Video cameras have become integrated into many devices. Intel is looking to take advantage of these video cameras for gesture based interaction. Intel’s Tony Chun describes mobile augmented reality for develping accelerators to be used in smart phones for image recognition and speech recognition. You can hit the link below for a two minute video describing the technology. From Intel’s website:

As video cameras are integrated into more devices from laptops to phones, computer vision capabilities have become increasingly attractive to enable applications such as gesture-based user interfaces and augmented reality. Intel has demonstrated a functional, reconfigurable hardware accelerator to enable advanced vision capabilities on mobile devices. This research from Intel Labs, St. Petersburg explores the automated design of reconfigurable accelerators based on tools-aided application analysis targeting computationally-intensive media workloads such as the SURF object recognition algorithm.
