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.

If the velocity exceeds a threshold stored in the MCU, the MCU executes automatically scrolling at a predetermined scrolling speed.

A sound-activated wake-up device generates a wake-up signal for ending a sleep-mode in response to the sound of friction between an operating platform and an input device, or the sound of touching of the input device by the user. The wake-up device includes a sound detecting unit and a signal amplifying/comparing unit, and sound filtering structures and/or circuitry so as to prevent ambient sounds from activating the wake-up device.
