The gestural interface used by Tom Cruise in the movie Minority Report was based on work by MIT Media Lab’s Hiroshi Ishii, who has already commercialized similar large-scale gestural interface systems. However, such systems comprise many expensive cameras or require the user to wear tracking devices on their fingers. To develop a similar yet cost effective gestural interface system that is within reach of many more people other researchers at MIT have instead been working to develop screens with embedded optical sensors to track the movement of the user’s fingers that could quickly make touch screens seem outdated.
