A touch screen controller identifies a multi-touch gesture associated with a display feature such as scale or orientation. The touch screen controller applies a discrete value change to the display feature from an ordered set of discrete values. The number of points of contact in the multi-touch gesture may be interpreted by the touch screen controller as step changes in the ordered set of discrete values when applying the value change to the display feature.
