For example, in response to (or based on) an input indicating selection of all of the external electronic devices 121 and 122 of FIGS. 1A and 1B, the wearable device may identify the first set and the second set of functions applicable to each of the external electronic devices 121 and 122, based on the categories 423 and 421 of FIG. 4 in which each of the external electronic devices 121 and 122 is classified. Intersection of the first set and the second set may include functions commonly applicable to the external electronic devices 121 and 122 of FIGS. 1A and 1B as an element. The wearable device according to an embodiment may display a screen for execution of at least one function included in the intersection, in response to (or based on) the input.

An example operation of the wearable device based on the intersection of sets of functions applicable to each of the plurality of external electronic devices has been described, but an embodiment is not limited thereto. For example, in response to (or based on) the input indicating selection of the plurality of external electronic devices, the wearable device may identify the lowest category including all of the plurality of external electronic devices within hierarchical categories. Like the example, in a state of receiving an input indicating selection of all of the external electronic devices 121 and 122 of FIG. 1A and 1B, the wearable device may identify a higher category (upper category) of each of the categories 423 and 421 of FIG. 4 in which each of the external electronic devices 121 and 122 is classified. Referring to FIG. 4, the category 420 including all of the categories 423 and 421 may be a lowest category from among the categories 410 and 420 including all the categories 423 and 421. The wearable device may identify at least one function commonly applicable to the external electronic devices 121 and 122 selected by the input, based on the category 420.

The wearable device according to an embodiment may guide a user's selection based on homogeneity of external electronic devices, based on the hierarchical categories. For example, in response to (or based on) an input of selecting at least two external electronic devices, the wearable device may guide selection of another external electronic device different from the external electronic devices, based on union or a higher category of categories corresponding to each of the external electronic devices selected by the input. Like the example, in a state of receiving the input indicating selection of all of the external electronic devices 121 and 122 of FIGS. 1A and 1B, the wearable device may identify another external electronic device included in a higher category (upper category) of each of the categories 423 and 421 of FIG. 4 in which each of the external electronic devices 121 and 122 is classified. The other external electronic device may include, for example, an external electronic device included in the category 420 that is a higher category (upper category) of the categories 421 and 423 of FIG. 4, such as the external electronic device 123 of FIGS. 1A and 1B. Within the example, the wearable device may guide additional selection of the external electronic device 123 of FIGS. 1A and 1B.

As described above, the wearable device according to an embodiment may obtain hierarchical categories (e.g., the categories 410, 420, 421, 422, 423, 430, 431, 433, 434, 441, 442, 450, and 451) for classifying a plurality of external electronic devices, based on metadata on the plurality of external electronic devices connected to the wearable device. Based on the hierarchical categories, the wearable device may identify at least one function applicable common to the external electronic devices. For example, in addition to a function of turning on or off external electronic devices, the wearable device may identify another function commonly applicable to the external electronic devices. The wearable device may support the user to collectively control the plurality of external electronic devices in addition to the function of turning on or off the plurality of external electronic devices, by displaying a screen for execution of the other function.

Hereinafter, an operation of receiving an input indicating that the wearable device according to an embodiment adds an external electronic device will be described with reference to FIGS. 5A to 5C.

FIGS. 5A to 5C illustrate an example of an operation in which a wearable device according to an embodiment receives an input indicating a connection between an external electronic device and the wearable device. The wearable device of FIGS. 5A to 5C may be an example of the wearable device 101 of FIGS. 1A and 1B and/or the wearable device of FIGS. 2 to 4. For example, the wearable device 101 of FIG. 1 may include the wearable device of FIGS. 5A to 5C. For example, a FoV 110 of FIGS. 5A to 5C may correspond to the FoV 110 of FIGS. 1A and 1B.

The wearable device according to an embodiment may identify one or more external electronic devices included in the FoV 110 by using a camera (e.g., the camera 240 of FIG. 2). For example, the wearable device may identify the one or more external electronic devices included in the FoV 110, based on object detection and/or object recognition. The wearable device may extract one or more feature points from an image of the FoV 110 obtained from the camera. The wearable device may identify the one or more external electronic devices based on the one or more feature points. The wearable device may identify the one or more external electronic devices by using a neural network trained to identify an external electronic device from the image.

The wearable device according to an embodiment may receive an input for notifying a location of at least one external electronic device (e.g., an external electronic device 512) within the FoV 110. For example, the wearable device may obtain the location of the external electronic device from a user, independently of the object detection and/or the object recognition. Hereinafter, an operation in which the wearable device according to an embodiment identifies a location of the external electronic device 512 based on a user input will be described with reference to FIGS. 5A to 5C.

In a state 510 of FIG. 5A, the wearable device may display a visual object 514 for receiving a location of the external electronic device 512, superimposed within the FoV 110. The external electronic device 512 may be identified by the wearable device through communication circuitry (e.g., the communication circuitry 250 of FIG. 2) in the state 510 and/or before the state 510. The visual object 514 may be displayed within a display (e.g., the display 230 of FIG. 2) at least partially superimposed with the FoV 110. The wearable device may display a translucent visual object 514 based on a preset alpha value. The wearable device may display preset text (e.g., “take place”) for guiding that the location of the external electronic device 512 may be selected within the visual object 514. The visual object 514 may be referred to as an anchor for selecting an external electronic device or selecting a location of the external electronic device.

The wearable device according to an embodiment may receive an input for moving the visual object 514. For example, the wearable device may receive the input based on a user's motion to be described later with reference to FIGS. 6A and 6B. For example, the wearable device may receive the input based on a user's speech to be described later with reference to FIGS. 7A and 7B. In the state 510 of FIG. 5A, the wearable device may receive an input indicating a movement of the visual object 514 along a path 516. For example, the user may move the visual object 514, so that the visual object 514 may be superimposed on the external electronic device 512 included in the FoV 110.

A state 520 of FIG. 5B may be a state after the wearable device receives the input indicating the movement of the visual object 514. Referring to FIG. 5B, in response to (or based on) the input, the wearable device may display options 522, 524, and 526 for selecting a type of the external electronic device 512. For example, the options 522, 524, and 526 may be displayed by the wearable device to receive a category of the external electronic device 512 superimposed with the visual object 514 within the FoV 110 from the user.

Referring to FIG. 5B, the option 522 may include an icon for receiving an input indicating that the external electronic device 512 is classified as stand-alone lighting equipment (e.g., the lighting equipment classified into the category 421 of FIG. 4). The option 524 may include an icon for receiving an input indicating that the external electronic device 512 is lighting equipment (e.g., the lighting equipment classified into the category 422 of FIG. 4) fixed to the ceiling. The option 526 may include an icon for receiving an input indicating that the external electronic device 512 is a light bulb (e.g., the lighting equipment classified into the category 423 of FIG. 4).

In an embodiment, in response to (or based on) an input indicating selection of any one of the options 522, 524, and 526, the wearable device may classify the external electronic device 512 into at least one of the hierarchical categories. Hereinafter, it is assumed that the wearable device has received an input indicating selection of the option 522 from the user in the state 520 of FIG. 5B.

A state 530 of FIG. 5C may be a state in which the wearable device displays a screen 534 for controlling the external electronic device 512 after identifying the external electronic device 512 based on the states 510 and 520 of FIGS. 5A to 5B. For example, in response to (or based on) an input indicating selection of the external electronic device 512, the wearable device may display a visual object 532 to indicate that the external electronic device 512 is selected, in response to (or based on) the input. Referring to FIG. 5C, an example of the visual object 532 based on a rectangular line is illustrated, but an embodiment is not limited thereto. For example, the visual object 532 may have a shape of an outline of the external electronic device 512. For example, the visual object 532 may have a shape of a polygon that at least partially overlaps the external electronic device 512.

The wearable device according to an embodiment may display the screen 534 on at least a portion of the FoV 110, in response to (or based on) an input indicating selection of the external electronic device 512. The wearable device may display one or more functions applicable to the external electronic device 512 selected by the input within the screen 534. The one or more functions applicable to the external electronic device 512 may be identified based on metadata on the external electronic device 512 and/or one or more categories in which the external electronic device 512 is included.

Referring to FIG. 5C, the wearable device may display an icon 534-1 and/or text 534-2 for indicating the type of the external electronic device 512 within the screen 534. The wearable device may display a button 534-3 for toggling the external electronic device 512 between an active state and an inactive state within the screen 534. The wearable device may display a visual object 534-4 such as a slider for adjusting the amount of light of the external electronic device 512 within the screen 534. The wearable device may display a visual object 534-5 such as a palette for adjusting a color of light outputted from the external electronic device 512 within the screen 534. The wearable device may display a visual object 534-6 such as a slider for adjusting a color temperature within the screen 534. The wearable device according to an embodiment may control the external electronic device 512 in response to (or based on) an input based on the screen 534. For example, the wearable device may transmit a signal indicating the input to the external electronic device 512, in response to (or based on) the input.

Although an example operation of the wearable device related to the external electronic device 512 has been described, an embodiment is not limited thereto. For example, based on an input indicating selection of another external electronic device that is viewable through the FoV 110 and different from the external electronic device 512, the wearable device may display a screen for executing functions applicable to the other external electronic device, similar to the screen 534. For example, in response to (or based on) an input indicating selection of at least one of the visual objects 151, 152, and 153 superimposed on at least a portion of the FoV 110, the wearable device may display a screen for executing functions applicable to at least one external electronic device corresponding to at least one visual object selected by the input.

As described above, the wearable device according to an embodiment may display a UI for controlling an external electronic device, such as the screen 534, based on an input indicating selection of the external electronic device. In response to (or based on) the input based on the UI, the wearable device may transmit a signal for controlling the external electronic device. When the number of external electronic devices selected by the user increases to two or more, the wearable device may display functions commonly applicable to external electronic devices selected by the user, by changing the UI. In an embodiment, the wearable device may guide the user additional selection of an external electronic device, based on homogeneity of external electronic devices selected by the user.

Hereinafter, example operations of receiving an input indicating that a wearable device according to an embodiment selects two or more external electronic devices will be described with reference to FIGS. 6A and 6B and/or 7A and 7B.

FIGS. 6A and 6B illustrate an example of an operation in which a wearable device 101 according to an embodiment receives an input indicating selection of at least one of external electronic devices, based on a user's motion. The wearable device 101 of FIGS. 6A and 6B may be an example of the wearable device 101 of FIG. 1, and the wearable device of FIGS. 2 to 4 and/or FIGS. 5A to 5C. For example, the wearable device 101 of FIG. 1 may include the wearable device 101 of FIGS. 6A and 6B. A FoV 110 of FIGS. 6A to 6C may include the FoV 110 of FIGS. 1A and 1B.

States 610 and 620 of FIGS. 6A and 6B may be a state during which the wearable device has entered a mode (e.g., a multi-selection mode) for receiving an input indicating selection of one or more external electronic devices. For example, the wearable device may enter the mode in response to (or based on) an input (e.g., long-press) pressing the wearable device by exceeding preset duration, or an input (e.g., double-tap) tapping the wearable device at a preset number (e.g., two times) within preset duration.

FIG. 6A illustrates an example state 610 in which the wearable device 101 according to an embodiment identifies a motion of a user's body part (e.g., a hand 612). The wearable device 101 may obtain an image including the hand 612 by using a camera (e.g., the camera 240 of FIG. 2). The wearable device 101 may obtain data indicating the motion of the hand 612, based on a change in a position and/or a size of the hand 612 within the obtained image. The data may include a path of the hand 612 and/or a finger included in the hand 612.

The wearable device 101 according to an embodiment may receive an input indicating selection of one or more external electronic devices, based on a path of a body part such as the hand 612. In a state 610 of FIG. 6A, the wearable device 101 may display a visual object 614 for indicating the path of the hand 612 within the FoV 110. The visual object 614 may indicate a path tracked based on a line while the wearable device tracks the path of the hand 612. The wearable device 101 according to an embodiment may select external electronic devices 121 and 122 included in a path within the FoV 110, based on identifying the path having a shape of a closed curve such as the visual object 614. For example, the motion of the hand 612 moving along the path having the shape of the closed curve, such as the visual object 614, may be a gesture for selecting the external electronic devices 121 and 122.

FIG. 6B illustrates an example state 620 in which the wearable device 101 according to an embodiment receives an input indicating selection of at least one external electronic device, based on an external electronic device such as a pointing device 622. The pointing device 622 may be connected to the wearable device 101 by wire or wirelessly to receive the user's gesture wearing the wearable device 101. The user may control the wearable device 101 by moving the pointing device 622 or pressing a button of the pointing device 622. For example, the pointing device 622 may be an electronic device for remotely controlling another electronic device (e.g., the wearable device 101) different from the pointing device 622, such as the category 450 of FIG. 4.

The wearable device 101 according to an embodiment may receive an input detected by the pointing device 622 and indicating selection of at least one external electronic device. Referring to FIG. 6B, the wearable device 101 may display a visual object 624 indicating a path of the pointing device 622. The wearable device 101 may receive an input indicating selection of external electronic devices 121, 122, and 131 included in a closed curve within the FoV 110, based on the visual object 624 having a shape of the closed curve.

The wearable device 101 may receive an input indicating selection of a plurality of external electronic devices by using the pointing device 622 and/or the hand 612. The wearable device 101 may also receive an input indicating exclusion of at least one of the plurality of pre-selected external electronic devices. For example, the wearable device 101 may identify a motion of the pointing device 622 moving along a path of a visual object 626 after receiving a first input indicating selection of the external electronic devices 121, 122, and 131, such as the visual object 624. The wearable device 101 may receive a second input indicating exclusion of the external electronic device 131 specified by the path of the visual object 626, based on the motion of the pointing device 622 moving along the path of the visual object 626. After sequentially receiving the first input and the second input, the wearable device 101 may determine that the external electronic devices 121 and 122 are selected by the user.

As described above, the wearable device 101 according to an embodiment may receive an input indicating selection of one or more external electronic devices, based on the motion of the user's hand 612. The wearable device 101 may identify functions commonly applicable to a plurality of external electronic devices, based on identifying that the plurality of external electronic devices are selected by the input. The wearable device 101 identifying the functions commonly applicable to the plurality of external electronic devices may be performed based on hierarchical categories (e.g., the categories of FIG. 4). The wearable device 101 may support the user to collectively control of the plurality of external electronic devices based on the functions, by displaying the identified functions within the FoV 110.

The wearable device 101 receiving an input indicating selection of the external electronic devices is not limited to example operations of FIGS. 6A and 6B. Hereinafter, an operation in which the wearable device 101 according to an embodiment receives an input indicating selection of external electronic devices, based on a motion of the wearable device 101 and/or a user's speech will be described with reference to FIGS. 7A and 7B.

FIGS. 7A and 7B illustrate an example of an operation in which a wearable device 101 according to an embodiment receives an input indicating selection of at least one of external electronic devices, based on a user's motion and speech. The wearable device 101 of FIG. 1 may include the wearable device 101 of FIGS. 7A and 7B. The wearable device 101 of FIGS. 7A and 7B may be an example of the wearable device of FIGS. 2 to 4 and 5A to 5C, and/or the wearable device 101 of FIGS. 6A and 6B. Similar to the states 610 and 620 of FIGS. 6A and 6B, states 710 and 720 of FIGS. 7A and 7B may be a state during which the wearable device has entered a mode for receiving an input indicating selection of one or more external electronic devices.

The wearable device 101 according to an embodiment may include a sensor (e.g., the sensor 260 of FIG. 2) to track an eye gaze and/or a motion of a head of the user wearing the wearable device 101. The wearable device 101 may include a microphone (e.g., the microphone 270 of FIG. 2) to receive an audio signal. The wearable device 101 may extract a speech 714 from the audio signal. The wearable device 101 extracting the speech 714 from the audio signal may be performed, based on an algorithm and/or a neural network for speech-to-text (STT).

The wearable device 101 according to an embodiment may identify a preset keyword from the audio signal. For example, the wearable device 101 may identify a preset keyword in the speech 714. The preset keyword may include a demonstrative pronoun, such as a keyword 716 of FIG. 7A. The wearable device 101 may identify a motion (e.g., a change in the user's eye gaze and/or a motion of the user's head) of the user wearing the wearable device 101, in response to (or based on) identifying a noun for selecting one or more external electronic devices from the speech 714, such as the demonstrative pronoun.

Referring to FIG. 7A, in response to (or based on) identifying a preset keyword (e.g., the keyword 716) from the audio signal, the wearable device may receive an input indicating selection of at least one external electronic device, based on a time section in which the preset keyword is identified, the user's eye gaze detected by the sensor, and/or the motion of the user's head. For example, the wearable device 101 may obtain data indicating the user's eye gaze and/or the motion of the wearable device 101 within the time section in which the keyword 716 is received. The wearable device 101 may display a visual object 712, superimposed within the FoV 110, based on the data obtained within the time section. For example, the visual object 712 may indicate a path of the wearable device 101 by the user's eye gaze and/or the motion of the user's head within the time section.

The wearable device 101 according to an embodiment may receive an input indicating selection of one or more external electronic devices, based on the visual object 712 indicating the received motion within the time section in which the keyword 716 is received. For example, the wearable device 101 may determine an external electronic device 121 and an external electronic device corresponding to a visual object 153, which are included in a closed curve indicated by the visual object 712 within the FoV 110, as external electronic devices selected by the user.

The wearable device 101 according to an embodiment may collectively control external electronic devices selected by the keyword 716 within the speech 714, based on another keyword that is included in the speech 714 and different from the keyword 716. Referring to FIG. 7A, in response to (or based on) receiving the speech 714 such as “turn all of those off”, the wearable device 101 may identify a keyword (e.g., “all of those”) for selecting external electronic devices within the speech 714 and a keyword (e.g., “turn off”) for selecting a function to be commonly applied to the external electronic devices. For example, in response to (or based on) receiving the speech 714, the wearable device 101 may collectively turn off the external electronic devices (e.g., the external electronic device 121, and the external electronic device corresponding to the visual object 153) selected by the keyword 716 within the speech 714.

FIG. 7B illustrates an example of a timing diagram 720 indicating a function in which the wearable device 101 according to an embodiment executes based on keywords included in a speech while identifying the speech (e.g., the speech 714 of FIG. 7A) from an audio signal. The wearable device 101 may obtain text from the audio signal based on the STT. The wearable device 101 may execute a specific function in response to (or based on) identifying a keyword indicating the specific function (e.g., a function of selecting the one or more external electronic devices described above with reference to FIG. 7A) within the text.

Referring to FIG. 7B, the wearable device 101 may obtain text indicating a speech from the audio signal, from a time point t1. For example, the wearable device 101 may perform conversion (e.g., STT) between the speech and the text within a time section 721 starting from the time point t1. Referring to FIG. 7B, a preset keyword notifying the start of a voice command for controlling the wearable device 101 may be identified within a time section 722 between the time point t1 and a time point t2. For example, the preset keyword notifying the start of the voice command may be “Hi Bixby” or may include text (e.g., “Hi (text)”) inputted by the user.

Referring to FIG. 7B, the wearable device 101 may obtain text indicating the voice command continued after the preset keyword from the time point t2, based on identifying the preset keyword within the time section 722. For example, the wearable device 101 may obtain the voice command from the audio signal within a time section 723 after the time point t2. A time section 725 after the time point t2 may be a time section in which the wearable device 101 performs an operation indicated by the voice command.

Referring to FIG. 7B, the wearable device 101 may identify a keyword indicating selection of one or more external electronic devices, such as a demonstrative pronoun, from the text, within a time section 724 between a time point t3 and a time point t4. Within the time section 724, the wearable device 101 may detect the user's motion, as described above with reference to FIG. 7A. The wearable device 101 may identify one or more external electronic devices based on the detected motion.

Referring to FIG. 7B, within the time section 723 of receiving the voice command, the wearable device 101 may identify a function to be executed by one or more external electronic devices selected by the time section 724, based on a keyword identified within a remaining time section (e.g., a time section between the time point t2 to the time point t3, and a time section between the time point t4 to a time point t5) excluding the time section 724 of receiving the demonstrative pronoun. For example, the wearable device 101 may transmit a signal for deactivation to one or more external electronic devices selected based on the time section 724, in response to (or based on) identifying a preset keyword for the deactivation of the external electronic device within the remaining time section, such as “turn off”. In response to (or based on) the signal, the one or more external electronic devices may be collectively deactivated. Transmitting the signal by the wearable device 101 may be performed after the time point t5 within the time section 725.

Although an embodiment for identifying a speech in English has been described, the embodiment is not limited thereto. For example, the wearable device 101 may control one or more external electronic devices connected to the wearable device 101 based on a speech such as “Turn all of those off!”.

As described above, the wearable device 101 according to an embodiment may receive an input that indicates selection of one or more external electronic devices and collective control of the selected one or more external electronic devices by using an audio signal and a user's motion. The wearable device 101 may collectively control the one or more external electronic devices based on the input. Although an operation in which the wearable device 101 collectively deactivates the external electronic devices based on the user's speech has been described, an embodiment is not limited thereto. The wearable device 101 may transmit a signal to execute a function corresponding to text to a plurality of external electronic devices, in response to (or based on) identifying the text from the user's speech, wherein the text corresponds to any one of functions commonly applicable to a plurality of external electronic devices selected by the user.

Hereinafter, referring to FIGS. 8A to 8C, an operation in which a wearable device 101 according to an embodiment guides selection of another external electronic device similar to external electronic devices selected by a user, based on the external electronic devices selected the user's motion and/or speech described above with reference to FIGS. 6A and 6B and/or 7A and 7B will be described.

FIGS. 8A to 8C illustrate an example of an operation in which a wearable device according to an embodiment displays a visual object for guiding selection of at least one external electronic device. The wearable device 101 of FIG. 1 may include the wearable device of FIGS. 8A to 8C. The wearable device of FIGS. 8A to 8C may be an example of the wearable device of FIGS. 2 to 4, and 5A to 5C, and/or the wearable device 101 of FIGS. 6A and 6B, and 7A and 7B.

FIG. 8A illustrates a state 810 after the wearable device according to an embodiment receives an input indicating selection of an external electronic device 121 within a FoV 110. The input may be received based on processing of the user's motion and/or speech described above with reference to FIGS. 6A and 6B and/or 7A and 7B. In response to (or based on) the input indicating the selection of the external electronic device 121, the wearable device may display a visual object 815, superimposed on the external electronic device 121 within the FoV 110. An example in which the wearable device displays the visual object 815 having a shape of an outline within the FoV 110 of the external electronic device 121 is illustrated, but an embodiment is not limited thereto. For example, the visual object 815 may have a shape and/or color for emphasizing the external electronic device 121 within the FoV 110.

In the state 810 of displaying the visual object 815 of FIG. 8A, the wearable device may receive an input indicating selection of another external electronic device different from the external electronic device 121 corresponding to the visual object 815. For example, the wearable device may receive an input indicating selection of the other external electronic device (e.g., external electronic devices corresponding to each of external electronic devices 122, 123, 131, 132, 141, 142, 161, and 171, and visual objects 151, 152, and 153) excluding the external electronic device 121.

A state 820 of FIG. 8B may illustrate a state after receiving the input indicating selection of the visual object 152 in the state 810 of FIG. 8A. The wearable device according to an embodiment may visualize that the visual object 152 is selected, in response to (or based on) an input indicating selection of the visual object 152. For example, the wearable device may indicate that the visual object 152 is selected, by displaying the visual object 821, superimposed on the visual object 152.

In the state 820 of FIG. 8B, the wearable device according to an embodiment may display at least one visual object (e.g., visual objects 822, 823, and 824) guiding selection of another external electronic device similar to a plurality of external electronic devices (e.g., the external electronic device 121 and an external electronic device corresponding to the visual object 152) selected by the user. Based on identifying that the plurality of external electronic devices (e.g., the external electronic device 121 and the external electronic device corresponding to the visual object 152) have been selected by the user, the wearable device may identify a category of each of the plurality of external electronic devices. For example, the wearable device may identify a category (e.g., the category 421) of the external electronic device 121 on which the visual object 815 is superimposed, from among the hierarchical categories of FIG. 4. The wearable device may identify a category (e.g., the category 423) of the external electronic device on which the visual object 152 is superimposed.

The wearable device according to an embodiment may identify external electronic devices (e.g., an external electronic device that is homogeneous with the external electronic devices selected by the user) within a category including all the external electronic devices selected by the user. For example, the external electronic devices identified by the wearable device may be union of categories in which each of the external electronic devices selected by the user is classified. For example, the external electronic devices identified by the wearable device may be identified based on a higher category that the categories have in common.

In an embodiment of FIG. 8B in which the external electronic device 121 and an external electronic device corresponding to the visual object 152 are selected by the user, the wearable device may identify other external electronic devices classified into the categories 421 and 423 of FIG. 4. For example, the wearable device may identify another external electronic device (e.g., an external electronic device corresponding to the visual object 153 and the external electronic device 122) classified into the same category as the external electronic device 121 selected by the user. For example, the wearable device may identify another external electronic device (e.g., an external electronic device corresponding to the visual object 151 and the external electronic devices 122) classified into the same category as the external electronic device corresponding to the visual object 152 selected by the user.

The wearable device according to an embodiment may display a visual object indicating another external electronic device (e.g., an external electronic device that is homogeneous with external electronic devices selected by the user) similar to external electronic devices selected by the user. The wearable device may display the visual object, as associated with the other external electronic device. The visual object may be displayed based on a different shape and/or a color from the visual objects 815 and 821 displayed as associated with the external electronic devices selected by the user, to guide selection of the other external electronic device.

Referring to FIG. 8B, the wearable device may display a visual object 825, as associated with another external electronic device (e.g., an external electronic device corresponding to the visual object 153) classified into the same category as the external electronic device 121 selected by the user. The visual object 815 displayed as associated with the external electronic device 121 may be displayed based on a first type indicating that it is selected by the user. In an embodiment, the visual object 825 displayed as associated with the visual object 153 may be displayed, based on a second type, which is different from the first type, for guiding the user's additional selection.

Referring to FIG. 8B, the wearable device may display the visual objects 823 and 822 by superimposing with another electronic device (e.g., the external electronic devices 122 and an external electronic device corresponding to the visual object 151) classified into the same category as an electronic device that is selected by the user and corresponds to the visual object 152. The wearable device according to an embodiment may emphasize other electronic devices similar to the external electronic devices selected by the user within the FoV 110, by displaying the visual objects 822, 823, and 825 together with the visual objects 815, and 821. The wearable device according to an embodiment may display the visual object 824 for selecting all the other external electronic devices. The visual object 824 may include preset text (e.g., “selecting a remaining object”) for guiding selection of all the other external electronic devices.

A state 830 of FIG. 8C may illustrate a state after receiving an input indicating the selection of the visual object 824 in the state 820 of FIG. 8B. In response to (or based on) the input, the wearable device may replace the visual objects 822, 823, and 825, which were displayed for guiding the user's selection in the state 820 of FIG. 8B with visual objects 831, 832, and 833 for indicating that it is selected by the user. In the state 830 of FIG. 8C, the wearable device may determine that all of the external electronic devices 121 and 122 and external electronic devices corresponding to the visual objects 151, 152, and 153 are selected by the user.

As described above, the wearable device according to an embodiment may display the first type of the visual objects 815 and 821 indicating that the plurality of external electronic devices is selected, based on the input indicating the selection of the plurality of external electronic devices. While displaying the first type of visual objects 815, and 821, the wearable device may display a visual object (e.g., the visual objects 822, 823, 824, and 825), which is different from the first type, for guiding selection of another external electronic device that is homogeneous with the plurality of external electronic devices. The wearable device may notify the user of another external electronic device that is homogeneous with the plurality of external electronic devices, or may guide selection of the other external electronic device, by using a visual object different from the first type.

Hereinafter, referring to FIGS. 9A and 9B and/or 10A to 10C, an example of an operation in which a wearable device displays a screen for execution of functions commonly applicable to a plurality of external electronic devices selected by a user or visualizes data obtained from the plurality of external electronic devices will be described.

FIGS. 9A and 9B illustrate an example of a screen in which a wearable device according to an embodiment displays based on a category of an external electronic device selected by a user. The wearable device 101 of FIG. 1 may include the wearable device of FIGS. 9A and 9B. The wearable device of FIGS. 9A and 9B may be an example of the wearable device of FIGS. 2 to 4, and 5A to 5C, and/or the wearable device 101 of FIGS. 6A and 6B, 7A and 7B, and 8A to 8C.

FIG. 9A illustrates a state 910 in which the wearable device displays a screen 911 in response to (or based on) an input indicating selection of an external electronic device 121 and an external electronic device corresponding to a visual object 152. The input may be received based on the user's motion and/or speech described above with reference to FIGS. 6A and 6B and/or 7A and 7B. In response to (or based on) the input, the wearable device may display visual objects 901 and 902 for indicating external electronic devices (e.g., the electronic device 121 and the electronic device corresponding the visual object 152) selected by the user, as associated with the external electronic devices.

In the state 910 of FIG. 9A, the wearable device may identify functions commonly applicable to the external electronic devices selected by the user. For example, the wearable device may identify the functions commonly applicable to the external electronic devices, based on the metadata of external electronic devices selected by the user and/or categories of each of the external electronic devices. The wearable device according to an embodiment may display the screen 911 for executing functions commonly applicable to the external electronic devices within the FoV 110.

Referring to FIG. 9A, the wearable device according to an embodiment may display visual objects 912, 913, 914, and 915 for executing the functions commonly applicable to the external electronic devices selected by the user within the screen 911. For example, the wearable device may display a button, such as the visual object 912, for activating or deactivating the external electronic devices collectively within the screen 911. Based on that all the external electronic devices selected by the user supports an adjustment of the amount of light by the user, the wearable device may display the visual object 913 including a slider for adjusting the amount of light of all the external electronic devices within the screen 911. The wearable device may display the visual object 914 including a palette for adjusting colors of all the external electronic devices within the screen 911. The wearable device may display a list of one or more colors commonly supported by the external devices within the visual object 914. The wearable device may display the visual object 915 for adjusting a color temperature of all the external electronic devices within the screen 911. In the state 910 of FIG. 9A, the wearable device may display the visual objects 913, 914, and 915 for collective adjust of the amount of light, the color, and the color temperature, based on identifying that all the external electronic devices selected by the user support functions to adjust the amount of light, the color, and the color temperature.

In the state 910 of FIG. 9A, the wearable device may control all the external electronic devices selected by the user, based on an input related to the screen 911. In response to (or based on) an input for any one of the visual objects 912, 913, 914, and 915 within the screen 911, the wearable device may request execution of a function mapped to a visual object selected by the input to the external electronic device. For example, when receiving an input for adjusting the amount of light based on the visual object 913, the wearable device may transmit signals indicating the amount of light adjusted by the input to external electronic devices (e.g., the external electronic device 121 and the external electronic device corresponding to the visual object 152) selected by the user. The external electronic devices may operate based on the signals to have the amount of light adjusted by the user. In the state 910 of FIG. 9A, the wearable device may change the screen 911, based on identifying that the external electronic devices selected by the user are changed. For example, when the user additionally selects an external electronic device, the wearable device may cease displaying at least one of the visual objects 912, 913, 914, and 915 within the screen 911, based on functions applicable to the added external electronic device. For example, when the user excludes selection of a particular external electronic device, the wearable device may change the screen 911, based on functions commonly applicable to one or more external electronic devices finally selected by the user.

Referring to FIG. 9B, a state 920 in which the wearable device changes the screen 911 in response to (or based on) an input indicating additional selection of an external electronic device 123 in the state 910 of FIG. 9A is illustrated. In the state 920, in response to (or based on) the input indicating selection of the external electronic device 123, the wearable device may display a visual object 921, superimposed on the external electronic device 123 viewable through the FoV 110. Each of the visual objects 901, 902, and 921 may be displayed as associated with the external electronic devices selected by the user. The wearable device may display the screen 911 based on functions commonly applicable to the external electronic devices corresponding to the visual objects 901, 902, and 921. As the number of the external electronic devices selected by the user increases, the number of the functions commonly applicable to the external electronic devices may decrease. The wearable device may change the screen 911 based on a change of the functions commonly applicable to the external electronic devices.

In an example of FIG. 9B, when the external electronic device 123 additionally selected by the user does not support adjusting the color and the color temperature, the wearable device may cease displaying the visual objects 914 and 915 for adjusting the color and color temperature within the screen 911. The wearable device may maintain displaying other visual objects 912 and 913 different from the visual objects 914 and 915 within the screen 911, independently of ceasing the display of the visual objects 914 and 915. For example, the wearable device may display the visual object 913 for adjusting the amount of light, and the visual object 912 for control the power of external electronic devices corresponding to the visual objects 901, 902, and 921.

As described above, the wearable device according to an embodiment may display a visual object (e.g., the visual objects 913, 914, and 915) for execution of other functions commonly applicable to the external electronic devices, in addition to a function of collectively turning on or off external electronic devices selected by the user, such as the visual object 912.
