Abstract
An improved structure wireless mouse device comprised of a base board connected to a host computer and a mouse device, wherein no physical signal cable is present between the mouse device and the base board. The mouse device and the base board are equipped with internal circuitry that enables electric power from the host computer to be conveyed to the transmit/receive antenna of the base board and after reception by the mouse device, the electrical energy is supplied to its internal circuit. The two-dimension signal generated as the mouse device is moved on the base board is received by the transmit/receive antenna of the base board and transferred to the host computer to thereby enable control of the host system. The resulting wireless mouse device structure of the present invention differs significantly from conventional wireless mouse device arrangements in that the shortened interactive operating distance not only results in error-free signal detection and zero RF signal interference performance, but also does not require batteries, has a reduced malfunction rate, and is lightweight.
