1. A method for determining a touch gesture in a touch sensitive device comprising: determining a plurality of consecutive touch point coordinates of a multi-touch event on an interaction surface by analyzing each touch point coordinate one at a time as sensed single touches during the touch gesture; determining that the plurality of consecutive touch point coordinates satisfies the relationship: 
 y i =ax i +b±Δ 
 or 
 x i =c±Δ wherein y i and x i correspond to touch point coordinates of touch point i of the plurality of consecutive touch point coordinates, a is a first constant, b is a second constant, c is a third constant, and Δ is a fourth constant, and wherein a is limited to discrete values of: less than 50, less than 10, or less than 5; determining a multi-touch touch pattern based on the relationship among the plurality of consecutive touch point coordinates; and attributing a predetermined action corresponding to the multi-touch touch pattern.
