'ForcePhone' Tech Brings 3D Touch to All Phones

Researchers at the University of Michigan have created software that adds 3D Touch-like functionality to just about any device. The software emits a high-frequency sound from the speaker and uses the microphone to listen to and analyze the sound. The sound changes as people interact with the device and can tell the difference between a light touch and a more firm press, or what happens when the phone is squeezed in various pattern. The benefit of the ForcePhone software is that it doesn't rely on special sensors or technology, and instead uses what's already available inside the phone. "Now this functionality can be realized on any phone," said Kang Shin, Professor of Computer Science in the U-M Department of Electrical Engineering and Computer Science. "ForcePhone increases the vocabulary between the phone and the user. I think we're offering a natural interface, like how you turn a knob. It's the next step forward from a basic touch interface and it can complement other gestured communication channels and voice." Tung plans to demonstrate the technology next month, but hasn't announced any plans to commercialize it. The idea is nearly identical to one implemented by Elliptic Labs earlier this year.
