To set up your picture password, you then place your gestures on the field we create. Individual points are defined by their coordinate (x,y) position on the grid. For the line, we record the starting and ending coordinates, as well as the order in which they occur. We use the ordering information to determine the direction the line was drawn in. For the circle, we record a center point coordinate, the radius of the circle, and its directionality. For the tap, we record the coordinate of the touch point.

This is clever.
