The logical next step from touch screens is touch environments. This is the first step, via the smart phone, to move in that direction. What this new interface can immediately allow is to have a table or wall become a white board that is captured on the phone. A number of other functionalities will certainly follow. This is a good, incremental next step toward toward fuller use of the computing capability of the smart phone to help shape our environments and to capture them in a nextgen manner.
