This application is based on and claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2019-0134931, filed on Oct. 28, 2019, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety.
The disclosure relates generally to an electronic device capable of sharing a peripheral device with an external electronic device and a method thereof, and more particularly, to a technology for allowing an external electronic device to use a peripheral device connected with an electronic device as a peripheral device of the external electronic device.
Technologies for performing wireless communication between a plurality of devices by using various kinds of short-range communication are being developed and used. Bluetooth™ low energy (BLE) communication, being one of short-range wireless communication schemes, may transmit/receive data with a low power and thus may operate a device performing the BLE communication for a long time even with a low capacity battery.
Wi-Fi Aware™ is another wireless communication technology. Wi-Fi Aware™ may be used for beacon communication in which a short message is repeatedly sent.
It may be possible to use a peripheral device of an electronic device through a wireless connection using the short-range wireless communication. For example, it may be possible to use a peripheral device, such as a wireless keyboard, a wireless mouse, or an electronic pen, as an input device through a wireless connection with an electronic device.
In the case of connecting and using a peripheral device, which is connected with an electronic device through the short-range wireless communication, with another electronic device, a process of releasing the short-range wireless communication connection between the peripheral device and the electronic device and again performing the short-range wireless communication connection with a different electronic device may be required. Also, the same operation may be repeated again to connect the peripheral device with the electronic device after the peripheral device is connected with the other electronic device.
In this case, because a user of the electronic device may have to perform repetitive operations to change a device connected with the peripheral device of the electronic device through the short-range wireless communication, a user of the electronic device may be inconvenienced. Thus, a device and method for allowing any other device to easily use the peripheral device connected with the electronic device would be advantageous.
The present disclosure has been made to address the above-mentioned problems and disadvantages, and to provide at least the advantages described below.

In accordance with another aspect of the disclosure, a method in which an electronic device shares a peripheral device may include performing first short-range wireless communication based on a first protocol with the peripheral device, sensing an occurrence of a trigger event, transmitting a service discovery frame including service information associated with the peripheral device to devices included in a cluster configured to include the electronic device through second short-range wireless communication, in response to the trigger event, establishing a wireless data communication path with an external electronic device, which transmits a message in response to the service discovery frame to the electronic device through the second short-range wireless communication, from among the devices included in the cluster, and transmitting input information received from the peripheral device or control information corresponding to the input information to the external electronic device through the wireless data communication path.
In accordance with another aspect of the disclosure, an electronic device may include a short-range wireless communication circuit that performs first short-range wireless communication based on a first protocol and second short-range wireless communication based on a second protocol, and a processor that is connected with the short-range wireless communication circuit, and the processor may receive an advertising packet from an external electronic device through the first short-range wireless communication, may determine whether the advertising packet includes a communication service identifier identifying a communication service performed based on the second short-range wireless communication, may enable a function of the communication service when the advertising packet includes the communication service identifier, may form a cluster with the external electronic device based on the second short-range wireless communication, may establish a wireless data communication path with the external electronic device, may receive input information that was received from a peripheral device communicatively connected with the external electronic device from the external electronic device through the wireless data communication path or control information corresponding to the input information, and may execute instructions corresponding to the received input information or the control information.

The resonant circuit 287 may resonate based on an electromagnetic signal generated from a digitizer (e.g., the display device 160) of the electronic device 101 and may radiate an electro-magnetic resonance (EMR) input signal (or a magnetic field) by the resonance. The electronic device 101 may verify a location of the stylus pen 201 on the electronic device 101 by using the EMR input signal. For example, the electronic device 101 may verify a location of the stylus pen 201, based on a magnitude of an induced electromotive force (e.g., an output current) generated by the EMR input signal at each of a plurality of channels (e.g., a plurality of loop coils) in the digitizer.
The description given above is for the electronic device 101 and the stylus pen 201 operating based on an EMR scheme, but this is only an example. The electronic device 101 may generate an electric field-based signal by using an electrically coupled resonance (ECR) scheme.

The resonant circuit 287 may resonate based on an input electric field and/or an input magnetic field (e.g., an electric field and/or a magnetic field generated from the digitizer of the electronic device 101). In the case where the stylus pen 201 transmits a signal in the EMR scheme, the stylus pen 201 may generate a signal including a resonant frequency, based on an electromagnetic field generated from an inductive panel of the electronic device 101. In the case where the stylus pen 201 transmits a signal in the AES scheme, the stylus pen 201 may generate a signal by using the capacity coupling with the electronic device 101. In the case where the stylus pen 201 transmits a signal in the ECR scheme, the stylus pen 201 may generate a signal including a resonant frequency, based on an electric field generated from a capacitive device of the electronic device 101. The resonant circuit 287 may be used to change the intensity or a frequency of an electromagnetic field depending on a manipulating state of the user. For example, the resonant circuit 287 may provide various frequencies for recognizing a hovering input, a drawing input, a button input, or an erasing input. For example, the resonant circuit 287 may provide various resonant frequencies depending on a connection combination of a plurality of capacitors or may provide various resonant frequencies based on a variable inductor and/or a variable capacitor.

The stylus pen 201 may determine whether the stylus pen 201 is inserted into the electronic device 101, by using a voltage level of the direct current signal detected from the charging circuit 288. Alternatively, the stylus pen 201 may verify a pattern corresponding to a signal checked by the charging circuit 288 to determine whether the stylus pen 201 is inserted into the electronic device 101.
The battery 289 may store a power necessary for an operation of the stylus pen 201.

The communication circuit 290 may transmit state information of the stylus pen 201, input information of the stylus pen 201, and/or information associated with a location of the stylus pen 201 to the electronic device 101 by using a short-range communication scheme.

At least a part of functions of the pen controller 410 may be performed by the processor 120, or the pen controller 410 and the processor 120 may be integrally implemented. Alternatively, the pen controller 410 may be integrally implemented with a sensing panel controller to be described later.
The expression “the pen controller 410 performs a specific operation” may mean that the specific operation is performed by the processor 120 or is performed by a control circuit independent of the processor 120. The pen controller 410 may include a control circuit (e.g., a control circuit independent of the processor 120), an inverter, and/or an amplifier, in addition to the at least one coil 411 or 412. As described above, the pen controller 410 may not include the control circuit; in this case, the pen controller 410 may provide a charging signal to the at least one coil 411 or 412 under the control of the processor 120.
The pen controller 410 may provide a signal having a pattern through the at least one coil 411 or 412. The pattern may be in advance shared with the stylus pen 201 for a control of the stylus pen 201 and may include, for example, a charging start indicating pattern, a charging end indicating pattern, or a detection pattern. However, there is no limitation on a kind of the pattern. The at least one coil 411 and 412 for providing the charging signal or the signal having the control pattern are illustrated, but this is only one example. There is no limitation on the number of coils.
A resonant circuit 420 of the stylus pen 201 may include the coil 421, at least one capacitor 422 or 423, and/or a switch 424. When the switch 424 is in an OFF state, the coil 421 and the capacitor 422 may constitute a resonant circuit; when the switch 424 is in an ON state, the coil 421 and the capacitors 422 and 423 may constitute a resonant circuit. That is, as the switch 424 is turned on/off, a resonant frequency of the resonant circuit 420 may be changed. For example, the electronic device 101 may verify an ON/OFF state of the switch 424, based on a frequency of a signal from the stylus pen 201. In addition, when the button 337 of the stylus pen 201 is pressed/released, the switch 424 may be turned on/off, and the electronic device 101 may determine whether the button 337 of the stylus pen 201 is pressed, based on a frequency of a signal received through the digitizer.
At least one rectifier 431 or 435 may rectify and output a signal VPEN of an alternating current (AC) waveform output from the resonant circuit 420. A charging switch controller (SWchg ctrl) 432 may receive a rectified signal VM output from the rectifier 431. Based on the rectified signal VM, the charging switch controller 432 may determine whether a signal generated by the resonant circuit 420 is a signal for charging or a signal for location detection. For example, the charging switch controller 432 may determine whether the signal generated by the resonant circuit 420 is the signal for charging or the signal for location detection, based on a magnitude of a voltage of the rectified signal VM. Alternatively, the charging switch controller 432 may determine whether a signal having a pattern for charging start is input, based on a waveform of the rectified signal VM.
When it is determined that the signal is the signal for charging, the charging switch controller 432 may control a charging switch (SWchg) 436 to an ON state. Alternatively, when the signal having the pattern for charging start is detected, the charging switch controller 432 may control the charging switch 436 to an ON state. The charging switch controller 432 may transfer a charging start signal chg_on to the charging switch 436. In this case, a rectified signal voltage input (VIN) may be transferred to a battery 437 through the charging switch 436. The battery 437 may be charged by using the rectified signal VIN thus received. An over-voltage protection circuit (OVP) 433 may verify a battery voltage (VBAT) and may control the charging switch 436 to an OFF state when the battery voltage VBAT exceeds an over-voltage threshold value.
When it is determined that the battery voltage VBAT exceeds an operating voltage threshold value, a load switch controller (SWL ctrl) 434 may control a load switch (SWL) 438 to an ON state. When the load switch 438 is turned on, power from the battery 437 may be transferred to a BLE communication circuit and controller (BLE+controller) 439. The BLE communication circuit and controller 439 may operate using the received power. When a distance between the stylus pen 201 and the electronic device 101 is greater than a threshold distance, a button control circuit (a button control) 440 may transfer information about an input of a button 337 to the BLE communication circuit and controller 439. The BLE communication circuit and controller 439 may transmit the received information about the button input to the electronic device 101 through an antenna 441. A sensor 450 may include a gyro sensor 451 and an accelerometer 452. The gyro sensor 451 and/or the accelerometer 452 may transfer sensing data obtained by the accelerometer 452 to the BLE communication circuit and controller 439. The BLE communication circuit and controller 439 may transmit a communication signal including the received sensing data to the electronic device 101 through the antenna 441. Alternatively, the BLE communication circuit and controller 439 may verify information (e.g., coordinates and/or displacement of the stylus pen 201) associated with a location of the stylus pen 201 determined based on the received sensing data. The BLE communication circuit and controller 439 may transmit the verified information associated with the location of the stylus pen 201 to the electronic device 101 through the antenna 441. When the stylus pen 201 is pulled out from the electronic device 101, the BLE communication circuit and controller 439 may activate the accelerometer 452. When the button 337 is pressed, the BLE communication circuit and controller 439 may activate the gyro sensor 451. There is no limitation on an activation time for each sensor. In addition, the sensor 450 may further include a geomagnetic sensor. When only the accelerometer 452 is activated, the stylus pen 201 may provide information of an acceleration measured by the accelerometer 452 to the electronic device 101, and the electronic device 101 may operate based on both the acceleration information and the location of the stylus pen 201 verified based on a pen signal.

Alternatively, the processor 120 may verify a location of the stylus pen 201 based on magnitudes of signals respectively output from the loop coils (e.g., digital values converted for respective channels). For example, the sensing panel 503 may apply a current to at least one of the loop coils, and the at least one coil may form a magnetic field. The stylus pen 201 may resonate by the magnetic field formed around the stylus pen 201, and a magnetic field may be formed from the stylus pen 201 by the resonance. A current may be output from each of the loop coils by the magnetic field formed from the stylus pen 201. The electronic device 101 may verify a location of the stylus pen 201 based on magnitudes of currents for respective channels of the loop coils (e.g., converted digital values). To determine a location of the stylus pen 201, the loop coils may include coils extended in one axis direction (e.g., an x-axis direction) and coils extended in another axis direction (e.g., a y-axis direction), but there is no limitation on a way to arrange the stylus pen 201 with respect to the loop coils.
The sensing panel controller 511 may apply a transmit signal TX to at least a part of the plurality of loop coils of the sensing panel 503, and a loop coil receiving the transmit signal TX may form a magnetic field. The sensing panel controller 511 may receive a receive signal RX output from at least a part of the plurality of loop coils in a time division manner. The sensing panel controller 511 may verify a location of the stylus pen 201 based on the receive signal RX and may transfer information about the location of the stylus pen 201 to the processor 512. For example, magnitudes of the receive signals RX of the respective loop coils (e.g., respective channels) may be different, and a location of the stylus pen 201 may be verified based on the magnitudes of the receive signals RX. In addition, the electronic device 101 may determine whether the button 337 of the stylus pen 201 is pressed, based on a frequency of a receive signal RX. For example, when the frequency of the receive signal RX is a first frequency, the electronic device 101 may determine that the button of the stylus pen 201 is in a state of being pressed; when the frequency of the receive signal RX is a second frequency, the electronic device 101 may determine that the button of the stylus pen 201 is in a state of being released. Alternatively, in the case where the sensing panel 503 is implemented with a touch sensing panel (TSP), the sensing panel 503 may verify a location of the stylus pen 201 based on an output signal from an electrode. Alternatively, the electronic device 101 may detect the stylus pen 201 based on a change in a capacitance (e.g., a mutual capacitance or a self-capacitance) at an electrode of the sensing panel 503. Hardware, which is capable of sensing a pen signal from the stylus pen 201, such as the digitizer or the touch sensing panel may be referred as to as the “sensing panel 503”. In the case of verifying a location of the stylus pen 201 by using the touch sensing panel, the electronic device 101 may determine whether the button is pressed, based on a received communication signal. The electronic device 101 may detect the stylus pen 201 (or a location of the stylus pen 201) by recognizing a static electricity based on an AES scheme.
The sensing panel controller 511 may determine whether the stylus pen 201 is inserted into (or coupled or attached to) the electronic device 101, based on a receive signal RX and may transfer a result of the determination to the processor 512. The sensing panel controller 511 may be integrally implemented with the sensing panel 503. The processor 512 may transmit a signal for wireless charging, based on whether the stylus pen 201 is inserted into the electronic device 101. The processor 512 may control the Bluetooth controller 513 based on whether the stylus pen 201 is inserted into the electronic device 101. When a wireless communication connection is not formed, the processor 512 may control the Bluetooth controller 513 such that wireless communication with the stylus pen 201 is connected. In addition, the processor 512 may transmit charging level information to the electronic device 101 when the stylus pen 201 is mounted therein and may transmit information about a button press and information about sensing data to the electronic device 101 when the stylus pen 201 is detached therefrom. In addition, the processor 512 may allow a charging signal and a control signal to be transmitted to the sensing panel controller 511, based on data received from the stylus pen 201. The processor 512 may verify a gesture of the stylus pen 201 based on the data received from the stylus pen 201 and may perform an operation corresponding to the gesture. The processor 512 may transfer a function mapped on the gesture to an application. The Bluetooth controller 513 may exchange information with the stylus pen 201 through the antenna 514. The display assembly 502 may include a component for displaying a screen. The window 501 may be formed of a transparent material such that at least a portion of the display assembly 502 is visually exposed.

At least a portion of information that is used to form the short-range wireless communication connection may be stored in the electronic device 600 and the peripheral device 605 in the process of manufacturing the electronic device 600 and the peripheral device 605. For example, the electronic device 600 and the peripheral device 605 may store key information (e.g., a long term key) and device information generated through a pairing process based on the BLE communication protocol. In the case where short-range wireless communication between the electronic device 600 and the peripheral device 605 is connected, without an additional pairing process, it may be possible to encrypt a channel for short-range wireless communication through the key information stored in the manufacturing process and to transmit data through the encrypted channel.
In the case where the peripheral device 605 is coupled to the first inner space 212 of the electronic device 600 in a state where device information and key information about the peripheral device 605 are not stored in the electronic device 600, the peripheral device 605 may transmit the advertising packet that the electronic device 600 is able to recognize, and the electronic device 600 may receive the advertising packet and may then connect short-range wireless communication through a connection request. Afterwards, the electronic device 600 and the peripheral device 605 may generate key information through the pairing process, may encrypt the channel for short-range wireless communication by using the generated key information, and may transmit data through the encrypted channel.
In a state where the short-range wireless communication 600 is connected, input information that the peripheral device 605 obtains may be transmitted to the electronic device 600 through the short-range wireless communication 610. For example, the electronic device 600 may use the peripheral device 605 as an input device. Additionally or alternatively, the peripheral device 605 may be a different type of device, not an electronic pen, and the electronic device 600 may use the peripheral device 605 as an output device or a data storage device.
The electronic device 600 may form a cluster 630 with the external electronic device 620 placed around the electronic device 600. The cluster 630 may mean a set of devices exchanging signals periodically or frequently. To form the cluster 630, the electronic device 600 and the external electronic device 620 may transmit or receive a signal by using a short-range wireless communication scheme. In
The electronic device 600 may broadcast the advertising packet based on a first communication scheme. For example, the electronic device 600 may transmit a BLE advertising signal based on the BLE communication scheme. A time when the BLE advertising signal is transmitted may be variously implemented depending on the embodiment. For example, the electronic device 600 may broadcast the BLE advertising signal periodically. Alternatively, when a specified condition is satisfied, the electronic device 600 may broadcast the BLE advertising signal. The advertising packet may include a communication service identifier for identifying a communication service that is performed based on a second communication scheme. For example, the advertising packet may include a Wi-Fi Aware service identification (ID) for enabling a Wi-Fi Aware function. The external electronic device 620 receiving the advertising packet may enable the Wi-Fi Aware function corresponding to the Wi-Fi Aware service ID to form the cluster 630 with the electronic device 600. Also, when the electronic device 600 receives the advertising packet, the electronic device 600 may enable the Wi-Fi Aware function. For example, when one or more external electronic devices exist in the vicinity of the electronic device 600 and a cluster to which the respective devices belong does not exist, the electronic device 600 may form a cluster with one or more external electronic devices within a specified range to generate a common wake/sleep heartbeat. Additionally or alternatively, when a cluster to which an external electronic device belongs exists around the electronic device 600, the electronic device 600 may join the cluster; or when the electronic device 600 belongs to a first cluster and an external electronic device placed around the electronic device 600 belongs to a second cluster, the electronic device 600 and the external electronic device may perform a merge process for merging the first cluster and the second cluster. The merge process may mean to set communication such that devices included in the first cluster and devices included in the second cluster are synchronized and find a service with any other device without continuous data transmission/reception.
The electronic device 600 may select the external electronic device 620, which will share a function of the peripheral device 605, from among devices included in the cluster 630. The electronic device 600 may establish a wireless data communication path 640 with the selected external electronic device 620. The wireless data communication path 640 may be a communication path configured to transmit or receive data between two electronic devices by using a Wi-Fi communication scheme or a Bluetooth™ communication scheme. For example, the electronic device 600 may transmit a service search protocol message for searching for a service associated with the function of the peripheral device 605 to be shared, to one or more other devices (e.g., the external electronic device 620) in a cluster. The expression “transmitting the service search protocol message” may mean that the electronic device 600 publishes a message.
The external electronic device 620 receiving the message may find a service by using the message and may transmit, to the electronic device 600, information about whether the service is available. For example, the external electronic device 620 may transmit, to the electronic device 600, a subscribe message indicating that a corresponding device has to transmit a publish message when a specific condition is satisfied. The electronic device 600 may select the external electronic device 620 capable of providing a service associated with the function of the peripheral device 605. The electronic device 600 may transmit input information received from the peripheral device 605 to the external electronic device 620 through the wireless data communication path 640 and may allow the external electronic device 620 to operate as if the external electronic device 620 connects to the peripheral device 605 and uses the peripheral device 605 as an input device. The electronic device 600 may receive input information from the peripheral device 605 and may transmit the received input information to the external electronic device 620. In detail, the input information may include gesture information, pressure information, location information, biometric information, or temperature information input by using a sensor 299 of the peripheral device 605 or an input value through a press of a button 337. In response to the gesture information, the external electronic device 620 may execute instructions that cause a camera application of the external electronic device 620 to photograph an image by using a camera of the external electronic device 620.
The electronic device 600 may search a memory 130 of the electronic device 600 for a control command corresponding to the input information received from the peripheral device 605. The electronic device 600 may transmit the found control command to the external electronic device 620 such that the external electronic device 620 executes the control command.
The external electronic device 720 may include various types of devices capable of providing a service that performs communication with the electronic device 700 and uses the peripheral device 705.

When the location of the cursor 725 is out of the screen of the external electronic device 720 by the input information received from the peripheral device 705, the cursor 725 may be displayed at any other device.
When an input (e.g., a specific key input or an input through a button (e.g., the button part 323 of
In step 810, the electronic device determines (or monitors) whether a trigger event occurs. The trigger event means an event that causes the electronic device to enable a wireless communication function (e.g., a Wi-Fi Aware function) for communicating with an external electronic device. For example, the trigger event may include a signal of sensing that a peripheral device is detached from a coupling structure of the electronic device. In another example, the trigger event may include a user input that is received by using a user interface displayed on a display device of the electronic device and indicates an enable function of the wireless communication. In yet another example, the trigger event may include receiving an advertising packet including a service ID corresponding to the wireless communication function.
However, the disclosure is not limited thereto and the trigger event may be variously implemented depending on embodiments. For example, when a user input is received for selecting a menu for executing a peripheral device sharing function displayed at the electronic device, the electronic device may determine that the trigger event occurs. Alternatively, when a share camera application allowing the electronic device to share a camera function with the external electronic device is executed, the electronic device may determine that the trigger event occurs. In yet another example, the electronic device may obtain location information of the electronic device (e.g., may obtain a global positioning system (GPS) coordinate value); when the location information of the electronic device indicates that the electronic device is present in a specified region (e.g., a photo zone of a tourist spot), the electronic device may determine that the trigger event occurs. Alternatively, the trigger event may occur at the peripheral device or the external electronic device. For example, when information about a button input of the peripheral device is transferred to the electronic device, the electronic device may determine that the trigger event occurs. Alternatively, in yet another example, when a request for sharing the peripheral device is received from the external electronic device, the electronic device may determine that the trigger event occurs.
When it is determined that the trigger event occurs, in step 820, the electronic device establishes a wireless data communication path with the external electronic device. In step 820, when a communication function (e.g., a Wi-Fi Aware function) for performing wireless data communication with the external electronic device is in a disable state, the electronic device may enable the communication function. Also, the electronic device may allow the external electronic device placed around the electronic device to enable the communication function (e.g., a Wi-Fi Aware function). The electronic device may form a cluster including the external electronic device based on the enabled communication function. The electronic device may select the external electronic device included in the cluster and may establish a wireless data communication path (e.g., a neighborhood area network (NAN) data path) for transmitting data to the external electronic device.
In step 830, the electronic device transmits input information (or control information) received from the peripheral device through short-range wireless communication to the external electronic device through the wireless data communication path. For example, the electronic device may transmit gesture information received from an electronic pen through BLE communication to the external electronic device through a Wi-Fi communication connection. In the case where the NAN data path (or channel) is formed with the external electronic device, the electronic device may transfer the input information received from the peripheral device through the NAN data path to the external electronic device.
The electronic device may transmit control information corresponding to the input information received from the peripheral device to the external electronic device. The electronic device may receive gesture information from the electronic pen and may determine characteristic information, which corresponds to characteristic information extracted from the received gesture information, from among data stored in the electronic device. In the case where the control information stored in association with the determined characteristic information relates to instructions causing a camera to photograph an image, the electronic device may transmit the control information for image photographing to the external electronic device. Additionally or alternatively, as a button input of the electronic pen is received, the electronic device may transmit an application switch command to the external electronic device or may transmit control information corresponding to an input value to the external electronic device.
In step 911, the electronic device 901 connects short-range wireless communication with the peripheral device 902. For example, when the electronic device 901 senses a state where the peripheral device 902 is connected to a coupling structure of the electronic device 901, the electronic device 901 may obtain identification information of the peripheral device 902 connected with the electronic device 901 and may connect the short-range wireless communication with the peripheral device 902 based on a Bluetooth communication scheme. The electronic device 901 may receive input information from the peripheral device 902 through the short-range wireless communication. For example, when the stylus pen 201 is inserted into the inner space 212 of the electronic device 101, the electronic device 101 may connect the short-range wireless communication for receiving input information from the stylus pen 201.
In step 913, the electronic device 901 determines whether the trigger event occurs. When it is determined that the trigger event occurs, in step 915, the electronic device 901 broadcasts the advertising packet including a service ID (e.g., a Wi-Fi Aware service ID) used to identify a service for performing communication with the external electronic device 903. The electronic device 901 may transmit the advertising packet based on the BLE communication standard. Also, the electronic device 901 may enable a communication function (e.g., Wi-Fi Aware) for performing communication with the external electronic device 903.
In step 917, the external electronic device 903 receives the advertising packet and verifies the service ID included in the advertising packet. The external electronic device 903 may perform a BLE scan and may receive the advertising packet that the electronic device 901 transmits, as a result of the BLE scan. The external electronic device 903 may be connected to an access point where the electronic device 901 is connected and may receive the advertising packet through the access point. Alternatively, in the case where the electronic device 901 and the external electronic device 903 log in to a server by using the same user account, the external electronic device 903 may receive the advertising packet through the server. In the case where the service ID is included in the advertising packet, the external electronic device 903 may enable a communication function (e.g., Wi-Fi Aware) corresponding to the service ID.
When the communication functions of the external electronic device 903 and the electronic device 901 placed within a short range from each other are enabled, a cluster including the electronic device 901 and the external electronic device 903 may be formed. The electronic device 901 and the external electronic device 903 may periodically transmit a sync beacon packet (e.g., a NAN sync beacon) for the purpose of forming the cluster, and the cluster including the electronic device 901 and the external electronic device 903 may be formed.
In step 921, the electronic device 901 selects the external electronic device 903 that will share an input of the peripheral device 902 within the cluster to which the electronic device 901 belongs. An operation in which the electronic device 901 selects the external electronic device 903 may be variously implemented. For example, the electronic device 901 may output a device list including devices included in a cluster as candidate devices and may receive a user input of selecting the external electronic device 903 in the output device list. Alternatively, the electronic device 901 may transmit information requesting to receive an input of the peripheral device 902 to the devices included in the cluster and may select a device responding to the request.
When a given condition is satisfied, the electronic device 901 may automatically select the external electronic device 903 without a user input. For example, in the case where the external electronic device 903 is a device whose account is identical to an account of the electronic device 901 or is a device having a family account of the electronic device 901, the electronic device 901 may select the external electronic device 903. In this case, the electronic device 901 may output information associated with the external electronic device 903 connected thereto, for example, a message providing notification that the peripheral device 902 is shared by the external electronic device 903.
In step 923, the electronic device 901 establishes a wireless data communication path with the external electronic device 903 thus selected. For example, the electronic device 901 may establish a Wi-Fi communication connection with the external electronic device 903. Additionally, among the devices included in the cluster, each of the electronic device 901 and the external electronic device 903 may disable a specified communication function (e.g., a Wi-Fi Aware function) or may stop an operation during a specified time period.
In step 925, the peripheral device 902 obtains input information. For example, the peripheral device 902 may obtain movement information corresponding to a physical movement of the peripheral device 902 sensed through a sensor (e.g., an accelerometer or a gyro sensor) included in the peripheral device 902. The input information may include a button input or pressure information of a pen.
In step 927, the peripheral device 902 transmits the obtained input information to the electronic device 901 through the short-range wireless communication connected in operation 911.
In step 929, the electronic device 901 transmits the input information received from the peripheral device 902 or control information corresponding to the input information to the external electronic device 903 through the wireless data communication path established in step 923. For example, when the received input information includes gesture information for performing a specified function of the external electronic device 903, the electronic device 901 may transmit control information for performing the specified function of the external electronic device 903 to the external electronic device 903. The external electronic device 903 receiving the input information or the control information may execute instructions corresponding to the input information or the control information.
In the case where the wireless data communication path between the external electronic device 903 and the electronic device 901 is not established, in step 929, a processor 120 of the electronic device 901 executes instructions that correspond to the received input information and are stored in the memory 130. For example, in the case where the received input information includes specified gesture information, the electronic device 901 may execute an operation of photographing an image by using a camera application executed by the electronic device 901.
The electronic device 901 may select a device that will process the input information or the control information. For example, the electronic device 901 or the external electronic device 903 may be selected based on a user input received through a user interface that the electronic device 901 displays, or the electronic device 901 and the external electronic device 903 may be selected as operating together. In step 929, the electronic device 901 determines whether to transmit the input information or the control information to the external electronic device 903.

For example, when a user input of selecting a share function end button provided at the electronic device is received, when a location of the electronic device is out of a specified region, when control information of a specified unit is completely transmitted, or when a specified time period passes, the electronic device may end a function for sharing the peripheral device.

The version information 1324, the service ID 1325, and the service specific data 1326 that are data capable of being specified by a manufacturer may be referred to as “manufacturer specific data”. For example, the electronic device may define a Wi-Fi Aware service ID at the service ID 1325 and may include information required for a Wi-Fi Aware service in the service ID 1325. The electronic device receiving the advertising packet may verify company ID 1323, version information 1324, service ID 1325, or service specific data 1326 and may identify that a device transmitting the advertising packet is a device supporting the Wi-Fi Aware service.
In step 1410, the electronic device publishes a service discovery frame (e.g., a NAN discovery frame) to devices included in a cluster. The expression “publish” the service discovery frame may be understood to mean “transmitting” the service discovery frame. The service discovery frame may include a service name (e.g., a Bluetooth™ share service) of a service providing a function for a peripheral device and matching filter information.
In step 1420, the electronic device determines at least one candidate device subscribing the service discovery frame. For example, when the external electronic device receives the service discovery frame, the external electronic device may verify the service name and the matching filter information included in the service discovery frame. When the service name and the matching filter information are matched with information stored in the external electronic device, the external electronic device may transmit an acknowledgment (ACK) signal for the received service discovery frame. The electronic device may receive the ACK signal and may determine the external electronic device transmitting the ACK signal as a device subscribing the service discovery frame.
In step 1425, the electronic device certifies at least one candidate device. For example, in the case where contact information associated with the at least one candidate device is stored in the electronic device, the electronic device may certify the candidate device. However, step 1425 may also not be executed. For example, in the case where location information of the electronic device indicates that the user is at home, the electronic device may not perform certification on devices placed around the electronic device.
In step 1430, the electronic device displays a device list for the at least one device. In the case where the at least one candidate device is certified in step 1425, the electronic device may display the device list including only a device that is completely certified in step 1430.
In step 1440, the electronic device receives a user input of selecting the external electronic device from candidate devices included in the device list. In step 1450, the electronic device establishes the wireless data communication path with the external electronic device thus selected.
Referring to
Also, the electronic device 1500 may display a screen including a device list 1510 including at least one candidate device. The electronic device 1500 may receive a user input (e.g., a touch input through a touch screen) for selecting an external electronic device from devices included in the device list 1510.
Based on the user input, the electronic device 1500 may select only one of the devices included in the device list 1510 or may select a plurality of devices thereof. In this case, the electronic device 1500 may display check boxes on one side (e.g., the left or right) of the device list 1510. The electronic device 1500 may select devices as much as the number of check boxes selected from among the check boxes.
In the case where a plurality of devices (e.g., “Hank Phone” and “My phone”) are selected, the plurality of devices may be simultaneously controlled by the peripheral device. For example, based on a user input received through the peripheral device, the plurality of devices may simultaneously photograph images, may photograph images at a specified time interval, or may perform continuous photographing in turn.
In step 1611, the electronic device 1601 generates a first hash value for transferring identification information of the electronic device 1601. The identification information of the electronic device 1601 may mean information for identifying an electronic device. For example, the identification information may include contact information, user account information, a user name, a user nick name, a group to which a user belongs, or a social media ID, which is associated with the electronic device 1601.
In step 1613, the electronic device 1601 transmits a first message including the first hash value to the external electronic device 1603. The external electronic device 1603 may decode the first hash value of the received message. In step 1615, the external electronic device 1603 determines whether data obtained by decoding the first message is included in a contact database of the external electronic device 1603. The contact database may be a database that is implemented with contact information registered by the user.
When the data obtained by decoding the first message is included in the contact database of the external electronic device 1603, in step 1617, the external electronic device 1603 generates a second hash value of the identification information of the external electronic device 1603. In step 1619, the external electronic device 1603 transmits a second message including the second hash value to the electronic device 1601.
The electronic device 1601 receiving the second message may decode the second hash value of the received message. In step 1621, the electronic device 1601 determines whether data obtained by decoding the second message is included in the contact database of the electronic device 1601.
When the data obtained by decoding the second message is included in the contact database of the electronic device 1601, in step 1623, the electronic device 1601 displays a device list including information about the external electronic device 1603. The information about the external electronic device 1603 may include identification information about the external electronic device 1603. When the external electronic device 1603 is selected from the device list, in step 1625, the electronic device 1601 establishes a wireless data communication path with the external electronic device 1603.
The steps illustrated in the flowchart 1700 of
In step 1711, the external electronic device 903 executes an application for providing a service associated with the peripheral device 902. For example, the external electronic device 903 may execute a camera application capable of receiving an image photographing command by using the peripheral device 902. In another example, the external electronic device 903 may execute an application capable of providing an air mouse function by using an input received through the peripheral device 902. However, step 1711 may be replaced with any other operation indicating a context associated with an operation of the external electronic device 903. For example, step 1711 may be replaced with a step of changing an operation mode of the external electronic device 903 or a step in which the external electronic device 903 receives a specified user input through an input device of the external electronic device 903.
In step 1713, the external electronic device 903 transmits information about an operation state to the electronic device 901. For example, the external electronic device 903 may transmit, to the electronic device 901, information indicating that a current state is a state where the camera application is executed. In another example, the information about the operation state may be information about an operation mode set to the external electronic device 903. The electronic device 901 receiving the information about the operation state may store the received information about the operation state or may set a flag indicating the operation state of the external electronic device 903. In yet another example, the information about the operation state may be transferred by using the Wi-Fi Aware function.
In step 1715, the peripheral device 902 obtains input information. In step 1717, the peripheral device 902 transmits the obtained input information to the electronic device 901. In step 1719, the electronic device 901 transmits the input information or control information corresponding to the input information to the external electronic device 903 depending on the operation state of the external electronic device 903. For example, in the case where the external electronic device 903 is in a state of executing the camera application, the electronic device 901 may transmit the input information or the control information associated with camera photographing to the external electronic device 903. The external electronic device 903 may execute a function of an application based on the received control information. Additionally or alternatively, the external electronic device 903 may execute an operation of capturing an image by using a camera of the external electronic device 903 as a response to the control information, or may move a location of a cursor on a display as a response to the control information. The operation of the external electronic device 903, which is performed based on the control information, may be variously implemented depending on embodiments.
In step 1721, the external electronic device 903 ends the application providing the service associated with the peripheral device 902. The external electronic device 903 may transmit, to the electronic device 901, information about an operation state indicating that the application providing the service associated with the peripheral device 902 ends. After step 1723, the peripheral device 902 obtains input information in step 1725. In step 1727, the peripheral device 902 transmits the input information obtained in step 1725 to the electronic device 901. In step 1729, the electronic device 901 executes instructions that cause a function of the electronic device 901 to be performed without transmitting the input information received from the peripheral device 902 to the external electronic device 903. Additionally, when a function of sharing input information of the peripheral device 902 with the external electronic device 903 ends, the electronic device 901 may execute instructions that cause the function of the electronic device 901 to be performed without transmitting the input information to the external electronic device 903. For example, in the case where the communication is not made due to the disconnection of the wireless communication path between the electronic device 901 and the external electronic device 903, the electronic device 901 may execute instructions that cause the function of the electronic device 901 to be performed without transmitting the input information to the external electronic device 903.
In step 1810, the electronic device receives input information from the peripheral device through short-range wireless communication. In step 1820, the electronic device determines a category to which the received input information belongs. The category may mean a reference for classifying input information. For example, the electronic device may determine whether the input information is a command for controlling any service.
When the input information belongs to a first category, in step 1830, the electronic device transmits the input information or control information corresponding to the input information to the external electronic device through a wireless data communication path; when the input information belongs to a second category, in step 1840, the electronic device executes instructions for an operation corresponding to the input information or the control information without transmitting the input information or the control information. For example, assuming that the electronic device is a smartphone executing a camera application and the external electronic device is a television outputting an image, in the case where the input information is information belonging to a category permitting an image being output to be changed, the smartphone may transmit, to the television, control information that allows the television to change the displayed image. In contrast, in the case where the input information is information belonging to a category permitting an image to be photographed, the smartphone may perform an operation of photographing an image without transmitting the control information to the television.
In step 1910, an electronic device receives input information including movement information from the peripheral device. In step 1920, the electronic device extracts characteristic information from the received input information.
In step 1930, the electronic device determines gesture information matched with the characteristic information. For example, the electronic device may store characteristic information defining a plurality of characteristics and gesture information associated with each characteristic in a memory 130 of the electronic device. The electronic device may calculate the similarities between the characteristic information extracted from the input information and characteristics included in reference characteristic information to select a characteristic of the highest similarity. The electronic device may determine gesture information associated with the selected characteristic as gesture information matched with the characteristic information.
In step 1940, the electronic device determines an operation to be performed, based on the determined gesture information. When the determined gesture information is first gesture information, in step 1950, the electronic device transmits input information or control information corresponding to the input information to the external electronic device. When the determined gesture information is second gesture information, in step 1960, the electronic device executes an instruction corresponding to the input information. When the input information is gesture information of a vertical direction, the electronic device transmits the input information or the control information to the external electronic device so as to photograph an image. In contrast, when the input information is gesture information of a horizontal direction, the electronic device may execute instructions for switching a screen displayed at the electronic device.
The electronic device may determine an operation to be performed, based on a direction of the gesture information. For example, in the case where the gesture information indicates that a gesture starts from a location where the electronic device is placed, moves toward a location where the external electronic device is placed, and ends, the electronic device may transmit the control information to the external electronic device. In contrast, in the case where the gesture information indicates that a gesture moves toward a location where the electronic device is placed and then ends, the electronic device may perform a function corresponding to the input information received from the peripheral device. In another example, the electronic device may classify a gesture based on additional input information. In detail, the electronic device may determine first gesture information input in a state where a button 337 of the peripheral device is pressed and second gesture information input in a state where the button 337 is not pressed, as different gesture information. For example, the electronic device may transmit the control information to the external electronic device only with regard to information of a gesture performed in a state where the button 337 is pressed.
In step 2011, the electronic device senses that the electronic pen is detached from a coupling structure of the electronic device. When it is sensed that the electronic pen is detached, in step 2013, the electronic device transmits the advertising packet for allowing the external electronic device to enable a beacon communication function, to the surroundings of the electronic device.
In step 2015, the electronic device enables the beacon communication function (e.g., a Wi-Fi Aware function) for the purpose of performing communication with the external electronic device and forming a cluster. In step 2017, the electronic device forms the cluster including the external electronic device by using the beacon communication function.
In step 2019, the electronic device determines whether at least one external electronic device supports a service associated with input information of the electronic pen. For example, the electronic device may receive information including an identifier of the service, which the external electronic device supports, from the at least one external electronic device and may determine whether to support the service.
When it is determined that the at least one external electronic device supports the service associated with the input information of the electronic pen, in step 2021, the electronic device selects an external electronic device in the cluster. In step 2023, the electronic device establishes a wireless data communication path with the external electronic device thus selected.
In step 2025, the electronic device receives input information from the electronic pen. In step 2027, the electronic device transmits the input information received from the electronic pen or control information corresponding to the input information to the external electronic device.
The electronic device establishes the wireless data communication path with a plurality of external electronic devices in step 2023 and transmits the control information to the plurality of external electronic devices in step 2027. That is, the plurality of external electronic devices may be controlled based on input information received from one peripheral device. Also, the electronic device may transmit the control information to the external electronic device and may execute instructions corresponding to the input information. That is, the external electronic device and the electronic circuit may be controlled together based on a piece of input information.
In step 2029, the electronic device senses that the electronic pen is inserted into the electronic device. In step 2031, the electronic device disables the beacon communication function. Additionally, the electronic device may receive an input about disabling a pen share function through a user interface displayed at the electronic device and may disable the beacon communication function.
To receive the advertising packet transmitted by the electronic device, in step 2111, the external electronic device scans the advertising packet.
In step 2113, the external electronic device receives the advertising packet from the electronic device. In step 2115, the external electronic device determines whether a beacon communication service ID is included in the received advertising packet. When it is determined that the beacon communication service ID is not included in the received advertising packet, in step 2115, the external electronic device ignores the received advertising packet. When it is determined that the beacon communication service ID is included in the received advertising packet, in step 2117, the external electronic device enables a beacon communication function (e.g., a Wi-Fi Aware function). In step 2119, the external electronic device forms a cluster with surrounding devices in which the beacon communication function is enabled.
In step 2121, the external electronic device determines whether the electronic device transmitting the advertising packet supports a service associated with the electronic pen. When it is determined that the electronic device supports the service associated with the electronic pen, in step 2123, the external electronic device establishes a wireless data communication path between the electronic device and the external electronic device. When it is determined that the electronic device does not support the service associated with the electronic pen, in step 2131, the external electronic device disables the beacon communication function.
In step 2125, the external electronic device receives input information or control information from the electronic device through the wireless data communication path. In step 2127, the external electronic device executes instructions corresponding to the received input information or control information.
In step 2129, the electronic device or the external electronic device is released from the cluster. For example, a distance between the external electronic device and the electronic device may increase, or the electronic device may disable the beacon communication function. In step 2131, the external electronic device disables the beacon communication function.
