By integrating their ultrasound technology into mobile devices, researchers at Elliptic Labs have developed smartphones able to respond to gesture commands—and they may be on the market soon.
The ultrasound sensors work by bouncing high-frequency sounds off the user's hand and calculating the time it takes for the sound to return—thus determining the position of the hand in 3D. This technology, called "Multi Layer Interaction," enables the device to respond to commands based on the distance of the hand. For example, a lock screen widget will display calendar appointments when the hand is farther away, then switch to emails and finally the lock icon when the hand is closer. The responsive field extends all around the device, and the system consumes very little power compared to some of the other gesture-recognition systems currently in development.
