Wearable device

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.
