Operating Smart Devices from the Space on And Above the Back of Your Hand
Operate your smart watch without touching it! Anders Markussen and Sebastian Boring at University of Copenhagen together with researchers from Max Planck Institute for Informatics and Aalto University of Finland have developed an input method that requires only a small camera to track fingertips in mid-air, and touch and position of the fingers on the back of the hand.

The method relies on a depth sensor that tracks movements of the thumb and index finger on and above the back of the hand. In this way, not only can smartwatches be controlled, but also smartphones, smart TVs and devices for augmented and virtual reality.
They're called the "Apple Watch Series 2", "LG Watch", "Samsung GEAR S3" or "Moto 360 2nd Gen" but they all have the same problem. "Every new product generation has better screens, better processors, better cameras, and new sensors, but regarding input, the limitations remain," explains Srinath Sridhar, a researcher in the Graphics, Vision and Video group at the Max Planck Institute for Informatics.
Together with Christian Theobalt, head of the Graphics, Vision and Video group at MPI, Anders Markussen and Sebastian Boring at the University of Copenhagen and Antti Oulasvirta at Aalto University in Finland, Srinath Sridhar has therefore developed an input method that requires only a small camera to track fingertips in mid-air, and touch and position of the fingers on the back of the hand. This combination enables more expressive interactions than any previous sensing technique.
