Abstract:
In a method and module for modifying a pointer signal generated by a 3D point in device and corresponding to motion of the pointing device, an angular velocity generating unit generates an angular velocity of the 3D pointing device based on the pointer signal. A control unit generates a control signal based on the angular velocity generated by the angular velocity generating unit and predetermined angular velocity threshold information. An adjustable low-pass filter is operable within a gain range, and determines a target gain thereof based on the control signal from the control unit. The low-pass filter filters the pointer signal with the target gain determined thereby to generate a modified output corresponding to the pointer signal.
