Wearable device
A wearable device includes a detection module configured to be worn by an upper limb of a user and detect a body motion in the upper limb, and a controller configured to detect the body motion in the upper limb on a basis of a detection result from the detection module and generate a control signal in accordance with the body motion. If the controller detects, as the body motion, at least two of a finger motion, a hand motion, and an arm motion in the upper limb within a first predetermined period of time, the controller recognizes the two body motions as a series of body motions and generates, as the control signal, a first control signal in accordance with the series of body motions.
1. A wearable device, comprising:
a detection module configured to be worn by an upper limb of a user and detect a body motion in the upper limb; and
a controller configured to detect the body motion in the upper limb on a basis of a detection result from the detection module and generate a control signal in accordance with the body motion, wherein
when the controller detects, as the body motion, at least two of a finger motion, a hand motion, and an arm motion in the upper limb within a first predetermined period of time, the controller
recognizes the two body motions as a series of body motions,
generates, as the control signal, a first control signal in accordance with the series of body motions, and
manipulates a first display object from a plurality of display objects displayed in a display area,
when the controller detects only one of the at least two body motions within the first predetermined period of time, the controller
generates a second control signal in accordance with the one of the at least two body motions, and
manipulates a second display object from the plurality of display objects,
the first display object is displayed, in an object selectable area, farther away from the user than the second display object in a depth direction of the display area, and
the two body motions for manipulating the first display object, which is farther away from the user than the second display object in the depth direction, include a backward motion of pulling the upper limb of the user backwards toward the user's body, wherein the backward motion is a first motion in the two body motions.
2. The wearable device according to claim 1 , comprising a communication module configured to transmit the control signal to an external display device, wherein
the controller is configured to generate, as the control signal, a display control signal for controlling display contents of the external display device.
3. The wearable device according to claim 2 , wherein when the controller recognizes the series of body motions, the controller measures a period of time during which the series of body motions is performed and generates the display control signal in accordance with the period of time.
4. The wearable device according to claim 2 , wherein when the controller recognizes the series of body motions, the controller detects a displacement amount in accordance with the series of body motions in a predetermined part of the upper limb and generates the display control signal in accordance with the displacement amount.
5. The wearable device according to claim 2 , wherein when the controller recognizes the series of body motions, the controller detects a directional change amount in accordance with the series of body motions in a predetermined part of the upper limb and generates the display control signal in accordance with the change amount.
6. The wearable device according to claim 1 , comprising a display module, wherein
the controller is configured to generate, as the control signal, a display control signal for controlling display contents of the display module.
7. The wearable device according to claim 6 , wherein when the controller recognizes the series of body motions, the controller measures a period of time during which the series of body motions is performed and generates the display control signal in accordance with the period of time.
8. The wearable device according to claim 6 , wherein when the controller recognizes the series of body motions, the controller detects a displacement amount in accordance with the series of body motions in a predetermined part of the upper limb and generates the display control signal in accordance with the displacement amount.
9. The wearable device according to claim 6 , wherein when the controller recognizes the series of body motions, the controller detects a directional change amount in accordance with the series of body motions in a predetermined part of the upper limb and generates the display control signal in accordance with the change amount.
10. The wearable device according to claim 1 , wherein
another one of the at least two body motions is either the finger motion or the hand motion, and
the backward motion of pulling the upper limb of the user backwards is the arm motion of pulling the hand of the user backwards toward the user's body.
11. The wearable device according to claim 1 , wherein
the controller is configured to
set the object selectable area for selecting one of the plurality of display objects, and
manipulate the first display object or the second display object by the control signal generated in accordance with the body motion, when the first or second display object partially or fully overlaps the object selectable area.
12. The wearable device according to claim 11 , wherein
the controller is configured to set the object selectable area as a circular region,
the circular region having a center at an end of an object corresponding to the user's finger, and
the circular region having an area larger than an area of the end of the object corresponding to user's finger.
13. The wearable device according to claim 1 , wherein the second display object is displayed as covering a part of the first display object.
