Description

DISPLAY SETTINGS CHANGES BASED ON LOCATIONS

BACKGROUND

[0001] An electronic device, for example, a laptop, tablet, or smartphone, may display content, for example, on a content-displaying area of a display device of the electronic device. The content-displaying area may be extended to an external display device of an external electronic device when the external electronic device is connected to the electronic device, so as to expand the total content-displaying area.

[0002] The content which is displayed in the content-displaying area extended between the electronic device and the external electronic device may be manually arranged or oriented. For example, a user may make manual inputs to an electronic device to change a display setting to arrange the displays in a particular orientation.

DETAILED DESCRIPTION

[0009] Various examples of the disclosure will now be described with reference to the accompanying drawings, wherein like reference characters denote like elements. Examples to be explained in the following may be modified and implemented in various different forms.

[0010] As mentioned above, when an electronic device is connected to an external display device so that a content-displaying area can be extended, the display settings of the electronic device may need to be manually adjusted if a default setting of the display settings, which assumes a particular arrangement of the electronic device relative to the external electronic device, does not match the actual arrangement of the electronic device relative to the external electronic device. Manually changing the display settings causes an inconvenience to the user. Additionally, a user who is unfamiliar with how to change the display settings may become confused when there is a mismatch between the display settings and the actual arrangement of the electronic device relative to the external electronic device.

[0011] According to examples described herein, display settings of a display device of an electronic device may be changed automatically or without user input based on a location of the electronic device relative to the external electronic device. For example, the electronic device may determine its location relative to the external electronic device based on location information received from the external electronic device.

[0012] For example, the location of the electronic device may be determined by using ultra-wideband (UWB) radio technology. Compared to BLUETOOTH or WI-FI, UWB radio technology may enable very accurate real-time measurements of a location of an object. For example, UWB radio technology may use a time-of-flight of a radio frequency signal to calculate a distance from a transmitting or initiating UWB device (e.g., a UWB transceiver tag) to a receiving or responding UWB device (e.g., a UWB transceiver anchor). The accuracy of the distance calculation may be about 5 to 30 cm, for example, about 10 cm. The physical properties of the UWB radio frequency signal also enables real-time, reliable localization, and data communication. It is also energy efficient due to its ultra-short air time.

[0013] According to examples described herein, the electronic device may determine its relative location to the external electronic device by using a UWB transceiver tag included with the electronic device, and a UWB transceiver anchor included with the external electronic device which receives a radio frequency signal transmitted from the UWB transceiver tag. For example, the external electronic device to which a content-displaying area of the electronic device is extendable may be a smart display. According to examples described herein, the UWB transceiver anchor may include three receiving antennas so that a real-time three-dimensional location of the electronic device relative to the UWB transceiver anchor included in the external electronic device, may be determined.

[0014] For example, the electronic device may be connected to an external electronic device (smart display) via an High-Definition Multimedia Interface (HDMI) cable, to extend the content-displaying area of the electronic device to the external electronic device. In response to the HDMI cable being connected to the external electronic device, the electronic device may initiate ranging with the external electronic device. That is, the UWB transceiver tag of the electronic device may exchange ranging messages with the UWB transceiver anchor of the external electronic device. The external electronic device may measure the three-dimensional location of the electronic device relative to the

UWB transceiver anchor included in the external electronic device. [0015] The real-time three-dimensional location information of the electronic device may be transmitted from the external electronic device to the electronic device. For example, the location information may be transmitted over the data channel provided by the UWB transceivers.

[0016] In response to receiving the location information, the electronic device may determine its location relative to the external electronic device and may change or adjust display settings to match the physical arrangement of the electronic device and the external electronic device. For example, the electronic device may change or adjust display settings of a display device to match the physical arrangement of the electronic device and the external electronic device by calling an application programming interface. Therefore, a user does not need to manually change the display settings of the electronic device when the location of the electronic device is changed or when the location of the electronic device relative to the external electronic device does not correspond to a default setting assumed in the display settings.

Additionally, a user does not need to have knowledge of how to change or adjust display settings of the display device of the electronic device.

[0017] Referring to FIG. 1 , a block diagram of an electronic device and external electronic device is illustrated, according to examples of the disclosure.

[0018] The electronic device 100 may include a processor 110, a display device 120, a storage device 130, a controller 140, a user interface 150, a communication interface 160, a location-based display setting application 170, and a sensor 180. The electronic device 100 may include, but is not limited to, notebook computers, tablets, smart phones, and the like. The electronic device

100 may include other components which are not shown in FIG. 1 , and is not limited to the example components shown in FIG. 1 . That is, the electronic device 100 may include more or less components than those shown in FIG. 1. For example, the electronic device 100 may include an operating system (OS) and a basic input/output system (BIOS).

[0019] The processor 110 of the electronic device 100 may execute instructions stored in the storage device 130. The processor 110 may include, for example, an arithmetic logic unit, a central processing unit (CPU), a graphics processing unit (GPU), a digital signal processor (DSP), an image processor, a microcomputer, a field programmable array, a programmable logic unit, an application-specific integrated circuit (ASIC), a microprocessor, or combinations thereof.

[0020] The display device 120 may include a liquid crystal display (LCD), a light emitting diode (LED) display, an organic light emitting diode (OLED) display, active matrix organic light emitting diode (AMOLED), flexible display, 3D display, a plasma display panel (PDP), a cathode ray tube (CRT) display, and the like, for example. The display device 120 may also include a touchscreen display to receive a user input.

[0021] The storage device (e.g., memory) 130 of the electronic device 100 may include, for example, a computer readable storage medium which may be any electronic, magnetic, optical, or other physical storage device that stores executable instructions. For example, the storage device 130 may include a nonvolatile memory device, such as a Read Only Memory (ROM), Programmable Read Only Memory (PROM), Erasable Programmable Read Only Memory (EPROM), and flash memory, a USB drive, a volatile memory device such as a Random Access Memory (RAM), a hard disk, floppy disks, a blue-ray disk, or optical media such as CD ROM discs and DVDs, or combinations thereof.

[0022] The electronic device 100 may include a controller 140. The controller 140 may be an embedded controller, for example. The controller 140 may be used for various operations of the electronic device 100. For example, the controller 140 may act as a pass-through for communications between the communication interface 160 and the processor 110. For example, the controller 140 may be connected with the communication interface 160 via a Serial Peripheral Interface (SPI). For example, the controller 140 may act as a pass-through for communications between the UWB transceiver 161 and the processor 110 via the SPI. The controller 140 may also perform security-related functions when the electronic device 100 is powered off.

[0023] The electronic device 100 may include a user interface 150 to receive an input from a user to control an operation of the electronic device 100, and the display device 120 may display information regarding the electronic device 100. The user interface 150 may include, for example, a keyboard, a mouse, a joystick, a button, a switch, an electronic pen or stylus, a gesture recognition sensor, an input sound device or voice recognition sensor such as a microphone, an output sound device such as a speaker, a track ball, a remote control, a touchscreen, or combinations thereof. The display device 120 may also act as a user interface when the display device 120 includes a touchscreen, for example.

[0024] The electronic device 100 may include a communication interface 160. Electronic device 100 may be connected with or communicate with the external electronic device 200, for example through communication interface 160 via a wired or wireless connection. The wireless connection may be over a network such as a wireless local area network (WLAN), wide area network (WAN), WI-FI Direct or the like, and an ultra-wideband (UWB) network. For example, a wired communication connection may be made via a pair cable, a coaxial cable, an optical fiber cable, an Ethernet cable, and the like.

[0025] The electronic device 100 may include a UWB transceiver 161 which may be used to transmit and receive information, for example ranging messages, through a UWB network. For example, the UWB transceiver 161 may be disposed at and integerated with the electronic device 100. For example, the UWB transceiver 161 may be disposed at a central portion of the electronic device 100. The UWB transceiver 161 may include an integrated circuit (IC) chip and an antenna or a plurality of antennas, for example. For example, UWB transceiver 161 may include one transmitting antenna and one receiving antenna. For example, the UWB communication may be performed at frequencies ranging from 3.1 GHz to 10.5 GHz, where each channel has a bandwidth of at least 500 MHz. [0026] The electronic device 100 may include an HDMI connector (port) 162 which may be used to connect the electronic device 100 to external electronic device 200 to expand a content-displaying area of the electronic device 100 to the external electronic device 200. For example, the content-displaying area may correspond to a desktop user interface which may be extendable over the display device 120 and external display device 220.

[0027] For example, the external electronic device 200 acts as an extra screen or display monitor in which content may be extended between the screen or display device 120 of the electronic device 100 and the screen or external display device 220 of the external electronic device 200. However, the disclosure is not limited to a HDMI connector and other types of connectors may be utilized. For example, the electronic device 100 may be connected to external electronic device 200 to expand a content-displaying area of the electronic device 100 via a USB connector, a DisplayPort connector, Digital Visual Interface (DVI) connector, and the like.

[0028] The electronic device 100 may include a location-based display setting application 170. The location-based display setting application 170 may include a program which includes instructions executed by the processor 110 to change a display setting of the display device 120, based on a location of the electronic device 100 relative to the external electronic device 200. For example, the location-based display setting application 170 may be a program which includes instructions executed by the processor 110 to automatically change a display setting of the display device 120, without receiving an input from a user of the electronic device 100, by calling an application programming interface (API) and setting various parameters to change the display settings of the display device 120. For example, a position of the external display device 220 of the external electronic device 200 may be set relative to a position of the display device 120 of the electronic device 100 by calling the API. For example, the external display device 220 of the external electronic device 200 may be set as a primary or main display by calling the API.

[0029] For example, the primary or main display may correspond to whether the electronic device 100 or the external electronic device 200 is disposed at a particular position. For example, if the electronic device 100 is determined to be disposed to the left of the external electronic device 200, the display setting may be set, via a first call of the API, so that the display device 120 of the electronic device 100 is configured as the primary or main display, and the external display device 220 of the external electronic device 200 is configured as an external or extended display. For example, another display setting may be set via a second call of the API to set a position of the external or extended display. The position of the external or extended display may be set relative to the primary display, for example in terms of a horizontal position relative to the primary display (a width of the primary display), a vertical position relative to the primary display (a height of the primary display), or combinations thereof.

[0030] The electronic device 100 may include a sensor 180 to measure or determine whether the electronic device 100 is moved. For example, the sensor 180 may include an accelerometer to detect movement of the electronic device 100. When the sensor 180 indicates the electronic device 100 has been or is being moved, a location of the electronic device 100 may need to be determined again and the display settings of the electronic device 100 may need to be adjusted or changed.

[0031] The location-based display setting application 170 may include an application or program which includes instructions executed by the processor 110 to detect if the electronic device 100 has been or is being moved, and then initiate ranging with the external electronic device 200 to determine a location of the electronic device 100 relative to the external electronic device 200. Without the sensor 180, the ranging may be done periodically, once per second for example, which may consume more power than if the ranging is triggered by the sensor 180.

[0032] The external electronic device 200 may include components similar to the electronic device 100, such as a processor 210, an external display device 220, a storage device (e.g., memory) 230, a controller 240, a user interface 250, and a communication interface 260 including a UWB transceiver 261 and a HDMI connector 262, and repeated descriptions of these components and their operations will be omitted for the sake of brevity. For example, the UWB transceiver (UWB transceiver anchor) 262 may include one transmitting antenna and three receiving antennas. The external electronic device 200 may include, but is not limited to, smart displays, laptops, tablets, smart phones, and the like. [0033] The external electronic device 200 may include a location-based display setting application 270. The location-based display setting application 270 may include an application or program which includes instructions executed by the processor 210 to control the UWB transceiver 261 to exchange ranging messages with the UWB transceiver 161 of the electronic device 100, in response to the external electronic device 200 being connected to the electronic device 100 via an HDMI cable (or in response to the electronic device 100 being connected to the external electronic device 200 to expand a content-displaying area between display devices 120, 220). For example, the location-based display setting application 270 may be a program which includes instructions executed by the processor 210 to automatically measure and transmit location information of the electronic device 100 relative to the external electronic device 200 to enable the electronic device 100 to change a display setting of the display device 120, without receiving an input from a user of the electronic device 100, by calling an application programming interface (API) and setting various parameters to change the display settings of the display device 120. [0034] The location-based display setting application 270 may include an application or program which includes instructions executed by the processor 210 to send a message to the electronic device 100 indicating the electronic device 100 has a new or changed location relative to the external electronic device 200. For example, the above-described message may be transmitted via a UWB communication protocol. A UWB frame may carry up to 127 bytes of payload and the above-described message may be carried by a UWB frame. [0035] Referring to FIGS. 2A-2C, example arrangements of the electronic device relative to the external electronic device are illustrated, according to examples of the disclosure.

[0036] In FIG. 2A, the electronic device 100 is disposed to the left of the external electronic device 200. For example, a default display setting of the electronic device 100 may be set by an operating system (for example Windows) of the electronic device 100 when the electronic device 100 is connected to the external electronic device 200 via an HDMI connection. For example, the default display setting may assume that electronic device 100 is positioned to the left of the external electronic device 200 and define the content-displaying area such that a cursor 121 displayed in the content-displaying area on a screen of the display device 120 of the electronic device 100 may be moved to the right and off the right-hand side of the screen of the display device 120 and onto the left-hand side of the screen of the external display device 220 (i.e., the monitor) of the external electronic device 200. Similarly, the default display setting may provide that if the cursor 121 is displayed in the content-displaying area on the screen of the external display device 220 of the external electronic device 200, the cursor 121 may be moved to the left and off the left-hand side of the screen of the external display device 220 and onto the right-hand side of the screen of the display device 120 (i.e., the monitor) of the electronic device 100. Windows or other objects displayed in the content-displaying area may also be moved between the screens of the electronic device 100 and external electronic device 200 according to this defined right-left directionality. [0037] However, if the electronic device 100 is not initially disposed to the left of the external electronic device 200, then the default display setting may not be appropriate and may cause confusion to a user as the movement of the cursor 121 may not correspond to the actual arrangement of the electronic device 100 and external electronic device 200. For example, if the electronic device 100 were disposed to the right of the external electronic device 200 as in FIG. 2C, a user may naturally attempt to move the cursor 121 to the left and onto the screen of the external electronic device 200. However, under the default display setting, the cursor 121 would not be allowed to move off of the left-hand side of the screen of the electronic device 100 and instead may be stopped. According to examples of the disclosure described herein, the location of the electronic device 100 relative to the external electronic device 200 may be determined by the external electronic device 200, for example, automatically, and the display setting of the electronic device 100 may be changed or adjusted accordingly so that movement of the cursor 121 or the arrangement of content displayed in the content-displaying area corresponds to the actual arrangement of the electronic device 100 and external electronic device 200. Thus, user inconvenience may be avoided.

[0038] In FIG. 2B, the electronic device 100 is disposed in front of and below the external electronic device 200. For example, an example display setting of the electronic device 100 to be applied in such a configuration may define the content-displaying area such that a cursor 121 displayed in the contentdisplaying area on a screen of the display device 120 of the electronic device 100 may be moved upward and off the upper edge of the screen of the display device 120 and onto the lower portion of the screen of the external display device 220 (i.e., the monitor) of the external electronic device 200. Similarly, the example display setting may provide that if the cursor 121 is displayed in the content-displaying area on the screen of the external display device 220 of the external electronic device 200, the cursor 121 may be moved downward and off the lower edge of the screen of the external display device 220 and onto the upper portion of the screen of the display device 120 (i.e., the monitor) of the electronic device 100. Windows or other objects displayed in the contentdisplaying area may also be moved between the screens of the electronic device 100 and external electronic device 200 according to this defined up- down directionality. According to examples of the disclosure, the electronic device 100 may set the display setting of the electronic device 100 according to this defined up-down directionality when the electronic device 100 determines its relative location to the external electronic device 200 is similar to that shown in FIG. 2B.

[0039] In FIG. 2C, the electronic device 100 is disposed to the right of the external electronic device 200. For example, an example display setting of the electronic device 100 to be applied in such a configuration may define the content-displaying area such that a cursor 121 displayed in the contentdisplaying area on a screen of the display device 120 of the electronic device 100 may be moved to the left and off the left-hand side of the screen of the display device 120 and onto the right-hand side of the screen of the external display device 220 (i.e., the monitor) of the external electronic device 200. Similarly, the example display setting may provide that if the cursor 121 is displayed in the content-displaying area on the screen of the external display device 220 of the external electronic device 200, the cursor 121 may be moved to the right and off the right-hand side of the screen of the external display device 220 and onto the left-hand side of the screen of the display device 120 (i.e. , the monitor) of the electronic device 100. Windows or other objects displayed in the content-displaying area may also be moved between the screens of the electronic device 100 and external electronic device 200 according to this defined left-right directionality. According to examples of the disclosure, the electronic device 100 may set the display setting of the electronic device 100 according to this defined left-right directionality when the electronic device 100 determines its relative location to the external electronic device 200 is similar to that shown in FIG. 2C.

[0040] Possible arrangements of the electronic device 100 and the external electronic device 200 are not limited to the examples illustrated in FIGS. 2A-2C. For example, the electronic device 100 may be disposed above external electronic device 200, or may be disposed at a diagonal. Furthermore, the electronic device 100 may be connected to more than one external electronic device 200. For example, a first external electronic device may be disposed to the right of electronic device 100 and a second external electronic device may be disposed to the left of electronic device 100. The electronic device 100 may detect or determine its location relative to each of the first and second external electronic devices. For example, the electronic device 100 may apply display settings corresponding to a combination of those discussed above with respect to the display settings applied in FIGS. 2A and 2C.

[0041] Referring to FIG. 3, an example system for changing a display setting based on a location of an electronic device relative to an external electronic device is illustrated, according to examples of the disclosure. Further, referring to FIG. 4, an example configuration of antennas of a UWB transceiver of the external electronic device is illustrated, according to examples of the disclosure. [0042] In FIG. 3, the electronic device 100 may be connected to the external electronic device 200 via a cable 330, for example an HDMI cable, so that a content-displaying area may be extended between the display device 120 and external display device 220. The UWB transceiver (UWB transceiver tag) 161 may be integrated in the electronic device 100 and may communicate and exchange information over a UWB network with UWB transceiver (UWB transceiver anchor) 261 of the external electronic device 200.

[0043] For example, UWB transceiver 161 may include one transmitting antenna and one receiving antenna, and the UWB transceiver 261 may include one transmitting antenna and three receiving antennas. With two receiving antennas, the UWB transceiver 261 may measure both a range and an angle of arrival to resolve a two-dimensional position of the UWB transceiver 161 . With three receiving antennas, the UWB transceiver 261 may measure a range of the UWB transceiver and both horizontal and vertical angles of arrival to resolve a three-dimensional position of the UWB transceiver 161 . For example, the UWB transceiver 261 of the external electronic device 200 may calculate or determine a location of the electronic device 100 relative to the external electronic device 200. The real-time relative location information may be shared or transmitted from the external electronic device 200 to the electronic device 100 over a data channel provided by the UWB transceivers 161 , 261 .

[0044] For example, as illustrated in FIG. 3, the UWB transceiver 261 may be disposed and integrated with the external electronic device 200 at a location corresponding to an intersection of a vertical axis 310 and a horizontal axis 320, each of which pass through some portion of the external electronic device 200. For example, the UWB transceiver 261 may be disposed at a front portion or a front and central portion of the external electronic device 200. As illustrated in FIG. 4, the UWB transceiver 261 may include three receiving antennas 261a, 261 b, and 261 c, which are arranged in an L-shape. For example, antenna 261 a may be spaced apart from antenna 261 b in a vertical direction (along axis 310) by one-half a wavelength (A 12) and antenna 261 b may be spaced apart from antenna 261c in a horizontal direction (along axis 320) by one-half a wavelength (A 12). However, the disclosure is not so limited to this example arrangement of the antennas and the antennas may be oriented in another manner. The wavelength A may correspond to a frequency for UWB communication. For example, a frequency for UWB communication of 6 GHz has a wavelength of about 5 centimeters. Therefore, a distance between antennas 261a and 261 b may correspond to about 2.5 cm for UWB communication of 6 GHz. [0045] The UWB transceiver 261 may measure a three-dimensional position of the electronic device 100 relative to the external electronic device 200 using the receiving antennas 261 a, 261 b, and 261c. For example, a distance "d" to the electronic device 100 may be measured, a horizontal angle of arrival "h" may be measured, and a vertical angle of arrival "v" may be measured.

[0046] For example, the position or location information of the electronic device 100 may be detected by the external electronic device 200 at a specified interval of time (for example, the electronic device 100 initiates ranging every one second), or may be detected according to a specified condition (for example, the electronic device 100 initiates ranging when it detects movement by its sensor 180).

[0047] For example, the position or location information of the electronic device 100 may be transmitted by the external electronic device 200 to the electronic device 100 each time the external electronic device 200 detects the location of the electronic device 100, when the location of the electronic device 100 is determined to have changed by a threshold amount compared to a previous location of the electronic device 100, or when the location of the electronic device 100 is detected for a first time by the external electronic device 200.

[0048] Referring to FIG. 5, and in view of FIGS. 1 through 4, example operations (method operations) of the electronic device 100 will be described.

[0049] For example, the electronic device 100 includes the display device 120 to display content in a content-displaying area. At operation 510, the contentdisplaying area may be extended to the external display device 220 of the external electronic device 200, for example by connecting the electronic device 100 to the external electronic device 200 using an HDMI cable 310.

[0050] At operation 520 the processor 110 of the electronic device 100 may set a display setting of the display device 120 to a default setting or to a previous display setting if the external electronic device 200 has been connected to the electronic device 100 previously.

[0051] At operation 530, the UWB transceiver 161 may initiate ranging (exchange ranging messages) with the external electronic device 200 to enable the external electronic device 200 to measure or determine a position (determine location information) of the electronic device 100. For example, when the UWB transceiver 161 is within an operating range of UWB transceiver 261 , UWB transceiver 161 may exchange the ranging messages with the external electronic device 200 via a UWB communication protocol. For example, the electronic device 100 may initiate ranging or exchange ranging messages with the external electronic device 200 via the UWB communication protocol in response to the electronic device 100 being connected to the external electronic device 200 via the HDMI cable 310.

[0052] For example, the UWB transceiver 161 may act as an initiator to initiate a range measurement while UWB transceiver 261 may act as a responder which listens and responds to UWB transceiver 161 .

[0053] For example, the UWB transceiver 261 may calculate the range (distance) between UWB transceiver 161 and UWB transceiver 261. In examples described herein, the azimuth or angle of arrival information of the UWB transceiver 161 with respect to the UWB transceiver 261 may also be calculated by the UWB transceiver 261 . For example, distance information of the UWB transceiver 161 with respect to the UWB transceiver 261 , as well as both horizontal and vertical angles of arrival of the UWB transceiver 161 with respect to the UWB transceiver 261 , may be calculated by the UWB transceiver 261. The range (distance) between UWB transceiver 161 and UWB transceiver 261 may be calculated based on a time-of-flight estimation using timestamps of transmission and reception times which are included in the ranging messages exchanged between the UWB transceiver 161 and UWB transceiver 261. A plurality of messages, may be exchanged between the UWB transceiver 161 and UWB transceiver 261 so that the range (distance) may be calculated. For example, two, three, or four messages may be exchanged between the UWB transceiver 161 and UWB transceiver 261 to calculate the range. However, the disclosure is not limited to these examples, and more than four messages may be exchanged. Measurement error may be reduced as more messages are sent; however, time and power may be saved as fewer messages are sent. As another example, a time difference of arrival (TDoA) method may be utilized to determine a location of the UWB transceiver 161 relative to the UWB transceiver 261.

[0054] For example, the UWB transceiver 261 may include a plurality of receiving (RX) antennas (e.g., antennas 261a-261c), and the UWB transceiver 261 may measure angle of arrival (AOA) information in both a horizontal and a vertical direction. [0055] At operation 540, the UWB transceiver 161 may receive real-time position data (location information) of the electronic device 100 from the external electronic device 200. For example, the location information of the electronic device 100 may include horizontal angle of arrival information, vertical angle of arrival information, and distance information.

[0056] At operation 550, the processor 110 of the electronic device 100 may determine a location of the electronic device 100 relative to the external electronic device 200 based on the position data (location information).

[0057] At operation 560, the processor 110 may change a display setting of the display device 120 to rearrange the content displayed in the content-displaying area based on the location of the electronic device 100 relative to the external electronic device 200.

[0058] For example, when the processor 110 determines the location of the electronic device 100 relative to the external electronic device 200 has changed (for example, compared to a previous location of the electronic device 100), the processor 110 may change the display setting of the display device 120 by setting the external display device 220 as a primary display and by setting a position of the electronic device 100.

[0059] For example, the processor 110 may change the display setting of the display device 120 and set the position of the external display device 220 via an application programming interface which is part of or called by the locationbased display setting application 170. [0060] For example, when the processor 110 determines the location of the electronic device 100 relative to the external electronic device 200 has changed (for example, compared to a previous location of the electronic device 100), the processor 110 may change the display setting by setting one of the display device 120 and the external display device 220 as a primary or main display, by setting the other one of the display device 120 and the external display device 220 as an extended display, and by setting a position of the extended display with respect to the primary display. For example, the processor 110 may change the display setting of the display device 120 and set the position of the external display device 220 via an application programming interface which is part of the location-based display setting application 170.

[0061] As an example, when the processor 110 determines the location of the electronic device 100 relative to the external electronic device 200 has changed from a relative position as that shown in FIG. 2A, to the relative position as that shown in FIG. 2C, the processor 110 may change the display setting by setting the external display device 220 as a primary or main display, by setting the display device 120 as an extended display, and by setting a position of the display device 120 with respect to the external display device 220 to indicate that the display device 120 and external display device 220 are at a same height and that the external display device 220 is to the left of the display device 120. Therefore, the cursor 121 or other objects or windows, and the like, may be moved in the content-displaying area between the display device 120 and external display device 220 intuitively and without causing user confusion. [0062] Operations 530 through 560 may be repeated at a regular or irregular time interval, so that a location of the electronic device 100 may be tracked or updated. For example, operations 530 through 560 may be repeated according to instructions of the location-based display setting application 170.

[0063] According to an example, the electronic device 100 may include a sensor 180 to detect a movement of the electronic device 100. For example, the sensor 180 may include an accelerometer to detect a movement of the electronic device 100. For example, the processor may control the UWB transceiver 161 to exchange ranging messages with the external electronic device 200 in response to the sensor 180 (accelerometer) detecting movement of the electronic device 100. The processor may control the UWB transceiver 161 to exchange ranging messages with the external electronic device 200 in response to the sensor 180 (accelerometer) detecting movement of the electronic device 100 is greater than a threshold amount (e.g., when an acceleration of greater than 1 m/s² is detected). For example, operations 530 through 560 may be repeated according to instructions of the location-based display setting application 170 when the sensor 180 (accelerometer) detects movement of the electronic device 100 or when the sensor 180 (accelerometer) detects movement of the electronic device 100 is greater than a threshold amount.

[0064] Referring to FIG. 6, and in view of FIGS. 1 through 5, example operations (method operations) of the external electronic device 200 will be described. [0065] For example, the external electronic device 200 includes the external display device 220 to display content in a content-displaying area. At operation 610, the content-displaying area may be extended between the display device 120 of the electronic device 100 and the external display device 220 of the external electronic device 200, for example by connecting the electronic device 100 to the external electronic device 200 using an HDMI cable 310.

[0066] At operation 620, the UWB transceiver 261 may exchange ranging messages (first ranging messages) with the electronic device 100 by responding to ranging messages initiated by the electronic device 100.

[0067] At operation 630 the UWB transceiver 261 may measure or determine a real-time position (determine first location information) of the electronic device 100. For example, the first location information may be stored in storage device 230. The UWB transceiver 261 may exchange the ranging messages with the electronic device 100 via a UWB communication protocol. For example, the electronic device 100 may initiate ranging or exchange ranging messages with the external electronic device 200 via the UWB communication protocol in response to the electronic device 100 being connected to the external electronic device 200 via the HDMI cable 310.

[0068] In a subsequent execution of operations 620 and 630, the external electronic device 200 may exchange ranging messages (second ranging messages) with the electronic device 100 and again measure or determine a real-time position (determine second location information) of the electronic device 100. For example, the second location information may be stored in storage device 230. For example, the external electronic device 200 may exchange the second ranging messages with the electronic device 100 via the UWB communication protocol. For example, the UWB transceiver 261 may exchange the second ranging messages with the electronic device 100 after exchanging the first ranging messages with the electronic device 200, where the electronic device 100 may initiate the ranging messages periodically at regular intervals (e.g., every second) or at irregular intervals.

[0069] For example, the UWB transceiver 261 may include a plurality of receiving antennas 261 a-261 c to measure or determine the first location information and the second location information of the electronic device 100.

The first location information and the second location information of the electronic device 100 may indicate a three-dimensional location of the electronic device 100 relative to the external electronic device 200. The external electronic device 200 may measure and transmit the three-dimensional position or location information of the electronic device 100 to the electronic device 100 over the UWB network, in real-time.

[0070] At operation 640, the processor 210 may determine whether the position of the electronic device 100 has changed. For example, the processor 210 may compare the first location information with the second location information.

When the second location information is different from the first location information, for example by a threshold amount, the processor 210 may determine that the position (location) of the electronic device 100 has changed.

Operation 640 may be omitted when external electronic device 200 is determining the position of the electronic device 100 for a first time after the electronic device 100 is connected to the external electronic device 200 via the HDMI cable.

[0071] At operation 650, in response to the processor 210 determining the location of the electronic device 100 has changed, the processor 210 may control the UWB transceiver 261 to transmit real-time position data of the electronic device 100 (the second location information) from the external electronic device 200 to the electronic device 100, for the electronic device 100 to change a display setting of the display device 120 based on the second location information. If the processor 210 determines the location of the electronic device 100 has not changed, the process may return to operation 620 which may be performed at a regular or irregular interval according to ranging messages initiated by the electronic device 100.

[0072] In a variation of the operations illustrated in FIG. 6 at operation 620, the electronic device 100 may initiate ranging with the external electronic device 200 based on an output of the sensor 180 which is an example in which ranging messages may be exchanged at an irregular interval.

[0073] In another variation of the operations illustrated in FIG. 6, operation 640 may be omitted and real-time position data of the electronic device 100 may be transmitted from the external electronic device 200 to the electronic device 100 each time it is measured regardless of whether the location information of the electronic device 100 has changed compared to previous location information measured by the external electronic device 200. [0074] FIG. 7 illustrates an example apparatus 1000 for changing display settings of an electronic device based on a location of the electronic device relative to an external electronic device, according to examples of the disclosure.

[0075] In an example, the apparatus 1000 may be the electronic device 100.

The apparatus 1000 includes the processor 110 and storage device (non- transitory computer readable storage medium) 130, where the term “non- transitory” does not encompass transitory propagating signals. The non- transitory computer readable storage medium 130 may include instructions 1010, 1020, 1030, 1040, and 1050 that, when executed by the processor 110, cause the processor 110 to perform various functions. For example, the instructions 1010, 1020, 1030, 1040, and 1050 may be instructions executed via the location-based display setting application 170.

[0076] The instructions 1010 may include instructions for the electronic device 100 to set a display setting of the display device 120 using a default or a previous display setting. For example, the electronic device 100 may set the display setting of the display device 120 using the default or the previous display setting in response to the electronic device 100 being connected (e.g., via an HDMI cable) to the external electronic device 200 to extend a contentdisplaying area between display devices 120, 220.

[0077] Instructions 1020 may include instructions to initiate ranging with external electronic device 200 to enable the external electronic device 200 to measure a position of the electronic device 100. For example, the electronic device 100 may initiate ranging (exchange ranging messages) in response to the electronic device 100 being connected (e.g., via the HDMI cable) to the external electronic device 200 to extend the content-displaying area between display devices 120, 220. For example, the electronic device 100 may initiate ranging (exchange ranging messages) with the external electronic device 200 using a UWB communication protocol.

[0078] Instructions 1030 may include instructions to receive real-time position data of the electronic device 100 from external electronic device 200.

[0079] Instructions 1040 may include instructions to, in response to the electronic device 100 receiving the position data, determine the location of the electronic device 100 relative to the external electronic device 200, based on the position data.

[0080] Instructions 1050 may include instructions for the electronic device 100 to change a display setting of the electronic device 100 based on the location of the electronic device 100 relative to the external electronic device 200. For example, the electronic device 100 may change the display setting of the display device 120 and set the position of the external display device 220 via an application programming interface which is part of or called by the locationbased display setting application 170.

[0081] Additional instructions may be stored in the non-transitory computer readable storage medium 130 to perform various other functions of the electronic device 100 which are described herein. For example, additional instructions may include instructions to initiate ranging messages with the external electronic device 200, in response to a sensor 180 of the electronic device 100 detecting movement of the electronic device 100.

[0082] FIG. 8 illustrates an example apparatus 1100 for changing display settings of an electronic device based on a location of the electronic device relative to an external electronic device, according to examples of the disclosure.

[0083] In an example, the apparatus 1100 may be the external electronic device 200. The apparatus 1100 includes the processor 210 and storage device (non- transitory computer readable storage medium) 230. The non-transitory computer readable storage medium 230 may include instructions 1110, 1120, 1130, and 1140 that, when executed by the processor 210, cause the processor 210 to perform various functions. For example, the instructions 1110, 1120, 1130, and 1140 may be instructions executed via the location-based display setting application 270.

[0084] The instructions 1110 may include instructions for the external electronic device 200 to exchange ranging messages with UWB transceiver 161 of the electronic device 100. For example, the external electronic device 200 may exchange ranging messages with the electronic device 100, in response to the electronic device 100 being connected (e.g., via the HDMI cable) to the external electronic device 200 to extend the content-displaying area between display devices 120, 220 and the UWB transceiver 161 of the electronic device 100 initiating ranging messages. For example, the ranging messages may be exchanged using a UWB communication protocol. [0085] Instructions 1120 may include instructions for the external electronic device 200 to measure the real-time position of the electronic device 100. For example, the UWB transceiver 261 may include a plurality of receiving antennas 261a-261 c to measure or determine location information of the electronic device 100. The location information of the electronic device 100 may indicate a three- dimensional location of the electronic device 100 relative to the external electronic device 200.

[0086] Instructions 1130 may include instructions for the external electronic device 200 to determine whether the position of the electronic device 100 has changed from a previous position. For example, the external electronic device 200 may compare the measured location information with previous location information of the electronic device 100. When the measured location information is different from the previous location information, for example by a threshold amount, the external electronic device 200 may determine that the position (location) of the electronic device 100 has changed.

[0087] Instructions 1140 may include instructions for the external electronic device 200 to, in response to a determination that a position of the electronic device 100 has changed, for example by a threshold amount, transmit real-time position data of the electronic device 100 to the electronic device 100. If the position of the electronic device 100 has not changed, or if the position of the electronic device 100 has not changed by the threshold amount, the external electronic device 200 may not transmit the real-time position data to the electronic device 100. [0088] According to the above-described examples, display settings of an electronic device, which is connected to an external electronic device so that content-displaying area is extended between screens of the electronic device and external electronic device, may be changed based on a location of the electronic device relative to the external electronic device. According to the above-described examples, the display settings may be changed automatically without the need for a user to provide an input to the electronic device to change the display settings when the electronic device is moved or placed at a location relative to the external electronic device which is different from a location that is assumed by an operating system of the electronic device. Therefore, user convenience may be improved, and a reduction in technical support requests may be achieved. Furthermore, the examples described herein provide real-time and accurate location information of the electronic device based on location information being obtained via UWB ranging messages exchanged between the electronic device and the external electronic device.

[0089] Executable instructions to perform processes or operations in accordance with the above-described examples may be recorded in a computer readable storage medium. A processor may execute the executable instructions to perform the processes or operations. Examples of instructions include both machine code, such as that produced by a compiler, and files containing higher level code that may be executed by the controller using an interpreter. The computer readable storage medium may be distributed among computer systems connected through a network and computer-readable codes or instructions may be stored and executed in a decentralized manner.

[0090] Each block of the flowchart illustrations may represent a module, segment, or portion of code, which comprises one or more executable instructions for implementing the specified logical function(s). In some examples, the functions noted in the blocks may occur out of order. For example, two blocks shown in succession may be executed substantially concurrently (simultaneously) or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved.

[0091] When it is stated in the disclosure that one element is "connected to" another element, the expression encompasses an example of a direct connection or direct coupling, as well as a connection with another element interposed therebetween. Further, when it is stated herein that one element "includes" another element, unless otherwise stated explicitly, it means that yet another element may be further included rather than being excluded.

[0092] The foregoing examples are merely examples and are not to be construed as limiting the disclosure. The disclosure may be readily applied to other types of apparatuses. Various modifications may be made which are also intended to be encompassed by the disclosure. Also, the description of the examples of the disclosure is intended to be illustrative, and not to limit the scope of the claims.
