) different from the device (first device).
Also, the communication unit 110 may perform wireless communication using a radio wave (electromagnetic wave) and may perform wireless communication using a medium other than a radio wave (such as wireless communication using magnetic field). Note that the communication unit 110 is an example of an acquisition unit described in claims.
The control unit 120 controls each part of the information processing apparatus 100 based on a control program stored in the storage unit 130. For example, the control unit 120 is realized by a central processing unit (CPU). Also, for example, the control unit 120 performs signal processing of transmitted/received information.
For example, based on communication quality related to an electronic device which quality is acquired by the communication unit 110, the control unit 120 can output adjustment information to adjust a position and a direction of an antenna of the electronic device (for example, communication quality notification screen 340 illustrated in
The storage unit 130 is a memory to store various kinds of information. For example, in the storage unit 130, various kinds of information (such as control program) which is necessary for the information processing apparatus 100 to perform an intended operation is stored. Also, for example, in the storage unit 130, test data (calibration data) to transmit a test frame which is used by a different electronic device to measure communication quality is stored. Here, the communication quality is, for example, communication quality between electronic devices. For example, the communication quality can be understood as system communication performance of distributed and arranged electronic devices or as communication performance of each path in a case of performing data communication by using wireless communication. Also, in the storage unit 130, a management table (management table illustrated in
For example, a case of transmitting data from the communication unit 110 by using wireless communication is assumed. In this case, the control unit 120 processes information read from the storage unit 130, operation information input from the operation reception unit 160, or the like and generates a block of data to be actually transmitted (transmission packet). Then, the control unit 120 outputs the generated transmission packet to the communication unit 110. Also, after converting the transmission packet into a format of a communication system for actual transmission, the communication unit 110 transmits the converted transmission packet to the outside from the antenna 111.
Also, for example, in a case of receiving data in the communication unit 110 by using wireless communication, the communication unit 110 extracts a reception packet from the radio wave signal, which is received through the antenna 111, by signal processing performed by a reception device in the communication unit 110. Then, the control unit 120 interprets the extracted reception packet. As a result of the interpretation, when it is determined that the data is to be held, the control unit 120 writes the data into the storage unit 130. Also, when it is determined that the data is to be transferred to a different device, the control unit 120 transfers, to the communication unit 110, the data as a transmission packet to be transferred to a different device. Also, when it is determined that the data is to be output, the control unit 120 performs an output to the display unit 150 or to the sound output unit 170 or an output from an I/O interface (not illustrated) to the outside (such as external sound output apparatus).
The timer 140 is a timer to time various kinds of time. For example, the timer 140 times predetermined time at which the information processing apparatus 100 transmits a test frame. When the predetermined time is reached, the timer 140 gives a notification to the control unit 120.
The display unit 150 is a display unit to output various kinds of information based on the control performed by the control unit 120. As the display unit 150, for example, a display panel such as an organic electro luminescence (EL) panel or a liquid crystal display (LCD) panel can be used. As illustrated in
The operation reception unit 160 is an operation reception unit to receive an operation input performed by a user. The operation reception unit 160 outputs, to the control unit 120, operation information corresponding to the received operation input. The operation reception unit 160 is realized, for example, by a touch panel, a keyboard, a mouse, or a sensor (such as touch interface). Note that the display unit 150 and the operation reception unit 160 can be configured integrally by a touch panel on which a user can perform an operation input by touching a display surface with a finger or bringing the finger close to the surface.
The sound output unit 170 is a sound output unit (such as speaker) to output various kinds of sound information based on the control by the control unit 120.

Also, in each of
In the data rate management table 131, a data rate between the electronic devices 200 to 204 included in the communication system 10 is stored.
In the hop count management table 132, a hop count (number of transfers) between the electronic devices 200 to 204 included in the communication system 10 is stored. For example, “1” is stored as a hop count between electronic devices which can directly communicate with each other without a different electronic device therebetween. Also, for example, “2” is stored as a hop count between electronic devices which can indirectly communicate with each other through one electronic device.
By the hop count management table 132, it is easily understand which electronic device is to be used as a sound source, for example. Note that the sound source described herein means a source of distribution of content in a wireless environment. For example, an electronic device providing content may be used as a sound source. Also, in a case where an electronic device to provide content can be changed, it is possible to use, as the sound source, the electronic device which is the source of distribution.
In the time deviation information management table 133, arrival time deviation generated by data communication between the electronic devices 200 to 204 included in the communication system 10 is stored.
Note that the above communication quality is an example. Different communication quality (such as evaluation value (such as metric value)) may be measured and stored.
[Example of Configuration of Electronic Device]
The electronic device 200 includes a communication unit 210, an antenna 211, a control unit 220, a storage unit 230, a timer 240, and a sound output unit 250. Also, these are connected to each other through a bus 260. Note that the communication unit 210, the antenna 211, the control unit 220, the storage unit 230, the timer 240, and the sound output unit 250 correspond to parts with the same name in the information processing apparatus 100 illustrated in
The storage unit 230 is a memory to store various kinds of information. For example, in the storage unit 230, various kinds of information (such as control program) necessary for the electronic device 200 to perform an intended operation are stored. Also, in the storage unit 230, for example, content (such as sound content or video content) output from the sound output unit 250 or a different electronic device is stored. Also, in the storage unit 230, the communication quality management table 231 illustrated in
Also, two operation modes which are a reproduction mode and an adjustment mode can be set in the electronic device 200.
The reproduction mode is a mode (normal use mode) to perform reproduction (output from sound output unit 250) of content (content stored in storage unit 230 or content transmitted from different electronic device).
The adjustment mode is a mode (calibration mode) set in a case of adjusting an installation place of the electronic device 200 to an optimal place.
Each of these modes (reproduction mode and adjustment mode) can be set, for example, by using an operation member (such as switch or remote controller). For example, an operation member capable of switching the reproduction mode and the adjustment mode can be provided in a main body of the electronic device 200. In this case, the user 20 can switch modes physically.
Also, for example, the information processing apparatus 100 or a special terminal for control can be used as a remote controller. In this case, a mode switching signal is transmitted from the remote controller to the electronic device 200. Also, for example, it is possible to set the electronic devices 200 to 204 into the adjustment mode simultaneously by transmitting the mode switching signal to each of the electronic devices 200 to 204 from the remote controller.
Also, each mode (reproduction mode or adjustment mode) can be set based on control by a different device (such as control using control frame).
Here, when the adjustment mode is set, each of the electronic devices 200 to 204 measures communication quality related to data communication with a different electronic device. Then, each of the electronic devices 200 to 204 transmits the measurement result (communication quality) to the information processing apparatus 100. Here, as described above, the adjustment mode may be set based on an instruction from any of the electronic devices 200 to 204 or based on an instruction from the information processing apparatus 100. Here, a case where the adjustment mode is set in the electronic device 200 will be described as an example.
When the adjustment mode is set, the control unit 220 of the electronic device 200 periodically transmits, based on information from the timer 240, test data (test frame) stored in the storage unit 230 to the communication unit 210. For example, transmission can be performed by any of multicast, broadcast, and unicast. Note that the test data may not be data stored in the storage unit 230 and may be a random value generated and transmitted by the control unit 220. Also, for example, when the electronic device 200 is a speaker, test data including a feature of sound data can be used.
Also, a different electronic device also transmits a test frame in a similar manner. Thus, the electronic device 200 receives the test frame transmitted by the different electronic device. In such a manner, when the test frame from the different electronic device is received, the control unit 220 of the electronic device 200 measures communication quality with the different electronic device based on the test frame received in the communication unit 210. For example, the control unit 220 measures, as communication quality, a data rate, a received signal strength indicator (RSSI), a modulation and coding scheme (MCS), time deviation information, a hop count, or the like. Note that the time deviation information is information related to time from transmission from an electronic device, which is a transmission source of a test frame, until reception in the electronic device 200 (such as deviation time in transmission/reception time interval).
Also, the control unit 220 of the electronic device 200 records a measurement result based on the test frame received in the communication unit 210 (which result is communication quality with different electronic device) while associating the result with an electronic device which is the transmission source of the test frame. An example of the record is illustrated in
[Example of Contents in Communication Quality Management Table]
Note that in
In the communication quality management table 231, a measurement result based on the test frame (communication quality with different electronic device) is stored while being associated with the electronic device which is the transmission source of the test frame. Note that in
In such a manner, the control unit 220 of the electronic device 200 transmits communication quality, which is recorded in the communication quality management table 231, from the communication unit 210 to the information processing apparatus 100. In this case, all or a part of the communication quality recorded in the communication quality management table 231 can be transmitted to the information processing apparatus 100. Also, a different evaluation value may be calculated based on the communication quality recorded in the communication quality management table 231 and the evaluation value may be transmitted to the information processing apparatus 100. An example of a configuration of a reporting frame (report frame) used for transmission of the communication quality is illustrated in
[Example of Configuration of Reporting Frame]
For example, in a Body field 300 in the reporting frame, communication quality information is recorded while being associated with an electronic device. For example, terminal identification information of the electronic device 201 is stored into a first terminal identification information field 301 in the Body field 300 and communication quality information related to the electronic device 201 is stored into a first communication quality information field 302. Similarly, terminal identification information of the electronic device 202 is stored into a second terminal identification information field 303 in the Body field 300 and communication quality information related to the electronic device 202 is stored into a second communication quality information field 304. Also, each piece of information related to the electronic devices 203 and 204 can be stored in a similar manner.
In such a manner, each of the electronic devices 200 to 204 stores communication quality, which is measured in the own device or in a different electronic device, into a reporting frame and performs transmission to the information processing apparatus 100. However, a case where the own device or a different electronic device is not able to receive a test frame and it is not possible to measure communication quality with respect to any of electronic devices is assumed. In such a case, a reporting frame indicating that it is not possible to receive a test frame and to measure communication quality may be notified to the information processing apparatus 100.
Here, when receiving a reporting frame, each of the electronic devices 200 to 204 transfers the frame to the information processing apparatus 100. Also, when the information processing apparatus 100 receives the reporting frame, communication quality information included in the reporting frame is stored into each of the tables (data rate management table 131, hop count management table 132, and time deviation information management table 133 respectively illustrated in
[Example of Generation of Layout on Communication Quality Notification Screen]
The layout generation screen 310 is a display screen used in a case of generating a layout of a communication quality notification screen (such as communication quality notification screen 340 illustrated in
On the layout generation screen 310, an icon list display region 320 and a layout display region 330 are displayed.
In the icon list display region 320, a material in a case of generating a layout of a room (material included in room (such as living or bathroom)) or a material related to each device is displayed.
In the layout display region 330, a layout generated by a user is displayed. For example, the user selects the material displayed in the icon list display region 320 and displays the selected material in the layout display region 330.
For example, a living icon 321 is touched with a finger and the finger and moved to a predetermined position in the layout display region 330, as indicated by an arrow 322. Accordingly, a living region is formed in the layout display region 330. Also, a size or a shape of the living region can be arbitrarily changed by manual operation by the user (such as operation to decrease region or operation to increase region). Also, a different material can be generated in a similar manner. In
In such a manner, in the layout display region 330 in which each room is generated, an electronic device icon 323 is displayed at an installation place of each of the electronic devices 200 to 204. Also, in such a manner, in the layout display region 330 in which each room is generated, after an electronic device icon corresponding to each of the electronic devices 200 to 204 is arranged, the electronic devices 200 to 204 and the electronic device icons are associated with each other.
For example, when an electronic device icon arranged in the layout display region 330 is long-pressed (for example, for three second), an input region to input terminal identification information of an electronic device corresponding to the electronic device icon is displayed. Then, in the input region, it is possible to associate the electronic devices 200 to 204 with the electronic device icons by inputting terminal identification information of the electronic devices.
Also, for example, an electronic device icon arranged in the layout display region 330 is long-pushed (for example, for three seconds) and predetermined operation (such as pushing operation of predetermined button) is performed in an electronic device corresponding to the electronic device icon. By the predetermined operation, a control signal is transmitted from an electronic device corresponding to the electronic device icon to the information processing apparatus 100. Then, based on the control signal, it is possible to associate the electronic devices 200 to 204 with the electronic device icons.
In such a manner, a layout of a floor on the communication quality notification screen is generated and registered. Accordingly, a layout of the floor can be reused.
Note that in this example, an example of generating a layout of a single-story building (building with one floor) has been described. However, application to a case of generating a layout of a multi-story building (building with a plurality of floors) can be also performed. For example, in a case of generating a layout of a multi-story building (building with a plurality of floors), a layout display region is provided for each floor and the layout display regions are displayed in an array. Also, a layout displayed region of each floor may be displayed as a stereoscopic image. Accordingly, a hierarchical relationship in a building can be expressed.
[Example of Display on Communication Quality Notification Screen]
The communication quality notification screen 340 is a display screen to notify, to a user, communication quality reported from the electronic devices 200 to 204 (communication quality measured by transmission/reception of test frame in adjustment mode). The communication quality notification screen 340 is displayed, for example, after the electronic devices 200 to 204 are set into the adjustment mode by user operation in the information processing apparatus 100.
For example, on the communication quality notification screen 340, a system state notification bar 341, an assist information region 342, and a device state notification region 343 are displayed. Note that in
The system state notification bar 341 is a bar region to display a degree indicating whether data transmission from any electronic device to any electronic device can cause reproduction with no sound interruption in a hole system (which degree is state of whole system). Also, the assist information region 342 is a region displayed at a position indicating a degree. In the assist information region 342, contents to be improved (such as recommended information) are displayed in a balloon region. For example, an electronic device to which a data flow concentrates or an electronic device in which communication quality with a different electronic device is not high can be picked and information which prompts a user to move the electronic device can be displayed in the assist information region 342.
Here, it is preferable that a point to be improved is provided in such a manner that a path with each electronic device is increased. Thus, for example, based on positional information of an electronic device, the information processing apparatus 100 can pick an electronic device to which a data flow concentrates or an electronic device in which communication quality with a different electronic device is not high. For example, it can be recommended by the information processing apparatus 100 to move an electronic device (such as electronic device 202) around the center of a room. For example, in
In such a manner, for example, the information processing apparatus 100 can analyze each kind of communication quality and can provide, as recommended information, movement of an electronic device or changing of a direction thereof to a user (for example, by displaying in assist information region 342).
Note that in the system state notification bar 341, for example, it is indicated that a state becomes better on a left side and improvement becomes necessary on a right side. Note that a display method of the system state notification bar 341 illustrated in
In the device state notification region 343, a layout of a room, which is registered by using the layout generation screen 310, and communication quality between electronic devices are displayed. The communication quality can be displayed, for example, based on each table stored in the storage unit 130 (such as each of tables respectively illustrated in
Also, for example, communication quality between electronic devices is schematically indicated by a sign (such as arrow) in such a manner that the communication quality between the electronic devices is easily recognized. In
Note that a sign (such as arrow) indicating communication quality between electronic devices can be displayed only between electronic devices in which a path is established. Also, a sign (such as arrow) indicating communication quality between electronic devices can be displayed, for example, by performing threshold determination. For example, in a case where reception data rate is equal to or higher than 5 Mbs, a sign indicating that communication quality is high (arrow indicated by solid thick line) is displayed. Also, for example, in a case where a reception data rate is lower than 1 Mbs, a sign indicating that communication quality is low (arrow indicated by dotted narrow line) is displayed.
Also, a sign indicating communication quality between electronic devices may be displayed in a different display mode. For example, an arrow indicating, in different colors, whether communication quality is high or low may be displayed. Also, for example, whether communication quality is high or low may be displayed in different icons.
Also, communication quality of the electronic devices 200 to 204 is periodically reported to the information processing apparatus 100. Thus, when receiving a reporting frame from each of the electronic devices 200 to 204, the information processing apparatus 100 preferably performs an update to the latest value and performs a display based on the received reporting frame.
As illustrated in
In such a manner, the user can see the communication quality notification screen 340 and can move the electronic device 202 with low communication quality to a different place. Then, by checking the communication quality notification screen 340 again after the electronic device 202 is moved, a place in a room to which place the electronic device 202 is moved and at which place system performance is improved can be easily checked.
In such a manner, when there is an electronic device with low communication quality as a system in a mesh network, it is possible to move the electronic device to a place where communication quality as a system is improved. That is, it is possible to arrange each electronic device to a place intended by a user. In this case, by setting the adjustment mode in each electronic device, the user can adjust an installation place of each electronic device while looking at the information processing apparatus 100 at hand.
In such a manner, the control unit 120 of the information processing apparatus 100 can display the communication quality notification screen 340 onto the display unit 150. On the communication quality notification screen 340, a spatial image indicating a space in which the electronic devices 200 to 204 are installed and a device image indicating a position in the space at which position each of the electronic devices 200 to 204 is installed can be also displayed. Also, the control unit 120 can display communication quality related to the electronic devices 200 to 204 while associating the quality with these devices.
Also, the control unit 120 can display, onto the display unit 150, adjustment information (such as assist information region 342) suggesting a position and a direction of an antenna of each of the electronic devices 200 to 204 for improvement of communication quality in the mesh network. Also, based on the acquired communication quality, the control unit 120 can display a state image indicating a state of the communication quality in the mesh network (which image is, for example, system state notification bar 341 or assist information region 342) onto the display unit 150.
Note that as communication quality, for example, communication quality between the electronic devices 200 to 204 which quality is measured by the electronic devices 200 to 204 or communication quality between the information processing apparatus 100 and each of the electronic devices 200 to 204 can be displayed.
[Example of Setting of Adjustment Mode]
Next, an example of a case of adjusting an installation place of each of the electronic devices 200 to 204 will be described.
First, the user 20 installs the electronic devices 200 to 204 at arbitrary positions and activates the electronic devices 200 to 204. In this case, initial setting (such as setting operation of ID or password) for configuration of a mesh network is performed manually or automatically by the electronic devices 200 to 204. Note that in a case where the electronic devices 200 to 204 are set devices (such as set speakers), it is possible to configure a mesh network automatically by the initial setting (ID or password).
In such a manner, a mesh network (such as set speaker network) is configured by the electronic devices 200 to 204. Subsequently, the user 20 makes the information processing apparatus 100 participate in the mesh network. For example, initial setting (such as setting operation of ID or password) for participation in the mesh network is performed manually or automatically.
Then, the user 20 uses the information processing apparatus 100 and generates a layout of a room and an arrangement layout of the electronic devices 200 to 204. For example, by using the layout generation screen illustrated in
Then, the user 20 sets the adjustment mode in each of the electronic devices 200 to 204. An example of communication of when the adjustment mode is set in each of the electronic devices 200 to 204 (example of measurement of communication quality and example of report of measurement result) is illustrated in
[Example of communication]
When the adjustment mode is set, each of the electronic devices 200 to 204 transmits a test frame to an electronic device in a periphery (401 and 407). For example, each of the electronic devices 200 to 204 can periodically transmit a test frame in a broadcast, unicast, or multicast frame. Note that in
Also, each of the electronic devices 200 to 204 receives the test frame transmitted from the electronic device in the periphery (402 and 408). Then, based on the received test frame, each of the electronic devices 200 to 204 measures communication quality (such as RSSI or actually-transmitted data rate) (403 and 409).
Then, each of the electronic devices 200 to 204 reports the measurement result to the information processing apparatus 100 (404, 405, 410, and 411). For example, communication quality information related to each electronic device is included in the reporting frame illustrated in
Also, the information processing apparatus 100 which receives the measurement result from each of the electronic devices 200 to 204 records the measurement result (406 and 412). For example, recording into each of the tables respectively illustrated in
Note that a report may be given to the information processing apparatus 100 each time a test frame is received. Also, a value in which a measurement result in a certain period of time is corrected (or calculated value (such as averaged value)) may be reported periodically or irregularly.
[Example of Operation of Electronic Device]
First, the control unit 220 of the electronic device 200 determines whether the adjustment mode is set (step S801). When the adjustment mode is not set (that is, when reproduction mode is set) (step S801), an operation in the communication quality measurement processing is ended.
When the adjustment mode is set (step S801), the control unit 220 determines whether timing is transmission timing of a test frame based on information from the timer 240 (step S802). In a case of the transmission timing of a test frame (step S802), the control unit 220 makes the communication unit 210 transmit the test frame (step S803).
When the timing is not the transmission timing of a test frame (step S802), the control unit 220 determines whether a test frame is received from a different electronic device (step S804). When no test frame is received from the different electronic device (step S804), the processing goes back to step S801.
When the test frame is received from the different electronic device (step S804), the control unit 220 measures communication quality related to the electronic device which transmits the test frame (step S805). Subsequently, the control unit 220 transmits the measurement result (communication quality) to the information processing apparatus 100 (step S806). Note that whichever of transmission processing and reception processing of a test frame may be performed first. Also, when it is possible to perform the transmission processing and reception processing of a test frame simultaneously, the processing can be performed simultaneously.
[Example of Operation of Information Processing Apparatus]
First, the control unit 120 of the information processing apparatus 100 determines whether the adjustment mode is set (step S811). When the adjustment mode is not set (step S811), an operation in the communication quality notification processing is ended.
When the adjustment mode is set (step S811), the control unit 120 determines whether a reporting frame is received from the electronic device (step S812). When no reporting frame is received from the electronic device (step S812), the processing goes back to step S811.
When the reporting frame is received from the electronic device (step S812), the control unit 120 performs aggregation processing of communication quality information included in the reporting frame (step S813). Then, the control unit 120 updates contents in each table based on the aggregation result (step S814).
Subsequently, the control unit 120 displays communication quality notification screen onto the display unit 150 based on the updated contents in each table (step S815). For example, as illustrated in
In the first embodiment of the present technology, an example in which the electronic device measures communication quality and gives notification to the information processing apparatus has been described.
For example, a case of outputting high quality data (such as high-resolution audio source) in an environment illustrated in
In such a case, it is considered that it becomes easy to purchase a new electronic device in a case where it is possible to simulate how communication quality is improved when the new electronic device participates in the mesh network. Then, in the second embodiment of the present technology, an example in which an information processing apparatus measures and acquires communication quality instead of a new electronic device will be described. That is, an information processing apparatus 100 to which each of electronic devices 200 to 204 reports reception quality is assumed as one electronic device. Then, an example of a case of simulating how communication quality as a system turns out when a new electronic device is added to a mesh network including the electronic devices 200 to 204 will be described.
Note that a configuration of each apparatus in the second embodiment of the present technology is substantially identical to the information processing apparatus 100 and the electronic devices 200 to 204 which are illustrated, for example, in
[Example of Communication]
Also, in
Note that
Similarly to
Also, the information processing apparatus 100 receives a test frame transmitted from the electronic device in the periphery (424 and 432). Then, the information processing apparatus 100 measures communication quality (such as RSSI or actually transmitted data rate) based on the received test frame (426 and 433).
Subsequently, the information processing apparatus 100 records the measurement result (427 and 434). In such a manner, the information processing apparatus 100 held by a user 20 can be assumed as an electronic device and can participate in the mesh network. In this case, communication quality related to a position where the information processing apparatus 100 exists can be measured. Accordingly, similarly to the electronic devices 200 to 204, the communication quality related to the information processing apparatus 100 can be displayed on a communication quality notification screen.
[Example of Communication of when the Information Processing Apparatus Transmits Test Frame]
In
Note that communication processing illustrated in
When an adjustment mode is set, the information processing apparatus 100 transmits a test frame to an electronic device in a periphery (451). Also, the electronic device 201 which receives the test frame transfers the test frame to the electronic device 200 (452 to 454).
Also, each of the electronic devices 200 and 201 receives the test frame transmitted from the electronic device in the periphery and the information processing apparatus 100 (452 and 454). Then, based on the received test frame, each of the electronic devices 200 and 201 measures communication quality (such as RSSI or actually-transmitted data rate) (455 and 459).
Then, each of the electronic devices 200 and 201 reports the measurement result to the information processing apparatus 100 (456, 457, and 460 to 463). Subsequently, the information processing apparatus 100 records the measurement result (458 and 464).
[Example of Display on Communication Quality Notification Screen]
The communication quality notification screen 350 is a modification example of the communication quality notification screen 340 illustrated in
As illustrated in
In such a manner, a control unit 120 of the information processing apparatus 100 can display the communication quality notification screen 350 onto the display unit 150. On the communication quality notification screen 350, an apparatus image indicating a position where the information processing apparatus 100 exists in a space in which the electronic devices 200 to 204 are installed can be displayed. Also, on the communication quality notification screen 350, communication quality related to the information processing apparatus 100 and the electronic devices 200 to 204 can be displayed while being associated with each device.
[Example of Operation of Information Processing Apparatus]
When the adjustment mode is set (step S821), the control unit 120 of the information processing apparatus 100 determines whether the own apparatus is set to measure communication quality (step S822). In a case where the own apparatus is also set to measure communication quality (step S822), the processing goes to step S827. In a case where the own apparatus is not set to measure the communication quality (step S822), the processing goes to step S823.
Also, the control unit 120 of the information processing apparatus 100 aggregates and records the measurement result (communication quality) which is measured by the own apparatus (step S831).
In each of the first and second embodiments of the present technology, an example of notifying communication quality related to a fixed electronic device has been described.
Here, an electronic device which is movable (for example, which moves or rotates) autonomously or according to user operation (which device is, for example, self-propelled vacuum cleaner, a self-propelled speaker, or robot) can be considered. In a case of performing adjustment for installation of such a mobile electronic device, it is possible to measure communication quality and to set an optimal environment while moving the electronic device. Thus, an example of adjustment method in a case of installing a mobile electronic device will be described in the third embodiment of the present technology.
Note that a configuration of each apparatus in the third embodiment of the present technology is substantially identical to the information processing apparatus 100 and the electronic devices 200 to 204 which are illustrated, for example, in
[Example of Display of Communication Quality Notification Screen Related to Mobile Electronic Device]
The communication quality notification screen 360 is a modification example of the communication quality notification screen 340 illustrated in
For example, when the adjustment mode is set, each of the electronic devices 200 to 204 serially rotates the own device autonomously or according to the control from the information processing apparatus 100 and measures communication quality in each direction (such as eight direction). In this case, for example, the information processing apparatus 100 can specify one of the electronic devices 200 to 204 as an electronic device a direction of which is to be changed (specified electronic device) and can assume that the other electronic devices are fixed. Then, the information processing apparatus 100 can make each electronic device measure communication quality. Then, after communication quality is measured in each direction of the specified electronic device, a different electronic device is specified as an electronic device a direction of which is to be changed (specified electronic device) and the specified electronic device measures communication quality in all directions. In such a manner, an electronic device a direction of which is to be changed (specified electronic device) is changed according to a predetermined rule and communication quality in each of the directions (such as eight direction) is measured in each combination of the electronic device.
Then, each of the electronic devices 200 to 204 serially reports the measurement result (communication quality) to the information processing apparatus 100 while associating the result with the measured direction. As illustrated in
For example, a sign (such as arrow) indicating communication quality measured in eight directions is displayed around each of the icons 370 to 374 indicating the electronic devices 200 to 204. In
Also, when acquiring the communication quality measured with respect to each combination of the electronic devices, the information processing apparatus 100 selects a direction with the highest communication quality for each electronic device based on the acquired communication quality. Then, the information processing apparatus 100 notifies the selected direction to each electronic device by using wireless communication and performs control in such a manner that each electronic device rotates in the selected direction. In this case, the information processing apparatus 100 notifies a direction with the highest communication quality to each electronic device and makes each electronic device rotate automatically in the notified direction. Alternatively, the information processing apparatus 100 may transmit control information to rotate each electronic device in the direction with the highest communication quality and each electronic device may rotate based on the control information.
Also, the information processing apparatus 100 can exclude a direction with obviously low communication quality. In this case, the information processing apparatus 100 may perform a display which gives a warning for an electronic device facing the direction with the obviously low communication quality (which display is, for example, blink display of icon 370 to 374 or display thereof in red).
Also, when the direction with obviously low communication quality is excluded, the information processing apparatus 100 can display a direction with high communication quality for a user by searching for a direction other than the direction with obviously low communication quality.
In such a manner, the control unit 120 of the information processing apparatus 100 can display, as communication quality related to the electronic devices 200 to 204, communication quality measured in a plurality of installation directions (such as eight direction) of each electronic device while associating the quality with each of the installation directions.
Also, each of the electronic devices 200 to 204 can be a mobile device. In this case, the control unit 120 can generate control information to move the electronic devices 200 to 204 and can transmit the control information to the electronic devices 200 to 204.
[Example of Contents in Electronic Device Management Table]
Here, the information processing apparatus 100 can manage whether an electronic device communication quality of which is to be measured is a stationary electronic device or a mobile electronic device (such as mobile terminal). Thus, an example of the management is illustrated in
In the electronic device management table 134, information (stationary/mobile and function) related to each electronic device is stored. In such a manner, the information processing apparatus 100 can understand whether an electronic device, communication quality of which is to be measured, is a stationary device or a mobile device (such as mobile terminal). Also, by collecting information of a function of each electronic device, the information processing apparatus 100 can understand whether it is possible to move the electronic device.
For example, in a case of the stationary device, it can be assumed that there is a lot of power. Thus, it is possible to provide recommended information in such a manner that the number of paths with different electronic devices is increased. Also, it is possible to provide recommended information in consideration of performance of an electronic device.
Note that in the third embodiment of the present technology, an electronic device which can rotate the own device has been described as an example. However, it is also possible to display communication quality in a similar manner with respect to an electronic device which can move the own device. In this case, for example, communication quality can be measured by serially moving an electronic device in a movable range.
In the third embodiment of the present technology, an example of installing a mobile electronic device has been described. Here, an information processing apparatus which acquires and displays communication quality related to an electronic device may be moved (for example, moved or rotated) autonomously or according to user operation. In a case of using such a mobile information processing apparatus, it is possible to acquire communication quality and to set an optimal environment while moving the information processing apparatus.
Thus, in the fourth embodiment of the present technology, an example of using a mobile information processing apparatus will be described.
Note that a configuration of an electronic device in the fourth embodiment of the present technology is substantially identical to the electronic devices 200 to 204 illustrated, for example, in
[Example of Configuration of Information Processing Apparatus]
The information processing apparatus 500 includes a communication unit 510, an antenna 511, a control unit 520, a storage unit 530, a timer 540, a display unit 550, an operation reception unit 560, a sound output unit 570, a sensor 581, an actuator 582, and a motor 583. Also, these are connected to each other through a bus 580. Also, the information processing apparatus 500 is a robot which can move autonomously or by remote control (such as self-propelled vacuum cleaner which periodically and automatically perform cleaning, mobile self-propelled speaker, or humanoid robot).
Note that the communication unit 510, the antenna 511, the control unit 520, the storage unit 530, the timer 540, the display unit 550, the operation reception unit 560, and the sound output unit 570 corresponds to parts with the identical names in
The sensor 581 is a sensor to detect a state of the information processing apparatus 500 and outputs detected sensor information to the control unit 520. Accordingly, the control unit 520 can detect a position or a direction of the information processing apparatus 500. Note that the sensor 581 includes, for example, a global positioning system (GPS) sensor which can acquire positional information, a gyro sensor which can detect a direction, an orientation sensor which can detect an orientation, or an obstacle sensor for avoiding collision (sensor to detect obstacle and to avoid obstacle).
The actuator 582 is a drive device to drive a part or the whole of the information processing apparatus 500 based on control by the control unit 520. The actuator 582 is used, for example, in a case of performing a rotation to change a direction of the information processing apparatus 500. Also, for example, the actuator 582 is used to change a direction or an angle of the antenna 511.
The motor 583 is a drive device to move the information processing apparatus 500 based on the control by the control unit 520. For example, the motor 583 moves the information processing apparatus 500 by driving a wheel provided in a lower part of the information processing apparatus 500.
[Example of Record of Communication Quality at Each Place]
In
For example, the control unit 520 of the information processing apparatus 500 measures communication quality by serially moving the information processing apparatus 500 from the places P1 to Pz. For example, the information processing apparatus 500 receives a test frame from each of electronic devices 200 to 204 and measures communication quality of each of the electronic devices 200 to 204 while moving in a self-propelled manner. In this case, a period of time for measurement may be a period of time until the certain number of frames are received from each of the electronic devices 200 to 204 or may be a predetermined period of time (such as one minute). In such a manner, the information processing apparatus 500 performs the measurement while temporarily stopping at each of the positions P1 to Pz during the measurement time.
Also, the control unit 520 records, into the communication quality management table 700, the measured communication quality of the electronic devices 200 to 204 at each of the places P1 to Pz. For example, the information processing apparatus 500 moves to the place P1 and communication quality related to each of the electronic devices 200 to 204 which quality is measured at the place P1 is recorded while being associated with P1 in the communication quality management table 700, as indicated by an arrow. Note that the communication quality stored into the communication quality management table 700 may be information described in the first to third embodiments of the present technology (such as contents in management table illustrated in
Also, at each place, the information processing apparatus 500 may change a direction of the own apparatus and may measure communication quality in each direction. For example division into eight directions can be performed and communication quality can be measured while the information processing apparatus 500 is temporarily stopped in each direction. An example of the recording is illustrated in

Also, as illustrated in
By user operation, a list of an intended electronic device can be selected, switched to an upper side, and displayed.
Also, for example, it is possible to compose and display a color of each item by superimposing colored matrices (list 373) at places. In such a manner, by composing a color, it is possible to display communication quality in which performance of each of the electronic devices 200 to 204 at each place (such as place P1) is considered can be displayed in a manner visually recognized easily. That is, it is possible to display communication quality in a display mode easily recognized by the user.
[Example of Communication]
First, an adjustment mode is set in each of the electronic devices 200 and 201. That is, the information processing apparatus 500 transmits a setting frame to the electronic devices 200 and 201 which participate in the same network (601 to 604). The setting frame is an instruction frame to notify that data collection of communication quality is to be started.
Each of the electronic devices 200 and 201 which receives the setting frame sets an adjustment mode based on the received setting frame. In such a manner, when the adjustment mode is set, each of the electronic devices 200 and 201 transmits a frame indicating that setting is completed to the information processing apparatus 500 (605 to 608).
Subsequently, each of the electronic devices 200 and 201 transmits a test frame to the information processing apparatus 500 (609, 610, 613, and 614). The information processing apparatus 500 which receives the test frame measures the communication quality based on the received test frame (611 and 615). Then, the information processing apparatus 500 records the measurement result (612 and 616).
In such a manner, transmission of a test frame from each of the electronic devices 200 and 201 and measurement and recording of communication quality performed by the information processing apparatus 500 are performed periodically or irregularly. Note that these are not illustrated in
Subsequently, in a case of ending the adjustment mode (performance evaluation mode), the information processing apparatus 500 transmits a test ending frame to the electronic devices 200 and 201 (617 to 620). The test ending frame is a frame to give notification to end the adjustment mode (performance evaluation mode). Each of the electronic devices 200 and 201 which receives the test ending frame releases the adjustment mode.
Note that measurement time of communication quality (setting time of adjustment mode) may be previously determined and the electronic devices 200 and 201 may automatically end the adjustment mode when the measurement time is over. For example, measurement time is included in a setting frame which is transmitted first by the information processing apparatus 500. In this case, when receiving the setting frame, each of the electronic devices 200 and 201 sets the adjustment mode and ends the adjustment mode automatically when the measurement time included in the setting frame is over.
[Example of Communication]
Note that each processing (621 to 628 and 641 to 644) illustrated in
The information processing apparatus 500 transmits a test frame to each of the electronic devices 200 and 201 (629, 630, 635, and 636). Each of the electronic devices 200 and 201 which receive the test frame measures communication quality based on the received test frame (631 and 637). Then, each of the electronic devices 200 and 201 transmits the measurement result to the information processing apparatus 500 (632, 633, 638, and 639). In this case, the information processing apparatus 500 measures communication quality based on the frame transmitted from each of the electronic devices 200 and 201 (633 and 639). Then, the information processing apparatus 500 records the measurement result (including received measurement result) (634 and 640).
In such a manner, transmission of a test frame to each of the electronic devices 200 and 201 and measurement and recording of communication quality performed by the information processing apparatus 500 are performed periodically or irregularly. Note that these are not illustrated in
Note that similarly to
In such a manner, the mobile information processing apparatus 500 can measure reception performance of a frame from a different electronic device while moving. Then, the data can be collected and put together. Accordingly, a preferable arrangement and direction of an electronic device can be estimated without movement of a user. Also, since the information processing apparatus 500 acquires communication quality automatically, the user can see the data whenever he/she intends.
[Example of Operation of Electronic Device]
First, the control unit 220 of the electronic device 200 determines whether a setting frame is received (step S841). When the setting frame is not received (step S841), an operation in the communication quality measurement processing is ended.
When the setting frame is received (step S841), the control unit 220 sets the adjustment mode and transmits setting completion to the information processing apparatus 500 (step S842).
Subsequently, the control unit 220 determines whether timing is transmission timing of a test frame based on information from a timer 240 (step S843). In a case of the transmission timing of a test frame (step S843), the control unit 220 makes the communication unit 210 transmit the test frame (step S844).
When the timing is not the transmission timing of a test frame (step S843), the control unit 220 determines whether a test ending frame is received (step S845). When the test ending frame is not received (step S845), the processing goes back to step S843.
When the test ending frame is received (step S845), an operation in the communication quality measurement processing is ended.
[Example of Operation of Information Processing Apparatus]
First, the control unit 520 of the information processing apparatus 500 determines whether the adjustment mode is set (step S851). When the adjustment mode is not set (step S851), an operation in the communication quality measurement processing is ended.
When the adjustment mode is set (step S851), the control unit 520 transmits the setting frame to each electronic device (step S852). Subsequently, the control unit 520 determines whether setting completion is received from all electronic devices (step S853). When setting completion is not received from all of the electronic devices (step S853), monitoring is kept performed.
When the setting completion is received from all of the electronic devices (step S853), it is determined whether a test frame is received (step S854). When the test frame is not received (step S854), the processing goes to step S858.
When the test frame is received (step S854), the control unit 520 measures communication quality based on the test frame (step S855). Subsequently, the control unit 520 performs aggregation processing of the communication quality and updates contents in each table (step S856).
Then, the control unit 520 displays a communication quality notification screen onto the display unit 150 based on the updated contents in each table (step S857).
Subsequently, the control unit 520 determines whether timing is the test ending timing based on the information from the timer 540 (step S858). In a case of the test ending timing (step S858), the control unit 520 makes the communication unit 510 transmit the test ending frame (step S861).
When the timing is not the test ending timing (step S858), the control unit 520 determines whether the timing is update timing to update a position or a direction of the information processing apparatus 500 (step S859). In a case of the update timing (step S859), the control unit 520 changes a position or a direction of the information processing apparatus 500 (step S860). When the timing is not the update timing (step S859), the processing goes back to step S854.
[Example of Operation of Electronic Device]
Note that the processing procedure illustrated in
The control unit 220 of the electronic device 200 determines whether the test frame is received (step S873). When the test frame is not received (step S873), the processing goes to step S876.
When the test frame is received (step S873), the control unit 220 measures communication quality based on the test frame (step S874). Subsequently, the control unit 220 transmits the measurement result (communication quality) to the information processing apparatus 500 (step S875).
[Example of Operation of Information Processing Apparatus]
Note that the processing procedure illustrated in
The control unit 520 determines whether timing is transmission timing of the test frame based on information from the timer 540 (step S884). In a case of the transmission timing of a test frame (step S884), the control unit 520 makes the communication unit 510 transmit a test frame (step S885). When the timing is not transmission timing of a test frame (step S884), the processing goes to step S886.
Subsequently, the control unit 220 determines whether a reporting frame is received (step S886). When the reporting frame is not received (step S886), the processing goes to step S890.
When the reporting frame is received (step S886), the control unit 520 measures communication quality based on the reporting frame (step S887). Also, the control unit 520 performs aggregation processing of communication quality included in the reporting frame (step S887). Then, the control unit 520 updates contents in each table based on the aggregation result (step S888).
Subsequently, the control unit 520 displays a communication quality notification screen onto the display unit 150 based on the updated contents in each table (step S889).
In such a manner, the control unit 520 of the information processing apparatus 500 can move the information processing apparatus 500 and can use communication quality related to the electronic devices 200 to 204 which quality is measured serially after the movement. Also, the control unit 520 can display, onto the display unit 550, a spatial image indicating a space in which the electronic devices 200 to 204 are installed and a positional image (P1 to Pz) indicating a position in the space at which position communication quality is measured after the movement of the information processing apparatus 500. In this case, the control unit 520 can display communication quality measured at each position while associating the quality with the position.
In such a manner, each of the information processing apparatuses 100 and 500 can display various kinds of information related to a communication system based on the communication quality measured by the electronic devices 200 to 204 (or own apparatus). For example, each of the information processing apparatuses 100 and 500 can calculate and display a degree of system quality which can be kept at a place where a source device is installed. Note that required communication quality is different depending on a communication system. For example, in a communication system which needs to transmit/receive a large amount of data in real time, it is preferable that a reception interval deviation in a transmission/reception frame is small, a hop count is low, and a communication rate is high. On the other hand, depending on a communication system, there may be a case where quality with which a speech can be heard with an ear of a human is enough. Thus, according to a used communication system, a method of displaying a degree of communication quality as a communication system can be classified by levels and changed. The change may be performed based on user operation or by the following manner. That is, performance information or the like of each electronic device is acquired by the information processing apparatus and the information processing apparatus automatically performs the change based on the performance information or the like.
In the first to fourth embodiments of the present technology, an example in which an information processing apparatus handles communication quality measured by each device has been described. It is considered that information more useful for a user can be provided by aggregating and using the communication quality.
Thus, in the fifth embodiment of the present technology, an example of handling communication quality by using a cloud service will be described.
[Example of Configuration of Communication System]
The communication system 30 includes a network 31, an access point 32, a base station 33, and information processing apparatuses 40, 100, and 500. The communication system 30 is, for example, a communication system to realize a cloud service.
The network 31 is a network (such as public line) such as a telephone network or the Internet. The access point 32 is an access point to connect information processing apparatus by using wireless communication. The base station 33 is a mobile communication base station (NodeB) to connect the information processing apparatus by using wireless communication.
A server 750 is an information processing apparatus to acquire information transmitted from the information processing apparatuses 40, 100, and 500. Also, the server 750 provides information to the information processing apparatuses 40, 100, and 500.
For example, when purchasing electronic devices 200 to 204, the user acquires, from the server 750, an application to display communication quality in a manner easily recognized by the user. Subsequently, by using the application, the user inputs an arrangement of an electronic device and a floor layout of a room in the information processing apparatus 100 and saves the data (layout information) into the information processing apparatus 100. Also, the information processing apparatus 100 saves communication quality (communication quality information) measured by each electronic device into the information processing apparatus 100.
In such a manner, each piece of information stored in the information processing apparatus 100 (such as layout information or communication quality information) can be provided by the user to a service in the network. For example, each piece of information stored in the information processing apparatus 100 (such as layout information or communication quality information) is transmitted to the server 750 in such a manner that the information can be handled by the server 750.
Accordingly, the server 750 can acquire layout information related to a room of each user or communication quality information in the layout. Then, the server 750 can generate various kinds of information by analyzing and learning these pieces of information (such as layout information and communication quality information). For example, information related to an arrangement or a direction of an electronic device with which arrangement or direction optimal communication quality is provided can be calculated from rough layout information. For example, since the user provides layout information of a room to the server 750, an arrangement of an electronic device which arrangement is optimal to the layout can be transmitted from the server 750 to the information processing apparatus 100. Accordingly, the user can recognize an optimal arrangement of an electronic device before arranging the electronic device.
In such a manner, it is possible to learn arrangement information optimal to a system by using a cloud service.
Also, for example, when a user provides each piece of information (layout information or communication quality information), an incentive such as a discount for purchasing an additional electronic device or a point can be provided in return by a service. Also, performance of wireless varies depending on a device (difference in model or the like), and thus, information thereof can be also provided to the user. Accordingly, the service side can collect a data source. Also, the user can receive an incentive such as a discount or a point.
I such a manner, in an embodiment of the present technology, communication quality related to the electronic devices 200 to 204 (or also related to information processing apparatus 100 or 500) is reported to the information processing apparatus 100 or 500. Accordingly, the information processing apparatus 100 or 500 can display the communication quality related to the electronic devices 200 to 204 in real time in a manner easily recognized by a user. Also, when the user checks the display contents, each of the electronic devices 200 to 204 can be arranged at a place optimal as a system appropriate for an environment.
Accordingly, an arrangement including a direction optimal to each of the electronic devices 200 to 204 can be set by the user freely. That is, an environment appropriate for communication quality between the electronic devices 200 to 204 can be provided.
Also, in a case of newly adding an electronic device to the communication system 10, a user can easily recognize a place and the number of electronic devices to be added to improve system performance of a mesh network. Also, in a case of reducing an electronic device from the mesh network or replacing an electronic device included in the mesh network, a user can easily come to recognition in a similar manner.
Also, an installation place of each of the electronic devices 200 to 204 can be changed at timing intended by the user.
Also, by accumulating and analyzing data in various environments, communication quality related to an electronic device can be learned and a user can be user induced to an optimal installation place.
