| 1. A pointing device, comprising:
a first surface having a puck field of motion defined thereon, said puck field of motion being divided into a pointing region
and a function region;
a moveable puck that moves on said first surface;
a controller that determines a position of said puck within said field of motion; and
a display screen that displays a two-dimensional scene and a cursor that moves within said scene in a manner controlled by
said position of said puck when said puck is in said pointing region, wherein said controller causes said scene to change
according to a scrolling function when said puck is in said function region;
a deformable barrier for inhibiting the movement of said puck into said function region, said inhibition being overcome by
a user applying a force to said puck in a direction parallel to said first surface.
