摘要：
A pointing device includes a moveable puck, a first surface on which a puck field of motion is defined, and a controller. The total distance the puck can move from its centered or resting position is divided into N regions using one or more transition points. Each transition point corresponds to a puck position at which the cursor speed changes. The controller determines the position of the puck within the puck field of motion and, based on the current puck position and at least one transition point, the controller determines a speed at which the cursor is to be moved.
