Synaptics has a new 'experimental' phone called the Fuse. You can interact with the phone by squeezing, gripping, flexing and tilting the phone. The device melds multiple technologies such as multi-touch capacitive sensing, haptic feedback and proximity sensing. This is just a prototype that will not be made into a product. Synaptics just wanted a showcase for their technologies.
The Fuse has a multi-touch, 3.7" 480x800 OLED display.
