Pointing input device imitating inputting of hotkeys of a keyboard
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.
