Haptic feedback projection system
First Claim
1. A haptic feedback projection system for transmitting impulses and vibration patterns onto a touch sensitive display surface comprising:
- a a plurality of impulse generators for propagating patterns of vibration at a plurality of points on the periphery of said display surfaceb a control means for synchronizing and triggering impulse and vibration patterns from said impulse generators on the basis of user interaction with said displayc a means of storing and allocating said impulse and vibration patterns to onscreen eventsWhereby said control means, upon detecting user interaction with said display surface, triggers said impulse generators with said allocated and stored patterns such that the cumulative effect detected by a user in contact with said display surface enhances the tangibility and facility of use of on-screen objects and controls to which said impulse and vibration patterns are allocated.

Abstract
This Haptic Projection System (HPS) synchronizes single impulses and vibrations transmitted through the surface material of the touch sensitive display. Impulse generators spaced equally around the edges of the screen can, by adjusting their relative intensities and timing, focus the impulses or vibrations to an approximate point, or series of points out on the screen surface. By focusing convergent haptic vibration patterns on the appropriate location, a sense of tactility, solidity, shape and even resistance and texture can be imbued in on-screen objects and controls being manipulated anywhere on the display surface.
