Abstract

A joystick is used not only to enter input but --by varying resistance-to-movement, by applying a vibration, by moving to a detent position, or by altering joystick dimensions (such as in an expanding hand-hold --also provides tactile feedback to the joystick operator.

Joystick With Tactile Feedback

A joystick is used not only to enter input but --by varying resistance-to- movement, by applying a vibration, by moving to a detent position, or by altering joystick dimensions (such as in an expanding hand-hold --also provides tactile feedback to the joystick operator.

In a specific embodiment, solenoids disposed at angles relative to each other can apply respective forces to a joystick mounted on a swivel in order to impart x- y motion to the joystick. Other mechanical devices may be employed in providing the other proposed physical (tactile) feedback signals.

The interactive joystick may be used in a variety of applications. In a first application, the joystick is used in waveform analysis as a waveform-bumper. In this application, the user selects a point on a graphics screen over which a waveform graph passes. When the graph intersects the selected point, a "bump" (in the form of a vibration or expansion of a ball on the joystick) is sensed by the user.

In a second application, a user can feel ridges and electrostatic potentials in VLSI design or molecular graphics as the joystick vibrates or changes dimensions.

In a third application, quantitative physical measures (such as heat, gravitation, or electrical gradient) may be sensed as the joystick becomes more difficult to move.

In another application, the measure of iteration in an iterated mathematical map may be sensed by the resistance of the joystick to movement.
