Abstract
There is provided a hybrid pointing device including an optical navigation module, a pointing module and a switching module. 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. The pointing module is configured to detect a movement between the hybrid pointing device and a working surface. The switching module is configured to active the optical navigation module or the pointing module according to a deformation of a touch plate.

A hybrid pointing device, for being operated by a user on a surface, the hybrid pointing device comprising:
- a transparent touch plate on a top surface of the hybrid pointing device;
- 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 beams to the transparent touch plate;
- and
- an image sensor configured to capture an image covering the transparent touch plate;
- and
- a processor configured to detect a deformation of the transparent touch plate when at least one finger of the user presses thereon and to identify gestures according to a position information of at least one light spot in the image caused by the at least one finger in contact with the transparent touch plate.
A hybrid pointing device, for being operated by a user on a surface, the hybrid pointing device comprising:
- a transparent touch plate on a top surface of the hybrid pointing device;
- a light source configured to illuminate the transparent touch plate;
- a first image sensor configured to capture a first image of the surface;
- a second image sensor configured to capture a second image covering the transparent touch plate;
- and
- a processor configured to calculate a movement of the hybrid pointing device relative to the surface according to the first image, to detect a deformation of the transparent touch plate according to the second image and to identify gestures according to a position information of at least one light spot in the second image caused by at least one finger of the user in contact with the transparent touch plate.
