Tactus Technology is showcasing its next-gen mobile tactile tech at SID Display Week 2012 in Boston.
A Tactus spokesperson explained to TG Daily that their layer panel is the "world’s first" deformable tactile surface capable of creating dynamic physical buttons that users will actually see & feel before they enter data into their device.
How it works:
The Tactile Layer panel is flat, transparent, dynamic, and adds no extra thickness to the standard touchscreen display since it replaces a layer of the already existing display stack, but when triggered they layer transforms the surface to form buttons and/or shapes with specific height, size and firmness that appear on the surface of the screen. You will physically feel the buttons as if they were keys on a keyboard.
Just think of texting with a keyboard, and then when switching to a game, the screen pops up a D-Pad and A-B buttons.
