A new patent application from Apple, “called ‘Gesture learning’ gives a whole new meaning to gesture expansion. It describes how Apple may go about teaching you a whole new multi-touch gesture language, consisting of hundreds of words. Something like American Sign Language for touchscreens,” Staska reports for Unwired View.

“To describe the possibilities of multi-touch gesture language, Apple splits a single gesture into two phases. The first phase of the gesture includes specific combination of fingers (or other hand parts) that you place on the touchscreen. It’s called chord. Another phase is the movement of the fingers – rotation, translation, scaling, etc. Taken together these phases make a full multi-touch gesture,” Staska reports.

“Well, you can do the math yourself. 25 or more chords with 13 or more possible movements. That’s at least 325 possible gesture combinations for a single hand,” Staska reports.

“Apple proposes a separate interactive multi-touch gesture learning application” Staska reports. “Nothing too complex, just a screen area for the user for assisted experimentation with different gestures, another small animated window showing how to perform the gesture and interactive feedback mechanism, showing how well user is performing the gesture. And to make it more fun, Apple can make a game out of the whole learning process.”
