Abstract
Apparatus and methods for creating a virtual push button comprise a touch sensitive orthogonal data field input device useably connected within a computing system in which a touch action at the device generates a stream of data related to the location within the field of the touch action. The orthogonal data field input device includes circuitry for sensing the onset of a first touch action and for monitoring the continuity thereof; and the computing system including a second condition sensor for sensing the occurrence of a second predetermined condition; and, computing circuitry for generating the virtual push button upon the concurrence of touch action continuation and the occurrence of the second predetermined condition.
