FIG. 1A illustrates a method of operation of a wearable device 100 in accordance with an embodiment. Referring to FIG. 1A, the wearable device 100 senses object movement to shift the focus 10 from one item to another.

The item may be an item sensed in the periphery of the wearable device 100 (such as a user's finger). The "periphery" of the wearable device 100 refers to an area within a predetermined distance from the side surface of the wearable device 100 or the self-wearing device 100. For example, the perimeter of the wearable device 100 can be the back or front of the user's hand that wears the wearable device 100. The perimeter of the wearable device 100 can be an area of an item that can be recognized via a camera of the wearable device 100.

The movement of the sensing object is used to indicate that the wearable device 100 senses peripheral objects and measures parameters such as the direction of movement, the angle of movement, the distance of movement, and the speed of movement of the article.

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

At least one item indicates a menu function of the wearable device 100. The display unit 120 displays one item on the entire screen or two or more items on the screen. The display unit 120 can display different item sizes. For example, display unit 120 displays the centered item as being larger than the other items.

Focus 10 is an identification display indicating the currently selected item. The focus 10 can be represented in some way such that the color of the item or its size is changed. Alternatively, focus 10 can be a graphic that is displayed on the item.

FIG. 1A illustrates an example of a focus 10 outside of at least one item. In Figure 1A, six items ('Media Controller', 'Call', 'Application', 'Messager', E-mail, and 'Gallery' ) is displayed on the wearable device 100. Figure 1A illustrates the procedure for displaying focus 10 on a &apos;Messager&apos; and then adjusting focus 10 to a &apos;call&apos; item.

The sensor 110 of the wearable device 100 detects the movement of the object and whether the object is within a set distance. The sensor 110 measures the moving direction, the moving angle, and the moving distance of the object.

In FIG. 1A, the wearable device 100 recognizes the movement of the user's fingers and various items. For example, the wearable device 100 recognizes an item such as a pen.

The wearable device 100 displays a plurality of items on the display unit 120. The wearable device 100 displays the focus 10 on at least one of the plurality of items.

The wearable device 100 obtains the moving angle or moving direction of the object. When the wearable device 100 measures the position of the object and when the position of the object changes, the wearable device 100 calculates the moving angle or moving direction of the object. In Figure 1A, the object moves in a 45 degree direction. The wearable device 100 sets the distance or speed range, and calculates the moving angle of the object only when the moving distance or moving speed of the object is within the set range. Therefore, when the moving distance or moving speed of the object is not within the set range (for example, the moving distance is short or the moving speed is slow), the wearable device 100 determines that the object has a small movement or the user does not want to make an input. In this case, the wearable device 100 does not move Bit focus 10.

The wearable device 100 shifts the focus 10 to an item at a position corresponding to the moving direction of the object, and determines the moving direction of the focus 10 according to the moving direction of the object. The wearable device 100 shifts the focus 10 displayed on the display unit 120 to an item positioned in the determined moving direction. In Figure 1A, the item moves in a 45 degree direction, and thus the wearable device 100 shifts the focus 10 from the 'Signal' item to the 'Call' item.

The wearable device 100 can be worn by a user on his or her body (such as a smart watch, smart glasses, or an armband).

The wearable device 100 includes two sensors 110 disposed in a position in which the wearable device 100 can sense a user's gesture, such as in a side surface of a smart watch, as illustrated in FIG. 1A. In another example, the sensor 110 is disposed in front of the smart glasses.

FIG. 1B illustrates a method of operation of a wearable device 100 that includes a sensor 110 in front of the wearable device. Referring to FIG. 1B, the wearable device 100 includes a sensor 110 and a display unit 120 including a front area. The two sensors 110 are positioned on the upper side and the lower side of the display unit 120.

The sensors 110 are used to detect objects moving in front of the wearable device 100, for example, by sensing a user's finger moving in front of the sensor 110, as illustrated in FIG. 1B.

The wearable device 100 obtains the direction of the user's finger sensed by the sensor 110 and shifts the focus 10 to an item at a position corresponding to the obtained direction.

2 illustrates by being in the periphery of the wearable device 100, according to an embodiment The method of moving the object to adjust the focus 10 displayed on the display unit of the wearable device 100. Referring to FIG. 2, the wearable device 100 measures the angle and determines the direction of movement of the focus 10 based on the measured angle.

In operation 1, the wearable device 100 measures the angle of movement of the article in the periphery of the wearable device 100. In FIG. 2, for example, the movement angle of the article is 80 degrees and is calculated relative to the wearable device 100.

In operation 2, the wearable device 100 determines an area corresponding to the measured angle. The wearable device 100 can previously set an area based on the measured angle and determine an area corresponding to the measured angle. For example, the wearable device 100 can set 360 degrees to include at least two regions. In FIG. 2, the wearable device 100 sets 360 degrees to include four regions. An angle of 80 degrees can be in the second zone. Therefore, the wearable device 100 determines the second region to correspond to the measured angle.

In operation 3, the wearable device 100 shifts the focus 10 displayed on the display unit in a direction corresponding to the determined region. In Figure 2, focus 10 is shifted from the 'Signal' item to the 'Email' item.

FIG. 3 is a flow chart of a method of operation of the wearable device 100 in accordance with an embodiment. Referring to Figure 3, the wearable device 100 detects surrounding objects and shifts the focus from the first item to the second item.

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

In operation 320, the wearable device 100 detects surrounding objects by using the sensor 110.

In operation 330, the wearable device 100 is relative to the wearable device 100 calculates the moving angle of the peripheral object to obtain the moving direction of the surrounding object.

In operation 340, the wearable device 100 determines the direction of displacement of the focus based on the obtained direction.

In operation 350, the wearable device 100 shifts the focus to the second item in accordance with the determined direction of movement.

The wearable device 100 sets an area corresponding to the shiftable direction of the focus, draws the area and the obtained direction, and determines the shift direction of the focus.

The shiftable direction of the focus is the direction in which the item on which the focus can be shifted is currently rendered by using the project configuration method. The wearable device 100 determines the shiftable direction of the focus and sets the area to the number of checked directions. In this regard, the wearable device 100 sets the area (including the movable direction). For example, if the movable direction is toward the upper side, the wearable device 100 sets an angle from about -20 degrees to about 20 degrees as an area corresponding to the upper side.

The drawing area and the obtained direction relate to which of the decision areas (which can be identified as the range of angles) contains the obtained direction. For example, an angle from about 0 degrees to about 180 degrees can be set as the first area and an angle from about 180 degrees to about 360 degrees can be set as the second area. The wearable device 100 determines the direction corresponding to the determined region. The wearable device 100 determines the area containing the obtained direction. The area may be set to a movable direction corresponding to the focus and thus the wearable device 100 determines the moving direction of the focus corresponding to the determined area.

4 illustrates a method of changing a displayed item by a wearable device 100 by determining an area according to an angle, in accordance with another embodiment. Referring to FIG. 4, the wearable device 100 changes the displayed item according to the moving angle of the object.

In operation 1, the wearable device 100 measures the moving angle of the object, In Figure 4, it is 170 degrees.

In operation 2, the wearable device 100 determines an area corresponding to the measured movement angle. The wearable device 100 sets an area based on the measured movement angle and determines an area including the measured movement angle. In FIG. 4, the items are arranged in a row, and thus the upper or lower items of the current item can be displayed according to user manipulation. Therefore, the wearable device 100 divides 360 degrees into two halves, sets the upper region as the first region, and sets the lower region as the second region. In FIG. 4, the measured angle of 170 degrees corresponds to the second area. Therefore, the wearable device 100 determines the second region to correspond to the measured movement angle.

In Fig. 4, if the display item is "Gallery", the upper area can be set to a neutral region and the lower area can be set as the first area. When the moving angle of the object is included in the neutral region, the wearable device 100 may not change the displayed item. The item to be displayed no longer exists in the direction corresponding to the neutral area, and thus the wearable device 100 provides feedback to the user to inform the user that the item 'gallery' is the last item.

In operation 3, the wearable device 100 changes the display item. The wearable device 100 displays items placed in a direction corresponding to the determined area.

For example, the items are configured in one row and the angles included in the second region are obtained. Therefore, the wearable device 100 determines the item 'email' placed in the upper position of the currently displayed item 'Call' as the item to be displayed next.

FIG. 5 is a flow chart of a method of operation of the wearable device 100 in accordance with another embodiment. Referring to FIG. 5, the wearable device 100 detects surrounding objects to change the displayed items according to the moving direction of the surrounding objects.

In operation 550, the wearable device 100 displays the determined second item on the display unit of the wearable device 100.

The wearable device 100 sets a corresponding region according to the item configuration and determines the displayed item by determining an area including the obtained direction.

6 illustrates a method in which wearable device 100 determines an area corresponding to an angle and moves an image, in accordance with an embodiment of the illustrative embodiments.

In operation 2, the wearable device 100 determines an area corresponding to the measured angle. The wearable device 100 sets an area according to an angle and determines an area including the measured angle. In Fig. 6, 80 degrees corresponds to the second area. Therefore, the wearable device 100 determines the second region to correspond to the measured angle.

In operation 3, the wearable device 100 moves the image in a direction corresponding to the determined region. In Figure 6, the right direction corresponds to the second area and thus the image moves to the right.

According to another embodiment, the wearable device 100 is the same as the detected object Move the image in a moving way. For example, if an object is detected, the position of the wearable device 100 relative to the detected object calculates the moving coordinate of the object and moves the image to calculate the moving coordinate. The wearable device 100 moves the image center to the calculated moving coordinates by using the screen center as a reference point.

According to another embodiment, the wearable device 100 measures the angle of movement and the distance of the peripheral items of the wearable device 100 to move the image. In other words, the wearable device 100 moves the image by the measured angle at a measured angle or is proportional to the measured distance. If the surrounding object of the wearable device 100 is detected, the wearable device 100 moves the image by using the detected position as a reference point.

The memory 130 stores material for operating the wearable device 100. For example, the memory 130 stores programs, images, and materials for performing arithmetic operations.

The processor 140 controls the operation of the wearable device 100. The processor 140 determines an image displayed on the display unit 120 by using data received from the sensor 110. For example, the processor 140 receives information about the movement of the object from the sensor 110 and shifts the focus displayed on the display unit 120. The processor 140 changes the items displayed on the display unit 120 and moves the images.

The processor 140 obtains the moving direction of the peripheral object based on the information received from the sensor 110. The processor 140 calculates the coordinates of the coordinates of the starting point at which the peripheral object starts moving and the coordinates of the ending point at which the peripheral object stops moving, and obtains the moving direction of the peripheral object by using the wearable device 100 and the positional relationship between the starting point and the ending point. .

The processor 140 determines the shift direction of the focus based on the obtained direction. The processor 140 sets an area according to the obtained direction and determines a shift direction of the focus. processor 140 sets a plurality of areas in accordance with the screen display state of the wearable device 100. The processor 140 can adaptively set an area corresponding to the shiftable direction of the focus. The processor 140 sets the area differently depending on the screen display state. The processor 140 determines which of the regions contains the obtained direction. The processor 140 determines the direction of movement corresponding to the determined region.

FIG. 9 is a block diagram of a wearable device 100 in accordance with another embodiment. Referring to FIG. 9, the processor 140 of the wearable device 100 includes a direction obtaining unit 141, a moving direction determining unit 142, and a control unit 143.

The direction obtaining unit 141 obtains the moving direction of the object based on the information received from the sensor 110. For example, the direction obtaining unit 141 measures the distance between the object and the first and second sensors of the wearable device 100. The direction obtaining unit 141 obtains the moving direction of the object by using the distance between the first sensor and the object, the distance between the second sensor and the object, and the distance between the first and second sensors. Alternatively, the direction obtaining unit 141 calculates the object by using the distance between the first sensor and the object, the distance between the second sensor and the object, and the distance between the first and second sensors. coordinate. When the coordinates are calculated, the center of the wearable device 100 can be the original point.

And the coordinates of the end point at which the object stops moving, and the moving direction of the object is obtained by using the wearable device 100 and the positional relationship between the start point and the end point.

The moving direction decision unit 142 determines the shift direction of the focus in accordance with the obtained direction. The moving direction determining unit 142 sets the area according to the direction and determines the shifting direction of the focus.

The moving direction determining unit 142 sets a plurality of areas in accordance with the screen display state of the wearable device 100. The moving direction decision unit 142 adaptively sets an area corresponding to the shiftable direction of the focus. The moving direction determining unit 142 sets the area differently depending on the screen display state.

The control unit 143 shifts the focus to the second item in accordance with the determined moving direction. The moving direction decision unit 142 sets a neutral region corresponding to the direction in which the focus is not shifted. When the moving direction of the object is included in the neutral area, the control unit 143 does not shift the focus and provides appropriate feedback to the user.

When the moving direction of the object is included in the neutral region, the moving direction decision unit 142 determines the shifting direction of the focus based on the history regarding the previously stored moving direction of the object. In other words, the moving direction decision unit 142 causes the neutral region to be included in another region by the learning program.

For example, when the moving direction of the object corresponds to the neutral region, and the next moving direction of the object corresponds to the first region adjacent to the neutral region, the moving direction determining unit 142 includes the neutral region in the first region. In the area. Therefore, if the subsequent measurement moving direction of the object is included in the neutral region, the moving direction determining unit 142 determines the moving direction of the object to correspond to the first region.

The learning program described above is merely an example. That is, the moving direction decision unit 142 instead uses various rules to execute the learning program and when the object moves When included in the neutral zone, the direction of movement of the object is determined differently by the learning program.

When the moving direction of the object is included in the neutral area, the control unit 143 provides feedback to the user. For example, the control unit 143 drives the vibration device or partially modifies the image displayed on the display unit 120.

The control unit 143 changes the displayed item according to the determined moving direction and inputs a character.

When the gesture of the object is sensed, the control unit 143 performs an operation corresponding to the gesture. For example, when the direction obtaining unit 141 obtains at least two moving directions of the object within a predetermined time, the control unit 143 performs an operation corresponding to at least two moving patterns of the object.

The direction obtaining unit 141, the moving direction determining unit 142, and the control unit 143 may be software modules implemented in the processor 140.
