ABSTRACT:
A cursor control device includes a single key cursor control which utilizes pressure sensitive resistors for controlling cursor movement. Pressure sensitive resistors are arrayed so as to provide an output corresponding to the magnitude and direction of an applied input pressure. Input pressure is transmitted to these resistors by a means for actuating these devices. The means for actuating can include a single key which incorporates functionality of both up, down, left and right cursor control keys and pointing devices to produce horizontal, vertical, diagonal and curvilinear cursor movement. Cursor control device offers mechanically simple, low cost construction, and can be incorporated onto many keyboard constructions. Cursor control device can be positioned on keyboards in many locations as best suits individual applications. Cursor control device can also be incorporated into other devices which require cursor control such as electronic mice.
