Gestures for touch sensitive input devices

Abstract

Methods and systems for processing touch inputs are disclosed. The invention in one respect includes reading data from a multipoint sensing device such as a multipoint touch screen where the data pertains to touch input with respect to the multipoint sensing device, and identifying at least one multipoint gesture based on the data from the multipoint sensing device.

1 . A method of simulating a keyboard, comprising:
 providing a display and a touch screen positioned over the display;   displaying a keyboard on the display, the keyboard including at least a first and a second key;   detecting the presence of a first object over the first key and a second object over the second key at the same time; and   generating a single control function in response to the detection of said first object over the first key and said second object over said second key.   
   
   
       2 . The method as recited in  claim 1  wherein the first and second objects are portions of one or more hands. 
   
   
       3 . The method as recited in  claim 1  wherein the first key is a modifying key that modifies the second key. 
   
   
       4 . The method as recited in  claim 3  wherein the first key is a shift key, control key or alt key.
