PopTouch: A Submillimeter Thick Dynamically Reconfigured Haptic Interface with Pressable Buttons

Herbert Shea, Ayana Mizutani, Amir Firouzeh

The interactions with touchscreens rely heavily on vision: The virtual buttons and virtual sliders on a touchscreen provide no mechanical sense of the object they seek to represent. This work presents PopTouch: a 500 mu m thick flexible haptic display that ...

Dynamic control of high-voltage actuator arrays by light-pattern projection on photoconductive switches

Herbert Shea, Amir Firouzeh, Edouard Franck Vincent Gustave Leroy, Vesna Bacheva, Aiste Balciunaite

The ability to control high-voltage actuator arrays relies, to date, on expensive microelectronic processes or on individual wiring of each actuator to a single off-chip high-voltage switch. Here we present an alternative approach that uses on-chip photoco ...
