Abstract (Summary)

Touchscreens are arguably one of the most prevalent electronic devices today. They have a wide range of applications in Education, Medicine, Telecommunications, Entertainment and Commerce.

Variable Friction Touchscreens are a promising new class of touchscreens that enable users to "feel" virtual environments. The last decade has seen these touchscreens develop to production of commercially available prototypes. There, however, remains significant barriers in the design of these touchscreens that, if eliminated, would propel these devices to new levels of applications.Two of these challenges are a small bandwidth of surface textures inhibiting the range of realistic texture perceptions that can be felt by the user and an inability to control the location of texture perceptions felt on the surface of these touchscreens by users.

In this work, we propose Modal Superposition and Active boundary conditions as two methods of refining and controlling texture perceptions generated by these touchscreens.
