  FIG. 1A is a diagram illustrating an operation method of a wearable device according to an embodiment. Referring to FIG. 1A, the wearable device 100 can sense the movement of an object and move the focus displayed on the item.

  The object may also be an object sensed around the wearable device 100 (periphery), a user's finger, or the like. The “periphery” of the wearable device 100 means 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 is also the back of the user's hand wearing the wearable device 100. Alternatively, the periphery of the wearable device 100 is also the front surface of the wearable device 100. The periphery of the wearable device 100 is also an area where the camera of the wearable device 100 can recognize an object.

  Sensing the movement of the object means that the wearable device 100 senses a peripheral object and measures a direction, an angle, a moving distance, or a speed of the moving object.

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

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

  The focus 10 is an identification display indicating the currently selected item. The focus 10 is also expressed by a form that changes the hue of the item or changes the size of the item. Alternatively, the focus 10 is also a graphic displayed on the item.

  In the case of FIG. 1A, the case where the focus 10 is displayed on the outline of the item is shown. FIG. 1A shows a case where six items (Media controller, Call, Application, Messenger, E-mail, Gallery) are displayed on the wearable device 100. FIG. 1A shows a process in which the focus 10 is displayed on the Messenger and displayed on the Call.

  The wearable device 100 detects the movement of the object through the sensor 110. The sensor 110 detects whether or not an object is within a set distance. The sensor 110 measures the distance between the sensor 110 and the object. Alternatively, the sensor 110 can measure the moving direction, moving angle, and moving distance of the object.

  In the case of FIG. 1A, the case where the wearable device 100 recognizes a user's finger is illustrated. The wearable device 100 can recognize not only a user's finger but also various object movements. For example, the wearable device 100 can also recognize things such as pens and sticks.

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

  The wearable device 100 acquires the angle or direction in which the object has moved. The wearable device 100 measures the position of the object, and calculates the angle or direction in which the object moves when the position of the object varies. In the case of FIG. 1A, a case where the object moves in the 45 ° direction is illustrated. The wearable device 100 may set a range of distance or speed, and may calculate the angle of the object only when the moving distance of the object or the 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), as a fine movement of the object or when the user does not wish to input The wearable device 100 does not move the focus 10.

  Wearable device 100 moves the focus to an item at a position corresponding to the direction in which the object has moved. The wearable device 100 determines the moving direction of the focus 10 along the direction in which the object has moved. The wearable device 100 moves the focus 10 illustrated on the display unit 120 to an item positioned in the determined movement direction. In the case of FIG. 1A, since the object has moved in the 45 ° direction, the wearable device 100 moves the focus 10 from Messenger to Call.

  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, a smart glass, an armund, or the like.

  Wearable device 100 includes a sensor 110. The sensor 110 is disposed at a position where the wearable device 100 can sense a user's gesture. For example, in the case of a smart watch, the sensor 110 is disposed on the side surface of the smart watch. In the case of smart glass, the sensor 110 is disposed in front of the smart glass.

  FIG. 1B is a diagram for explaining an operation method of a wearable device including a sensor on the front surface. Referring to FIG. 1B, the wearable device 100 includes a sensor 110 on the front surface. The front is an area where the display unit 120 is provided. The two sensors 110 may be located above and below the display unit 120.

The sensor 110 can sense an object moving in front of the wearable device 100. For example, the sensor 110 can sense a user's finger moving in front.
The wearable device 100 acquires the direction of the finger sensed by the sensor 110 and moves the focus to an item at a position corresponding to the acquired direction.

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

  In Step 1, the wearable device 100 measures the angle at which the object moves around. In the case of FIG. 2, an example in which the angle of movement of the object is 80 ° is illustrated. The angle of the object is calculated based on the wearable device 100.

  In Step 2, the wearable device 100 determines a region corresponding to the measured angle. The wearable device 100 presets a region according to an angle, and determines a region corresponding to the measured angle. For example, wearable device 100 can set 360 ° to at least two regions. In the case of FIG. 2, the wearable device 100 is an example in which 360 ° is set to four regions. The angle of 80 ° is included in the second region. Therefore, the wearable device 100 determines the second region as a region corresponding to the measured angle.

  In Step 3, 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 where the focus moves from Messenger to E-mail is illustrated.

In step 330, the wearable device 100 acquires a direction in which the peripheral object moves. The wearable device 100 can acquire the direction by calculating the angle at which the object moves based on the wearable device 100.
In operation 340, the wearable device 100 determines a moving direction of the focus along the acquired direction.
In step 350, the wearable device 100 moves the focus to the second item along the determined movement direction.

  The wearable device 100 can set an area corresponding to the direction in which the focus can move, and can map the area and the acquired direction to determine the moving direction of the focus.

  The direction in which the focus can be moved indicates the direction in which the item to which the focus can currently move is present according to the item arrangement method. The wearable device 100 can confirm the direction in which the focus can move, and can set as many regions as the number of confirmed directions. At this time, the wearable device 100 sets areas each including a movable direction. For example, if the movable direction is the upper side, the wearable device 100 can set −20 ° to 20 ° as a region corresponding to the upper side.

  Mapping the region and the acquired direction indicates that it is determined in which region the acquired direction is included in the region. The region is divided by a range of angles. For example, 0 ° to 180 ° is set in the first region, and 180 ° to 360 ° is set in the second region. Wearable device 100 determines a direction corresponding to the determined area. The wearable device 100 can determine an area including the acquired direction. Since the area is set in correspondence with the direction in which the focus can move, the wearable device 100 can determine the movement direction of the focus corresponding to the determined area.

FIG. 4 is a diagram for explaining a method in which a wearable device according to another embodiment determines an angle area and changes displayed items. Referring to FIG. 4, the wearable device 100 can change an item displayed according to the moving angle of the object.

  In Step 2, the wearable device 100 determines an area corresponding to the measured movement angle. The wearable device 100 sets an area according to an angle, and determines an area including the measured angle. 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 is displayed by the user's operation. Therefore, wearable device 100 divides 360 ° in half, sets the upper area as the first area, and sets the lower area as the second area. The angle 170 ° measured in FIG. 2 corresponds to the second region. Therefore, the wearable device 100 determines the second region as a region corresponding to the measured angle.

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

  In Step 3, the wearable device 100 changes the displayed item. Wearable device 100 displays items arranged in a direction corresponding to the determined area.

  For example, since the items are arranged in one row and the angle included in the second area is acquired, the wearable device 100 follows the E-mail that is the item arranged above the currently displayed Call. It can be determined that the item is displayed on

The wearable device 100 sets an area according to an angle, and determines an area including the measured angle. In the case of FIG. 6, the angle of 80 ° corresponds to the second region. Therefore, the wearable device 100 determines the second region as a region 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 the right side, the case where the image has moved to the right side is illustrated.

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

  In yet another example, the wearable device 100 may measure an angle and a distance that a peripheral object of the wearable device 100 has moved, and move an image. In other words, the wearable device 100 moves the image by the measured angle, but moves the image by the measured distance or in proportion to the measured distance. When the wearable device 100 detects the peripheral object of the wearable device 100, the wearable device 100 can move the image with the detected position as a reference point.
