Modeling and Experimental Evaluation of Haptic Localization Using Electrostatic Vibration Actuators

Touch screen devices have become ubiquitous in modern day-to-day lives. While smaller touchscreen provide enough user engagement with meaningful haptic feedback, large touch still lack stimulation. Existing literature for surface vibrotactile localization uses many actuators and conventional boundary conditions. Previous numerical studies on do not address multi-frequency excitation. This research proposes a new spring-damper condition bar-type display. Subsequently, mechanical model of the bar multiple-electrostatic vibration is developed using material damping information Simultaneously, an experimental setup validation model. An optimization technique to localize rendering at multiple selected zones proposed. It has been established that by varying frequencies excitation two electrostatic resonant actuators, localizable feedback can be generated across length bar. The results corroborate simulation results. Finally, proposed strategy multi-zone experimentally verified.
