A computing device having a human/machine interface is disclosed. An input device (10) has a plurality of keys (T, 1, 2, 3, 4) each corresponding to a separate digit of the human hand. The keys (T, 1, 2, 3, 4) are arranged to match the relative sequential relation of the digits. The input device (10) is coupled to a processor device (30), in turn coupled to a visual display device (50). The processor device (30) receives instructions or data from the input device (10) and outputs information to be displayed to the display device (50). The processor device (30) is programmed to cause the visual display of indicia (60-70) wherein each indicium represents a user initiated instruction or data input and is displayed in one-to-one correspondence with the sequential relation of one or more of the keys (T, 1, 2, 3, 4). |
