Abstract
The development of haptic touchscreens, that is touchscreens with the ability to mimic the feel of a real keyboard, would be a significant advance in the mobile phone and tablet market. This report investigates one possible route to developing such touchscreens using piezoelectric actuators placed at the edge of the screen and driven at a range of frequencies.
The report addresses the following questions: Can an array of piezoelectric transducers placed round the edge of the screen create localised vibrations in the right physiological range to produce the sensation of a keyboard? If so how many transducers are needed? Where should they be placed? How should they be driven? We consider both the excitation of longitudinal and transverse waves but do not discuss surface waves.
