With Untouch SDK, you can develop 3D hand gesture recognition applications by connecting a depth sensor to your mobile phone or PC. Our Riemann SDK can track 26 DoF of the hand, thus detecting the hand gesture and action in a 3D space. In comparison with the traditional interaction such as key or touch, 3D hand gesture recognition is more intuitive and natural, providing users with a new touchless interactive experience.

Demo Video

The developers use PMD pico flexx with Untouch Riemann SDK to show a demo for hand gesture recognition; the demonstration is shown in the above video. If you want to integrate 3D-hand gesture recognition technology into your own application or product, please apply immediately and download our SDK.
