Abstract:
A hand-moving input device, comprising:a plane-position detecting unit for detecting movement of a hand in a horizontal plane, wherein generation of a cursor-moving signal is based exclusively on an output of said plane-position detecting unit; an altitude-position detecting unit for detecting movement of a portion of the hand in a vertical plane, wherein the altitude-position detecting unit includes an identification unit for identifying a feature in an image of the hand, an altitude-coordinated encoding unit for determining a position of the feature, and altitude-coordinated comparing unit for detecting vertical movement of the feature, and a button-click signaling unit for generating the button-click signaling unit for generating the button-click signal in response to movement of the feature, wherein generation of a button-click signal is based exclusively on an output of said altitude-position detecting unit.
