GelTouch adds a new dimension to touch-sensitive controls
Monday, 20 March 2017 () The problem with a lot of touch-sensitive controls is that the communication is one-way: They can feel you, but you can't feel them.
With touch-screen displays it's easy enough, as the button does what it says on the screen. Not all buttons are designed to be looked at as they are pushed, though. Take video-game controllers or car entertainment systems, for example, or some industrial controls. The user's attention is typically elsewhere when these are operated.
