4A and 4B are views for explaining an embodiment of a motion recognition method using a motion interface device according to an embodiment of the present invention.

4A, when the user grasps the motion interface device 100 or moves the finger or wrist or arm to the left side with the motion interface device 100 attached to the finger or wrist or arm, The volume of the user terminal 200 can be increased or decreased by rotating the finger, the wrist, or the arm.

That is, when the user moves the finger, the wrist or the arm to the left side (1), the controller 140 determines that the operation is the volume control operation. When a user rolls a finger, a wrist or an arm in a forward direction on the basis of a left movement vector, a control signal for raising the volume corresponding to the number of rotation or the rotation speed is generated, A control signal for lowering the volume corresponding to the number of rotations or the rotation speed is generated and transmitted to the user terminal 200. [

On the other hand, in the state where the user grasps the motion interface device 100 or moves the finger or wrist or arm to the right in a state in which the motion interface device 100 is attached to the finger or wrist or arm, When the wrist or arm is rotated, the channel of the user terminal 200 can be raised or lowered.

That is, when the user moves the finger, the wrist or the arm to the right side (4), the controller 140 determines that the control operation is for the volume. If the user makes a roll (⑤) of a finger, a wrist or an arm on the basis of a right movement vector, a control signal for changing from a current channel to a higher channel corresponding to the number of rotations or rotation speed is generated, If the user rotates the finger or wrist or arm in the backward direction based on the right movement vector, the controller generates a control signal changing from the current channel to the lower channel corresponding to the number of rotations or the rotation speed, (200).

In FIG. 4A, the user moves the finger or wrist or arm to the left or right and rotates. However, even if the user does not move the cursor to the left or right, The control unit 140 can determine that the control unit 140 is in the standby mode.

4B, when the user grasps the motion interface device 100 or moves the finger or wrist or arm upward in a state where the motion interface device 100 is attached to the finger or the wrist or the arm, The volume of the user terminal 200 can be increased or decreased by rotating the finger, the wrist, or the arm around the vector.

That is, when the user moves the finger, the wrist or the arm upward (7), the controller 140 judges that the operation is the volume control operation. Then, when the user rotates the finger, wrist or arm clockwise (8) on the basis of the upward movement vector, a control signal for increasing the volume corresponding to the number of rotation or the rotation speed is generated, A control signal for lowering the volume in accordance with the number of rotations or the rotation speed is generated and transmitted to the user terminal 200. In this case,

Similarly, in the state where the user grasps the motion interface device 100 or moves the finger or wrist or arm downward with the motion interface device 100 attached to the finger or wrist or arm, When the wrist or arm is rotated, the channel of the user terminal 200 can be raised or lowered.

That is, when the user moves the finger, the wrist or the arm to the lower side (10), the controller 140 judges that it is the control operation for the volume. When the user rotates a finger, a wrist or an arm in a clockwise direction (11) on the basis of a lower movement vector, a control signal for changing from a current channel to a higher channel corresponding to the number of rotations or rotation speed is generated, When the user rotates the finger, wrist or arm counterclockwise (12) on the basis of the lower movement vector, a control signal for changing from the current channel to the lower channel in response to the number of rotations or rotation speed is generated, To be transmitted to the terminal 200.

On the other hand, FIG. 4B shows that the user moves the finger or wrist or arm to move upward or downward. However, even if the user moves the finger or wrist or the arm to the upper side or the lower side with respect to the horizontal line, The control unit 140 can determine that the user is in the standby mode.

5A and 5B are views for explaining another embodiment of a motion recognition method using a motion interface device according to an embodiment of the present invention.

First, FIG. 5A is a modification of FIG. 4A. In the state where the user attaches the motion interface device 100 to a finger or a wrist or an arm, the finger or the wrist or arm is moved to the left, The volume of the user terminal 200 can be increased or decreased by rotating the finger, the wrist, or the arm around the vector.

That is, when the user moves the finger, the wrist or the arm to the left side and returns to the original position (a), the controller 140 determines that the control operation is for the volume. When the user rotates the finger, wrist or arm in the forward direction on the basis of the left movement vector, the controller generates a control signal for increasing the volume corresponding to the number of rotation or the rotation speed, A control signal for lowering the volume in accordance with the number of rotations or the rotation speed is generated and transmitted to the user terminal 200. [

On the other hand, in a state where the user holds the motion interface device 100 or moves the finger or the wrist or arm to the right and returns to the original position with the motion interface device 100 attached to the finger or wrist or arm Rotating the finger, wrist or arm around the motion vector may raise or lower the channel of the user terminal 200.

That is, when the user moves the finger, the wrist or the arm to the right side and returns to the original position (D), the controller 140 determines that the control operation is for the volume. When the user rotates the finger, wrist or arm in the forward direction on the basis of the right movement vector, the controller generates a control signal changing from the current channel to the high channel corresponding to the number of rotations or the rotation speed, When a user rolls a finger, a wrist or an arm in the backward direction on the basis of the right movement vector, a control signal for changing from a current channel to a lower channel corresponding to the number of rotations or the rotation speed is generated, (200).

5B, when the user holds the motion interface device 100 or attaches the motion interface device 100 to the finger or wrist or arm, the finger or wrist or arm is moved upward, The volume of the user terminal 200 can be increased or decreased by rotating the finger, the wrist, or the arm around the movement vector.

That is, when the user moves the finger, wrist or arm upward and then returns to the original position, the controller 140 determines that the control operation is for the volume. When the user rotates the finger, the wrist or the arm in the clockwise direction on the basis of the upper movement vector, a control signal for increasing the volume in accordance with the number of rotation or the rotation speed is generated, A control signal for lowering the volume in accordance with the number of rotations or the rotation speed is generated and transmitted to the user terminal 200. [

Likewise, in a state where the user holds the motion interface device 100 or moves the finger or wrist or arm downward and returns to the original position with the motion interface device 100 attached to the finger or wrist or arm Rotating the finger, wrist or arm around the motion vector may raise or lower the channel of the user terminal 200.

That is, when the user moves the finger, the wrist or the arm downward and returns to the original position, the controller 140 determines that the control operation is for the volume. When a user rotates a finger, a wrist or an arm in a clockwise direction on the basis of a lower movement vector, a control signal changing from a current channel to a higher channel is generated corresponding to the number of rotations or the rotation speed, When a user rotates a finger, a wrist or an arm counterclockwise on the basis of a lower movement vector, a control signal for changing from a current channel to a lower channel corresponding to the number of rotations or rotation speed is generated, To be transmitted to the terminal 200.

4A and FIG. 5B, when the user moves the finger or wrist or arm to the left or the upper side, the volume is adjusted, and when the user moves the finger or wrist or arm to the right or lower side, the channel is changed. However, It is possible to design by changing the control signal for the volume or channel according to the moving direction of the arm.

4A to 5B, when the user rotates the finger or the wrist or arm forward or backward and then returns to the original position, the volume or channel can be changed, and conversely, The user can change the channel or the volume by rotating the finger or wrist or arm backward, or moving the finger or wrist or arm backward and returning to the original position.

Likewise, the direction of rotation of the finger or wrist or the arm, which can control the increase or decrease of the volume or the channel, can also be changed according to the user's convenience.

4A and FIG. 5B, the channel or the volume is controlled according to the movement of the user. However, in addition to the channel or volume control, the user can scroll, zoom in / zoom out, turn pages, Lt; / RTI >

Accordingly, the control unit 140 may be configured to rotate the finger, the wrist, or the arm based on a direction vector corresponding to a predetermined direction after the user moves the finger or wrist or arm in a predetermined direction, The user can move the scroll upward or downward, zoom in or zoom out, or move the scroll to the previous page or the next page in accordance with the rotation direction Move, activate the previous active program or the next active program, or execute the previous music file or the next music file.

The process of the controller 140 generating various control signals is the same as that of FIGS. 4A to 5B, and thus a duplicated description will be omitted.

6A and 6B are views for explaining another embodiment of a motion recognition method using a motion interface device according to an embodiment of the present invention.

6A and 6B illustrate a process of changing or selecting a channel through the motion interface device 100 by a user.

6A shows a state in which a channel list is displayed in a vertical direction on a screen of the user terminal 200, and FIG. 6B shows a state in which a channel list is displayed in a horizontal direction on a screen of the user terminal 200. [

6A and 6B, when the user attaches the motion interface device 100 to the user's finger or wrist or arm, the user can move the motion interface device 100 in the forward direction or the clockwise direction with respect to one direction vector in the X, Y, The control unit 140 controls the channel list to change a channel higher than the current channel to a selectable channel (a hatched display channel).

Further, when the user grasps the motion interface device 100 or rotates in the backward direction or the counterclockwise direction based on one of the X, Y, and Z axes in a state where the user holds the motion interface device 100 or attaches the motion interface device 100 to the user's finger, wrist or arm , The controller 140 controls the channel list to change a channel lower than the current channel to a selectable channel (a hatched display channel). The user can select a channel by touching a button or the like with respect to the channel located in the selectable channel.

Here, the rotation direction of the motion interface device 100 for changing the reference vector and the channel list from among the X, Y, and Z axes may be changed according to the use or environment of the motion interface device 100.

6A and 6B, the channel list is selected. However, the present invention can also be applied to the character selection of various games, the volume control, and the selection of various menus.
