Abstract
A pointing device is disclosed in the present invention, which comprises a planar sensing unit, an inertial sensing unit and a controller unit. The planar sensing unit is capable of detecting a movement of the point device moving on a planar surface and generating a planar sensing signal accordingly. The inertial sensing unit is capable of detecting a movement of the point device while it is moving in a free space and thus generating an inertial sensing signal accordingly. The controller unit is coupled to the planar sensing unit and the inertial sensing unit for enabling the same to receive and process the planar sensing signal and the inertial sensing signal. In a preferred aspect, the planar sensing unit is capable of detecting and determining whether the pointing device is operating on a surface or in a free space for selectively enabling the pointing device to operate in a mode of two-dimensional detection or in a mode of three-dimensional detection such that users can apply the pointing device freely without being restricted by a surface or a space, and thus not only the usage convenience of the pointing device is enhanced, but also the applications thereof are broadened.
