1A is a diagram for describing a method of operating a wearable device according to an exemplary embodiment. Referring to FIG. 1A , the wearable device 100 may detect a movement of an object to move a focus displayed on the item.

The object may be an object that can be detected in the vicinity of the wearable device 100 , a user's finger, or the like. “Nearby” of the wearable device 100 may mean an area within a preset distance from the wearable device 100 or an area within the same distance from the side of the wearable device 100 . For example, the periphery of the wearable device 100 may be the back of a user's hand wearing the wearable device 100 . Alternatively, the periphery of the wearable device 100 may be the front of the wearable device 100 . The periphery of the wearable device 100 may be an area in which the camera of the wearable device 100 may recognize an object.

Sensing the movement of the object may mean that the wearable device 100 detects a surrounding object and measures the direction, angle, movement distance, or speed in which the object moves.

The wearable device 100 includes a sensor 110 and a display unit 120 . The sensor 110 detects a surrounding object, and the display unit 120 displays at least one item and the focus 10 .

The item represents each function or menu of the wearable device 100 . The display 120 may display one item on the entire screen or display two or more items on the screen. Also, the display unit 120 may display different sizes of items. For example, the display 120 may display an item located in the center larger than other items.

The focus 10 is an identification mark indicating the currently selected item. The focus may be expressed in the form of changing the color of the item or changing the size of the item. Alternatively, the focus 10 may be a figure displayed on the item.

1A shows an example in which a focus 10 is displayed outside an item. 1 is a case in which six items (media controller, call, application, messenger, E-mail, Gallery) are displayed on the wearable device 100 . Also, FIG. 1 shows a process in which the focus 10 is displayed in Messenger and then displayed in Call.

The wearable device 100 detects the movement of an object through the sensor 110 . The sensor 110 detects whether the object is within a set distance. The sensor 110 measures the distance between the sensor 110 and the object. Alternatively, the sensor 110 may measure the movement direction, movement angle, and movement distance of the object.

1A illustrates a case in which the wearable device 100 recognizes a user's finger. The wearable device 100 may recognize the movement of various objects as well as the user's finger. For example, the wearable device 100 may recognize an object such as a pen or a stick.

The wearable device 100 displays a plurality of items on the display unit. Also, the wearable device 100 displays focus on at least one item among the plurality of items.

The wearable device 100 acquires the angle or direction in which the object moves. The wearable device 100 measures the position of the object, and when there is a change in the position of the object, calculates an angle or direction in which the object moves. In the case of FIG. 1A , a case in which the object moves in a 45 degree direction is illustrated. The wearable device 100 may set the range of the distance or speed, and may calculate the angle of the object only when the moving distance or speed of the object is included in the set range. Therefore, when the moving distance or speed of the object is not included in the set range (for example, when the moving distance is short or the speed is slow), it is determined that the fine movement of the object or the user does not want an input, and the wearable device ( 100 ) may not move the focus ( 10 ).

The wearable device 100 moves the focus to an item at a location corresponding to the direction in which the object moves. The wearable device 100 determines the moving direction of the focus 10 according to the moving direction of the object. The wearable device 100 moves the focus 10 shown on the display unit 120 to an item located in the determined moving direction. In the case of FIG. 1A , since the object has moved in a 45 degree direction, the wearable device 100 moves the focus 10 from Messenger to Call.

The wearable device 100 is a device that a user can wear on the body. For example, the wearable device 100 may be a smart watch, smart glasses, an arm band, or the like.

The wearable device 100 includes a sensor 110 . The sensor 110 may be disposed at a position where the wearable device 100 may detect a user's gesture. For example, in the case of a smart watch, the sensor 110 may be disposed on the side of the smart watch. In the case of smart glasses, the sensor 110 may be disposed in front of the smart glasses.

1B is a view for explaining a method of operating a wearable device having a sensor on its front side. Referring to FIG. 1B , the wearable device 100 includes sensors 110 on the front side. The front is an area in which the display unit 120 is provided. The two sensors 110 may be located above and below the display unit 120 .

The sensors 110 may detect an object moving in front of the wearable device 100 . For example, the sensors 110 may detect a user's finger moving from the front.

The wearable device 100 acquires the direction of the finger detected by the sensors 110 , and moves the focus to an item in a position corresponding to the obtained direction.

FIG. 2 is a diagram for describing a method of moving a focus displayed on a display of a wearable device using a movement of an object around the wearable device, according to an exemplary embodiment. In FIG. 2 , the wearable device 100 may measure an angle and determine a movement direction of a focus according to the measured angle.

In step 1 , the wearable device 100 measures an angle at which the object moves around it. In the case of FIG. 2, a case where the angle at which the object moves is 80 degrees is illustrated as an example. The angle of the object is calculated based on the wearable device 100 .

In step 2 , the wearable device 100 determines an area corresponding to the measured angle. The wearable device 100 presets regions according to angles and determines regions corresponding to the measured angles. For example, the wearable device 100 may set 360 degrees to at least two areas. In the case of FIG. 2 , the wearable device 100 is an example in which 360 degrees is set as four regions. An angle of 80 degrees is included in the second region. Accordingly, the wearable device 100 determines the second area as an area corresponding to the measured angle.

In step 3 , the wearable device 100 moves the focus displayed on the display unit in a direction corresponding to the determined area. In the case of Fig. 2, a case in which the focus is moved from Messenger to E-mail is shown.

3 is a flowchart illustrating a method of operating a wearable device according to an exemplary embodiment. Referring to FIG. 3 , the wearable device 100 may detect a surrounding object and move the focus from a first item to a second item.

In operation 310, the wearable device 100 displays focus on the first item on the screen. The wearable device 100 displays a focus on a first item among a plurality of items displayed on the screen.

In operation 320, the wearable device 100 detects a surrounding object. The wearable device 100 may detect a surrounding object using the sensor 110 .

In operation 330 , the wearable device 100 acquires a direction in which the surrounding object moves. The wearable device 100 may obtain a direction by calculating an angle at which an object moves based on the wearable device 100 .

In operation 340, the wearable device 100 determines a movement direction of the focus according to the obtained direction.

In operation 350 , the wearable device 100 moves the focus to the second item according to the determined moving direction.

The wearable device 100 may set regions corresponding to a direction in which the focus is movable, and may determine the direction of movement of the focus by mapping the regions and the obtained direction.

The focus-movable direction indicates a direction in which the focus-movable item is present according to an arrangement method of the items. The wearable device 100 may check a direction in which the focus can be moved, and may set as many areas as the number of the checked directions. In this case, the wearable device 100 sets regions each including movable directions. For example, if the movable direction is upward, the wearable device 100 may set -20 degrees to 20 degrees as the area corresponding to the upper part.

Mapping the regions and the acquired direction represents determining which region from among the regions the acquired direction is included. Regions are delimited by ranges of angles. For example, 0 degrees to 180 degrees may be set as the first area, and 180 degrees to 360 degrees may be set as the second area. The wearable device 100 determines a direction corresponding to the determined area. The wearable device 100 may determine an area including the obtained direction. Since the area is set to correspond to the direction in which the focus can be moved, the wearable device 100 may determine the direction of movement of the focus corresponding to the determined area.

4 is a diagram for explaining a method of changing a displayed item by determining an area according to an angle by a wearable device according to another exemplary embodiment. Referring to FIG. 4 , the wearable device 100 may change the displayed item according to the movement angle of the object.

In step 1 , the wearable device 100 measures the movement angle of the object. In the case of FIG. 2, a case where the movement angle of the object is 170 degrees is illustrated as an example.

In step 2 , the wearable device 100 determines an area corresponding to the measured movement angle. The wearable device 100 sets regions according to angles and determines regions including the measured angles. In the case of FIG. 2 , since the items are arranged in one column, only the upper item or the lower item of the current item may be displayed by a user's manipulation. Accordingly, the wearable device 100 divides 360 degrees in half, and sets the upper area as the first area and the lower area as the second area. An angle of 170 degrees measured in FIG. 2 corresponds to the second area. Accordingly, the wearable device 100 determines the second area as an area corresponding to the measured angle.

If the Gallery item is displayed, the upper area may be set as the neutral area, and the lower area may be set as the first area. When the movement angle of the object is included in the neutral region, the wearable device 100 does not change the displayed item. Since there is no longer an item to be displayed in the direction corresponding to the neutral region, the wearable device 100 may provide feedback to the user to inform that the Gallery item is the last item.

In step 3 , the wearable device 100 changes the displayed item. The wearable device 100 displays an item disposed in a direction corresponding to the determined area.

For example, the items may be arranged in one column, and since the angle included in the second area is obtained, the wearable device 100 displays E-mail, which is an item placed above the currently displayed Call, as an item to be displayed next. can decide

The wearable device 100 sets regions according to angles and determines regions including the measured angles. In the case of FIG. 6 , an angle of 80 degrees corresponds to the second area. Accordingly, the wearable device 100 determines the second area as an area corresponding to the measured angle.

In step 3 , the wearable device 100 moves the image in a direction corresponding to the determined area. In the case of FIG. 6 , since the direction corresponding to the second region is right, the image is moved to the right.

The wearable device 100 according to another embodiment may move the image in the same manner as the movement of the detected object. For example, when an object is detected, the wearable device 100 may calculate movement coordinates of the object based on the detected position of the object and move the image by the calculated movement coordinates. The wearable device 100 may move the center of the image by moving coordinates calculated from the center of the screen as a reference point.

As another example, the wearable device 100 may move an image by measuring an angle and a distance moved by a peripheral object of the wearable device 100 . In other words, the wearable device 100 moves the image at the measured angle, but moves the image by the measured distance or in proportion to the measured distance. When the wearable device 100 detects an object surrounding the wearable device 100 , the image may be moved using the detected position as a reference point.
