---- PROTOTYPE --------- PURPOSE: Researchers from Carnegie Mellon University, Graduate student Chris Harrison and Professor Scott Hudson, have designed a prototype of an alternative touch-screen technology surface which allows for display capabilities of a normal touch screen; but also produces physical pop-up buttons for tactile interaction. This prototype is ideal for persons who are blind or visually impaired. The prototype design incorporates a screen with hidden latex air bubbles. An air chamber is created by layering several specially-cut pieces of clear acrylic. Then a thin sheet of translucent latex is draped on top of layers of acrylic to act as a deformable projection surface. The air chamber is negatively or positively pressurized to create small pop-up buttons that mimic the feel of real buttons/keys. TITLE: Providing dynamically changeable physical buttons on a visual display.
