OmniTouch
OmniTouch was developed by researchers Chris Harrison, Hrvoje Benko and Andy Wilson at Microsoft Research in 2011. The work was accepted to and presented at the 2011 ACM User Interface and Software Technology conference. Many major news outlets and online tech blogs covered the technology. It is conceptually similar to efforts such as Skinput and SixthSense. A central contribution of the work was a novel depth-driven, fuzzy template matching approach to finger tracking and click registration. The system also finds and tracks surfaces suitable for projection, on which interactive applications can be projected.
