There’s no denying that capacitive, multi-touch screens have revolutionized how we interact with mobile devices; we’re miles away from the stylus-controlled interfaces of Windows Mobile devices of years past. While some of us may not get more involved than single-finger swipes and pinch-zooming, there’s a lot more power available to the user willing to learn a few extra gestures. If that’s your cup of tea, in the future you may wish to look to Qualcomm, which recently acquired a bunch of gesture-related IP from GestureTek and has plans to integrate that technology into upcoming Snapdragon chips.
Snapdragon chips using GestureTek features could theoretically be able to quickly and more accurately recognize gestures within touchscreen input, and process that data accordingly. This could mean support for more elaborate, multi-touch gestures for specific tasks. Of course then, you run into into the problem of diminishing returns; at what point does adding additional custom gestures to an app become more distracting than useful? Even still, the problem of having too much gesture-processing power at out disposal sounds like one we’d be happy to deal with.
