Abstract

An input apparatus including an input unit to which a predetermined motion image signal is input, a motion detection unit for detecting a motion from the motion image signal which is input to the input unit, a video signal processing unit for outputting a predetermined video signal, and a control unit, wherein if a hand revolving motion of an operator is detected, the control unit controls the video signal processing unit to output a predetermined first video signal in synchronism with the hand revolving motion in order to inform the operator of a detection situation of the revolving motion and to output a predetermined second video signal in synchronism with the first video signal in order to inform the operator of a progress situation of a manipulation until a predetermined manipulation is definitely fixed.

Claims

1. An input apparatus comprising:

an input unit to which a motion of an operator is input as an image signal;

an action detection unit for detecting a hand motion from the image signal which is input to the input unit;

a display unit for displaying a graphical user interface; and

a control unit for changing the graphical user interface displayed on the display unit in accordance with the hand motion detected by the action detection unit,

wherein the control unit moves a pointer so as to be in synchronism with the hand motion detected by the action detection unit and changes the graphical user interface so as to indicate an action quantity which corresponds to a quantity of the pointer movement.

2. The input apparatus according to claim 1, wherein

the hand motion detected by the action detection unit is a hand revolving motion, and

the movement of the pointer in synchronism with the hand motion is a motion of rotating the pointer.

3. The input apparatus according to claim 1, wherein the action quantity is an expansion quantity or a contraction quantity of an icon.

4. The input apparatus according to claim 1, wherein the action quantity is a locus of a movement of the pointer.

5. The input apparatus according to claim 1, wherein the control unit changes the graphical user interface to cause a predetermined manipulation to be executed when the action quantity has reached a predetermined quantity.

6. The input apparatus according to claim 5, wherein the execution of the predetermined manipulation is an expanded display or a contracted display in a position where the pointer is indicated.

7. The input apparatus according to claim 5, wherein the execution of the predetermined manipulation is a selection of an arbitrary selection item on which the pointer is displayed, from among a plurality of selection items.

8. The input apparatus according to claim 1, wherein

the control unit moves a pointer so as to be in synchronism with the hand motion detected by the action detection unit, and

if the pointer is within a predetermined display region, the control unit changes the graphical user interface so as to indicate an action quantity which corresponds to a quantity of the pointer movement.
