Abstract:
1. A gesture input device which generates a control signal for controlling a target device, based on a gesture of a user, the gesture input device comprising: a coordinate input detecting unit configured to sequentially detect sequences of sets of coordinates, the sets respectively corresponding to positions of a hand of the user; a gesture start detecting unit configured to detect a component indicating a first hand movement predetermined as a hand movement which is made when the user intends to start a gesture, from a first coordinate sequence included in the sequences of sets of coordinates detected by the coordinate input detecting unit; a guide image generating unit configured to generate a gesture guide image for guiding the user to make a gesture after a second hand movement, when the component indicating the first hand movement is detected by the gesture start detecting unit, the second hand movement being started at a first position included in the positions corresponding to the sets of coordinates detected by the coordinate input detecting unit, the gesture guide image being displayed at a second position, the second position being a position of a cursor after the second hand movement; a display screen control unit configured to sequentially display the cursor at the positions on the display screen corresponding to the sets of coordinates detected by the coordinate input detecting unit, and display the gesture guide image generated by the guide image generating unit on the display screen; an intended action component detecting unit configured to detect a component indicating the second hand movement as an intended action component of the gesture, from a second coordinate sequence which is included in the sequences of sets of coordinates detected by the coordinate input detecting unit, after the gesture guide image is displayed on the display screen by the display screen control unit; and a control signal generating unit configured to detect a component indicating a hand movement corresponding to the gesture and succeeding the intended action component from the second coordinate sequence when the intended action component is detected by the intended action component detecting unit, and generate a control signal in accordance with a result of the detection, wherein the second position is different from a position of the cursor at the time when the component indicating the first hand movement is detected, the second hand movement is a hand movement for moving the cursor from (i) the position of the cursor at the time when the component indicating the first hand movement is detected to (ii) the second position, and the second position is displayed to be apart from the position of the cursor at the time when the component indicating the first hand movement is detected in a direction different from a movement direction of the cursor at the time when the component indicating the first hand movement is detected.
