ABSTRACT:
In the present invention an input device for use with a digital computer having a video display for displaying the position of an indicator thereon is disclosed. The input device has means for converting rotational motion signals into conventional cursor key signals and also has a plurality of keys which include a numeric keypad and a plurality of control keys. A program controls the input device such that in the event the key signals are supplied, then said key signals are supplied to the computer. However, if no key signal is supplied, then the motion signals are converted into key signals and are then supplied to the digital computer. The input device also can receive the input signal and reprogram the function of the keys in response to that one input signal. Still, the input signal caused by activation of one of the plurality keys can cause the suspension and resumption of the tranfer of the motion signals to the computer. Finally, activation of one of the plurality keys can cause the activation of one or more of the plurality of commands that are displayed normally in the periphery of the display without the device or the indicator being moved to the position of the command.
