Telecommunication pointing device
First Claim
1. A telecommunication pointing device, comprising:
- a chassis;
a transmission interface control unit, which is disposed in the chassis, communicably connecting the pointing device with a computer mainframe for exchanging information;
a cursor detection and control unit disposed in the chassis for detecting and calculating the moving direction and distance of the pointing device, converting the calculated results into coordinate signals of the cursor, and transferring the calculated results to the computer mainframe through the transmission interface control unit;
an audio control unit disposed in the chassis for receiving the audio signals from the computer mainframe through the transmission interface control unit, or transferring the audio signals to the computer mainframe through the transmission interface control unit;
whereby after preinstalling a driver program of network telephone on the computer mainframe, the transmission interface control unit automatically terminates the connection of the transmission interface control unit and the cursor detection and control unit when there is an incoming network phone call, and at the same time, initiates the connection with the audio control unit, thereby converting the pointing device into a network telephone.

Abstract
The present invention is to provide a telecommunication pointing device comprising a transmission interface control unit (e.g. a USB interface control unit), a cursor detection and control unit and an audio control unit are disposed in a chassis thereof, wherein the transmission interface control unit is communicably connected with a computer; the cursor detection and control unit detects the position of the pointing device, converts the detected position into coordinate signals of the cursor and then transfers the coordinate signals to the computer; and the audio control unit receives or transmits audio signals from or to the computer, such that when a driver program of the network telephone is executed on the computer mainframe, at least a function key disposed on the pointing device can be employed to convert the telecommunication pointing device between a normal pointing device and a network telephone, achieving the purpose of being both an input device and a network telephone.
