Description

Wearable device that automatically turns off at least one microphone based on a change in input method and a control method thereof

[0001] This document relates to a wearable device that automatically turns off at least one microphone based on a change in input method and a control method thereof.

[0002] The variety of services and additional features offered through wearable devices, such as smart glasses, is steadily increasing. To enhance the utility of these devices and satisfy the diverse needs of users, telecommunications service providers and wearable device manufacturers are competitively developing wearable devices that offer a variety of features and differentiate themselves from competitors. Consequently, the various functions offered through wearable devices are also becoming increasingly sophisticated.

[0003] Conventional wearable devices have provided a function or operation that switches the microphone to an OFF state after a specified period of time has elapsed from the time at which at least one microphone is set to an ON state. However, conventional wearable devices have not provided a function or operation that switches the microphone to an OFF state based on user input other than user speech (e.g., a user gesture).

[0004] Furthermore, wearable devices according to conventional technology have provided users with functions or actions that indicate the user's gaze point through an indicator. However, wearable devices according to conventional technology have failed to provide functions or actions that can intuitively inform the user whether a virtual object located in the area focused by the user's gaze is controllable via voice commands.

[0005] According to one embodiment of the present document, when a focused virtual object is controllable by voice command based on a user's input (e.g., the user's gaze), a wearable device may be provided that can intuitively inform the user that the virtual object can be controlled by the user's speech by providing a visual effect around the virtual object.

[0006] According to one embodiment of the present document, a wearable device can be provided that provides visual effects that do not interfere with a user's content browsing, by providing visual effects optimized for a focused virtual object based on the shape of the virtual object and / or the distance from the user.

[0007] According to one embodiment of the present document, a control method of a wearable device can be provided that, when a virtual object focused on a user's input (e.g., the user's gaze) can be controlled by a voice command, provides a visual effect around the virtual object to intuitively inform the user that the virtual object can be controlled by the user's speech.

[0008] According to one embodiment of the present document, a method for controlling a wearable device that provides a visual effect that does not interfere with a user's content browsing can be provided, since a visual effect optimized for a focused virtual object can be provided to the user by providing a visual effect based on the shape of the virtual object and / or the distance from the user.

These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

For example, when heat is generated in the circuit board (241) or the battery (243), the connecting member (235) can block the heat from being transferred to the portion that comes into contact with the user's body, and can disperse or release the heat through the portion that does not come into contact with the user's body. According to one embodiment, a portion of the connecting member (235) that is configured to come into contact with the user's body may be interpreted as a part of the inner case (231), and a portion of the connecting member (235) that is not configured to come into contact with the user's body may be interpreted as a part of the outer case (233). According to one embodiment (not shown), the first case (231a) and the second case (231b) may be configured as an integral body without the connecting member (235), and the third case (233a) and the fourth case (233b) may be configured as an integral body without the connecting member (235). According to various embodiments, in addition to the illustrated components, other components (e.g., the antenna module (197) of FIG. 1) may be further included, and information about objects or environments may be provided from an external electronic device (e.g., the electronic device (102, 104) or server (108) of FIG. 1) through a network (e.g., the first network (198) or the second network (199) of FIG. 1) using the communication module (190).

[0123] In FIGS. 2A to 2C, only the wearable device (200) is illustrated and described, but it is not limited thereto, and some components of the wearable device (200) illustrated in FIGS. 2A to 2C may also be included in electronic devices such as smartphones and tablet PCs.

[0124] The wearable device (200) according to various embodiments of the present document can identify whether the user (210) is wearing the wearable device (100) through a proximity sensor included in the wearable device (200). Alternatively, the wearable device (200) according to various embodiments of the present document can determine whether the wearable device (200) is being worn by the user (610) based on whether the frame of the wearable device (200) is unfolded (e.g., unfolded state) and whether proximity of the user (610) is detected while the frame of the wearable device (200) is unfolded, through an angle sensor provided in a hinge portion of the wearable device (200).

[0125] FIG. 3 illustrates an eye tracking camera structure of a wearable device according to various embodiments. Referring to FIG. 3, a wearable device (300) (e.g., a glasses-type device) may include an ET (eye tracking) camera (310), a display (321), an input optical member (322), a first waveguide (323), an output optical member (324), a first splitter (341), a second waveguide (342), and a second splitter (343).

[0126] According to various embodiments, the user's pupil (330) may be captured by the ET camera (310) through a first splitter (341) (e.g., a splitter for gaze tracking), a second waveguide (342), and a second splitter (343). The ET camera (310) may detect the pupil (330) in the captured image and track the user's gaze by confirming the movement of the detected pupil (330).

[0127] According to various embodiments, an image output through the display (321) may be reflected through the input optical member (322) and the first waveguide (323) and displayed through the output optical member (324). The wearable device (300) may output an image through the display (321) and at the same time track the user's gaze by checking the movement of the user's pupils (330).

[0128] FIG. 4 is an exemplary drawing for explaining a function or operation of changing and displaying a display property of a virtual object (e.g., a first virtual object (510 of FIG. 5a)) based on the shape (e.g., whether it is a two-dimensional shape or a three-dimensional shape) and the viewing distance of the virtual object (e.g., a first virtual object (510)) by a wearable device (200) according to one embodiment of the present document.

[0129] Referring to FIG. 4, a wearable device (200) according to an embodiment of the present document may obtain user gaze information in operation 410. For example, the wearable device (200) according to an embodiment of the present document may identify a user's gaze direction using at least one camera (e.g., a camera module (250) of FIG. 2B). The wearable device (200) according to an embodiment of the present document may identify a user's gaze direction using a camera module capable of tracking the user's gaze. The wearable device (200) according to an embodiment of the present document may obtain gaze information (e.g., track a gaze direction) using a pupil-corneal reflection method. The pupil-corneal reflection method according to an embodiment of the present document may include a method of detecting a gaze direction based on a pupil pattern and a glint pattern, which is a reflected light of the cornea. A wearable device (200) according to one embodiment of this document may also obtain information on a user's gaze (e.g., track the direction of gaze) through image analysis of the pattern of the boundary line of the pupil or iris of the eye.

[0130] According to one embodiment of the present document, the wearable device (200) may determine, in operation 420, whether a virtual object located in the direction of the user's gaze is an object controllable by voice commands. According to one embodiment of the present document, the wearable device (200) may determine whether a virtual object can be controlled by voice commands based on metadata stored in association with the virtual object and / or an application corresponding to the virtual object. The metadata according to one embodiment of the present document may include an identifier (e.g., a flag value) indicating whether the virtual object can be controlled by voice commands. According to one embodiment of the present document, the wearable device (200) may determine, based on the value (e.g., 0 or 1) of the identifier included in the metadata, whether a virtual object located in the direction of the user's gaze is an object controllable by voice commands. Alternatively, the wearable device (200) according to one embodiment of the present document may transmit information about a virtual object currently located in the direction of the user's gaze to an external electronic device (e.g., a server) and obtain a response from the external electronic device that includes information about whether the virtual object currently located in the direction of the user's gaze can be controlled by voice. The wearable device (200) according to one embodiment of the present document may determine whether the virtual object currently located in the direction of the user's gaze can be controlled by voice based on the response obtained from the external electronic device. Alternatively, the wearable device (200) according to one embodiment of the present document may determine whether the virtual object currently located in the direction of the user's gaze can be controlled by voice using a look-up table in which a correspondence relationship between an application corresponding to a virtual object and an identifier indicating whether voice command control is possible is defined, the look-up table being stored in advance in the wearable device (200).

[0131] According to one embodiment of the present document, the wearable device (200) can determine the type of the real object when the user's gaze is directed toward a real object rather than a virtual object, and determine whether the real object can be controlled by a voice command based on the determined type. For example, according to one embodiment of the present document, if the real object is an electronic device, the wearable device (200) can determine whether pairing with the electronic device is possible. For example, according to one embodiment of the present document, the wearable device (200) can determine that pairing is possible if the real object located in the direction of the user's gaze is a device registered under the same account as the wearable device (200). According to one embodiment of the present document, if it is determined that pairing with an electronic device is possible, the wearable device (200) can identify the electronic device capable of pairing as an electronic device controllable by a voice command. For example, when a wearable device (200) according to one embodiment of the present document is paired with an electronic device (e.g., a laptop), if a voice command “turn off the laptop” is obtained, the wearable device (200) may request the electronic device (e.g., the laptop) to turn off the power of the electronic device (e.g., the laptop). According to one embodiment of the present document, in response to such a request, the electronic device (e.g., the laptop) may be controlled to turn off the power of the electronic device. When pairing is determined to be possible, the wearable device (200) according to one embodiment of the present document may provide a designated visual effect (e.g., a border with a designated color) around a real object. Alternatively, according to one embodiment of the present document, even if the wearable device (200) and the electronic device (e.g., the laptop) are paired, if voice control authority is blocked through at least one device, control through a voice command may not be possible for at least one device.In such a case, the wearable device (200) according to one embodiment of the present document may not provide a visual effect (e.g., a border with a specified color) around the electronic device.

[0132] According to one embodiment of the present document, a wearable device (200) can determine whether visual processing is possible to transform the shape of a real object or to hide it from the user's view when the real object is not an electronic device, such as a chair. According to one embodiment of the present document, a wearable device (200) can determine, for example, using a learned artificial intelligence model, whether visual processing is possible to transform the shape of a real object or to hide it from the user's view. According to one embodiment of the present document, when a real object, not an electronic device, is determined to be controllable, the wearable device (200) can provide a designated visual effect around the real object.

[0133] According to one embodiment of the present document, the wearable device (200) may determine, in operation 430, the shape of a virtual object and / or whether the virtual object is located within a visible range. According to one embodiment of the present document, operation 430 may be performed regardless of whether at least one object is an object controllable by voice command. For example, according to one embodiment of the present document, the wearable device (200) may identify and store information on the shape and / or distance of at least one object included within the field of view of the wearable device (200), and, if at least one object is identified as an object controllable by voice, may change and display the display properties of the at least one object. However, operation 430 may also be performed after at least one object is identified as an object controllable by voice. According to one embodiment of the present document, the wearable device (200) may determine whether the virtual object is a two-dimensional shape or a three-dimensional shape. The wearable device (200) according to one embodiment of the present document can determine whether a virtual object (e.g., the first virtual object (510)) is located within a visible range based on the area that the virtual object occupies within the field of view of the wearable device (200). For example, the wearable device (200) according to one embodiment of the present document can determine that the virtual object is located outside the visible range if the virtual object occupies less than 10% of the field of view area. However, the wearable device (200) according to one embodiment of the present document may perform operation 430 without including the function or operation of determining whether the virtual object is located within the visible range in operation 430. In this case, in operation 440, the wearable device (400) according to one embodiment of the present document can change and display display properties according to the properties of an object determined to have been gazed at by the user, regardless of whether the virtual object is located within the visible range.

[0134] According to one embodiment of the present document, the wearable device (200) may, in operation 440, change and display the display properties of the virtual object based on the determination result regarding the shape and / or visibility distance of the virtual object. For example, according to one embodiment of the present document, if the shape of the virtual object is a two-dimensional shape and the virtual object is located outside the visibility range, the wearable device (200) may enlarge the size of the virtual object according to a specified ratio and then provide a visual effect.

[0135] FIG. 5A is an exemplary drawing for explaining a function or operation of changing and displaying the display properties of an input field (512) when a virtual object (e.g., a first virtual object (510)) according to one embodiment of the present document includes an input field (512). FIG. 5B is an exemplary drawing for explaining an input field (512) whose display properties have been changed according to one embodiment of the present document. FIG. 5D is an exemplary drawing for explaining a function or operation of changing and displaying the display properties of an input field (512) when a virtual object (e.g., a first virtual object (510)) according to one embodiment of the present document includes an input field (512).

[0136] Referring to FIG. 5A, a wearable device (200) according to an embodiment of the present document can determine whether a virtual object includes an input field (512). When a user's input (e.g., the user's gaze) is directed toward the input field (512), the wearable device (200) according to an embodiment of the present document can change the display properties of the input field (512). As an example of changing the display properties of the input field (512), the wearable device (200) according to an embodiment of the present document can express the color of the input field (512) as a first designated color (e.g., change from white to blue) and provide a speech hint inside the input field (512). However, the wearable device (200) according to an embodiment of the present document may not provide the speech hint and may only display the color of the input field (512) as the first designated color. According to one embodiment of the present document, a speech hint may include a pre-specified speech command (e.g., "Show me the latest photos!") for an application corresponding to a virtual object (e.g., a gallery application). Alternatively, according to one embodiment of the present document, a speech hint may include a speech command most recently input by a user through an application corresponding to a virtual object (e.g., an intelligent assistant application). Alternatively, according to one embodiment of the present document, a speech hint may include at least one recommended speech command determined according to a specified priority. According to one embodiment of the present document, a wearable device (200) may control a speech hint (550) to be displayed while continuously moving in a specified direction. According to one embodiment of the present document, a wearable device (200) may display an indicator related to a user speech (e.g., an indicator (540) of FIG. 5B) within an input field (512) whose display properties have been changed, or outside an input field (512) whose display properties have been changed.A wearable device (200) according to one embodiment of the present document may display an indicator related to the processing of a user's speech (e.g., an indicator (540) of FIG. 5b) in association with the user's speech input status, together with an input field (512) whose display properties have been changed. This is described in detail in FIG. 5b below.

[0137] FIG. 5b is an exemplary drawing for explaining an indicator related to user speech processing displayed by a wearable device (200) according to one embodiment of the present document.

[0138] Referring to FIG. 5B, a wearable device (200) according to one embodiment of the present document may display an indicator (540) related to a user's speech input, as illustrated in FIG. 5B. The indicator (540) according to one embodiment of the present document may have different sizes and / or shapes depending on the user's speech processing status. In FIG. 5B, "listening (540a)" may refer to a state before acquiring the user's speech. In the "listening (540a)" state according to one embodiment of the present document, the microphone of the wearable device (200) may be set to an on state, or the microphone of the wearable device (200) may be switched from an off state to an on state according to a user's input. In FIG. 5B, "streaming (540b)" may refer to a state in which the user's speech is being acquired. In the "streaming (540b)" state according to one embodiment of the present document, the size and / or shape of the indicator (540) may be displayed while repeatedly changing. In the "streaming (540b)" state according to one embodiment of the present document, it may be determined whether a wake word (e.g., "Hi Bixby!") and / or a spoken command (e.g., "Tell me today's weather!") is obtained from the user by the wearable device (200). In FIG. 5b, 120% and 150% are shown as examples of the size of the indicator (540), but these are examples for explaining the indicator according to one embodiment of the present document. In the "streaming (540b)" state according to one embodiment of the present document, the microphone of the wearable device (200) may be set to an on state. In FIG. 5c, “processing (540c)” may mean a state in which the wearable device (200) according to one embodiment of the present document acquires the user’s speech and processes the user’s speech.According to one embodiment of the present document, the wearable device (200) can process the user's acquired speech using an artificial intelligence module (e.g., LLM) included in the wearable device (200). Alternatively, according to one embodiment of the present document, the wearable device (200) can transmit information about the user's acquired speech to an external device (e.g., LLM server) that is operatively connected to the wearable device (200) to process the user's speech, and can obtain information about the result from the external device. In the "streaming (540b)" state according to one embodiment of the present document, the microphone of the wearable device (200) can be maintained in an on state or switched to an off state. In FIG. 5c, "standby (540d)" can mean a state after processing the user's speech. A wearable device (200) according to one embodiment of the present document may provide a result generated by an artificial intelligence module of the wearable device (200) and / or a result acquired from an external server as a response to a user's speech input. In a "standby (540d)" state according to one embodiment of the present document, the microphone of the wearable device (200) may be maintained in an on state or switched to an off state. An indicator (540) according to one embodiment of the present document may be displayed around a virtual object.

[0139] FIG. 5C is an exemplary diagram illustrating a function or operation of a wearable device (200) according to one embodiment of the present document to display a speech hint (550) displayed within an input field (512) whose display properties have been changed. Referring to FIG. 5C, the wearable device (200) according to one embodiment of the present document may provide a speech hint (550) while providing a visual effect (e.g., VI effect) (552) (e.g., a border with a specified color) around the input field (512). The speech hint according to one embodiment of the present document may be provided when it is identified that a virtual object designated by a user is gazed at for a specified period of time (e.g., 5 seconds) or longer in order to provide a recommended speech command to the user. Alternatively, the speech hint according to one embodiment of the present document may be provided when a user's action is identified but the identified action is not a gesture of a pre-specified type. Alternatively, the speech hint according to one embodiment of the present document may be provided from the time when the virtual object is first displayed, regardless of the specified time and / or input gesture. The speech hint according to one embodiment of the present document may include a pre-specified speech command (e.g., "Show me the latest photos!") for an application corresponding to the virtual object (e.g., a gallery application). Alternatively, the speech hint according to one embodiment of the present document may include a speech command most recently input by the user through an application corresponding to the virtual object (e.g., an intelligent assistant application). Alternatively, the speech hint according to one embodiment of the present document may include at least one recommended speech command determined according to a specified priority. The wearable device (200) according to one embodiment of the present document may control the speech hint (550) to be displayed while continuously moving in a specified direction. The wearable device (200) according to one embodiment of the present document may also provide only the speech hint (550) without providing a visual effect (552).

[0140] FIG. 5D is an exemplary drawing for explaining a function or operation of determining whether a virtual object (e.g., a second virtual object (510a), a third virtual object (510b), and / or a fourth virtual object (510c)) is within a visible range based on the distance between the virtual object (e.g., a second virtual object (510a), a third virtual object (510b), and / or a fourth virtual object (510c)) and the user, by a wearable device (200) according to one embodiment of the present document. Referring to FIG. 5D, the wearable device (200) according to one embodiment of the present document can determine whether the virtual object is located within a visible range based on a ratio of occupying a field of view of the wearable device (200). The second virtual object (510a) (e.g., an execution screen of a gallery application) according to one embodiment of the present document may include a virtual object identified as having the largest ratio of occupying a field of view of the wearable device (200) among a plurality of virtual objects. A third virtual object (510b) according to one embodiment of the present document (e.g., an execution screen of a call application) may include a virtual object identified as having a proportion of the field of view of the wearable device (200) that substantially occupies an average area among a plurality of virtual objects. A fourth virtual object (510c) according to one embodiment of the present document (e.g., an execution screen of an intelligent assistance application) may include a virtual object identified as having a proportion of the field of view of the wearable device (200) that is the smallest among a plurality of virtual objects.

[0141] A wearable device (200) according to one embodiment of the present document may provide a first speech hint (514) and a second speech hint (514) to virtual objects (e.g., a second virtual object (510a) and a third virtual object (510b)) located within a visible range, respectively.

[0147] Referring to FIGS. 6A and 6B , the wearable device (200) according to one embodiment of the present document may determine, in operation 605, whether a virtual object exists in a direction gazed by the user. The wearable device (200) according to one embodiment of the present document may determine, in operation 610, whether a virtual object exists within a visible distance. The wearable device (200) according to one embodiment of the present document may determine, in operation 615, whether a virtual object has a two-dimensional shape. The wearable device (200) according to one embodiment of the present document may determine, in operation 630, whether a shape of the virtual object has a three-dimensional shape. The wearable device (200) according to one embodiment of the present document may change a display property in a three-dimensional object expression manner and display it, in operation 650, if the virtual object is determined to have a three-dimensional shape in operation 630. FIG. 9A is an exemplary diagram for explaining a visual effect (e.g., a sixth visual effect (910a)) displayed when a virtual object (e.g., a seventh virtual object (910)) according to one embodiment of the present document has a three-dimensional shape. FIG. 9B is an exemplary diagram for explaining a function or operation of a wearable device (200) according to one embodiment of the present document to display a visual effect on a virtual object having a three-dimensional shape based on a virtual plane. Referring to FIG. 9A, the wearable device (200) according to one embodiment of the present document can provide a visual effect (e.g., a sixth visual effect (910a)) having a specified color of a rectangular parallelepiped shape including a three-dimensional virtual object, based on the fact that a three-dimensional virtual object can be controlled according to a voice command.Referring to FIG. 9b, a wearable device (200) according to one embodiment of the present document may set a virtual plane (920a) overlapping with a three-dimensional virtual object, and provide a visual effect (e.g., a seventh visual effect (910b)) having a specified color for a line (920b) (e.g., a line in the Y-axis direction) or surface (e.g., an XY plane as shown in the lower drawing of FIG. 9b) overlapping the virtual plane (920a) and the three-dimensional object.

[0148] According to one embodiment of the present document, the wearable device (200) may determine, at operation 620, whether the focused virtual object includes a single object with which interaction is possible (e.g., whether the object with which interaction is possible is a single object). According to one embodiment of the present document, if the focused virtual object is a multi-interaction object (e.g., if there are multiple objects with which interaction with the user is possible within a specified area), the wearable device (200) may change the display properties so that the multiple objects are grouped, at operation 645. FIG. 8A is an exemplary drawing for explaining a function or operation of the wearable device (200) according to one embodiment of the present document to provide a visual effect of grouping multiple virtual objects.

[0159] FIG. 16 is an exemplary drawing for explaining a function or operation of a wearable device (200) according to one embodiment of the present document to control at least one microphone (e.g., a microphone module) according to a user input (e.g., a user gesture).

[0160] Referring to FIG. 16, a wearable device (200) according to an embodiment of the present document may, in operation 1610, switch at least one microphone (e.g., a microphone module (247)) from an off state to an on state based on an interaction between at least one virtual object (510) and a user (1750) wearing the wearable device (200). At least one microphone (e.g., a microphone module (247)) according to an embodiment of the present document may be set to an off state when the wearable device (200) is worn by the user (e.g., before the virtual object (510) is displayed). At least one microphone (e.g., a microphone module (247)) according to an embodiment of the present document may be switched from an off state to an on state when the virtual object (510) is displayed or a user input (e.g., a user's gaze) for the virtual object (510) is obtained. However, this is exemplary, and at least one microphone (e.g., microphone module (247)) according to one embodiment of the present document may be set to an on state even when worn by a user (e.g., before the virtual object (510) is displayed). In this case, the wearable device (200) according to one embodiment of the present document may maintain the state of the at least one microphone in an on state based on interaction with the user. The wearable device (200) according to one embodiment of the present document may further perform an operation of determining whether the virtual object (510) is an object that can be controlled through the user's speech, in operation 1610. The wearable device (200) according to one embodiment of the present document may determine whether the virtual object (510) is an object that can be controlled through the user's speech, for example, based on metadata (e.g., a flag value) stored in association with the virtual object (510) that is displayed or to be displayed.A wearable device (200) according to one embodiment of this document can switch the microphone module (247) from an off state to an on state or maintain the on state when the virtual object (510) is an object controllable through the user's speech.

[0161] FIGS. 17A and 17B are exemplary drawings for explaining a function or operation of switching a microphone module from an off state to an on state according to a user input (e.g., a user's gaze toward a virtual object) for a virtual object according to one embodiment of the present document. Referring to FIGS. 5A and 5B , a wearable device (200) according to one embodiment of the present document may display a virtual object (510) as illustrated in FIG. 5A . The wearable device (200) according to one embodiment of the present document may display an area (e.g., a border (1712) area) of the virtual object (510) in a first designated color (e.g., gray) before a user input (e.g., a user's gaze) for the virtual object (510) is obtained (e.g., when the microphone module (247) is in an off state). According to one embodiment of the present document, the wearable device (200) may switch the microphone module (247) from an off state to an on state when an interaction with the user (e.g., the user's gaze toward the virtual object (510)) occurs (e.g., when a user input is obtained), as illustrated in FIG. 17b. According to one embodiment of the present document, the wearable device (200) may display an area (e.g., a border (1712) area) of the virtual object (510) in a second designated color (e.g., purple) as illustrated in FIG. 5b to inform the user that the microphone module (247) has been switched on (e.g., to inform the user that the virtual object (247) can be controlled via a voice command).

[0162] FIG. 5c is an exemplary drawing for explaining a function or operation of a wearable device (200) providing a speech hint according to one embodiment of the present document.

[0163] Referring to FIG. 5c, a wearable device (200) according to one embodiment of the present document may provide a speech hint (1730) as a virtual object when a specified time (e.g., 5 seconds) has elapsed while the microphone module (247) is set to ON. The speech hint (1730) according to one embodiment of the present document may include a command for controlling the virtual object (510) by voice.

[0164] Returning to FIG. 4 again, the wearable device (200) according to one embodiment of the present document can determine, in operation 1620, whether a user input (e.g., a user gesture) other than a user speech is detected using at least one camera (e.g., a camera module (250)) while at least one microphone (e.g., a microphone module (247)) is turned on. FIG. 5d is an exemplary drawing for explaining a function or operation of determining the intention of another user input (e.g., a user gesture input) based on an image acquired through a camera module (e.g., a third camera module (256)) while the wearable device (200) according to one embodiment of the present document is worn by a user. Referring to FIG. 5d, the wearable device (200) according to one embodiment of the present document can determine whether a body part (e.g., a user's hand) of a user is detected using a camera module (e.g., a third camera module (256)). According to one embodiment of the present document, the wearable device (200) may determine that the user has an intention to input a specified gesture when a part of the user's body (e.g., the user's hand) is detected. According to one embodiment of the present document, the wearable device (200) may determine that the user is attempting to input a gesture (e.g., determine that the user has an intention to input a gesture) by determining a matching rate between the movement of the user's hand and a pre-specified gesture as illustrated in FIG. 5E, and when the determined matching rate is greater than or equal to a threshold rate (e.g., 50%). According to one embodiment of the present document, the wearable device (200) may determine that the user has an intention to input a user input when the camera module (247) detects that the user is holding an external device in his / her hand, or when the user is pointing at a specified virtual object through the controller.In this case, the wearable device (200) according to one embodiment of the present document can process the user's utterance through a limited utterance processing method (e.g., processing in the wearable device (200) and / or a large language model (LLM) server based on pre-designated utterances (e.g., "select" and similar utterances (e.g., "select", "click", "push", etc.)) when the user's utterance is input. For example, when a command such as "copy URL" is obtained from the user, "copy URL" can be a clear utterance command included in the pre-designated utterances. Therefore, the wearable device (200) according to one embodiment of the present document can process the utterance command obtained from the user based on the limited utterance processing method. However, if, for example, a slang word that is not included in the pre-designated utterance is input as a utterance command, the wearable device (200) according to one embodiment of the present document may not process the input utterance command or may provide the user with a guide message including a request to input the correct utterance. Information about utterances similar to the pre-designated utterances according to one embodiment of the present document may be acquired through results learned through pre-designation or learning of the wearable device (200). According to one embodiment of the present document, the gestures illustrated in FIG. 5E are exemplary, and the types of pre-designated gestures may be further added.

[0165] According to an embodiment of the present document, the wearable device (200) may determine, in operation 1630, whether the gesture corresponds to a predefined gesture for controlling a virtual object based on the determination of whether a gesture is detected. According to an embodiment of the present document, the wearable device (200) may determine, when a movement of the user's hand acquired through a camera module (e.g., the third camera module (256)) is detected, whether the movement of the user's hand corresponds to a predefined gesture. FIG. 5F is an example diagram for explaining predefined gestures for controlling a virtual object (510) according to an embodiment of the present document. Referring to FIG. 5E, the wearable device (200) according to an embodiment of the present document may determine whether the user's hand movement (e.g., gesture) is a swipe right gesture for moving the position of the virtual object (510) to the right. According to one embodiment of the present document, a wearable device (200) can determine whether a user's hand motion (e.g., gesture) is a swipe left gesture for moving a position of a virtual object (510) to the left. According to one embodiment of the present document, a wearable device (200) can determine whether a user's hand motion (e.g., gesture) is a swipe down gesture for moving a position of a virtual object (510) downward. According to one embodiment of the present document, a wearable device (200) can determine whether a user's hand motion (e.g., gesture) is a swipe up gesture for moving a position of a virtual object (510) upward. According to one embodiment of the present document, a wearable device (200) can determine whether a user's hand motion (e.g., gesture) is a rotate right gesture for rotating a virtual object (510) to the right. A wearable device (200) according to one embodiment of the present document can determine whether a user's hand motion (e.g., gesture) is a rotate left gesture for rotating a virtual object (510) in the left direction.A wearable device (200) according to one embodiment of the present document can determine whether a user's hand motion (e.g., gesture) is a zoom-in gesture for enlarging the size of a virtual object (510). A wearable device (200) according to one embodiment of the present document can determine whether a user's hand motion (e.g., gesture) is a zoom-out gesture for reducing the size of a virtual object (510). However, the user gestures illustrated in FIG. 5e are exemplary, and various other gestures may be stored in the wearable device (200) as pre-designated gestures.

[0166] According to one embodiment of the present document, the wearable device (200) may, in operation 1640, keep at least one microphone (e.g., microphone module (247)) on or turn it off based on a determination as to whether a gesture corresponds to a pre-designated gesture. According to one embodiment of the present document, the wearable device (200) may determine whether a user gesture detected by a camera module (e.g., third camera module (256)) corresponds to a pre-designated user gesture, as exemplarily illustrated in FIG. 5F. According to one embodiment of the present document, if it is determined that a user gesture detected by a camera module (e.g., third camera module (256)) corresponds to a pre-designated user gesture, as exemplarily illustrated in FIG. 5E, the wearable device (200) may turn at least one microphone (e.g., microphone module (247)) off. FIG. 5F is an exemplary diagram illustrating a control environment (e.g., a multi-modal environment) in which a wearable device (200) according to one embodiment of the present document can acquire both a user utterance and other user inputs other than the user utterance before identifying a user input (e.g., a user gesture). Referring to FIG. 5F, when a user's hand is detected by a camera module (e.g., a third camera module (256)), the wearable device (200) according to one embodiment of the present document can determine that the user intends to input a gesture and display a visual object (e.g., a hand-ray (570)) corresponding to the user's hand. The visual object (e.g., a hand-ray (1770)) according to one embodiment of the present document can be displayed so that its position moves in response to a change in the position of the user's hand. In FIG. 5f, a state before a user's gesture is input (e.g., when a user inputs a gesture of pointing a finger toward a virtual object (510) to input a swipe light gesture) is exemplarily illustrated.In FIG. 5F, since the user's gesture does not yet substantially completely correspond to the pre-designated gesture, a control environment (e.g., a multi-modal environment) capable of acquiring both the user's speech and other user inputs (e.g., user gestures) other than the user's speech may be provided to the user. The wearable device (200) according to one embodiment of the present document may display a designated area (e.g., a border (1712) area) of the virtual object in a second designated color to inform the user that the user's speech input can be acquired. The wearable device (200) according to one embodiment of the present document may move the display position of the virtual object (510) to the right according to the input user gesture when the user completes the gesture input (e.g., when a gesture of moving a finger pointing at the virtual object (510) to the right is detected). According to one embodiment of the present document, a wearable device (200) may switch the state of a microphone module (247) from an on state to an off state (e.g., switching to a single-modal control environment) based on detection of a user gesture. According to one embodiment of the present document, a wearable device (200) may display a designated area of ​​a virtual object (510) in a first designated color (e.g., gray), as illustrated in FIG. 5A, based on detection of a user gesture.

[0167] FIG. 18 is an exemplary drawing for explaining a function or operation of a wearable device (200) according to one embodiment of the present document to control a microphone module (247) according to a type of a detected user gesture (e.g., a first type corresponding to a pre-specified gesture or a second type not corresponding to a pre-specified gesture).

[0168] Referring to FIG. 18, a wearable device (200) according to one embodiment of the present document may set the state of a microphone (e.g., a microphone module (247)) to an on state in operation 1810. If it is determined that the user's gaze is gazing at a virtual object (510), the wearable device (200) according to one embodiment of the present document may set the state of a microphone (e.g., a microphone module (247)) to an on state.

[0169] A wearable device (200) according to one embodiment of the present document can determine whether a user gesture is detected in operation 1820. A wearable device (200) according to one embodiment of the present document can detect the movement of a user's hand using a camera module (250).

[0170] According to one embodiment of the present document, the wearable device (200) may determine whether a pre-designated gesture has been input at operation 1830. If, for example, the wearable device (200) according to one embodiment of the present document determines that a “swipe light” gesture (e.g., a first type gesture corresponding to a pre-designated gesture) has been input, the wearable device (200) may switch the state of the microphone from an on state to an off state at operation 640 (operation 630-Yes).

[0171] According to one embodiment of the present document, the wearable device (200) may determine whether the user is attempting to input a gesture if it is determined in operation 1850 that the input user gesture does not correspond to a pre-designated gesture (e.g., operation 1830—No). According to one embodiment of the present document, the wearable device (200) may determine a matching rate of the user's hand movement with a pre-designated gesture as illustrated in FIG. 5F, and if the determined matching rate is greater than or equal to a threshold rate (e.g., 50%), it may determine that the user is attempting to input a gesture.

[0172] According to one embodiment of the present document, the wearable device (200) can determine whether the same gesture is detected multiple times in operation 1860. According to one embodiment of the present document, the wearable device (200) can determine whether the movement of the user's hand being attempted in operation 1850 is a substantially identical movement repeatedly. However, according to one embodiment of the present document, operation 1860 may be omitted.

[0173] According to one embodiment of the present document, a wearable device (200) may provide a speech hint while maintaining the state of a microphone in an on state in operation 1870 when the same gesture is detected multiple times (e.g., operation 1860 - Yes). FIG. 19 is an exemplary drawing for explaining a function or operation of a wearable device (200) according to one embodiment of the present document providing a speech hint (1910) together with at least one indicator (1740). According to one embodiment of the present document, a wearable device (200) may provide a speech hint (1910) as illustrated in FIG. 19 while maintaining the state of a microphone in an on state in operation 1870 when the same gesture is detected multiple times (e.g., operation 1860 - Yes). In this case, the wearable device (200) according to one embodiment of the present document may process the acquired speech input in the wearable device (200) rather than in an external server (e.g., LLM server) when a speech input is acquired from the user. Alternatively, the wearable device (200) according to one embodiment of the present document may process the acquired user speech through a limited speech processing method. The speech hint (1910) according to one embodiment of the present document may include a hint that includes a speech command corresponding to a gesture that the user is attempting to input. For example, if the user only points at the virtual object (510) with his finger but does not move the finger in a specified direction, the wearable device (200) according to one embodiment of the present document may provide the user with a speech hint such as "Say swipe right." According to one embodiment of the present document, the wearable device (200) may, in operation 1880, keep the microphone in an on state without providing a speech hint (1910) if the same gesture is not detected multiple times (e.g., operation 1860-No).

[0174] FIG. 20 is an exemplary drawing for explaining a function or operation of controlling a microphone module (247) based on an input from an external device (e.g., a first external device (2110a), a second external device (2110b)) that is operable with the wearable device (200) according to one embodiment of the present document. FIG. 9a and FIG. 9b are exemplary drawings for explaining a type of an external device (e.g., a first external device (2110a), a second external device (2110b)) that is operable with the wearable device (200) according to one embodiment of the present document.

[0175] Referring to FIG. 20, a wearable device (200) according to an embodiment of the present document may determine whether an external device (e.g., a first external device (2110a) (e.g., a first controller) as illustrated in FIG. 21A and / or a second external device (2110b) (e.g., a second controller) as illustrated in FIG. 21B) operatively connected to the wearable device (200) exists when a user's gesture is not detected in operation 2010 (e.g., a user's hand is not detected or a movement of the user's hand is not detected, for example, operation 1820-No). The external devices (e.g., the first external device (2110a), the second external device (2110b)) according to an embodiment of the present document may include devices that are operatively connected to the wearable device (200) and are set to control a virtual object (510).

[0176] According to one embodiment of the present document, the wearable device (200) may determine, in operation 2020, whether a valid input is input through an external device (e.g., the first external device (2110a), the second external device (2110b)) if the external device (e.g., the first external device (2110a), the second external device (2110b)) is connected (e.g., operation 2010-Yes). According to one embodiment of the present document, the wearable device (200) may determine, for example, whether a button input provided in the external device (e.g., the first external device (2110a), the second external device (2110b)) is acquired.

[0177] According to one embodiment of the present document, the wearable device (200) may, in operation 2030, switch the state of the microphone to the off state if a valid input is obtained (e.g., operation 2020 - yes). According to one embodiment of the present document, the wearable device (200) may, in operation 2040, switch the state of the microphone to the on state if a valid input is not obtained (e.g., operation 2020 - no). In this case, when the wearable device (200) according to one embodiment of the present document obtains a speech input from a user, the wearable device (200) may process the user speech using a limited speech processing method.

[0192] FIG. 29 is an exemplary drawing for explaining the operation of a wearable device (200) according to one embodiment of the present document.

[0193] Referring to FIG. 29, a wearable device (200) according to an embodiment of the present document may determine, in operation 2910, whether there is an intention of a user input other than a user utterance. In operation 2920, the wearable device (200) according to an embodiment of the present document may keep at least one microphone turned on based on the result of the determination as to whether there is an intention of a user input other than a user utterance. In operation 2930, the wearable device (200) according to an embodiment of the present document may determine, while keeping at least one microphone turned on, whether another user input is input. The other user input according to an embodiment of the present document may include, for example, a user gesture and / or an input by an external controller.

[0194] The wearable device (200) according to one embodiment of the present document may turn off at least one microphone based on a determination as to whether another user input is input. For example, the wearable device (200) according to one embodiment of the present document may turn off at least one microphone when a designated user's gesture is detected. However, even if the designated user's gesture is not detected, if the wearable device (200) determines that the user intends to input a gesture (e.g., if the match ratio between the user's gesture and the pre-designated gesture is determined and the determined match ratio is greater than or equal to a threshold ratio (e.g., 50%) and / or if the camera module (247) detects that the user is holding an external device in his / her hand or if the controller detects that the user is pointing at a designated virtual object), the wearable device may keep at least one microphone on. In this case, if the user's speech is input, the user's speech may be processed using a limited speech processing method according to one embodiment of the present document.

[0195] FIG. 30 is an exemplary drawing for explaining a function or operation of a wearable device (200) performing limited speech processing according to one embodiment of the present document.

[0196] Referring to FIG. 30, a wearable device (200) according to an embodiment of the present document may detect a preparatory operation of a user gesture for controlling a first virtual object (510) and / or an external input device. In a state where a preparatory operation of a user gesture for controlling the first virtual object (510) and / or an external input device is detected, the wearable device (200) according to an embodiment of the present document may acquire a user's utterance (e.g., "select", "how do I press this?", or "can I copy the URL?"). In operation 3010, the wearable device (200) according to an embodiment of the present document may determine whether an utterance (e.g., "select", "click", "push", "input") having the same meaning as a command supported by a virtual object (e.g., the first virtual object (510)) has been acquired. According to one embodiment of the present document, if it is determined that an utterance (e.g., "select", "click", "push", "input") having the same meaning as a command supported by a virtual object (e.g., the first virtual object (510)) has been acquired (e.g., operation 3010 - Yes), the wearable device (200) may execute a command corresponding to the user's utterance (e.g., "select") in operation 3020. If it is determined that an utterance (e.g., "select", "click", "push", "input") having the same meaning as a command supported by a virtual object (e.g., the first virtual object (510)) has not been acquired (e.g., operation 3010 - No), the wearable device (200) may ignore the utterance command input through the wearable device (200) (e.g., not outputting a result for the utterance command).According to one embodiment of the present document, if an utterance is input, such as, for example, “How do I press this?” or “Can I copy the URL?”, in which the user’s intention is not clearly identified as the utterance itself, the wearable device (200) may determine that an utterance having the same meaning as a command supported by a virtual object (e.g., the first virtual object (510)) (e.g., “select,” “click,” “push,” “input”) has not been obtained. Alternatively, according to one embodiment of the present document, if the user’s utterance includes at least one slang, the wearable device (200) may determine that an utterance having the same meaning as a command supported by a virtual object (e.g., the first virtual object (510)) (e.g., “select,” “click,” “push,” “input”) has not been obtained. According to one embodiment of the present document, a wearable device (200) may process a user's speech using a limited speech processing method when a user gesture for controlling a first virtual object (510) is preparatory and / or an external input device is detected. In this way, by processing the user's speech using a limited speech processing method, the processing load of the processor may be reduced, thereby achieving a technical effect of reducing power consumption of the wearable device and / or an external electronic device (e.g., an LLM server).

[0197] FIG. 31 is an exemplary drawing for explaining a function or operation of a wearable device (200) to process a user utterance input through the wearable device (200) when there is no external device connected to the wearable device (200) according to one embodiment of the present document and no user gesture (e.g., a preparatory action of a gesture) is detected.

[0198] Referring to FIG. 31, when there is no external device connected to the wearable device (200) according to one embodiment of the present document and no user gesture (e.g., a preparatory action of a gesture) is detected, the user's utterance (e.g., "Can the URL be copied?") can be acquired. The wearable device (200) according to one embodiment of the present document can determine, in operation 3110, whether an utterance (e.g., "select", "click", "push", "input") having the same meaning as a command supported by a virtual object (e.g., a first virtual object (510)) has been acquired. According to one embodiment of the present document, if it is determined that an utterance (e.g., "select", "click", "push", "input") having the same meaning as a command supported by a virtual object (e.g., the first virtual object (510)) has been acquired (e.g., operation 3010-Yes), the wearable device (200) may execute a command corresponding to the user's utterance (e.g., "select") in operation 3120. If it is determined that an utterance (e.g., "select", "click", "push", "input") having the same meaning as a command supported by a virtual object (e.g., the first virtual object (510)) has not been acquired in operation 3130, the wearable device (200) may determine whether a virtual object related to the utterance command exists within the field of view. For example, the wearable device (200) according to one embodiment of the present document may determine whether a virtual object including a URL address exists within the field of view of the wearable device (200) when a user utterance such as “Can you copy the URL?” is obtained. In operation 3140, the wearable device (200) according to one embodiment of the present document may execute a command corresponding to the user utterance when a virtual object related to the utterance command exists within the field of view (e.g., when a virtual object including a URL address exists).In this case, the wearable device (200) and / or the external electronic device (e.g., LLM server) according to one embodiment of the present document can determine the user's speech intention and execute a command corresponding to the user's speech based on the determined speech intention. In operation 3150, the wearable device (200) according to one embodiment of the present document can output a guide message guiding the user to select a virtual object related to the user's speech if there is no virtual object related to the speech command within the field of view. In this way, according to one embodiment of the present document, if there is no external device connected to the wearable device (200) and the user's gesture (e.g., a preparatory action of the gesture) is not detected, the user's speech input can be determined as the main input and the user's speech input can be processed.

[0199] FIG. 32a and FIG. 32b are exemplary drawings for explaining a function or operation of a wearable device (200) according to one embodiment of the present document to process an input user's speech in a limited speech processing manner based on the intention of the user's gesture input and / or the connection status of an external electronic device.

[0200] Referring to FIGS. 32A and 32B , the wearable device (200) according to one embodiment of the present document may set the microphone to an on state in operation 3205. The wearable device (200) according to one embodiment of the present document may determine whether the user intends to input a gesture in operation 3210. The wearable device (200) according to one embodiment of the present document may determine whether a part of the user's body (e.g., the user's hand) is detected using a camera module (e.g., the third camera module (256)). The wearable device (200) according to one embodiment of the present document may determine that the user intends to input a specified gesture when a part of the user's body (e.g., the user's hand) is detected. A wearable device (200) according to one embodiment of the present document can determine a matching rate between a user's hand movement and a pre-designated gesture as illustrated in FIG. 5E, and if the determined matching rate is greater than or equal to a threshold rate (e.g., 50%), determine that the user is attempting a gesture input (e.g., determine that there is an intention to input a gesture). A wearable device (200) according to one embodiment of the present document can determine that there is an intention to input a user input if it is detected through a camera module (247) that the user is holding an external device in his / her hand, or if the user is pointing at a virtual object designated through a controller.

[0201] According to one embodiment of the present document, the wearable device (200) may determine whether a user utterance is input at operation 3215. According to one embodiment of the present document, if a user utterance is input at operation 3220 (e.g., if a user utterance is input within a specified time), the wearable device (200) may keep the microphone on and process the user utterance using a limited utterance processing method. According to one embodiment of the present document, if a user utterance is not input at operation 3225 (e.g., if a user utterance is not input within a specified time), the wearable device (200) may determine that the user's intention is to control a virtual object through a gesture input, and may switch the microphone to an off state. According to one embodiment of the present document, if the user does not intend a gesture input at operation 3230, the wearable device (200) may determine whether another input device is connected to the wearable device. According to one embodiment of the present document, the wearable device (200) may determine, in operation 3235, whether a user's speech is input. According to one embodiment of the present document, if the user's speech is input (e.g., if the user's speech is input within a specified time), in operation 3240, the wearable device (200) may keep the microphone on and process the user's speech using a limited speech processing method. According to one embodiment of the present document, if the user's speech is not input (e.g., if the user's speech is not input within a specified time), in operation 3225, the wearable device (200) may determine that the user's intention is to control a virtual object through a gesture input, and may switch the microphone to an off state.

[0202] According to one embodiment of the present document, the wearable device (200), if it is determined that no other input device is connected in operation 3245, can determine whether the user is moving his / her mouth. According to one embodiment of the present document, if it is determined that the user is moving his / her mouth in operation 3255, the wearable device (200) can keep the microphone on and process the speech command input through the wearable device (200). According to one embodiment of the present document, if it is determined that the user is not moving his / her mouth in operation 3250, the wearable device (200) can determine the sound input through the wearable device (200) as noise and limit the processing of the input sound.

[0203] According to one embodiment of the present document, a wearable device (200) includes a display module, at least one microphone, at least one camera, at least one processor, and a memory, and the memory may be configured to store instructions that, when executed by the at least one processor, cause the wearable device to display at least one virtual object through the display module, switch the at least one microphone from an OFF state to an ON state based on an interaction between the at least one virtual object and a user wearing the wearable device, determine whether a gesture of the user is detected using the at least one camera while the at least one microphone is in the ON state, determine whether the gesture corresponds to a gesture designated in advance for controlling the virtual object based on the determination as to whether the gesture corresponds to the predefined gesture, and maintain the at least one microphone in the ON state or switch the at least one microphone to the OFF state based on the determination as to whether the gesture corresponds to the predefined gesture.
