Abstract

An input system for a computer includes a portable device and a conversion device connected between the computer and the portable device. The portable device generates control signals in the manner of a keyboard or mouse to invoke computer functions. When a format or protocol communication type between the portable device and conversion device is different from the communication type between the conversion device and the computer, the conversion device converts the control signals to converted signals in compliance with the existing communication type between the computer and the conversion device.

Claims

1. An input system for a computer, comprising:

a portable device outputting a control signal through a first interface, the portable device comprising;

a keyboard module outputting a key signal;

a touchpad module outputting a touching signal; and

a controller connected to the keyboard module and the touchpad module, and comprising;

a receiving unit receiving the key signal and the touching signal; and

a decode unit decoding the key signal and the touching signal to generate the control signal; and

a conversion device comprising;

a second interface connected to the first interface of the portable device;

a third interface connected to a fourth interface of the computer; and

a processor comprising a delivery unit and a determination unit, wherein the determination unit determines communication types of the first and fourth interfaces, the delivery unit transmits the control signal from the portable device to the computer in response to the communication types of the first and fourth interfaces being the same.

2. The input system of claim 1, wherein the conversion device further comprises a conversion chip, wherein when the communication type between the first and the second interfaces is different from the communication type between the third and fourth interfaces, the converting chip converts the control signal to a converted signal complying with the communication type between the third interface and the fourth interface, and the delivery unit transmits the converted signal to the computer through the third and fourth interfaces.

3. The input system of claim 2, wherein the communication type between the first and the second interfaces is same with the communication type between the third and fourth interfaces, and the first to fourth interfaces are universal serial bus (USB) interfaces.

4. The input system of claim 2, wherein the communication type between the first and the second interfaces is different from the communication type between the third and fourth interfaces, and the first and second interfaces are universal serial bus (USB) interfaces, the third and fourth interfaces are person system/2 (PS/2) interfaces.

5. An input method for a computer, comprising:

connecting a portable device to the computer with a conversion device;

obtaining button signals and touching signals from the portable device by the conversion device;

decoding the button signals and the touching signals to generate control signals by the conversion device; and

transmitting the control signals to the computer through the conversion device.

6. The input method of claim 5, wherein the step “

transmitting the controls signal to the computer”

comprises;

determining communication type between the computer and the conversion device;

determining whether the communication type between the computer and the conversion device is same with the communication type between the conversion device and the portable device; and

transmitting the control signal to the computer in response to the communication type between the computer and the conversion device being same with the communication type between the conversion device and the portable device.

7. The input method of claim 6, further comprising:

converting the control signal to a converted signal by the conversion device in response to the communication type between the computer and the conversion device being different from the communication type between the conversion device and the portable device; and

transmitting the converted signal to the computer by the conversion device.
