Texas Instruments was showing gesture recognition back at MWC 2010, but with OMAP4 the system has really come of age. The chipset - to be found at the heart of the LG Optimus 3D and the BlackBerry PlayBook - uses the camera support to track hand and arm movements; TI showed a demo where a Blaze developer unit could respond to waves to navigate through a photo gallery.

By rotating and clenching a fist in front of the camera, the gallery could be zoomed and panned around in 3D space. TI envisage it being used in HD-capable smartphones, plugged into an HDTV and then gestures for navigating through content, allowing you to control your media without, say, getting up from the couch or reaching for the remote.
However, in future a single device - with a high powered OMAP5 chipset - could run a Minority Report style gesture system, well exceeding the power of an Atom CPU in a smartphone-scale form-factor. OMAP5 devices are expected to reach the market by the holiday 2012 season.
