1. A computer input device, comprising:
- a body and a movement-detecting module coupled to the body, said movement-detecting module being a trace-detecting module that measures the velocity of a moving object,wherein when the velocity exceeds a predetermined threshold, the movement-detecting module generates a signal that causes automatic scrolling,wherein the body has a micro control unit, and the trace-detecting module has at least a light pervious area and a trace-detecting unit;
the trace-detecting unit further having at least a light source, and a sensor; and
wherein the light source projects a light beam to the light pervious area, and the sensor detects a reflected light beam;
a velocity of the object on the light pervious area being sensed by the sensor.

Abstract
A computer input device includes a body and a trace-detecting module coupled to the body. The body has a micro control unit (MCU), and the trace-detecting module has at least a light pervious area, and a trace-detecting unit. The trace-detecting unit further has at least a light source and a sensor. The sensor senses a reflected light beam caused by movement of a user'"'"'s digit movement on the light pervious area at a velocity which can be sensed by the sensor. If the velocity exceeds a threshold stored in the MCU, the MCU executes automatically scrolling.

10. A method for scrolling an application on a computer display by a computer input device, comprising the steps of:
detecting a velocity of an object; and
if the velocity exceeds a predetermined threshold, executing an automatic scrolling, wherein the computer input device has at least a light pervious area, a light source and a sensor for detecting the velocity, and a micro control unit that stores the predetermined threshold and compares it with detected velocity.- View Dependent Claims (11, 12, 13, 14, 15)

16. A method for scrolling an application on a computer display by a computer input device, comprising the steps of:
-
detecting a velocity of an object; and
if the velocity exceeds a predetermined threshold, executing an automatic scrolling,wherein the velocity is determined by the variation of a reflected light beam from the object'"'"'s movement. - View Dependent Claims (17, 18, 19, 20, 21)
