Latex overlays inflate to provide the tactile sensation of pressing a button
It seems increasingly rare to see a new gadget these days without a touchscreen. However, touchscreens' versatility is both the technology's biggest strength and its weakness. We've lost the tactile memory we associate with our television remote controls or old cell phones, where we knew and could feel exactly where the buttons we needed were without bothering to look. Researchers at Carnegie Mellon University are trying to combine the benefits of both, by adding a latex overlay on top of a touchscreen that inflates to create a tactile surface.
