Advanced Multitouch: Writing Without a Stylus and More

More Apple patent applications were published today, though many rehash earlier patents applications that were revealed in November. Still, the technology behind the advanced multi-touch are impressive enough to bear repeating.

The patent, originally published in November 2007, describes methods for interpreting a remarkable amount of gestures that allow for a rich vocabulary -- such as interpreting the use of an imaginary stylus. The possibilities are best summarized by this description from PCJoint::

- Need to move a cursor across the screen? Just slide your finger and it goes.
- Want to enter text? Just start typing and the text is there. You even get the touch feedback as if really pressing the keys.
- Need to erase some text? Use the backspace or just slide the finger backwards
- Have to write or draw something? Just pretend you hold a stylus or pen in your hand and start writing/drawing.
- If that is still not good enough, pick up the real stylus and start writing with it.
- All these cool touch gestures that Apple has implemented in iPhone and is exploring further? You know, scrolling, zooming, rotating & moving objects, etc; They are here too
- 3D object manipulation? Select a few 3D objects on the screen and use all 5 fingers on both hands to play with them.
- Want to take a break to relax and afraid to put your hands on the touch surface? Dont worry Multi-touch 2.0 thingie knows that and does not pay attention to your resting palms or fingers

The surface used would be a larger curved surface, pictured above, resembling Fingerworks' TouchStream keyboard.
