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 computer implemented method for initiating zooming targets via a touch screen, the method comprising:
 displaying an image on a GU;   enlarging the image for a period of time when the presence of an object is detected over the image.   
   
   
       2 . The method as recited in  claim 1  wherein the image is a user interface element. 
   
   
       3 . The method as recited in  claim 2  wherein the user interface element is a control box containing one or more control buttons, and wherein said enlarging includes enlarging the control box and each of the control buttons. 
   
   
       4 . The method as recited in  claim 3  wherein the size of the control buttons correspond to the size of the object or larger so that the control buttons can be easily selected by the object. 
   
   
       5 . The method as recited in  claim 4  further comprising:
 in the enlarged state, generating a control signal associated with the control button when the presence of the object is detected over one of the control buttons.   
   
   
       6 . The method as recited in  claim 1  wherein the object is a finger. 
   
   
       7 . The method as recited in  claim 1  further comprising:
 implementing a gesture input when the presence of one or more objects are detected over portions of the GUI other than the image.
