Synaptics on Monday revealed a concept phone design that shows input methods beyond touchscreens. The Fuse, co-designed by TheAlloy and The Astonishing Tribe, has a multi-touch capacitive screen but also embeds grip and touch sensors on the sides that can recognize when the phone is squeezed or touched beyond its display. It would even have basic touch control from the back of the phone to provide control without blocking the screen itself.
