ABSTRACT:
An input device is described for generating a keystroke signal. A dome shaped to conform to the shape of a human hand at rest is supported to slide along a generally planar base top. The position of the dome on the base top, which is divided into sectors, is sensed, each sector correlatable with a keystroke signal. A system is also provided for outputting two position signals that are then correlatable into a unitary keystroke signal.
