Wireless handheld input device
First Claim
1. A wireless handheld input device, comprising a microprocessor, a signal transformation module, a wireless transmission/reception module, an audio input module, an audio output module, a keyboard and a pointing touch pad, wherein:
- the microprocessor is connected to the signal transformation module, the audio input module, the audio output module, the keyboard and the pointing touch pad, the microprocessor being capable of processing control signals entered from the audio input module, the keyboard and the pointing touch pad, whereby after the control signals are completely processed, the results are then sent to the signal transformation module;
the signal transformation module receives the control signal sent from the microprocessor and transforms the signals, whereby the transformed signals are sent to the wireless transmission/reception module, and input to the microprocessor;
the wireless transmission/reception module receives the transformed signals sent from the signal transformation module and wirelessly output the transformed signal to an electronic product that has a receiver, thereby controlling the electronic product and receiving the signals sent from the remote electronic product via the wireless transmission/reception module 13 and transferring the received signals to the signal transformation module;
whereby the audio input module is provided for users to input audio signals into the microprocessor, the audio output module is provided for playing the audio signals sent from the microprocessor, the keyboard connected to the microprocessor is provided for users to input all possible control commands, and the pointing touch pad connected to the microprocessor is provided for users to control the movement of a pointer by moving a finger on the surface of the pointing touch pad.
