Apple Depicts Advanced Multitouch Gesturing Control Panel in Mac OS X
Apple's notebooks already contain what we presume to be "basic multitouch" with two-finger scroll, rotate, and zoom, but "advanced multitouch" has not yet been seen in shipping products.
The patent application depicts how one could customize these advanced gestures for Expose and Dashboard, by using four finger swipes up/down/left/right:
File operations, such as Open, New, Save and Close using gestures based on your Thumb and Forefinger:
And even editing operations such as Copy, Cut, Paste, Undo, Select All, Tab, and Cancel using gestures based on your Thumb and Two Fingers:
They also claim to be able to distinguish between various combinations of fingers, including adjacent and non-adjacent finger presses. In particular, they point out that the pinky finger when applied sideways to the trackpad (as in the bottom of a fist) generates a unique pattern and could be used for its own customizable functionality: such as adjusting volume or putting the computer to sleep.
Over the past few years, numerous multitouch patent applications have been revealed Apple's ongoing work on gesture computing. Apple has been making small and steady steps at introducing the multitouch interface -- first in the iPhone, and now in the MacBook Air. Apple is expected to expand this basic multitouch functionality to the remainder of their notebook product line.
