    摘要: The invention relates to an input device having multifunctional keys, wherein the different functions are triggered by varying the pressure on the keys or by varying the depth to which the key is depressed or the distance it is moved (see figure 3). The input device requires substantially fewer keys than a standard qwerty keyboard to input data and requires less physical space. In certain instances the keyboard can be operated with one hand.
