CROSS-REFERENCE TO RELATED APPLICATION(S)

[0001] This application is based on and claims priority under 35 U.S.C. .sctn. 119(a) of a Korean patent application number 10-2017-0109676, filed on Aug. 29, 2017, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety.

BACKGROUND

1.* Field*

[0002] The disclosure relates to methods for controlling the display of an electronic device using multiple controllers and devices.

2.* Description of Related Art*

[0003] There are being developed devices for providing their users with images using a virtual reality (VR) device. For example, a head-mounted display (HMD) is worn on the user to provide virtual reality images to the user. An HMD may be used together with, e.g., a mobile device. For example, an HMD may be connected with a mobile device, and the user who wears the HMD and moves her head may receive visual information about a VR space that the mobile device produces. The user may select or operate an object in the VR space by manually manipulating a controller (e.g., a hand controller) including a touchpad and home button.

[0004] In various applications utilizing various VR spaces, the user may control the display of the electronic device using one or more controllers (e.g., the HMD and the hand controller). For example, in a VR game using a pair of pistols, the user may wear the HMD, hold one hand controller in each hand, and manipulate the HMD and the two hand controllers to kill the enemies on the game screen that the display provides.

[0005] An electronic device providing VR space may point at a displayed object using the HMD or hand controller. The user wearing the HMD may point at any one object displayed on the screen that the HMD provides by moving her head or hand holding the hand controller.

[0006] The HMD pointing enables a control of the display by the user’s simple action, e.g., turning her head, thus eliminating the need for studying how to control. However, doing so for a long time may cause the user to feel tired or have difficulty in pointing at the exact position. The hand controller pointing requires the user to learn how to control, but despite its long-term use, the user would be less likely to suffer from fatigue and be able to achieve relatively precise pointing.

[0007] The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.

SUMMARY

[0008] Aspects of the disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. According, an aspect of the disclosure is to provide an apparatus and method for the electronic device to control the display using a plurality of controllers. For example, the plurality of controllers may include at least one or more of the head-mounted display (HMD) and the hand controller or may include a plurality of controllers of the same kind.

[0009] According to an embodiment of the disclosure, the electronic device may reflect the user’s intent to assign a right to control the display to at least one of the plurality of controllers and switch and re-assign the control right between the at least one controller corresponding to the user’s natural manipulation.

[0010] Additional aspects will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the presented embodiments.

[0013] In accordance with an aspect of the disclosure, a method for controlling, by an electronic device, a display using a plurality of controllers is provided. The method includes displaying a first pointer for a first controller based on first data obtained by a first sensor on a screen, receiving second data obtained by a second sensor of a second controller, and upon determining that the second controller points at the screen based on the second data, removing the first pointer from the screen and displaying a second pointer for the second controller based on the second data.

[0145] FIGS. 10, 11, and 12 are views illustrating an example in which an electronic device manipulates a display screen using a plurality of controllers according to various embodiments of the disclosure.

[0146] Referring to FIG. 10, the electronic device (e.g., the electronic device 200 of FIG. 2) may display a photo gallery including a plurality of photo data items 1001 to 1012 in the field of view and may point at a photo data item using the hand controller 1050. According to an embodiment of the disclosure, the electronic device 200 may point at each photo data item using the controller, selecting the corresponding photo data item. The electronic device 200 may enlarge the photo data item to allow the user to view the enlarged photo or may change the photo list displayed in the field of view. According to an embodiment of the disclosure, the electronic device 200 may control the operation of the display by an input device, such as the buttons of the controller, as well as manipulating the position pointed at by the controller. For example, the electronic device 200 may turn up the sound volume being played by pressing up the volume button of the hand controller or turn down the sound volume by pressing down the volume button. According to an embodiment of the disclosure, diversified numbers, types, or corresponding functions may be defined for the buttons of the controller in the electronic device 200. Referring to FIG. 3B, the hand controller 320 may include a plurality of buttons having various functions, such as a home button, a cancel button, trigger button, or sound volume button.

[0147] According to an embodiment of the disclosure, FIG. 10 illustrates an electronic device (e.g., the electronic device 200 of FIG. 2) in which where the user uses the HMD and the hand controller, the position 1060 pointed at by the hand controller is within the field of view. According to an embodiment of the disclosure, an object 1007 in the field of view may be pointed at depending on the position 1060 pointed at by the hand controller 1050 of the position 1040 pointed at by the HMD (not shown) and the position 1060 pointed at by the hand controller 1050. In this case, the electronic device 200 may use an input value for a button of the hand controller to execute a function predefined for the corresponding button. For example, the sound volume being played may be adjusted by pressing the volume button 1051 of the hand controller.

[0148] Referring to FIG. 11, where the user uses the HMD and the hand controller, the electronic device (e.g., the electronic device 200 of FIG. 2) may determine that the position 1070 pointed at by the hand controller falls outside the field of view 1001 and may point at an object in the field of view by the HMD. According to an embodiment of the disclosure, the electronic device 200 may manipulate the display using the buttons of the hand controller. According to an embodiment of the disclosure, the electronic device 200 may display messages for the buttons in the field of view to induce the user to use the buttons of the hand controller. Referring to FIG. 11, the electronic device 200 may display a message indicating that the volume button may shift the photo data item displayed up or down, and the channel button may shift the photo data item left or right. Where the position pointed at by the hand controller falls off the field of view while the user wears the HMD and uses the hand controller, the electronic device 200 may identify the function for the button displayed in the field of view and manipulate the button of the hand controller to control the operation of the display. For example, referring to FIG. 11, the electronic device 200 may control the operation of the display to shift from the photo data item currently selected to the photo data item thereabove by pressing the volume button 1051 of the hand controller 1050.

[0149] According to an embodiment of the disclosure, the electronic device 200 may set different definitions for the buttons of the hand controller depending on the features of the VR space provided to the user, leading the user to use the buttons. For example, the electronic device 200 may previously define a menu used for each game stage of a game application for each button of the hand controller in the VR space where the game application is being executed and may display the menu in the field of view, thereby allowing the user to perceive newly defined functions as well as the functions predefined for the buttons of the hand controller and to use the buttons.

[0150] Referring to FIG. 12, an example is illustrated in which an electronic device (e.g., the electronic device 200 of FIG. 2) manipulates a display screen using a plurality of controllers (e.g., the HMD 310 or hand controller 320 of FIG. 2), according to an embodiment of the disclosure. The plurality of controllers may include an HMD and a hand controller or several other controllers. According to an embodiment of the disclosure, the electronic device 200 may control the operation of the display using one HMD and two hand controllers.

[0151] According to an embodiment of the disclosure, where the user wears the HMD and holds the hand controllers in her hands, the electronic device 200 may point at an object displayed based on the HMD and the two hand controllers. For example, where the position pointed at by the left-hand controller and the position pointed at by the right-hand controller are in the field of view, the electronic device 200 may control the operation of the display using the left-hand controller and the right-hand controller, of the HMD, the left-hand controller, and the right-hand controller, but cannot point at an object in the field of view using the HMD.

[0152] Referring to FIG. 12, the electronic device 200 may select a menu icon using the hand controllers in the VR space where a video is played, select a volume menu 1221 for the video 1210 displayed in the field of view 1201 using the left-hand controller 1220, and select an execution menu 1231 using the right-hand controller 1230.

[0153] According to an embodiment of the disclosure, where the left-hand controller and the right-hand controller are used together, and the position pointed at by the left-hand controller is determined to fall outside the field of view, the electronic device 200 cannot control the operation of the display using the left-hand controller. As another example, upon determining that the position pointed at by the right-hand controller falls outside the field of view, the electronic device 200 cannot control the operation of the display using the right-hand controller. Where there are multiple hand controllers, the electronic device 200 may assign a control right to each hand controller depending on where the position pointed at by each hand controller is within the field of view. Where the positions pointed at by the two hand controllers fall outside the field of view, the electronic device 200 may point at an object in the field of view using the HMD. For example, where such a manipulation is possible as to plant and water a crop object without a game character entering and moving in a predetermined game space in a game execution screen, the electronic device 200 may display messages to exemplify the operation of planting crops corresponding to a first button and to exemplify the operation of watering the crops corresponding to a second button.

[0154] FIGS. 13A and 13B are views illustrating an example in which an electronic device identifies a right-hand controller or a left-hand controller according to an embodiment of the disclosure.

[0155] Referring to FIGS. 13A and 13B, an example is illustrated in which an electronic device (e.g., the electronic device 200 of FIG. 2) identifies a right-hand controller or a left-hand controller according to an embodiment of the disclosure. According to an embodiment of the disclosure, the electronic device 200 may control the operation of the display using two hand controllers. The electronic device 200 may provide the user with a guide message to identify the two hand controllers and may determine that a controller sensed is the one as per the guide message.

[0156] Referring to FIG. 13A, the electronic device 200 may control the display to display a guide message 1330 saying, “Hold the controller in your right hand,” in the field of view 1301. When the user holds a first controller 1310 in her right hand according to the guide message 1330 displayed on the display, the first controller 1310 may transmit data obtained by a sensor of the first controller 1310 to the electronic device 200. The electronic device 200 may identify the first controller 1310 based on the received sensor data and determine that the first controller 1310 is the right-hand controller.

[0157] FIG. 13B assumes the scenario in which the user holds the first controller 1310 in her hand while pointed at position 1311. According to an embodiment of the disclosure, the electronic device 200 may control the display to display a guide message 1340 saying, “Hold the controller in your left hand,” in the field of view 1301. When the user holds a second controller 1320 in her left hand according to the guide message displayed on the display, the second controller 1320 may transmit data obtained by a sensor of the second controller 1320 to the electronic device 200. The electronic device 200 may identify the second controller 1320 based on the received sensor data and determine that the identified second controller 1320 is the left-hand controller while pointed at position 1321.

[0158] According to an embodiment of the disclosure, where a plurality of users use their respective controllers to control a plurality of objects in the field of view, the electronic device 200 may allow the plurality of users to share the same VR space and may display a guide message to identify the controller corresponding to each user. The electronic device 200 may determine that a controller sensed after the guide message is displayed is the controller corresponding to the guide message. Where the plurality of users use the plurality of controllers, the electronic device 200 allows the user to clearly identify each controller by the process of identifying the plurality of controllers. According to an embodiment of the disclosure, various identification values may be defined and used for the plurality of controllers based, at least partially, on the interaction with the user, eliminating the need for setting the controllers to be operated as particular ones in the stage of manufacturing the controllers.

[0159] FIG. 14 is a view illustrating an example in which an electronic device selects an object simultaneously using two controllers according to an embodiment of the disclosure.

[0160] Referring to FIG. 14, the electronic device 200 selects an object using a first controller 1420 and a second controller 1430. According to an embodiment of the disclosure, the electronic device 200 may perform various types of control, such as selecting, deleting, or changing an object in the field of view, based on the distance between the positions pointed at by the two controllers. According to an embodiment of the disclosure, the electronic device 200 may point at a first object, among a plurality of objects in the field of view, using a first controller. The electronic device 200 may point at the first object at position 1410 using a second controller. According to an embodiment of the disclosure, in this case, corresponding to the first object being pointed at by the controller, the electronic device 200 may provide the user with a feedback indicating that the first object has been pointed at, such as highlighting and displaying the object.

[0161] According to an embodiment of the disclosure, where the distance between the position pointed at by the first controller and the position pointed at by the second controller is within a predetermined threshold, the electronic device 200 may associate the first controller with the second controller to control the operation of the display. Referring to FIG. 12, a field of view 1401 is displayed including objects 1401 to 1407. When the distance between the position 1410 pointed at by the first controller and the position 1421 pointed at by the second controller is within the predetermined threshold, and the object 1402 is simultaneously pointed at by the first controller 1420 and the second controller 1430, the electronic device 200 may “select” the object 1402 corresponding to the operation of the first controller 1420 and the second controller 1430 pointing at the object 1402. According to an embodiment of the disclosure, unlike simply pointing at a particular object, the operation of selecting the particular object may make it possible to move or delete the selected object. For example, where the position pointed at by the first controller, which points at the first object, is moved after the first controller and the second controller are associated with each other, the first object may also be moved as the first controller moves. However, simply pointing at the first object, the electronic device 200 may point at, highlight, and display the object corresponding to the position shifted as the first controller moves. For example, the electronic device 200 may display the object 1402 in a thick-bordered box, unlike the object 1403, as shown in FIG. 14.

[0162] FIG. 15A is a view illustrating an example in which an electronic device enlarges a selected object using two controllers (e.g., the first controller 1420 or the second controller 1430) according to an embodiment of the disclosure.

[0163] FIG. 15B is a view illustrating an example in which an electronic device shrinks a selected object using two controllers according to an embodiment of the disclosure.

[0164] Referring to FIGS. 15A and 15B, where the distance between the positions pointed at by the first controller and the second controller is within a threshold, the electronic device 200 may associate the two controllers with each other and control the operation of the display. As described above in connection with FIG. 14, where the first controller and the second controller both point at the first object in which case the distance between the positions pointed at by the first and second controllers is within the threshold, the electronic device 200 may “select” the first object. According to an embodiment of the disclosure, after the first controller is associated with the second controller, the electronic device 200 may associate the operation of the first controller with the operation of the second controller, controlling the operation of the display. For example, it is assumed in FIG. 15A that the first controller and the second controller simultaneously point at the first object 1402 to select the first object 1402. Where the first controller moves left, and the second controller moves right, i.e., in the opposite direction of the first controller, the electronic device 200 may determine that the first controller and the second controller move away from each other. Where the first controller and the second controller move away from each other so that the distance d between the first controller and the second controller increases, the electronic device 200 may enlarge (e.g., zoom in) and display the selected first object. For example, where the user pinches out with her two fingers on the touchscreen, the same operation as the touched object is enlarged may be performed.

[0165] Referring to FIG. 15B, where the first controller moves right, and the second controller moves left, i.e., the opposite direction of the first controller, with the first object enlarged, as described in connection with FIG. 15A, the electronic device 200 may determine that the first controller and the second controller come close to each other. Where the first controller and the second controller come close to each other so that the distance d between the first controller and the second controller decreases, the electronic device 200 may shrink (e.g., zoom out) and display the selected first object. According to an embodiment of the disclosure, the electronic device 200 may gradually shrink and display the first object based on the distance between the first controller and the second controller. For example, where the user pinches in with her two fingers on the touchscreen, the same operation as the touched object is shrunken may be performed.

[0166] According to an embodiment of the disclosure, where the distance between the first controller and the second controller is within the threshold, the operations of the first controller and the second controller may be determined in association with each other, and the electronic device 200 may apply various operations corresponding to the associated operations. For example, where the distance between the first controller and the second controller increases as shown in FIG. 15A, the electronic device 200 may enlarge the object. Where the distance between the first controller and the second controller decreases as shown in FIG. 15B, the electronic device 200 may shrink the object. Where the first controller and the second controller move with the distance between the first controller and the second controller maintained, the electronic device 200 may move the object.

[0167] FIG. 16 is a view illustrating an example in which an electronic device selects an object using two controllers according to an embodiment of the disclosure.

[0168] Referring to FIG. 16, an electronic device is configured to select an object using a first controller 1620 or a second controller 1625. According to an embodiment of the disclosure, where the distance between the position pointed at by the first controller and the position pointed at by the second controller is within a predetermined threshold, the electronic device 200 may associate the operation of the first controller with the operation of the second controller to make a determination. As noted above with reference to FIG. 14, an embodiment in which an object may be operated differently between when the object is pointed at by one controller and when the object is pointed at by two controllers. According to an embodiment of the disclosure, the electronic device 200 may select an object using one controller, and where the selected object is a media file (e.g., a video file), the electronic device 200 may execute the selected object by a predetermined operation. For example, where the first controller 1620 points at a first movie 1602, of the first movie 1602 and a second movie 1603 displayed on the display screen 1601, and the “run” button of the first controller 1620 is pressed, the electronic device 200 may perform control to play the first movie 1602. According to an embodiment of the disclosure, where the two controllers select an object in association with each other and an operation defined for the selected object is performed, the electronic device 200 may execute it in the form of a preview. For example, where the first controller 1620 points at position 1610 and the second controller 1625 points at 1621, which are within a predetermined distance from each other to select the first movie 1602, and the “run” button 1622 of the first controller 1620 or the second controller 1625 is pressed, the electronic device 200 may execute the first movie 1602 in a preview by generating a predetermined size of sub window 1630 for the first movie 1602 and playing the first movie 1602 in the sub window 1630.

[0169] According to an embodiment of the disclosure, the electronic device 200 may apply different display operations between when moving one controller or pressing the button and when moving the two controllers in association with each other or pressing the button to operations of the display (e.g., the selected object) defined corresponding to the movement of the controllers and the input of the buttons of the controllers.

[0170] FIG. 17 is a flowchart illustrating a method by which an electronic device displays a field of view using an HMD according to an embodiment of the disclosure.

[0171] Referring to FIG. 17, in operation 1701, the electronic device 200 (or the processor 210) may receive first data from the HMD through the communication circuit. The first data may include data obtained by the sensor of the HMD, e.g., data obtained by the proximity sensor of the HMD or data obtained by the IMU of the HMD.

[0172] In operation 1703, the processor 210 may determine whether the user wears the HMD based on the received first data. According to an embodiment of the disclosure, where the data obtained by the proximity sensor of the HMD in the first data is a predetermined threshold or less, the processor 210 may determine that the user wears the HMD, and where the data obtained by the proximity sensor of the HMD exceeds the predetermined threshold, the processor 210 may determine that the user does not wear the HMD. The predetermined threshold may be experimentally determined. Where the user is determined to wear the HMD, the processor 210 may perform operation 1705, and where the user does not wear the HMD, the processor 210 may repeat operation 1701.

[0173] In operation 1705, the processor 210 may set an initial position for the VR space based on an initial setting value. The initial setting value may be, e.g., the latest position referenced in the VR space or a predetermined start position in the VR space. According to an embodiment of the disclosure, the processor 210 may display a field of view in the VR space on the display with respect to the initial position in the VR space.

[0174] In operation 1707, the processor 210 may display the current position in the VR space, the position of the controller, and the position pointed at by the controller, based on the received first data. After displaying the HMD in the VR space based on data received from the HMD, the processor 210 waits to receive new data from the HMD.

[0175] FIGS. 18A and 18B are views illustrating examples in which an electronic device is operated by a voice command according to various embodiments of the disclosure.

[0176] According to an embodiment of the disclosure, the electronic device 200 may control the operation of the display using a plurality of controllers. According to an embodiment of the disclosure, the electronic device 200 may control the operation of the display based on data received from the input devices of the plurality of controllers. For example, among the plurality of controllers, the first controller may include a microphone, and the electronic device 200 may control the operation of the display corresponding to a voice command input to the microphone.

[0177] According to an embodiment of the disclosure, when the position of the first controller falls within a predetermined range, the electronic device 200 may control the display to display the predetermined range in the field of view and display a guide message operable by the voice command.

[0178] Referring to FIG. 18A, the electronic device 200 may display a plurality of objects 1802 and 1803 in the field of view and a microphone icon 1651 and a text message 1652 saying, “How can I help you?” in a portion 1650 of the field of view. The electronic device 200 may provide the microphone icon 1651 and the text message 1652 to induce the user to issue a voice command and may receive the voice command input to the microphone of the first controller. For example, where the user inputs a voice saying, “Look up new move releases today!” to the microphone of the first controller, the electronic device 200 may search for “movies to be released today” using an internet application, according to an embodiment of the disclosure.

[0179] Referring to FIG. 18B, according to an embodiment of the disclosure, the electronic device 200 may display an execution screen 1801 of the internet application that displays the results of searching for the move releases on the day.

[0180] According to an embodiment of the disclosure, the predetermined range where voice commands are available may be set as an area closest to the user’s mouth in the VR space. Where the first controller is a hand controller, when the user manipulates the first controller in her hand, the electronic device 200 may specify a portion of the VR space corresponding to the user’s mouth, and where the position of the first controller is included in the specified portion, the electronic device 200 may determine that the user has brought the first controller close to her mouth. According to an embodiment of the disclosure, the electronic device 200 may induce operations and provide functions, organically corresponding to the user’s manipulation of the controller, thereby increasing user convenience.

[0181] FIG. 19 is a view illustrating an example in which an electronic device assigns a right to control display to a plurality of controllers based on a physical position according to an embodiment of the disclosure.

[0182] Referring to FIG. 19, an electronic device 1901 may assign a display control right to at least one of a plurality of controllers to control the display screen using the plurality of controllers. According to an embodiment of the disclosure, the plurality of controllers may wirelessly or wiredly be connected with the electronic device. For example, a first head controller 1902 may be connected to the electronic device through a USB as denoted with reference numeral 1910, a first controller 1903 may be connected to the electronic device via BLE communication as denoted with 1920, and a second controller 1904 may be connected to the electronic device via BLE communication as denoted with 1930.

[0183] According to an embodiment of the disclosure, the electronic device 1901 may assign the display control right to the controller that is positioned physically closer to the electronic device 1901. For example, the electronic device 1901 may determine the position of the controller based on the strength of wireless communication signals (e.g., radio frequency (RF) signals) for the controllers connected to the electronic device 1901 and assign the display control right to the controller for which the wireless communication signal has the largest strength. As another example, the electronic device 1901 may measure the degree of proximity for at least one or more controllers connected via BLE communication. The electronic device 1901 may assign the display control right to the closest controller according to the BLE communication.

[0184] FIG. 20 is a view illustrating an example in which an electronic device 2001 (e.g., the electronic device 200) assigns a right to control display to a plurality of controllers based on priority according to an embodiment of the disclosure.

[0185] Referring to FIG. 20, an electronic device 2001 may identify priorities set for a plurality of controllers. For example, the electronic device 2001 may identify the respective priorities of the first controller 2002, the second controller 2003, and the third controller 2004 wirelessly or wiredly connected to the electronic device 2001, and upon determining that the priority of the first controller 2002 is highest, the electronic device 2001 may assign the display control right to the first controller 2002. For example, as shown in FIG. 20, the first controller 2002 having the display control right may be denoted in a solid line 2010, and the second controller 2003 and the third controller 2004 which have no display control right may be denoted in dashed lines 2011 or 2012.

[0186] According to an embodiment of the disclosure, where the first controller 2002, the second controller 2003, and the third controller 2004 have their priorities in the order thereof, the electronic device 2001 may assign a display control right to the third controller 2004 when only the third controller 2004 is connected to the electronic device 2001, assign a display control right to the second controller 2003 when the second controller 2003 is further connected to the electronic device 2001, and assign a display control right to the first controller 2002 when the first controller 2002 is then connected to the electronic device 2001. The electronic device 2001 may control the display based on the direction that the controller with the display control right indicates.

[0187] According to an embodiment of the disclosure, where the order of priority is from the first controller 2002 through the second controller 2003 to the third controller 2004, and the first controller 2002 indicates an outside of the field of view, the electronic device 2001 may assign a display control right to the second controller 2003. For example, the electronic device 2001 may assign a display control right based on whether the plurality of controllers point within the field of view and the priorities of the controllers.

[0188] FIG. 21 is a view illustrating an example in which an electronic device assigns a right to control display to a plurality of controllers based on operation of at least one of the plurality of controllers according to an embodiment of the disclosure.

[0189] Referring to FIG. 21, the electronic device 200 may detect a motion of the user who wears the HMD 2101 and holds the second controller 2103 in her hand without using the first controller 2102 and may assign a display control right to at least one controller among the plurality of controllers. For example, when the user moves her right hand as shown in FIG. 21, the electronic device 200 may sense the motion of the second controller 2103 and assign a display control right to the first controller 2102.

[0190] FIG. 22 illustrates an example in which an electronic device performs a plurality of pointing events using a plurality of controllers according to an embodiment of the disclosure.

[0191] Referring to FIG. 22, the electronic device may use a plurality of controllers to control a plurality of functions (or objects) on the display 2210. Referring to FIG. 22, the electronic device 200 may provide a virtual game application that is operated with a plurality of characters and may display an execution screen 2310 of the game application in the field of view. For example, the first controller 2201, the second controller 2202, the third controller 2213, and the fourth controller 2204 may control the first character 2211, the second character 2212, the third character 2213, and the fourth character 2214, respectively. The electronic device 200 may control the first controller 2201 to the fourth controller 2204 so that their respective operations do not conflict with each other.

[0192] As is apparent from the foregoing description, according to the embodiments of the disclosure, the electronic device may provide the user with various manipulations to control the display of the electronic device using a plurality of different controllers.

[0193] According to the embodiments of the disclosure, the electronic device may reflect the user’s intent to assign a right to control the display to at least one of a plurality of controllers.

[0194] According to the embodiments of the disclosure, the electronic device may switch and re-assign the right to control the display between the plurality of controllers corresponding to the user’s natural manipulation.

[0195] While the disclosure has been shown and described with reference to various embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the disclosure as defined by the appended claims and their equivalents.
