[0081] According to one embodiment, the at least one camera may include a first camera module (203) configured to photograph the front of the wearable electronic device (200) in a first angular range (a1), a second camera module (205) configured to photograph the front of the wearable electronic device (200) in a second angular range (a2), and a third camera module (207) arranged at the rear of the wearable electronic device (200) and configured to track the direction (DS) of the head of the user (10). For example, the first camera module (203) may be at least partially similar to, or substantially identical to, at least one of the first camera modules (241, 242) illustrated in FIG. 2A. The second camera module (205) may be at least partially similar to, or substantially identical to, at least one of the second camera modules (221, 222, 223, and / or 224) illustrated in FIG. 2A.

[0082] According to one embodiment, the first camera module (203) can capture an image (e.g., a first image) corresponding to the front view of the user (10) by capturing the front of the wearable electronic device (200) at a first angle range (a1). The wearable electronic device (200) can implement a video see-through (VST) device based on the image acquired through the first camera module (203). For example, the wearable electronic device (200) can generate a see-through image based on the image acquired through the first camera module (203).

[0083] According to one embodiment, the second camera module (205) can capture a second angle range (a2) from the front of the wearable electronic device (200) to the ground, thereby obtaining an image (e.g., a second image) corresponding to a lower field of view located below the front field of view of the user (10). Based on the image obtained through the second camera module (205), the wearable electronic device (200) can identify a real object located around the wearable electronic device (200), or a distance between the wearable electronic device (200) and a real object. According to one embodiment, the wearable electronic device (200) can detect a gesture input including a user's hand movement based on the image obtained through the second camera module (205).

The third camera module (207) may obtain information about the gaze of the user (10) by tracking the movement of the user's (10) pupils (11). The wearable electronic device (200) may further utilize sensor input values, such as a geomagnetic sensor or an acceleration sensor, to obtain information about the direction (DS) of the user's (10) head. The wearable electronic device (200) may change the image to be displayed based on the information about the direction (DS) of the user's (10) head. For example, the wearable electronic device (200) may display an immersive space including augmented reality or virtual reality. The wearable electronic device (200) can change the direction in which the immersive space (600) is displayed in conjunction with the movement of the direction (DS) of the head of the user (10). For example, the wearable electronic device (200) can detect the movement of the direction (DS) of the head of the user (10) while displaying the first virtual area (e.g., the first virtual area (610) of FIG. 5) of the immersive space (600). Based on the detection of the movement of the direction (DS) of the head of the user (10), the wearable electronic device (200) can change from a state in which the first virtual area (610) of the immersive space (600) is displayed to a state in which the second virtual area (620) of the immersive space (600) is displayed.

[0085] According to one embodiment, the physical input device (209) may include at least one physical button or at least one physical dial. For example, when the physical input device (209) is implemented in the form of a physical button, the wearable electronic device (200) may perform a designated function in response to a user's (10) input of pressing the physical button. For example, when the physical input device (209) is implemented in the form of a physical dial, the wearable electronic device (200) may perform a designated function in response to a user's (10) input of rotating the physical button in a designated direction. The designated function that the wearable electronic device (200) performs based on the user's (10) input received through the physical input device (209) may include, for example, a function of adjusting the volume or the screen.

[0086] According to one embodiment, the wearable electronic device (200) can change a virtual reality image based on a user's (10) input received through a physical input device (209). For example, the wearable electronic device (200) can change the shape of an immersive space (600) based on a user's (10) input received through the physical input device (209). The wearable electronic device (200) can convert a virtual reality image into a see-through image (or an augmented reality image), or convert a see-through image into a virtual reality image, based on a user's (10) input received through the physical input device (209).

[0088] The operations illustrated in FIG. 4 may be performed by commands stored in a memory (130) (e.g., the memory (130) of FIG. 1). For example, the commands, when executed by a processor (120) (e.g., the processor (120) of FIG. 1), may cause a wearable electronic device (200) (e.g., the electronic device (101) of FIG. 1) to perform the operations illustrated in FIG. 4.

[0089] At least some of the operations illustrated in FIG. 4 may be omitted. At least some of the operations mentioned with reference to other drawings in this disclosure may be additionally inserted before or after at least some of the operations illustrated in FIG. 4.

[0090] According to one embodiment, at least some of the operations illustrated in FIG. 4 may be performed sequentially.

[0091] According to one embodiment, at least some of the operations illustrated in FIG. 4 can be performed in parallel (simultaneously).

[0092] Hereinafter, the operation of a wearable electronic device (200) according to one embodiment will be described with reference to FIGS. 4 to 8.

[0093] In operation 510, a wearable electronic device (200) according to one embodiment may display an immersive space (600) including augmented reality or virtual reality. For example, the wearable electronic device (200) may execute at least one application while displaying the immersive space (600). The wearable electronic device (200) may display an execution screen (e.g., 641, 642, 643, 644 of FIG. 5) of at least one application through a display module (e.g., the first display module (301) and / or the second display module (302) of FIG. 2B). The wearable electronic device (200) can display a virtual area (e.g., the first virtual area (610) of FIG. 5) that is part of an immersive space (600) through a display module (301, 302) in conjunction with the movement of the direction (DS) of the head of the user (10).

[0094] Referring to FIG. 5, reference numeral 600 may represent an immersive space (600) provided by a wearable electronic device (200). The wearable electronic device (200) may detect a direction (DS) of a user's (10) head and display a first virtual area (610) that is part of the immersive space (600) based on the direction (DS) of the user's (10) head. For example, the first virtual area (610) may include a see-through image and an execution screen of at least one application. For example, the wearable electronic device (200) may arrange an execution screen of at least one application within the immersive space (600), and the execution screen of at least one application may or may not be included in the virtual area displayed based on the direction (DS) of the user's (10) head. FIG. 5 illustrates that a wearable electronic device (200) displays a first virtual area (610) that is part of an immersive space (600) based on the direction (DS) of the user's (10) head, and that a first execution screen (641) of a first application and a second execution screen (642) of a second application are included in the first virtual area (610). FIG. 5 illustrates that a third execution screen (643) of a third application and a fourth execution screen (644) of a fourth application are not positioned in the first virtual area (610) corresponding to the direction (DS) of the user's (10) head.

[0095] According to one embodiment, the wearable electronic device (200) can change the virtual area displayed by the display module (301, 302) in response to the movement of the direction (DS) of the head of the user (10). For example, in the immersive space (600), a part of the area corresponding to the first direction (DR1) from the user (10) (or a part of the area corresponding to the first direction (DR1) of the immersive space (600)) can be named a first virtual area (e.g., 610 of FIG. 5). For example, in the immersive space (600), a part of the area corresponding to the second direction (DR2) from the user (10) (or a part of the area corresponding to the second direction (DR2) of the immersive space (600)) can be named a second virtual area (e.g., 620 of FIG. 6). For example, in an immersive space (600), a portion of an area corresponding to a third direction (DR3) from the user (10) (or a portion of an area corresponding to the third direction (DR3) of the immersive space (600)) may be named a third virtual area (e.g., 630 of FIG. 7). According to one embodiment, the wearable electronic device (200) may display a first virtual area (610), a second virtual area (620), or a third virtual area (630) in conjunction with the movement of the direction (DS) of the head of the user (10).

[0096] According to one embodiment, as illustrated in FIG. 5, the wearable electronic device (200) can display a first virtual screen (610) through the display modules (301, 302) when the direction (DS) of the head of the user (10) faces a first direction (DR1). According to one embodiment, as illustrated in FIG. 6, the wearable electronic device (200) can display a second virtual screen (620) through the display modules (301, 302) when the direction (DS) of the head of the user (10) faces a second direction (DR2). According to one embodiment, as illustrated in FIG. 7, the wearable electronic device (200) can display a third virtual screen (630) through the display modules (301, 302) when the direction (DS) of the head of the user (10) faces a third direction (DR3).

[0097] According to one embodiment, the wearable electronic device (200) can control the display modules (301, 302) so that the boundaries between the first virtual screen (610), the second virtual screen (620), or the third virtual screen (630) are not distinguished. In the present disclosure, for convenience of explanation, the immersive space (600) is described by dividing it into the first virtual screen (610), the second virtual screen (620), or the third virtual screen (630), but these can be seamlessly connected to each other and displayed.

[0098] In operation 520, the wearable electronic device (200) according to one embodiment, upon receiving a first trigger, may determine a first direction (DR1) toward which the body of the user (10) is facing using a second camera module (e.g., the second camera module (205) of FIG. 3). For example, the first trigger may be a user (10) input for entering characters into an execution screen (e.g., 641, 642, 643, 644 of FIG. 5) of at least one application included in an immersive space (600).

[0099] According to one embodiment, the first trigger may be a designated gesture input using the user's (10) hand on the execution screen of at least one application (e.g., 641, 642, 643, 644 of FIG. 5). In this case, the wearable electronic device (200) may analyze an image acquired through the second camera module (205) to detect the designated gesture input using the user's (10) hand.

[0100] According to one embodiment, the first trigger may be a user's (10) gaze at a portion of the execution screen of at least one application (e.g., 641, 642, 643, 644 of FIG. 5). In this case, the wearable electronic device (200) may analyze an image acquired through a third camera module (e.g., the third camera module (207) of FIG. 3) to determine whether the user's (10) gaze is at a portion of the execution screen of at least one application (e.g., 641, 642, 643, 644 of FIG. 5).

[0101] According to one embodiment, the wearable electronic device (200) may determine a direction in which the body of the user (10) is facing (e.g., body direction (DB)) in response to receiving a first trigger. For example, the wearable electronic device (200) may determine the positions and directions of both hands, both arms, and both shoulders of the user (10) based on an image acquired through the second camera module (205), and may determine the body direction (DB) of the user (10) based on the determined positions and directions of both hands, both arms, and both shoulders of the user (10).

[0102] In operation 530, the wearable electronic device (200) according to one embodiment may display a character input object (601) in an immersive space (600) based on the determined body direction (DB) of the user (10). For example, if the wearable electronic device (200) determines that the body direction (DB) of the user (10) is the first direction (DR1), the wearable electronic device (200) may display the character input object (601) in the first direction (DR1) of the immersive space (600). Accordingly, the character input object (601) may be displayed in the first direction (DR1) from the body of the user (10) in the immersive space (600).

[0103] The term "character input object (601)" used in various embodiments of the present disclosure may be used interchangeably with terms such as "virtual keyboard."

[0104] According to one embodiment, the character input object (601) may be displayed to the user (10) within the field of view of the first camera module (203) in the direction in which the body is facing. According to another embodiment, the character input object (601) may be displayed in at least a portion where the field of view of the first camera module (203) and the field of view of the second camera module (205) overlap. According to one embodiment, when a physical keyboard (e.g., a keyboard of a laptop) exists in an area corresponding to the direction in which the body is facing, the wearable electronic device (200) may display the character input object (601) in the form of an overlay on the physical keyboard. In this case, the wearable electronic device (200) may set the shape and size of the character input object (601) to be substantially the same as the shape and size of the physical keyboard. According to another embodiment, the wearable electronic device (200) may set the character input object (601) to have at least some of the size, number, or arrangement of keys of a physical keyboard when displaying the character input object (601), and may set the character input object (601) to have at least some of the positions, colors, and designs of keys of the physical keyboard different.

[0105] According to one embodiment, the wearable electronic device (200) may display a character input object (601) in a position suitable for typing by the user (10) by considering the position, shape, and angle of the user's (10) arm or the position, shape, and angle of the hand within the field of view of the first camera module (203) in the direction the body is facing.

[0106] According to one embodiment, the wearable electronic device (200) may display a text input object (601) within the field of view of the first camera module (203) in the direction in which the body is facing, based on an image acquired through the first camera module (203) or the second camera module (205), identify a point where the hand of the user (10) is located, and display the text input object (601) in a portion of an immersive space (600) including the point where the hand is located.

[0107] In operation 540, when the wearable electronic device (200) according to one embodiment detects that the direction (DS) of the head of the user (10) is directed toward the second direction (DR2) while the character input object (601) is displayed in the first direction of the immersive space (600), the wearable electronic device (200) may maintain a state in which the character input object (601) is displayed in the first direction (DR1) of the immersive space (600). For example, when the direction (DB) of the body of the user is fixed in the first direction (DR1), the wearable electronic device (200) may display the character input object (601) in the first direction (DR1) which is the direction of the body (DB), regardless of a change in the direction (DS) of the head of the user (10) moving from the first direction (DR1) to the second direction (DR2).

[0108] Referring to FIG. 6, for example, the wearable electronic device (200) can detect that the direction (DS) of the head of the user (10) moves from the first direction (DR1) to the second direction (DR2) while the direction (DB) of the body of the user (10) is fixed to the first direction (DR1). When the wearable electronic device (200) detects that the direction (DS) of the head of the user (10) moves from the first direction (DR1) to the second direction (DR2), the display module (301, 302) can be controlled to display a second virtual screen (620) of an immersive space (600), but the second virtual screen (620) can not include a character input object (601). The text input object (601) can still be displayed in the first direction (DR1) of the immersive space (600) corresponding to the direction (DB) of the body of the user (10), even though the direction (DS) of the head of the user (10) has moved from the first direction (DR1) to the second direction (DR2).

[0109] Referring to FIG. 7, for example, the wearable electronic device (200) can detect that the direction (DS) of the head of the user (10) moves from the first direction (DR1) to the third direction (DR3) while the direction (DB) of the body of the user (10) is fixed to the first direction (DR1). When the wearable electronic device (200) detects that the direction (DS) of the head of the user (10) moves from the first direction (DR1) to the third direction (DR3), the display module (301, 302) can be controlled to display the third virtual screen (630) of the immersive space (600), but the third virtual screen (630) can not include a character input object (601). The text input object (601) can still be displayed in the first direction (DR1) of the immersive space (600) corresponding to the direction (DB) of the body of the user (10), even though the direction (DS) of the head of the user (10) has moved from the first direction (DR1) to the third direction (DR3).

[0110] Referring to FIG. 8, for example, the wearable electronic device (200) can detect that the body of the user (10) moves in a horizontal direction (e.g., the right direction (801) in FIG. 8) while the direction (DB) of the body of the user (10) is fixed to be facing the first direction (DR1). When the wearable electronic device (200) detects a change in the direction of the body of the user (10) moving in a horizontal direction while the direction (DB) of the body of the user (10) is fixed to the first direction (DR1), the display modules (301, 302) can maintain a state in which the character input object (601) is displayed in the first direction (DR1), which is the direction (DB) of the body of the user (10).

[0111] According to one embodiment, the wearable electronic device (200) may detect an event in which a change in the body direction (DB) of the user (10) is greater than or equal to a specified reference value through the second camera module (205) while displaying a character input object (601) based on the body direction (DB). In response to the detection of the event, the wearable electronic device (200) may re-determine the body direction (DB) by using at least some of the positions of both shoulders, both arms, or both hands of the user (10) through an image input to the second camera module (205).

[0112] According to another example, the wearable electronic device (200) may further utilize sensor input values ​​such as a geomagnetic sensor or an acceleration sensor to detect a change in the body direction (DB) of the user (10). According to one embodiment, the wearable electronic device (200) may distinguish the degree of movement of the user (10) by utilizing sensor input and image input in stages or simultaneously. For example, when the wearable electronic device (200) detects the movement of the wearable electronic device (200) using a geomagnetic sensor or an acceleration sensor, the wearable electronic device (200) may calculate the amount of change in at least a part of the positions of both shoulders, both arms, or both hands of the user (10) through the second camera module (205), thereby detecting whether the body direction (DB) has changed.

[0113] According to another example, the wearable electronic device (200) can detect the movement of the user (10) by analyzing the degree of change in the image acquired through the first camera module (203). When the movement of the user (10) is detected, the wearable electronic device (200) can detect whether the body direction (DB) has changed by calculating the amount of change in at least some of the positions of the user's (10) shoulders, the positions of both arms, or the positions and shapes of both hands through the second camera module (205).

[0114] According to one embodiment, the wearable electronic device (200) can determine, based on at least some of the above-described actions, whether the current user's (10) movement is simply a head turn or a change in the direction of the body (DB), and can vary the position at which the text input object (601) is displayed based on the determined result.

[0115] According to another example, the wearable electronic device (200) can fix the position of the character input object (601) within the immersive space (600) while the user (10) inputs the character input object (601).

[0116] According to another example, the wearable electronic device (200) may display the position of the character input object (601) by fixing it within the virtual space while recognizing that at least a portion of the user's (10) hand is positioned above the character input object (601) being displayed in the image input through the first camera module (203) or the second camera module (205). For example, if even one finger of one of the two hands is positioned within the character input object (601) area, the position of the character input object (601) may not be changed. For example, the character input object (601) area that serves as the reference may be the same size as the displayed character input object (601), or may be set to a slightly larger area that includes the character input object (601) area, and such properties may be selected by the user (10) through a menu such as adjusting the display sensitivity of the character input object (601) in the user (10) settings, etc.

[0117] According to one embodiment, when a hand is detected to be positioned over a text input object (601) through the first camera module (203) or the second camera module (205), an image of a virtual hand corresponding to the position and size of the hand of the user (10) may be displayed on the screen together with the text input object (601). According to one embodiment, the image of the virtual hand may be displayed only within the text input object (601) display area, and the image of the virtual hand may be displayed in an area larger than the text input object (601) area including the text input object (601) display area. According to one embodiment, the image of the virtual hand may include a wrist image. According to one embodiment, the wearable electronic device (200) may generate an image of the virtual hand including an accessory (e.g., a watch or a ring) detected in an image acquired through the first camera module (203) or the second camera module (205). For example, the wearable electronic device (200) may include an image including the user's (10) physical features, such as skin color and tattoos, in the image of the virtual hand from an image acquired through the first camera module (203) or the second camera module (205). According to one embodiment, when the wearable electronic device (200) displays the virtual hand by positioning it over the text input object (601), the wearable electronic device (200) may cause the virtual hand to have a specified transparency. Accordingly, even if the virtual hand is displayed over the text input object (601), the user (10) can check the text input object (601) under the virtual hand.

[0118] Fig. 9 is a flowchart illustrating the operation of a wearable electronic device (200) according to one embodiment. Fig. 10 is an example of a virtual reality image according to changes in the direction of the user's (10) head (DS) and the direction of the user's (10) body (DB) moving from a first direction (DR1) to a second direction (DR2).

[0119] The operations illustrated in FIG. 9 may be performed by commands stored in a memory (130) (e.g., the memory (130) of FIG. 1). For example, the commands, when executed by a processor (120) (e.g., the processor (120) of FIG. 1), may cause a wearable electronic device (200) (e.g., the electronic device (101) of FIG. 1) to perform the operations illustrated in FIG. 9.

[0120] At least some of the operations illustrated in FIG. 9 may be omitted. At least some of the operations mentioned with reference to other drawings in this disclosure may be additionally inserted before or after at least some of the operations illustrated in FIG. 9.

[0121] According to one embodiment, some of the operations illustrated in FIG. 9 may be performed in a changed order.

[0122] According to one embodiment, at least some of the operations illustrated in FIG. 9 can be performed in parallel (simultaneously).

[0123] Hereinafter, the operation of a wearable electronic device (200) according to one embodiment will be described with reference to FIGS. 9 and 10.

[0124] In operation 910, a wearable electronic device (200) according to one embodiment may display a character input object (601) in a first direction (DR1) of an immersive space (600). Operation 910 may be substantially the same as operation 530 described with reference to FIG. 4.

[0125] In operation 920, the wearable electronic device (200) according to one embodiment can detect that the body direction (DB) of the user (10) changes from the first direction (DR1) to the second direction (DR2). For example, the wearable electronic device (200) can track the body direction (DB) of the user (10) using the second camera module (205) while the text input object (601) is displayed to be positioned in the first direction (DR1). The wearable electronic device (200) can determine the positions and directions of both hands, both arms, and both shoulders of the user (10), and based thereon, detect that the body direction (DB) of the user (10) changes from the first direction (DR1) to the second direction (DR2).

[0126] In operation 930, the wearable electronic device (200) according to one embodiment may display a character input object (601) in a second direction (DR2) of the immersive space (600). For example, the wearable electronic device (200) may change the position at which the character input object (601) is displayed from the first direction (DR1) of the immersive space (600) to the second direction (DR2). Accordingly, the character input object (601) may be aligned with the second direction (DR2), which is the changed body direction (DB) of the user (10) within the immersive space (600).

[0127] Referring to FIG. 10, for example, the wearable electronic device (200) can detect that the body direction (DB) of the user (10) has moved from the first direction (DR1) to the second direction (DR2). For example, when the wearable electronic device (200) detects that the body direction (DB) of the user (10) has moved from the first direction (DR1) to the second direction (DR2), the wearable electronic device (200) can set the text input object (601) to move from the first direction (DR1) to the second direction (DR2) in conjunction with the movement of the body direction (DB) of the user (10).

[0128] FIG. 11 is a flowchart illustrating the operation of a wearable electronic device (200) according to one embodiment. FIG. 12 is an example of a scenario in which a desk is located around a user (10) wearing a wearable electronic device (200) according to one embodiment. FIG. 13 is another example of a scenario in which a desk is located around a user (10) wearing a wearable electronic device (200) according to one embodiment. FIG. 14 is an example of a first type of character input object (601) displayed by a wearable electronic device (200) according to one embodiment. FIG. 15 is an example of a second type of character input object (601) displayed by a wearable electronic device (200) according to one embodiment.

[0129] The operations illustrated in FIG. 11 may be performed by commands stored in a memory (130) (e.g., the memory (130) of FIG. 1). For example, the commands, when executed by a processor (120) (e.g., the processor (120) of FIG. 1), may cause a wearable electronic device (200) (e.g., the electronic device (101) of FIG. 1) to perform the operations illustrated in FIG. 11.

[0130] At least some of the operations illustrated in FIG. 11 may be omitted. At least some of the operations mentioned with reference to other drawings in this disclosure may be additionally inserted before or after at least some of the operations illustrated in FIG. 11.

[0131] According to one embodiment, some of the operations illustrated in FIG. 11 may be performed in a changed order.

[0132] According to one embodiment, at least some of the operations illustrated in FIG. 11 may be performed in parallel (simultaneously).

[0133] Hereinafter, the operation of a wearable electronic device (200) according to one embodiment will be described with reference to FIGS. 11 to 15.

[0134] In operation 1110, a wearable electronic device (200) according to one embodiment may display a character input object (601) in a first direction (DR1) of an immersive space (600). Operation 1110 may be substantially the same as operation 530 described with reference to FIG. 4.

[0135] In operation 1120, a wearable electronic device (200) according to one embodiment can detect an external object corresponding to the waist height of a user (10). The wearable electronic device (200) can detect the external object corresponding to the waist height of the user (10) based on an image acquired using at least one of a first camera module (203) or a second camera module (205).

[0136] In operation 1130, the wearable electronic device (200) according to one embodiment may determine whether the external object includes a first plane that satisfies a specified condition. The wearable electronic device (200) according to one embodiment may determine whether the external object includes a plane on which a character input object (601) may be placed. For example, the plane on which the character input object (601) may be placed may be a plane parallel to the ground. The wearable electronic device (200) according to one embodiment may determine whether the external object includes a first plane on which a user's (10) hand may be placed. If the external object includes a first plane on which a user's (10) hand may be placed (e.g., the result of operation 1130 is YES), the wearable electronic device (200) according to one embodiment may perform operation 1140. According to one embodiment, the wearable electronic device (200) may return to operation 1110 or terminate at least a portion of the operation process if the external object does not include a first plane on which the user's (10) hand can be released (e.g., the result of operation 1130 is NO).

[0137] In operation 1140, the wearable electronic device (200) according to one embodiment may display the character input object (601) on a second plane of the immersive space (600) corresponding to the first plane of the external object. For example, the second plane of the immersive space (600) may be a plane that is parallel to the first plane of the external object. When the wearable electronic device (200) moves the position of the character input object (601) to the second plane of the immersive space (600), the wearable electronic device (200) may change the position and / or inclination at which the character input object (601) is displayed.

[0138] Referring to state 1201 of FIG. 12, for example, if an external object (1210) corresponding to the waist height of the user (10) is not detected, the wearable electronic device (200) may set the character input object (601) to be positioned in the first direction (DR1), which is the direction (DB) of the body of the user (10).

[0139] Referring to state 1202 of FIG. 12, for example, if an external object (1210) corresponding to the waist height of the user (10) is detected and the external object includes a first plane on which the user's (10) hand can be placed (e.g., the result of operation 1130 is an example), the wearable electronic device (200) can move the position of the character input object (602) to a second plane of the immersive space (600) corresponding to the first plane (1211) of the external object (1210).

[0140] According to one embodiment, the wearable electronic device (200) may consider the external object (1210) to be an object corresponding to a furniture such as a desk or table if the external object (1210) corresponding to the waist height of the user (10) can place the hand of the user (10) on it, or includes a first plane (1211) parallel to the ground. For example, the wearable electronic device (200) may change the position of the text input object (602) so that the user (10) can control the text input object (602) while placing his / her hand on the first plane (1211) of the external object (1210). For example, the position where the text input object (602) is initially displayed may be any position on an extension line of the recognized direction of the user's body (DB). The location where the text input object (602) is displayed may be moved to a second plane of the immersive space (600) corresponding to the first plane (1211) when an external object (1210) corresponding to the waist height of the user (10) can place the user's (10) hand on it, or when the first plane (1211) is parallel to the ground. When the wearable electronic device (200) moves the location of the text input object (602), it may provide an effect in which the text input object (602) moves to the second plane in a manner similar to metal being attracted to a magnet. Accordingly, the wearable electronic device (200) may provide a user experience in which the user (10) can input text to the text input object (601) while placing his / her hand on the first plane (1211) of the external object (1210) in an environment close to the external object (1210), such as a desk.

[0141] Referring to FIG. 13, for example, the wearable electronic device (200) displays a character input object (601) on a second plane of an immersive space corresponding to a first plane (1211) of an external object (1210), and can adjust an angle (a3) ​​at which the character input object (601) is displayed. For example, the angle (a3) ​​at which the character input object (601) is displayed can be set to a range of about 0 degrees to about 45 degrees, but the present invention is not limited thereto. For example, the wearable electronic device (200) detects the distance between the hand of the user (10) placed on the desk and the upper plane of the desk (e.g., the external object (1210)) (e.g., the first plane (1211) of the external object (1210)), and when the detected distance is greater than a specified distance, the wearable electronic device (200) can increase the angle (a3) ​​at which the character input object (601) is displayed so that the user (10) can easily control the character input object (601).

[0142] According to one embodiment, the wearable electronic device (200) may set the shape of the character input object (601) displayed in operation 1110 differently from the shape of the character input object (602) moved in operation 1140. For example, the character input object (601) displayed in operation 1110 may have a first shape (1410) as illustrated in FIG. 14. For example, the character input object (602) moved and displayed in operation 1140 may have a second shape (1510) different from the first shape (1410) as illustrated in FIG. 15. The shape of the character input object (601) may include at least one of the arrangement, configuration, size, and color of keys, and the wearable electronic device (200) may change at least some of these.

[0143] According to one embodiment, the wearable electronic device (200) may move the display position of the character input object (601) according to the selection of the user (10) while displaying the character input object (601) of the first form (1410) (or the character input object (601) of the second form (1520)). According to one embodiment, the area in which the character input object (601) can move may be limited to a virtual line extending from the body direction (DB) of the user (10) or an area nearby thereof. According to one embodiment, the character input object (601) displayed at the moved position may be the character input object (601) of the first form (1410). According to one embodiment, the wearable electronic device (200) may display the character input object (601) even at an intermediate position between the start point and the end point of the movement while the character input object (601) is moved by the user (10). According to one embodiment, the character input object (601) displayed at the middle position may have at least some of the color, brightness, transparency, size, or color changed.

[0144] According to one embodiment, the wearable electronic device (200) may apply an effect in which, while the text input object (601) is moved by the user (10), the movement speed of the text input object (601) becomes faster as the text input object (601) gets closer to the destination. For example, the user (10) may be provided with a user experience (10) as if the text input object (601) is magnetically attached to the destination.

[0145] According to one embodiment, when the wearable electronic device (200) detects a change in a first plane (e.g., 1211 of FIG. 13) on which a character input object (601) of a second form (602) is displayed, the wearable electronic device (200) can dynamically change the area or slope on which the character input object (601) of the second form (602) is displayed according to the change in the first plane (e.g., 1211 of FIG. 13).

[0146] According to one embodiment, when the area of ​​the first plane (1211) of the recognized external object (1210) is smaller than the area of ​​the character input object (601) to be displayed, the wearable electronic device (200) may reduce the size of the character input object (601) to match the area of ​​the recognized first plane (1211). According to one embodiment, when the area of ​​the recognized first plane (1211) is smaller than the area of ​​the character input object (601) to be displayed, the wearable electronic device (200) may not move the position of the character input object (601). For example, when the area of ​​the recognized first plane (1211) is smaller than the area of ​​the character input object (601) to be displayed, the wearable electronic device (200) may maintain the state 1201 of FIG. 12.

[0147] Fig. 16 is a flowchart illustrating the operation of a wearable electronic device (200) according to one embodiment. Fig. 17 is an example of a notification object (1720) displayed by a wearable electronic device (200) according to one embodiment. Fig. 18 is another example of a notification object (1720) displayed by a wearable electronic device (200) according to one embodiment.

[0148] The operations illustrated in FIG. 16 may be performed by instructions stored in a memory (130) (e.g., the memory (130) of FIG. 1). For example, when the instructions are executed by a processor (120) (e.g., the processor (120) of FIG. 1), the instructions may cause a wearable electronic device (200) (e.g., the electronic device (101) of FIG. 1) to perform the operations illustrated in FIG. 16.

[0149] At least some of the operations illustrated in FIG. 16 may be omitted. At least some of the operations mentioned with reference to other drawings in this disclosure may be additionally inserted before or after at least some of the operations illustrated in FIG. 16.

[0150] According to one embodiment, some of the operations illustrated in FIG. 16 may be performed in a changed order.

[0151] According to one embodiment, at least some of the operations illustrated in FIG. 16 can be performed in parallel (simultaneously).

[0152] Hereinafter, the operation of a wearable electronic device (200) according to one embodiment will be described with reference to FIGS. 16 to 18.

[0153] In operation 1610, a wearable electronic device (200) according to one embodiment may display a character input object (601) in a first direction (DR1) of an immersive space (600). Operation 1610 may be substantially the same as operation 530 described with reference to FIG. 4.

[0154] In operation 1620, a wearable electronic device (200) according to one embodiment can detect that the direction (DS) of the user's head moves from a first direction (DR1) to a second direction (DR2).

[0155] In operation 1630, the wearable electronic device (200) according to one embodiment may display a second virtual area (620) of an immersive space (600) corresponding to the second direction (DR2) based on the direction (DS) of the user's head facing the second direction (DR2). While displaying the second virtual area (620), the wearable electronic device (200) according to one embodiment may maintain a state of displaying a character input object (601) in the first direction (DR1) if the direction (DB) of the user's body is fixed to the first direction (DR1).

[0156] In operation 1630, the wearable electronic device (200) according to one embodiment may display a notification object (e.g., 1720 of FIG. 17) indicating whether the hand of the user (10) and the character input object (601) being displayed in the first direction (DR1) of the immersive space (600) are aligned. For example, while the direction (DS) of the head of the user (10) is facing the second direction (DR2), the wearable electronic device (200) may display a second virtual area (620) of the immersive space (600). While displaying the second virtual area (620), the wearable electronic device (200) may display the notification object (1720) on a part of the second virtual area (620) so that the user (10) can control the character input object (601) that is not being displayed due to its position in the first direction (DR1), which is the direction (DB) of the user's body. A user (10) can receive a user experience of using an input function by extending a hand toward a character input object (601) located in a first direction (DR1) and simultaneously viewing a second virtual area (620) located in a second direction (DR2) through a wearable electronic device (200).

[0157] Referring to FIG. 17, for example, the wearable electronic device (200) can detect that the direction (DS) of the head of the user (10) is directed toward the second direction (DR2) while the direction (DB) of the body of the user (10) is fixed to be directed toward the first direction (DR1). When the wearable electronic device (200) detects that the direction (DS) of the head of the user (10) is directed toward the second direction (DR2) while the direction (DB) of the body of the user (10) is fixed to be directed toward the first direction (DR1), the wearable electronic device (200) can display a notification object (1720) together with a second virtual screen (620). In order to display the notification object (1720), the wearable electronic device (200) can track the position of the hand of the user (10) and determine whether the tracked position of the hand of the user (10) is aligned with the text input object (601) being displayed in the first direction (DR1).

[0158] According to one embodiment, the notification object (1720) may include a hand object (1721) indicating the alignment state of the user's (10) hand, or a keyboard object (1722) indicating a character input object (601), but the present invention is not limited thereto.

[0159] According to one embodiment, the location of the notification object (1720) can be set independently from the location of the execution screen of at least one application displayed in the second virtual area (620), for example, the third execution screen (643) of the third application.

[0160] According to one embodiment, the wearable electronic device (200) can intuitively notify whether the hand of the user (10) and the character input object (601) are aligned through the relative positions of the hand object (1721) and the keyboard object (1722) included in the notification object (1720). For example, when the hand of the user (10) and the character input object (601) are aligned, the wearable electronic device (200) can display the hand object (1721) and the keyboard object (1722) to be aligned with each other, as illustrated in FIG. 17. For example, when the hand of the user (10) and the character input object (601) are not aligned, the wearable electronic device (200) may display a hand object (1721) and a keyboard object (1722) so as to be not aligned with each other, as illustrated in FIG. 18, and may display a direction guidance object (1723) to guide the user (10) to move the position of the hand toward the character input object (601). The direction guidance object (1723) may be in the form of an arrow, for example, but the present invention is not limited thereto.
