Multitouch screens are so versatile and easy to use, why limit them to smartphones and tablets? Researchers have been working for several years to extend multitouch to arbitrary surfaces, but a project called OmniTouch from Microsoft Research and a PhD student at the Human-Computer Interaction Institute at Carnegie Mellon University may bring it closer to reality.
OmniTouch turns body parts and nearby surfaces into touch interfaces. Users can read and reply to an e-mail by touching their hands or a nearby wall, or even use multiple applications at once on multiple surfaces. The results from a user study “suggest our prototype system approaches the accuracy of conventional, physical touch screens, but on arbitrary, ad hoc surfaces,” the researchers say in a [3:24 minute] video.… read more. “OmniTouch turns body parts and nearby surfaces into touch interfaces”
