This area I think could be the most interesting future development with the Pico projectors, it could turn your Smartphone into a 20″ Tablet, by projecting an interactive wall onto any table combined with some kind of gesture recognition (that it detects precisely where you touch the table). No prototypes are shown yet, I think Texas Instruments and their partners should make it a priority to demonstrate that this can be made to work to make this into a leading differentiating hardware feature of future smart phones.
