Folks in MS Research make the precise gesture recognition possible almost anywhere

It’s a UIST paper this year.

Here is the brief description from their website.

Digits: Freehand 3D Interactions Anywhere Using a Wrist-Worn Gloveless Sensor describes technology that recovers the full 3-D pose of the user‘s hand. The paper—co-authored by David Kim, a Microsoft Research Ph.D. Fellow from Newcastle University‘s Culture Lab;Otmar HilligesShahram IzadiAlex Butler, and Jiawen Chen of Microsoft Research’s U.K.-based Cambridge lab; Iason Oikonomidis of Greece’s Foundation for Research & Technology; and Patrick Olivier of Newcastle University’s Culture Lab—describes Digits, a wrist-worn sensor for freehand 3-D interactions on the move. By instrumenting only the wrist, the user’s entire hand is left to interact freely without “data gloves,” input devices worn as gloves that are most often used in virtual-reality applications to facilitate tactile sensing and fine-motion control. The Digits prototype, whose electronics are self-contained on the user’s wrist, optically image the entirety of the user’s hand, enabling freehand interactions in a mobile setting.
