Abstract
A gesture recognition method includes detecting multiple pointers in close proximity to a touch surface to determine if the multiple pointers are being used to perform a known gesture. When the multiple pointers are being used to perform a known gesture, executing a command associated with the gesture. A touch system incorporating the gesture recognition method is also provided.

2. An event generation method comprising:
-
detecting a pair of pointers brought into contact with a graphical object displayed on a touch surface and the subsequent relative movement of said pointers along said touch surface; and generating a scaling event when the subsequent relative movement of said pointers along said touch surface comprises relative diagonal movement. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. An interactive input system comprising:
-
at least one imaging device aimed to look generally across a touch surface; and processing structure processing image data captured by said at least one imaging device and being configured to; detect a pair of pointers brought into contact with a graphical object displayed on said touch surface and the subsequent relative movement of said pointers along said touch surface; and generate a scaling event when the subsequent relative movement of said pointers along said touch surface is relative diagonal movement. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
