The 3D touchless interface by Elliptic Lab doesn’t need you to wear any special gloves with sensors. Just point your fingers at the screen, then you can manipulate the objects in 3D. Amazingly, you can stay up to 5 feet away from the screen.

According to the lab, the technology is compact enough to be embedded in portable gadgets. Reps from the lab will show off this 3D touchless technology in the upcoming GDC show in San Francisco 3rd week of February.
