Abstract: The wireless human input device comprises at least one wireless human transmitting unit and a wireless human receiving unit. The wireless human transmitting unit generates leading signals and data signals and transmits the signals to the wireless human receiving unit. The wireless human receiving unit receives all of the leading signals and identifies the data signals based on the leading signals so as to distinguish the data signals being transmitted by which wireless human transmitting unit.

Abstract: The pointing input device includes: keys to generate key variation signals, a displacement generating means to generate displacement signals, a controller connecting the keys and the displacement generating means to receive the key variation signals and the displacement signals. The device is characterized by that: when the pointing input device is in a first working mode, the controller receives the key variation signals and the displacement signals and converts them into corresponding pointing data signals; and when the pointing input device is in a second working mode, the controller converts the key variation signals and the displacement signals into corresponding hotkey signals of a keyboard according to the direction and the speed of displacement of the key variation signals and the displacement signals.
