HYBRID POINTING DEVICE
First Claim
1. A hybrid pointing device, for being operated by a user on a surface, the hybrid pointing device comprising:
- a first module, configured to sense a movement of the hybrid pointing device relative to the surface;
a second module, comprising;
at least one light source, configured to emit light; and
at least one image sensor, configured to capture an image containing at least one interruption of at least one object operated by the user from blocking the light emitted by the light source; and
a processor, configured to identify gestures of the object according to a variation of the interruption on the image.

Abstract
The present invention discloses a hybrid pointing device including an optical navigation module and a pointing module. The optical navigation module is configured to replace the conventional buttons of a convention pointing device, such as an optical mouse or a trackball mouse. The optical navigation module is configured to sense gestures of at least one object operated by a user to activate commands associated with particular programs running on the host. Since the optical navigation module is only configured to sense gestures of the object but not the movement of the hybrid pointing device relative to a surface, the resolution thereof is aimed to be sufficiently high enough for sensing gestures and no need to be relatively high.

11. A hybrid pointing device, for being operated by a user on a surface, the hybrid pointing device comprising:
-
a first module, configured to sense a movement of the hybrid pointing device relative to the surface; a second module, comprising; a light source, configured to emit light; and an image sensor, configured to capture an image containing at least one light spot of at least one object operated by the user from reflecting the light emitted by the light source; and a processor, configured to identify gestures according to a position information of the light spot on the image. - View Dependent Claims (12, 13, 14, 15)
