ABSTRACT:
A computer terminal user interface control is provided for allowing input from an operators non-dominant hand. Force sensitive transducers are provided at right angles to one another. Forces applied to these transducers move a tool set to various sub-portions of a video display device. The user's dominant hand is then free to select from various sub-areas of the tool window positioned by the non-dominant hand in a simple and efficient manner.
