Abstract text

An input device of a computer system and a method for operating the computer system are provided. In the method for operating the computer system, a motion state of the input device in three-dimensional space is detected first. Then, a predetermined code is generated at an operation terminal or a main body terminal of the computer system according to the motion state of the input device. Afterwards, the predetermined code is converted to a corresponding object code, and the object code is sent to the main body terminal of the computer system to make the computer system operate according to the object code.
