Mathematical Modelling of Haptic Touchscreens

Haptic keyboards for touchscreen mobile devices would increase the accuracy of users typing, allow touchtyping and increase the satisfaction of users interacting with the devices. We report the results of a feasibility study of one method of implementing such haptic keyboards: driving transverse waves of the touchscreen using piezoelectric transducers mounted at the edges. Our results, while very preliminary, do suggest that this approach is feasible, and that a more detailed investigation is worthwhile.
