The touch interface goes back as far as the early days of mobile devices to the Apple Newton and Palm Organiser. Elliptic Labs now add non-touch to the mobile user interface with ultrasound gesture recognition. Todd gets a demo from Laila Danielson, CEO.
Elliptic Labs use an ultrasonic speaker to create a sonic field around the mobile device. Moving a hand in front of the device creates ultrasonic echoes which are picked up by microphones and the changes in echo patterns are converted into gestures. For example, waving a hand from left to right scrolls a picture gallery. Moving a hand closer to the phone brings up additional information on a film or movie.
It’s currently a prototype device being shown to OEMs so expect the technology to appear on mobile devices in the next year or two.
