Hand-movement-sensing input device
First Claim
Patent Images
1. 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.

Abstract
A hand-movement-detecting input device includes a body; and an image-position detecting device located on the body, by which the image-position detecting device detects movement of at least a portion of the user'"'"'s hand so as to generate a cursor-moving signal or a button-click signal for use by a computer, without the need for physical manipulation of a device such as a mouse or keyboard.

5. A method of generating signal for an input device, comprising:
-
capturing a first image indicative of a horizontal position of a hand of a user using a plane-position sensor and capturing a second image of at least a portion of the hand using an altitude-position sensor;
detecting movement of the hand in a horizontal plane based on the image captured by said plane-position sensor;
identifying a feature in the image captured by said altitude-position sensor;
determining coordinates of the feature;
comparing coordinates of the feature to detect movement of the portion of the hand of the user in a vertical direction;
generating a cursor-moving signal based exclusively on said movement of the hand in the horizontal plane; and
generating a button-click signal based exclusively on said movement of the portion of the hand of the user in the vertical direction.
