Abstract
The present invention provides a computer cursor control system comprising a touchpad device and a cursor control program. The cursor control program displays a virtual pointer on a screen according to a finger's touch on the touchpad device and simultaneously moves a computer and the virtual pointer according to the finger's movement on the touch pad device. Finally, the compute cursor is moved to the virtual pointer's position responding to a switch signal generated by the touchpad device.
Claims6
A computer cursor control system, for controlling movement of a computer cursor displayed on a computer screen connected to a host, the system comprising:
- a touchpad device, electronically connected to the host and comprising a pad, a left key and a right key, for generating a relative displacement signal according to a finger's touch on the pad and responding to the finger's operation on the touchpad to generate a switch signal;
- and
- a cursor control program, installed in the host for executing the following steps:
- displaying a virtual pointer on the screen at a first virtual pointer position according to a touch position touched by the finger on the pad, the first virtual pointer position and the position of the cursor being independent of each other;
- moving the virtual pointer from the first virtual pointer position according to the relative displacement signal;
- and
- moving the cursor to the position of the virtual pointer when receiving the switch signal.
A cursor movement control method, for controlling movement of a cursor displayed on a screen, wherein the cursor movement is determined by a finger's displacement on an input device, comprising:
- displaying a virtual pointer on the screen at a first virtual pointer position according to a touch position touched by the finger on the input device, the first virtual pointer position and the position of the cursor being independent of each other;
- moving the virtual pointer from the first virtual pointer position according to the finger's displacement on the input device;
- and
- responding to a switching signal to move the cursor to the position of the virtual pointer.
