Patent ID: 8519965

Claim:
A multi-touch detection system comprising: a touch panel comprising a first section and a second section, wherein said first section and said second section are formed on a common base and are based on the same physical principle for touch detection; a first sensing subsystem for: separately detecting, at a first time period T 1 , a first coordinate of a pair of coordinates and a second coordinate of said pair of coordinates for a first touch of said first section; and separately detecting, at a successive second time period T 2 following after said first time period T 1 , said first coordinate of said pair of coordinates and said second coordinate of said pair of coordinates for new coordinates of the first touch of said first section; and a second sensing subsystem for: separately detecting, at said first time period T 1 , a first coordinate of a pair of coordinates and a second coordinate of said pair of coordinates for a second touch of said second section, and separately detecting, at said successive second time period T 2 following after said first time period T 1 , said first coordinate of said pair of coordinates and said second coordinate of said pair of coordinates for new coordinates of the second touch of said second section; wherein said first touch of said first section and said second touch of said second section are contemporaneous and in different locations; and a master controller, coupled to the first sensing subsystem and the second sensing subsystem, for interpreting changes in the sensed pairs of coordinates for the first touch of said first section and the second touch of the second section, between the first time period T 1 and the second time period T 2 , as a single multi-touch gesture for entering a command to a display controller.
