The external electronic device (50) may be a user terminal (e.g., a wearable device such as a smartphone or a smartwatch) connected to the first ring electronic device (10) and the second ring electronic device (20) by wireless communication. FIGS. 5A, 5B, and 5C illustrate embodiments that provide an integrated projection screen when a user wears the first ring electronic device (10) and the second ring electronic device (20).

[0132] According to one embodiment, the above-described content regarding the first ring electronic device (10) may be similarly applied to the second ring electronic device (20). In the present disclosure, for convenience of explanation, elements associated with the first ring electronic device (10) (e.g., projection screen, partial screen, etc.) and elements associated with the second ring electronic device (20) are respectively described as 'first -' and 'second -'.

[0133] As described with reference to FIGS. 3 and 4, the second ring electronic device (20) can determine the wearing state of the second ring electronic device (20). The second ring electronic device (20) can identify that the second ring electronic device is worn on the user's finger based on data received from the sensor circuit. While the second ring electronic device (20) is worn on the user's finger, the second ring electronic device (20) can detect motion using a camera. The second ring electronic device (20) can determine whether at least a portion of the first trigger motion with respect to the projection screen is detected. The second ring electronic device (20) can control the projection circuit to output a second projection screen based on the detection of at least a portion of the first trigger motion with respect to the projection screen.

Any description of the second ring electronic device (20) that overlaps with the description of the first ring electronic device (10) described above will be omitted.

[0134] According to one embodiment, FIG. 5a is described.

[0135] In operation 510-1, the first ring electronic device (10) can control the projection circuit to output a first projection screen. For example, operation 510-1 may be operation 330 of outputting the first projection screen of FIG. 3.

[0138] According to one embodiment, information about the output status of the second projection screen may include information about whether the second ring electronic device (20) outputs the second projection screen. For example, when the second ring electronic device (20) outputs the second projection screen based on detecting at least a portion of the first trigger motion, the second ring electronic device (20) may transmit information about outputting the second projection screen to the first ring electronic device (10).

[0139] According to one embodiment, information about the output status of the second projection screen may further include information about a user interface corresponding to the second projection screen. For example, information about the output status of the second projection screen may include information about whether the second projection screen is a home screen or information about an application corresponding to the execution screen displayed by the second projection screen (i.e., an application being executed by the second ring electronic device (20).

[0140] According to one embodiment, the first projection screen and the second projection screen may be output in any order. That is, operations 510-1 and 520-1 may be performed in any order. For example, operation 520-1 may be performed after operation 510-1. For example, operation 510-1 may be performed after operation 520-1. Accordingly, although operation 530-1 is illustrated as being performed after operation 510-1, if the second projection screen is output before the first projection screen, operation 530-1 may be performed before operation 510-1.

[0141] According to one embodiment, the second ring electronic device (20) can perform operation 530-1 at regular time intervals.

According to one embodiment, when the output status of the second projection screen changes, the second ring electronic device (20) can transmit information about the output status of the second projection screen to the first ring electronic device (10). For example, the second ring electronic device (20) can transmit information about the output status of the second projection screen to the first ring electronic device (10) when the output of the second projection screen starts, the output of the second projection screen stops, or the execution screen indicated by the second projection screen changes (e.g., the execution status of an application changes).

The integrated projection screen may include a plurality of partial screens.

[0144] In one embodiment, when a user wears multiple ring electronic devices, each of the multiple ring electronic devices can independently output a projection screen. The projection angle, direction, or size of each projection screen can be set according to the settings of each individual ring electronic device. Alternatively, the integrated projection screen can include multiple sub-screens arranged sequentially. Preferably, the multiple sub-screens can be arranged without any empty space.

[0145] In one embodiment, each sub-screen of the integrated projection screen may display individual content of the ring electronic device that outputs the respective sub-screen. That is, each sub-screen may be an independent user interface.

That is, each partial screen may be a different part of an extended user interface corresponding to the same content. For example, the partial screens of the integrated projection screen may display content of a specific ring electronic device or content of an external electronic device (e.g., an external electronic device (50)) connected to a plurality of ring electronic devices. The first partial screen and the second partial screen of the first ring electronic device (10) and the second ring electronic device (20) are described below.

According to one embodiment, the first ring electronic device (10) can determine that the motion detected by the first electronic device (10) and / or the motion detected by the second ring electronic device (20) includes at least a portion of the second trigger motion. Referring to FIG. 6, the user can pinch in a direction in which any point on the first projection screen (601) of the first hand wearing the first ring electronic device (10) and the second ring electronic device (20) and any point on the second projection screen (602) are brought closer to each other with the fingers of the second hand not wearing the first ring electronic device (10) and the second ring electronic device (20).

[0204] According to one embodiment, the first ring electronic device (10) can generate a first partial screen (6010) for the integrated projection screen (6100) based on detecting at least a portion of the second trigger motion and transmit a request signal for the integrated projection screen to the second ring electronic device (20). The second ring electronic device (20) can generate a second partial screen (6020) for the integrated projection screen (6100) based on the request signal for the integrated projection screen.

[0205] In state (630), the first ring electronic device (10) can control the projection circuit to output the first partial screen (6010) for the integrated projection screen (6100) as the first projection screen (601). That is, the first ring electronic device (10) can output the first partial screen (6010) by replacing the first projection screen (601). The second ring electronic device (20) can control the projection circuit to output the second partial screen (6020) for the integrated projection screen (6100) as the second projection screen (602). That is, the second ring electronic device (20) can output the second partial screen (6020) by replacing the second projection screen (602).

[0206] According to one embodiment, referring to FIG. 6, an integrated projection screen (6100) may include a first partial screen (6010) and a second partial screen (6020). The integrated projection screen (6100) may include the first partial screen (6010) and the second partial screen (6020) arranged sequentially. Preferably, the first partial screen (6010) and the second partial screen (6020) may be arranged without any blank space.

[0207] Below, the integrated projection screen (6100) and various methods for configuring the same are described.

[0208] According to one embodiment, the first partial screen (6010) and the second partial screen (6020) of the integrated projection screen (6100) may respectively display individual contents of the first ring electronic device (10) and the second ring electronic device (20). That is, the first partial screen (6010) and the second partial screen (6020) may be independent user interfaces. The integrated projection screen (6100) may be composed of the first partial screen (6010) including the contents displayed by the first projection screen (601) as is and the second partial screen (6020) including the contents displayed by the second projection screen (602) as is.

[0209] For example, if a second trigger motion for the integrated projection screen is detected while the first projection screen (601) and the second projection screen (602) are output as independent user interfaces, a first partial screen (6010) for a user interface corresponding to the content of the first ring electronic device (10) and a second partial screen (6020) for a user interface corresponding to the content of the second ring electronic device (20) may be output as the first projection screen (601) and the second projection screen (602), respectively. The first ring electronic device (10) may generate and output the first partial screen (6010) for the user interface corresponding to the content of the first ring electronic device (10) based on detecting at least a portion of the second trigger motion, and transmit a request signal for the integrated projection screen to the second ring electronic device (20). The second ring electronic device (20) can generate and output a second partial screen (6020) for a user interface corresponding to the content of the second ring electronic device (20) based on a request signal for the integrated projection screen.

[0210] According to one embodiment, different portions of an integrated projection screen (6100) for an extended user interface corresponding to the same content may be output as a first partial screen (6010) and a second partial screen (6020). That is, the first partial screen (6010) and the second partial screen (6020) may constitute an integrated interface.

[0211] For example, when a third trigger motion for expanding the user interface for the first partial screen (6010) is detected while the first partial screen (6010) and the second partial screen (6020) are output as independent user interfaces, a screen for an expanded user interface corresponding to the content of the first ring electronic device (10) may be generated. The first and second parts of the screen for the expanded user interface may be output as the first partial screen (6010) and the second partial screen (6020), respectively.

[0212] For example, when a third trigger motion for expanding the user interface for the second partial screen (6020) is detected while the first partial screen (6010) and the second partial screen (6020) are output as independent user interfaces, a screen for an expanded user interface corresponding to the content of the second ring electronic device (20) may be generated. The first and second parts of the screen for the expanded user interface may be output as the first partial screen (6010) and the second partial screen (6020), respectively. An operation for providing partial screens by the third trigger motion is described in detail with reference to FIG. 7.

[0213] For example, if a second trigger motion is detected on the integrated projection screen while any ring electronic device is outputting a projection screen for a user interface corresponding to a home screen (simply, a projection screen representing a home screen), a first portion and a second portion of the screen for an extended user interface corresponding to the contents of another ring electronic device running any application may be output as a first partial screen (6010) and a second partial screen (6020), respectively. That is, a ring electronic device that is not running any application may be excluded when configuring the integrated projection screen (6100).

[0214] Hereinafter, a case in which the second ring electronic device (20) outputs a second projection screen (602) indicating a home screen will be described.

[0215] A first ring electronic device (10) may output a first projection screen (601) representing an execution screen of a first application, and a second ring electronic device (20) may output a second projection screen (602) representing a home screen. As described above with reference to FIG. 5A, the first ring electronic device (10) may receive information about an output status of the second projection screen from the second ring electronic device (20). The information about the output status of the second projection screen may include whether the second projection screen is a home screen. The first ring electronic device (10) may transmit a request signal for an integrated projection screen to the second ring electronic device (20) based on detecting a second trigger motion. The request signal for the integrated projection screen may include a request, a command, or a control signal for starting the integrated projection screen.

[0216] According to an embodiment, a request signal for an integrated projection screen may further include any portion of a screen for an extended user interface. The first ring electronic device (10) may generate a screen by rendering a video signal for an extended user interface corresponding to the content of the first ring electronic device (10), i.e., an execution screen of a first application. The first ring electronic device (10) may split the screen for the extended user interface into a part thereof and another part to generate a first portion and a second portion. The first ring electronic device (10) may consider the number of other connected ring electronic devices when splitting the screen for the extended user interface. The first ring electronic device (10) may transmit a request signal for an integrated projection screen including the second portion to the second ring electronic device (20). The first ring electronic device (10) may control a projection circuit to output the first portion as a first partial screen (6010). The second ring electronic device (20) may control a projection circuit to output the second portion as a second partial screen (6020).

[0217] According to an embodiment, the request signal for the integrated projection screen may further include a video signal (e.g., a digital signal) of any portion of the screen for the extended user interface. The first ring electronic device (10) may generate a video signal of the first portion and a video signal of the second portion of the screen for the extended user interface corresponding to the content of the first ring electronic device (10). The first ring electronic device (10) may render the video signal of the first portion using a projection circuit to generate the first portion. The first ring electronic device (10) may transmit a request signal for the integrated projection screen including the video signal of the second portion to the second ring electronic device (20). The second ring electronic device (20) may render the video signal of the second portion based on the request signal for the integrated projection screen to generate the second portion. The first ring electronic device (10) may control the projection circuit to output the first portion as the first portion screen (6010). The second ring electronic device (20) can control the projection circuit to output the second portion as a second portion screen (6020).

[0218] Hereinafter, a case in which the first ring electronic device (10) outputs the first projection screen (601) indicating the home screen will be described.

[0219] A first ring electronic device (10) can output a first projection screen (601) representing a home screen, and a second ring electronic device (20) can output a second projection screen (602) representing an execution screen of a second application. Based on detecting a second trigger motion, the first ring electronic device (10) can transmit a request signal for an integrated projection screen to the second ring electronic device (20).

[0220] The first ring electronic device (10) can transmit information about the output status of the first projection screen to the second ring electronic device (20). For example, the first ring electronic device (10) can transmit information about the output status of the first projection screen to the second ring electronic device (20) as part of a request signal for an integrated projection screen. The information about the output status of the first projection screen can include whether the first projection screen is a home screen. For example, the first ring electronic device (10) can transmit information about the output status of the first projection screen to the second ring electronic device (20) similar to operation 530-1 of FIG. 5A in which the second ring electronic device (20) transmits information about the output status of the second projection screen to the first ring electronic device (10).

[0221] According to an embodiment, the second ring electronic device (20) may generate a screen for an extended user interface corresponding to the content of the second ring electronic device (20), i.e., an execution screen of the second application, based on a request signal for an integrated projection screen and information about an output status of the first projection screen. The second ring electronic device (20) may generate a screen by rendering a video signal for the extended user interface. The second ring electronic device (20) may divide the screen for the extended user interface into a part thereof and another part thereof to generate a first part and a second part. The second ring electronic device (20) may transmit information about the first part to the first ring electronic device (10). The first ring electronic device (10) may control a projection circuit to output the first part as a first partial screen (6010). The second ring electronic device (20) may control a projection circuit to output the second part as a second partial screen (6020).

[0222] According to an embodiment, the second ring electronic device (20) may generate a video signal of a first portion and a video signal of a second portion of a screen for an extended user interface corresponding to the content of the second ring electronic device (20) based on a request signal for an integrated projection screen and information about an output status of the first projection screen. The second ring electronic device (20) may render the video signal of the second portion using a projection circuit to generate the second portion. The second ring electronic device (20) may transmit information about the video signal of the first portion to the first ring electronic device (10). The first ring electronic device (10) may render the video signal of the first portion to generate the first portion. The first ring electronic device (10) may control the projection circuit to output the first portion as a first portion screen (6010). The second ring electronic device (20) may control the projection circuit to output the second portion as a second portion screen (6020).

[0223] For example, if a second trigger motion is detected on the integrated projection screen while multiple ring electronic devices are outputting projection screens for user interfaces corresponding to the home screen, the first and second portions of the screen for the extended user interface of the home screen may be output as the first partial screen (6010) and the second partial screen (6020), respectively.

[0224] For example, if a second trigger motion is detected for the integrated projection screen while the first projection screen (601) and the second projection screen (602) are output as independent user interfaces, a screen for an extended user interface corresponding to the content of the main ring electronic device may be generated. The first and second parts of the screen for the extended user interface may be output as a first partial screen (6010) and a second partial screen (6020), respectively. That is, ring electronic devices other than the main ring electronic device (hereinafter, referred to as auxiliary ring electronic devices) may be excluded when configuring the integrated projection screen (6100). According to an embodiment, if a second trigger motion is detected while the auxiliary ring electronic device is executing an application, the execution of the application may be stopped or executed in the background. One of the plurality of ring electronic devices may be set as the main ring electronic device. The main ring electronic device may be selected or changed by the user.

[0225] Hereinafter, a description will be given of a case where the first ring electronic device (10) is the main ring electronic device.

[0226] A first ring electronic device (10) can output a first projection screen (601) representing an execution screen of a first application, and a second ring electronic device (20) can output a second projection screen (602) representing an execution screen of a second application. Based on detecting a second trigger motion, the first ring electronic device (10) can transmit a request signal for an integrated projection screen to the second ring electronic device (20). The request signal for the integrated projection screen can include a request, a command, or a control signal for starting the integrated projection screen.

[0227] According to an embodiment, a request signal for an integrated projection screen may further include any portion of a screen for an extended user interface. The first ring electronic device (10) may generate a screen by rendering a video signal for an extended user interface corresponding to an execution screen of a first application. The first ring electronic device (10) may divide the screen for the extended user interface into a part thereof and another part thereof to generate a first portion and a second portion. The first ring electronic device (10) may transmit a request signal for an integrated projection screen including the second portion to the second ring electronic device (20).

[0228] According to an embodiment, the request signal for the integrated projection screen may further include a video signal of any portion of the screen for the extended user interface. The first ring electronic device (10) may generate a video signal of the first portion and a video signal of the second portion of the screen for the extended user interface corresponding to the content of the first ring electronic device (10). The first ring electronic device (10) may render the video signal of the first portion using a projection circuit to generate the first portion. The first ring electronic device (10) may transmit a request signal for the integrated projection screen including the video signal of the second portion to the second ring electronic device (20). The second ring electronic device (20) may render the video signal of the second portion based on the request signal for the integrated projection screen to generate the second portion.

[0229] The second ring electronic device (20) can respond to a request signal for the integrated projection screen by suspending execution of the second application or executing it in the background.

[0230] Below, a method for providing battery status of ring electronic devices is described.

[0231] In state (610) of FIG. 6, the first ring electronic device (10) and the second ring electronic device (20) can independently output a first projection screen (601) and a second projection screen (602), respectively. The first projection screen (601) and the second projection screen (602) can include the battery status of the first ring electronic device (10) and the battery status of the second ring electronic device (20), respectively.

[0232] In state (630) of FIG. 6, the first ring electronic device (10) and the second ring electronic device (20) can output a first partial screen (6010) and a second partial screen (6020) for an integrated projection screen (6100).

[0233] According to one embodiment, the first partial screen (6010) and the second partial screen (6020) may each represent individual contents of the first ring electronic device (10) and the second ring electronic device (20). That is, the first partial screen (6010) and the second partial screen (6020) may be independent user interfaces. The first partial screen (6010) and the second partial screen (6020) may each include a battery status of the first ring electronic device (10) and a battery status of the second ring electronic device (20).

[0234] According to one embodiment, different parts of an integrated projection screen (6100) for an extended user interface corresponding to the same content may be output as a first partial screen (6010) and a second partial screen (6020). That is, the first partial screen (6010) and the second partial screen (6020) may constitute an integrated interface. The integrated projection screen (6100) may include the respective battery states of the first ring electronic device (10) and the second ring electronic device (20) together in one partial screen. For example, as illustrated in FIG. 6, the respective battery states of the first ring electronic device (10) and the second ring electronic device (20) may be included together in a partial screen (e.g., the first partial screen (6010)) located at the top from the viewpoint of a user wearing the first ring electronic device (10) and the second ring electronic device (20).

[0235] FIG. 7 is a drawing for explaining an operation of providing a split screen according to one embodiment.

[0236] FIG. 7 illustrates states (710 to 730) in which a first ring electronic device (10) (e.g., the electronic device (102) of FIG. 1 or the electronic device (200) of FIG. 2) and a second ring electronic device (20) (e.g., the electronic device (102) of FIG. 1 or the electronic device (200) of FIG. 2) are worn by a user. The first ring electronic device (10) and the second ring electronic device (20) may each include at least some of the components of the ring electronic device (200) described in FIG. 2. For example, the first ring electronic device (10) and the second ring electronic device (20) may include at least one processor (e.g., the processor (210) of FIG. 2), a memory (e.g., the memory (220) of FIG. 2), a communication unit (e.g., the communication unit (230) of FIG. 2), a camera (e.g., the camera (11) of FIG. 4), a sensor circuit, and a projection circuit.

[0237] According to one embodiment, the first ring electronic device (10) can continuously detect motion using a camera while being worn on the user's finger (4).

The second ring electronic device (20) can output a second partial screen (702) for a user interface corresponding to the content of the second ring electronic device (20). For example, the first ring electronic device (10) can output a first partial screen (701) for a user interface corresponding to an execution screen of a first application. The second ring electronic device (20) can output a second partial screen (702) for a user interface corresponding to the execution screen of the second application.

[0239] According to one embodiment, the first ring electronic device (10) may generate a screen for an extended user interface corresponding to the content of the first ring electronic device (10) based on detecting at least a portion of a third trigger motion for extending the user interface while the first partial screen (701) for the integrated projection screen (7100) is output.

[0240] According to one embodiment, the third trigger motion for expanding the user interface may be a motion configured to trigger, initiate, or start outputting an expanded user interface corresponding to the same content for a plurality of ring electronic devices (e.g., a first ring electronic device (10) and a second ring electronic device (20)). The third trigger motion may be preset or changed by a user.

[0241] According to one embodiment, the third trigger motion may be a motion in which a second hand, on which the first ring electronic device (10) and the second ring electronic device (20) are not worn, swipes from any point in one partial screen of the first hand, on which the first ring electronic device (10) and the second ring electronic device (20) are worn, to any point in another partial screen. For example, the third trigger motion for the first partial screen (701) may be a motion in which a swipe is made from any point in the first partial screen (701) to any point in another partial screen (e.g., the second partial screen (702)). For example, the third trigger motion for the second partial screen (702) may be a motion in which a swipe is made from any point in the second partial screen (702) to any point in another partial screen (e.g., the first partial screen (701)).

[0242] In one embodiment, the third trigger motion may be a motion in which the second hand spreads (or pinches to zoom) over any portion of the screen of the first hand. For example, the third trigger motion for the first portion of the screen (701) may be a motion in which the fingers of the second hand spread over the first portion of the screen (701).

[0243] In state (710), the first ring electronic device (10) can generate a screen for an extended user interface corresponding to the content of the first ring electronic device (10) based on detecting at least a portion of a swiping motion from any point of the first partial screen (701) to any point of the second partial screen (702) while the first partial screen (701) for the integrated projection screen (7100) is being output.

The near side (93) may represent a side that is relatively close to the ring electronic device (9), and the far side (94) may represent a side that is relatively far from the ring electronic device (9).

[0261] According to one embodiment, the ring electronic device (9) can control the projection circuit to adjust the length of at least one of the left side (91), the right side (92), the near side (93), or the far side (94) of the screen (90).

[0262] For example, referring to (a) of FIG. 9, the length of the screen (90) between the near side (93) and the far side (94) of the screen (90) can be adjusted. Depending on the embodiment, the lengths of the left side (91) and the right side (92) can be adjusted differently to correct distortion of the output screen (90).

[0263] For example, the width (or length of the width) of the screen (90) between the left side (91) and the right side (92) of the screen (90) can be adjusted. Depending on the embodiment, the lengths of the near side (93) and the far side (94) can be adjusted differently to correct distortion of the output screen (90).

[0264] According to one embodiment, the ring electronic device (9) can control the projection circuit to adjust the position of the screen (90). Referring to (b) of FIG. 9, the relative position of the screen (90) with respect to a point corresponding to the optical axis through which the screen (90) is output (or projected) through a projection lens (e.g., the projection lens (15) of FIG. 4) can be adjusted. At least some of the distances from each side of the screen (90) to the point corresponding to the optical axis can be changed. For example, when the position of the screen (90) is adjusted in a direction away from the ring electronic device (9), the distances from the left side (91) and the right side (92) to the point corresponding to the optical axis can be maintained.

[0265] According to one embodiment, the ring electronic device (9) can control the projection circuit to adjust the rotation angle of the screen (90). Referring to (c) of FIG. 9, the screen (90) can be rotated clockwise or counterclockwise with respect to a point corresponding to the optical axis from which the screen (90) is output. Each distance from each side of the screen (90) to a point corresponding to the optical axis can be maintained.

[0266] FIG. 10 is a drawing for explaining an operation of aligning a projection screen according to one embodiment.

[0267] FIG. 10 illustrates states (910 to 930) in which a first ring electronic device (10) (e.g., the electronic device (102) of FIG. 1 or the ring electronic device (200) of FIG. 2) and a second ring electronic device (20) (e.g., the electronic device (102) of FIG. 1 or the ring electronic device (200) of FIG. 2) are worn by a user. The first ring electronic device (10) and the second ring electronic device (20) may each include at least some of the components of the ring electronic device (200) described in FIG. 2. For example, the first ring electronic device (10) and the second ring electronic device (20) may include at least one processor (e.g., the processor (210) of FIG. 2), a memory (e.g., the memory (220) of FIG. 2), a communication unit (e.g., the communication unit (230) of FIG. 2), a camera (e.g., the camera (11) of FIG. 4), a sensor circuit, and a projection circuit.

[0268] According to one embodiment, the first ring electronic device (10) can continue to detect motion using a camera while being worn on the user's finger (4). The second ring electronic device (20) can continue to detect motion using a camera while being worn on the user's finger (5).

[0269] In state (1010), the first ring electronic device (10) can output a screen (1001). The second ring electronic device (20) can output a screen (1002). Depending on the embodiment, the screen (1001) can be one of the first projection screen described above or a first partial screen for an integrated projection screen. The screen (1002) can be one of the second projection screen described above or a second partial screen for an integrated projection screen.

[0270] According to one embodiment, the screen (1001) and the screen (1002) may each include a left side, a right side, a near side, and a far side.

[0271] According to one embodiment, the state (1010) may be a misaligned state where the sizes (or lengths) of the screen (1001) and / or the screen (1002) do not match.

[0272] According to one embodiment, the state (1010) may be a misaligned state in which the positions at which the screen (1001) and the screen (1002) are output (e.g., the position of the near side of the screen (1001) and / or the screen (1002)) do not match.

[0273] According to one embodiment, the state (1010) may be a state in which the direction or angle at which the screen (1001) and / or the screen (1002) are output do not match, as illustrated in FIG. 10, and thus are not aligned.

[0274] In state (1020), the first ring electronic device (10) can detect at least a portion of the alignment motion for the screen (1001) and the screen (1002) using data received from the camera while the screen (1001) and the screen (1002) (e.g., the first projection screen and the second projection screen) are being output.

[0275] According to one embodiment, the alignment motion may be a motion in which a second hand of a user, on which the first ring electronic device (10) and the second ring electronic device (20) are not worn, points to an alignment line on the first hand on which the first ring electronic device (10) and the second ring electronic device (20) are worn. For example, the alignment motion may be a motion in which the second hand is placed on the first hand and maintained for a certain period of time (e.g., 1 to 2 seconds) such that an extended finger (e.g., a single finger or multiple fingers) of the second hand points toward a desired alignment line. For example, the alignment motion may be a motion in which the second hand is placed on the first hand and maintained for a certain period of time such that an edge of the second hand points toward a desired alignment line.

[0276] According to one embodiment, the first ring electronic device (10) can measure the distance from the first ring electronic device (10) (or the camera of the first ring electronic device (10)) to the user's second hand or a finger of the second hand (hereinafter, referred to as the second hand) using the camera (or sensor) described above in FIG. 2. The first ring electronic device (10) can continuously monitor the distance to the second hand using the camera.

[0277] According to one embodiment, the first ring electronic device (10) can detect an alignment motion based on a distance to the second hand. For example, the first ring electronic device (10) can detect an alignment motion when a state in which the distance from the first ring electronic device (10) to the second hand is measured to be within a specified distance (e.g., the length of the screen (1001)) or an error range of the specified distance is maintained for a certain period of time.

[0278] According to one embodiment, the first ring electronic device (10) may receive information about a motion detected by using the camera of the second ring electronic device (20) from the second ring electronic device (20). The first ring electronic device (10) may receive information about a distance from the second ring electronic device (20) (or the camera of the second ring electronic device (20)) to the user's second hand or a finger of the second hand (hereinafter, referred to as the second hand). The first ring electronic device (10) may detect an alignment motion when the distance from the first ring electronic device (10) to the second hand matches the distance from the second ring electronic device (20) to the second hand. For example, the first ring electronic device (10) can detect an alignment motion when a state in which the distance from the first ring electronic device (10) to the second hand and the distance from the second ring electronic device (20) to the second hand are equal and measured within a specified distance or an error range of the specified distance is maintained for a certain period of time.

[0279] In state (1030), the first ring electronic device (10) can control the projection circuit to adjust the output of the screen (1001) based on detecting at least a portion of the alignment motion for the screen (1001) and the screen (1002). For example, as described above in FIG. 2, the first ring electronic device (10) can control the projection circuit to perform functions such as zoom, keystone, and lens shift.

[0280] According to one embodiment, the first ring electronic device (10) can control the projection circuit to adjust the length of the screen (1001) between the near side and the far side of the screen (1001) so that the far side of the screen (1001) reaches an alignment line indicated by the alignment motion.

[0281] According to one embodiment, the first ring electronic device (10) can control the projection circuit to adjust the position of the screen (1001) so that the far side of the screen (1001) reaches the alignment line indicated by the alignment motion.

[0282] According to one embodiment, the first ring electronic device (10) can control the projection circuit to adjust the rotation angle of the screen (1001) so that the far side of the screen (1001) reaches the alignment line indicated by the alignment motion.

[0283] According to one embodiment, the first ring electronic device (10) can transmit an alignment request signal of the screen (1002) to the second ring electronic device (20). For example, as described above with reference to FIG. 2, the second ring electronic device (20) can control the projection circuit to perform functions such as zoom, keystone, and lens shift using the projection circuit. The second ring electronic device (20) can control the projection circuit to adjust the output of the screen (1002) based on the alignment request signal.

[0284] According to an embodiment, in state (1010), the first ring electronic device (10) can determine the alignment state of the screen (1001) and the screen (1002). For example, the first ring electronic device (10) can monitor the alignment state of the screen (1001) and the screen (1002) using a camera. According to an embodiment, the first ring electronic device (10) can control the projection circuit to perform functions such as zoom, keystone, and lens shift without detecting the alignment motion (i.e., omitting state (920)). The first ring electronic device (10) can also transmit an alignment request signal of the screen (1002) to the second ring electronic device (20).

[0285] FIGS. 11A and 11B are drawings for explaining an operation of adjusting the output of a projection screen according to one embodiment.

[0286] FIGS. 11A and 11B illustrate states (1011 to 1041, 1112 to 1142) in which a first ring electronic device (10) (e.g., the electronic device (102) of FIG. 1 or the ring electronic device (200) of FIG. 2) is worn by a user. The first ring electronic device (10) may include at least some of the components of the ring electronic device (200) described in FIG. 2. For example, the first ring electronic device (10) may include at least one processor (e.g., the processor (210) of FIG. 2), a memory (e.g., the memory (220) of FIG. 2), a communication unit (e.g., the communication unit (230) of FIG. 2), a camera (e.g., the camera (11) of FIG. 4), a sensor circuit, and a projection circuit.

[0287] According to one embodiment, the first ring electronic device (10) can continue to detect motion using a camera while being worn on the user's finger (4).

[0288] FIG. 11a is a drawing for explaining an operation of adjusting the position of a screen (1001) output by the first ring electronic device (10).

[0289] In state (1111), the first ring electronic device (10) can output a screen (1001). Depending on the embodiment, the screen (1101) can be one of the first projection screen described above or a first partial screen for an integrated projection screen.

[0290] According to one embodiment, the state (1111) may be a state in which the screen (1101) is not output in an appropriate location, as illustrated in FIG. 11a.

[0291] In state (1121), the first ring electronic device (10) can detect at least a portion of an adjustment motion for the screen (1101) using data received from the camera while the screen (1101) is being output. For example, the first ring electronic device (10) can detect at least a portion of a press-and-hold motion of a single finger (e.g., a single finger of a second hand on which the first ring electronic device (10) is not being worn). The first ring electronic device (10) can detect a motion in which a single finger touches any point on the screen (1001) and holds it therefor for a certain period of time (e.g., 1 to 3 seconds).

[0292] In state (1131), the first ring electronic device (10) may activate an adjustment state of the screen (1101) based on detecting a press-and-hold motion of a single finger on the screen (1101). For example, the first ring electronic device (10) may output a screen (1001) including a message instructing to adjust the position of the screen (1101).

[0293] In state (1141), the first ring electronic device (10) can control the projection circuit to adjust the position of the screen (1101) based on the user's motion detected while the adjustment state is activated. Specifically, the position of the screen (1001) can be moved based on the direction of the motion of a single finger of the second hand.

[0294] FIG. 11b is a drawing for explaining an operation of adjusting the rotation angle of a screen (1101) output by the first ring electronic device (10).

[0295] In state (1112), the first ring electronic device (10) can output a screen (1101). Depending on the embodiment, the screen (1101) can be one of the first projection screen described above or a first partial screen for an integrated projection screen.

[0296] According to one embodiment, state (1112) may be a state in which the screen (1101) is not output at an appropriate angle, as illustrated in FIG. 11b.

[0297] In state (1122), the first ring electronic device (10) can detect at least a portion of an adjustment motion for the screen (1101) using data received from the camera while the screen (1101) is being output. For example, the first ring electronic device (10) can detect at least a portion of a press-and-hold motion of multiple fingers (e.g., multiple fingers of a second hand on which the first ring electronic device (10) is not worn). The first ring electronic device (10) can detect a motion in which multiple fingers touch any point on the screen (1101) and hold it for a certain period of time (e.g., 1 to 3 seconds).

[0298] In state (1132), the first ring electronic device (10) may activate an adjustment state of the screen (1101) based on detecting a press-and-hold motion of multiple fingers on the screen (1101). For example, the first ring electronic device (10) may output a screen (1101) including a message instructing to adjust the angle of the screen (1101).

[0299] In state (1142), the first ring electronic device (10) can control the projection circuit to adjust the rotation angle of the screen (1101) based on the user's motion detected while the adjustment state is activated. Specifically, the rotation angle of the screen (1101) can be adjusted based on the direction of the motion of the multiple fingers of the second hand.

[0300] The correspondence between the adjustment motions described in FIGS. 11A and 11B and the adjustment states for adjusting the position or rotation angle of the screen (1101) is not limited to the present disclosure. For example, the rotation angle of a screen may be adjusted based on detection of a press-and-hold motion of a single finger on an arbitrary screen, or the position of the screen may be adjusted based on detection of a press-and-hold motion of multiple fingers. For example, the type of the detected adjustment motion (press-and-hold motion of a single finger or multiple fingers) and the type of the object to be adjusted while the adjustment state is activated in response thereto may be changed by a user setting or implemented in various ways by a manufacturer setting.

[0301] FIG. 12 is a drawing for explaining an operation of stopping output of a projection screen according to one embodiment.

[0302] FIG. 12 illustrates states (1210 to 1250) in which a first ring electronic device (10) (e.g., the electronic device (102) of FIG. 1 or the ring electronic device (200) of FIG. 2) and a second ring electronic device (20) (e.g., the electronic device (102) of FIG. 1 or the ring electronic device (200) of FIG. 2) are worn by a user. The first ring electronic device (10) and the second ring electronic device (20) may include at least some of the components of the ring electronic device (200) described in FIG. 2. For example, the first ring electronic device (10) and the second ring electronic device (20) may include at least one processor (e.g., the processor (210) of FIG. 2), a memory (e.g., the memory (220) of FIG. 2), a communication unit (e.g., the communication unit (230) of FIG. 2), a camera (e.g., the camera (11) of FIG. 4), a sensor circuit, and a projection circuit.

[0303] According to one embodiment, the first ring electronic device (10) can continue to detect motion using a camera while being worn on the user's finger (4). The second ring electronic device (20) can continue to detect motion using a camera while being worn on the user's finger (5).

[0304] In states (1210, 1250), the first ring electronic device (10) can output a screen (1201). The second ring electronic device (20) can output a screen (1202). Depending on the embodiment, the screen (1201) can be one of the first projection screen described above or a first partial screen for an integrated projection screen. The screen (1202) can be one of the second projection screen described above or a second partial screen for an integrated projection screen.

[0305] In state (1210), the second ring electronic device (20) can detect at least a portion of a shut-down motion for the screen (1202) using data received from a camera (or sensor) while the screen (1202) is being output.

[0306] In one embodiment, the shutdown motion may be a motion of touching (or pressing) and holding the ring electronic device with a second hand that is not wearing the ring electronic device (e.g., first ring electronic device (10), second ring electronic device (20)).

[0307] In one embodiment, the shutdown motion may be a motion in which the user's body or any object covers or blocks the output of the screen (e.g., screen (1201), screen (1202)) of the ring electronic device.

[0308] In one embodiment, the shutdown motion may be a motion of the first hand wearing the ring electronic device making a fist.

[0309] In one embodiment, the shutdown motion may be any motion that leaves the first hand in a state where normal screen output or the user's screen viewing is impossible. For example, the shutdown motion may be a motion such as putting the first hand in a pocket, lowering the first hand in the direction of gravity acceleration, or touching the floor with the first hand.

[0310] In state (1220), the second ring electronic device (20) may control the projection circuit to stop outputting the screen (1202) based on detecting at least a portion of a shutdown motion for the screen (1202). In an embodiment, when the screens (1201, 1202) are output as partial screens for an integrated projection screen in state (1210), the provision of the integrated projection screen may be terminated by stopping outputting the screen (1202). In an embodiment, the first ring electronic device (10) may generate a new screen (1201) and output the new screen (1201) in state (1220). For example, the first ring electronic device (10) may generate and output a screen (1201) for a user interface corresponding to an execution screen of an application that was running in state (1210). For example, the first ring electronic device (10) can generate and output a screen (1201) for a user interface corresponding to a home screen.

[0311] In state (1230), the first ring electronic device (10) can detect at least a portion of a shutdown motion for the screen (1201) using data received from the camera while the screen (1201) is being output.

[0312] In state (1240), the first ring electronic device (10) can control the projection circuit to stop outputting the screen (1201) based on detecting at least a portion of the shutdown motion for the screen (1201) in state (1230).

[0313] In state (1250), the first ring electronic device (10) can detect a shutdown motion for the screen (1201) and the screen (1202) using data received from the camera while the screen (1201) and the screen (1202) are output. Additionally or alternatively, the second ring electronic device (20) can detect a shutdown motion for the screen (1202) using data received from the camera while the screen (1201) and the screen (1202) are output.

[0314] According to one embodiment, the first ring electronic device (10) can receive information about a motion detected by the camera of the second ring electronic device (20) from the second ring electronic device (20). The first ring electronic device (10) can detect a shutdown motion for the screen (1201) and the screen (1202) based on the information about the motion detected by the first ring electronic device (10) and the motion received from the second ring electronic device (20).

[0315] In state (1240), the first ring electronic device (10) may control the projection circuit to stop outputting the screen (1201) based on detecting at least a portion of a shutdown motion for the screen (1201) and the screen (1202) in state (1250). According to an embodiment, the first ring electronic device (10) may transmit a request signal to stop outputting the screen (1202) to the second ring electronic device (20), and the second ring electronic device (20) may control the projection circuit to stop outputting the screen (1202) based on the request signal. That is, the second ring electronic device (20) may stop outputting the screen (1202) based on directly detecting a shutdown motion for the screen (1202) or based on the request signal to stop outputting the screen (1202) according to an embodiment.

[0316] According to one embodiment, the first ring electronic device (10) can stop outputting the screen (1201) in various cases. According to the embodiment, the first ring electronic device (10) can control the projection circuit to stop outputting the screen (1201) when a predetermined state condition is satisfied.

[0317] For example, the first ring electronic device (10) can control the projection circuit to stop outputting the screen (1201) if no motion of the user is detected for a threshold time.

[0318] For example, the first ring electronic device (10) may stop outputting the screen (1201) based on data received from an external electronic device (e.g., the electronic device (101) of FIG. 1 or the external electronic device (50) of FIGS. 5B and 5C) connected to the first ring electronic device (10). The first ring electronic device (10) may control the projection circuit to stop outputting the screen (1201) in response to receiving information from the external electronic device about a state in which the external electronic device is being used by a user. The first ring electronic device (10) may control the projection circuit to stop outputting the screen (1201) in response to receiving from the external electronic device a state in which the external electronic device has been picked up by a user.

[0319] FIG. 13 is a diagram illustrating an operation associated with an external electronic device according to one embodiment.

[0320] FIG. 13 illustrates a state (1310) in which a first ring electronic device (10) (e.g., the electronic device (102) of FIG. 1 or the ring electronic device (200) of FIG. 2) and a second ring electronic device (20) (e.g., the electronic device (102) of FIG. 1 or the ring electronic device (200) of FIG. 2) are worn by a user, and a state (1320) of an external electronic device (50) (e.g., the electronic device (101) of FIG. 1) connected to the first ring electronic device (10) and / or the second ring electronic device (20). The first ring electronic device (10) and the second ring electronic device (20) may each include at least some of the components of the ring electronic device (200) described in FIG. 2. For example, the first ring electronic device (10) and the second ring electronic device (20) may include at least one processor (e.g., processor (210) of FIG. 2), memory (e.g., memory (220) of FIG. 2), communication unit (e.g., communication unit (230) of FIG. 2), camera (e.g., camera (11) of FIG. 4), sensor circuit, and projection circuit.

[0321] In state (1310), the first ring electronic device (10) can output a screen (1301). The second ring electronic device (20) can output a screen (1302). Depending on the embodiment, the screen (1301) can be one of the first projection screen described above or a first partial screen for an integrated projection screen. The screen (1302) can be one of the second projection screen described above or a first partial screen for an integrated projection screen.

[0322] According to one embodiment, while the screen (1301) is being output, the first ring electronic device (10) may receive a status indicating that the external electronic device (50) has been picked up (or information about a status indicating that the external electronic device (50) has been picked up) from an external electronic device (50) connected to the first ring electronic device (10). For example, the external electronic device (50) may sense a status indicating that the user has picked up the external electronic device (50) using a sensor (e.g., an inertial sensor) of the external electronic device (50). The external electronic device (50) may transmit a status indicating that the external electronic device (50) has been picked up to the first ring electronic device (10).

[0323] According to one embodiment, the first ring electronic device (10) may transmit information about the screen (1301) to the external electronic device (50) in response to receiving a status from the external electronic device (50) that the external electronic device (50) has been picked up while the screen (1301) is being output. The first ring electronic device (10) may transmit information about a user interface corresponding to the screen (1301) to the external electronic device (50). According to an embodiment, the first ring electronic device (10) may transmit information about a screen (1302) of the second ring electronic device (20) (or information about a user interface corresponding to the screen (1302)) to the external electronic device (50). According to an embodiment, the second ring electronic device (20) may transmit information about the screen (1302) to the external electronic device (50).

[0324] According to one embodiment, the screen projection of the first ring electronic device (10) and the second ring electronic device (20) may be controlled by an external electronic device (50). According to one embodiment, the screen projection of the second ring electronic device (20) may be controlled by the first ring electronic device (10). In various implementations, some operations may be omitted for simplicity and efficiency. For example, the operation of the first ring electronic device (10) transmitting information on the screen (1301) and / or the operation of the second ring electronic device (20) transmitting information on the screen (1302) may be omitted.

[0325] In state (1320), when a user picks up the external electronic device (50), the external electronic device (50) can output information about a ring electronic device (e.g., a first ring electronic device (10), a second ring electronic device (20)) that is outputting a screen (e.g., a screen (1301), a screen (1302)) through a display (e.g., a display module (160) of FIG. 1). For example, when screens are output by a plurality of ring electronic devices, the external electronic device (50) can provide an interface for selecting a screen (or content) of a ring electronic device to be displayed. For example, the external electronic device (50) can provide an interface for determining whether to display the screen of a ring electronic device that is outputting a screen.

[0326] According to one embodiment, a user may select to display at least a portion of the screens of the first ring electronic device (10) and the second ring electronic device (20) through the display of the external electronic device (50) while the screens (1301) and (1302) are output. The external electronic device (50) may receive information about the screens (1301) and / or (1302) from the first ring electronic device (10) and / or the second ring electronic device (20) based on the user's selection (or selection input).

[0327] According to an example, the external electronic device (50) can output the first screen (1301) and the second screen (1302) through the display. For example, if the first screen (1301) and the second screen (1302) are output as independent first projection screens and second projection screens, respectively, the external electronic device (50) can output the first screen (1301) and the second screen (1302) individually. For example, if the first screen (1301) and the second screen (1302) are output as a first partial screen and a second partial screen for an integrated projection screen, the external electronic device (50) can output the integrated projection screen.

[0350] FIG. 15 is a drawing for explaining an operation of providing a projection screen according to one embodiment.

[0351] FIG. 15 illustrates states (1510, 1520) in which a first ring electronic device (10) (e.g., the electronic device (102) of FIG. 1 or the ring electronic device (200) of FIG. 2), a second ring electronic device (20) (e.g., the electronic device (102) of FIG. 1 or the ring electronic device (200) of FIG. 2), and a third ring electronic device (30) (e.g., the electronic device (102) of FIG. 1 or the ring electronic device (200) of FIG. 2) are worn by a user.

[0352] According to one embodiment, the above-described content regarding the first ring electronic device (10) or the second ring electronic device (20) may be similarly applied to the third ring electronic device (30). In the present disclosure, for convenience of explanation, elements (e.g., projection screen, partial screen, etc.) associated with the first ring electronic device (10) and the second ring electronic device (20) and elements associated with the third ring electronic device (30) are respectively described as 'first -', 'second -', and 'third -'.

[0353] According to one embodiment, the first ring electronic device (10) can continue to detect motion using a camera while being worn on the user's finger (4). The second ring electronic device (20) can continue to detect motion using a camera while being worn on the user's finger (5). The third ring electronic device (30) can continue to detect motion using a camera while being worn on the user's finger (6).

[0355] According to one embodiment, the first ring electronic device (10) can receive information about the output status of the second projection screen (1502) and the third projection screen (1503) from the second ring electronic device (20) and the third ring electronic device (30). The first ring electronic device (10) can determine whether at least a part of the second trigger motion for the integrated projection screen is detected while the first projection screen (1501), the second projection screen (1502), and the third projection screen (1503) are being output.

[0356] According to one embodiment, the first ring electronic device (10) can receive information about the output status of the second projection screen (1502) and the third projection screen (1503) from the second ring electronic device (20) and the third ring electronic device (30), information about the motion detected by the second ring electronic device (20), and information about the motion detected by the third ring electronic device (30). Based on the received information, the first ring electronic device (10) can determine whether at least a part of the second trigger motion for the integrated projection screen is detected while the first projection screen (1501), the second projection screen (1502), and the third projection screen (1503) are output.

[0357] According to one embodiment, the first ring electronic device (10) can detect at least a portion of the second trigger motion.

[0358] According to one embodiment, the first ring electronic device (10) can generate a first partial screen (15100) for the integrated projection screen (15000) based on detecting at least a portion of the second trigger motion, and transmit a request signal for the integrated projection screen to the second ring electronic device (20) and the third ring electronic device (30). The second ring electronic device (20) and the third ring electronic device (30) can generate a second partial screen (15200) and a third partial screen (15300) for the integrated projection screen (15000) based on the request signal for the integrated projection screen.

[0359] In state (1520), the first ring electronic device (10) can output the first partial screen (15100) for the integrated projection screen (15000) as the first projection screen (1501). The second ring electronic device (20) can output the second partial screen (15200) for the integrated projection screen (15000) as the second projection screen (1502). The third ring electronic device (30) can output the third partial screen (15300) for the integrated projection screen (15000) as the third projection screen (1503).

[0360] According to one embodiment, referring to FIG. 15, an integrated projection screen (15000) may include a first partial screen (15100), a second partial screen (15200), and a third partial screen (15300). The integrated projection screen (15000) may include the first partial screen (15100), the second partial screen (15200), and the third partial screen (15300) arranged sequentially. Preferably, the first partial screen (15100), the second partial screen (15200), and the third partial screen (15300) may be arranged without any blank space.

[0361] According to one embodiment, the user interface of the integrated projection screen (15000) and the plurality of partial screens constituting the integrated projection screen (15000) (e.g., the first partial screen (15100), the second partial screen (15200), the third partial screen (15300)), i.e., the content included in the plurality of partial screens, may be similarly applied to the content described above with reference to FIG. 6.

[0362] According to one embodiment, the first partial screen (15100), the second partial screen (15200), and the third partial screen (15300) of the integrated projection screen (15000) may respectively display individual contents of the first ring electronic device (10), the second ring electronic device (20), and the third ring electronic device (30).

[0363] For example, when a second trigger motion for the integrated projection screen is detected while the first projection screen (1501), the second projection screen (1502), and the third projection screen (1503) are output as independent user interfaces, the first ring electronic device (10) may generate and output a first partial screen (15100) for a user interface corresponding to the content of the first ring electronic device (10) based on detecting at least a part of the second trigger motion, and transmit a request signal for the integrated projection screen to the second ring electronic device (20) and the third ring electronic device (30). The second ring electronic device (20) and the third ring electronic device (30) may generate and output the second partial screen (15200) and the third partial screen (15300), respectively, based on the request signal for the integrated projection screen.

[0364] According to one embodiment, different portions of an integrated projection screen (15000) for an extended user interface corresponding to the same content can be output as a first partial screen (15100), a second partial screen (15200), and a third partial screen (15300). That is, the first partial screen (15100), the second partial screen (15200), and the third partial screen (15300) can constitute an integrated interface.

[0365] For example, when a third trigger motion for expanding the user interface for the first partial screen (15100) is detected while the first partial screen (15100), the second partial screen (15200), and the third partial screen (15300) are output as independent user interfaces, the first, second, and third portions of the screen for the expanded user interface corresponding to the content of the first ring electronic device (10) may be output as the first partial screen (15100), the second partial screen (15200), and the third partial screen (15300), respectively.

[0366] For example, if a second trigger motion is detected on the integrated projection screen while any ring electronic device is outputting a projection screen for a user interface corresponding to a home screen (simply, a projection screen representing a home screen), a first portion, a second portion, and a third portion of the screen for an extended user interface corresponding to the contents of another ring electronic device running any application may be output as the first partial screen (15100), the second partial screen (15200), and the third partial screen (15300), respectively. That is, a ring electronic device that is not running any application may be excluded when configuring the integrated projection screen (15000).

[0367] For example, if a second trigger motion is detected for the integrated projection screen while the first projection screen (1501), the second projection screen (1502), and the third projection screen (1503) are output as independent user interfaces, the first, second, and third parts of the screens for the extended user interface corresponding to the content of the main ring electronic device may be output as the first partial screen (15100), the second partial screen (15200), and the third partial screen (15300), respectively. That is, ring electronic devices other than the main ring electronic device (hereinafter, referred to as auxiliary ring electronic devices) may be excluded when configuring the integrated projection screen (15000). According to an embodiment, if the second trigger motion is detected while the auxiliary ring electronic device is executing an application, the execution of the application may be stopped or executed in the background. One of the plurality of ring electronic devices may be set as the main ring electronic device. The main ring electronic device may be selected or changed by the user.

[0368] According to one embodiment, a first part, a second part, and a third part of a screen for an extended user interface corresponding to contents of an external electronic device (e.g., the electronic device (101) of FIG. 1 or the external electronic device (50) of FIG. 5b, FIG. 5c, or FIG. 13) connected to a first ring electronic device (10), a second ring electronic device (20), and a third ring electronic device (30) may be output as a first partial screen (15100), a second partial screen (15200), and a third partial screen (15300), respectively.

[0369] According to one embodiment, the description of the integrated projection screen (e.g., the integrated projection screen (6100) of FIG. 6, the integrated projection screen (7100) of FIG. 7) described above with reference to FIGS. 2 to 14 may be applied to the integrated projection screen (15000), and any redundant descriptions are omitted.

[0370] According to one embodiment, the first ring electronic device (10) may generate and output a first portion for a partial integrated projection screen of the first ring electronic device (10) and the second ring electronic device (20) based on detecting at least a portion of a third trigger motion for expansion of a user interface for the first partial screen (15100) and the second partial screen (15200) while the first partial screen (15100), the second partial screen (15200), and the third partial screen (15300) for the integrated projection screen (15000) are output. For example, the partial integrated projection screen may be output in an area where the first partial screen (15100) and the second partial screen (15200) are output. The second ring electronic device (20) may output the second portion for the partial integrated projection screen. The first ring electronic device (10) can generate and output a first portion for the integrated projection screen (15000) based on detecting at least a portion of a third trigger motion for the partial integrated projection screen and the third partial screen (15300). The second ring electronic device (20) can output a second portion for the integrated projection screen (15000). The third ring electronic device (30) can output a third portion for the integrated projection screen (15000). The descriptions of the various embodiments described above are similarly applied to whether a screen for an extended user interface is generated (or rendered), the rendering subject of the video signal that is the basis of each portion, and any duplicate descriptions are omitted.

[0371] According to one embodiment, the first ring electronic device (10) may split the screen for the extended user interface corresponding to the content of the first ring electronic device (10) to generate the first part, the second part, and the third part based on detecting at least a part of a third trigger motion for extending the user interface for the first partial screen (15100) and the third partial screen (15300) while the first partial screen (15100), the second partial screen (15200), and the third partial screen (15300) for the integrated projection screen (15000) are output. The first ring electronic device (10) may output the first part. The second ring electronic device (20) may output the second part of the screen for the extended user interface. The third ring electronic device (30) may output the third part of the screen for the extended user interface.

[0373] According to one embodiment, the system (16) may include at least one of a first ring electronic device (10) (e.g., the electronic device (102) of FIG. 1 or the ring electronic device (200) of FIG. 2), a second ring electronic device (20) (e.g., the electronic device (102) of FIG. 1 or the ring electronic device (200) of FIG. 2), or an external electronic device (50) (e.g., the electronic device (101) of FIG. 1, or the external electronic device (50) of FIG. 5b, FIG. 5c, or FIG. 13).

[0374] According to one embodiment, the system (16) may further include a third ring electronic device (e.g., the third ring electronic device (30) of FIG. 15). According to an embodiment, the system (16) may include a varying number of ring electronic devices, which is not limited by the present disclosure.

[0377] According to one embodiment, the second ring electronic device (20) (or the third ring electronic device) can perform the operations, functions, and techniques described above with reference to FIGS. 2 to 15. Even if the first ring electronic device (10) is replaced with the second ring electronic device (20) in the description of FIGS. 2 to 15, the same purpose, function, and effect can be achieved. For example, in embodiments of the first ring electronic device (10) and the second ring electronic device (20), if the second ring electronic device (20) performs the operations of the first ring electronic device (10) described above, the second ring electronic device (20) can be replaced with the first ring electronic device (10) (or the third ring electronic device).

The first ring electronic device (10) can comprehensively consider information about motion detected by the first ring electronic device (10) and motion detected by the second ring electronic device (20) to detect various motions (e.g., a second trigger motion for an integrated projection screen).

[0381] For example, the first ring electronic device (10) can receive information about the screen (second projection screen, second partial screen) and content of the second ring electronic device (20) from the second ring electronic device (20).

[0382] For example, the first ring electronic device (10) can receive information about the task of the second ring electronic device (20) from the second ring electronic device (20).

[0383] For example, the first ring electronic device (10) can receive information about the distance between the second ring electronic device (20) and the screen, the projection status of the screen, the screen of the first ring electronic device (10), the alignment status of the screens, the amount of ambient light, etc., detected through the components of the second ring electronic device (200).

[0384] According to one embodiment, the first ring electronic device (10) can generate a request signal for an integrated projection screen of the first ring electronic device (10) and the second ring electronic device (20) and transmit the request signal to the second ring electronic device (20).

[0385] According to one embodiment, the first ring electronic device (10) may generate a first portion and a second portion of a screen for an extended user interface corresponding to the content of the first ring electronic device (10), and transmit the second portion to the second ring electronic device (20).

[0386] According to one embodiment, the system (16) may be implemented to perform the operations, functions, and techniques described above centered around an external electronic device (50) connected to a plurality of ring electronic devices.

[0387] According to one embodiment, the external electronic device (50) can generate a request signal for an integrated projection screen of the first ring electronic device (10) and the second ring electronic device (20) and transmit the request signal to the first ring electronic device (10) and the second ring electronic device (20).

[0388] According to one embodiment, the external electronic device (50) can generate a first portion and a second portion of a screen for an extended user interface corresponding to the content of the external electronic device (50) and transmit the screen to the first ring electronic device (10) and the second ring electronic device (20).

[0389] According to one embodiment, the external electronic device (50) can receive information about motions detected by the first ring electronic device (10) and the second ring electronic device (20), respectively, from the first ring electronic device (10) and the second ring electronic device (20). The external electronic device (50) can detect various motions (e.g., a second trigger motion for an integrated projection screen) by comprehensively considering information about motions detected by the first ring electronic device (10) and motions detected by the second ring electronic device (20).

[0390] According to one embodiment, the external electronic device (50) may transmit a request signal for an integrated projection screen to the first ring electronic device (10) and the second ring electronic device (20) based on detecting at least a portion of the second trigger motion. According to an embodiment, the external electronic device (50) may generate each portion of a screen for an extended user interface corresponding to the content of the external electronic device (50) and transmit it to the first ring electronic device (10) and the second ring electronic device (20). According to an embodiment, the external electronic device (50) may transmit a request signal for an integrated projection screen to the main ring electronic device. For example, when the first ring electronic device (10) is the main ring electronic device, the first ring electronic device (10) may generate and output a first portion of a screen for an extended user interface corresponding to the content of the first ring electronic device (10) based on the request signal for an integrated projection screen, and may generate and transmit a second portion to the second electronic device (20).

[0391] According to one embodiment, the system (16) may be implemented such that a plurality of ring electronic devices cooperate to perform some of the operations, functions, and techniques described above, respectively. For example, a first ring electronic device (10) may receive information about a user's motion detected by the second ring electronic device (20) from a second ring electronic device (20), generate a screen (e.g., a first projection screen) based on the information about the user's motion received from the second ring electronic device (20), and control a projection circuit to output the screen. Additionally, the first ring electronic device (10) may generate a screen for an extended user interface, generate a first portion and a second portion of the screen, and transmit the second portion to the second ring electronic device (20). That is, some of the functions described above may be performed by each ring electronic device, such as the first ring electronic device (10) generating the screen and the second ring electronic device (20) detecting the user's motion.

[0392] According to one embodiment, the system (16) may be implemented such that the external electronic device (50) performs some of the operations, functions, and techniques described above using a plurality of ring electronic devices.
