Abstract
An input device having a movable puck and display screen is disclosed. The puck is confined to move on a puck surface having a puck field of motion defined thereon. The puck field of motion is divided into a pointing region and a function region. A controller determines a position for the puck within the field of motion. The display screen displays a two-dimensional scene and a cursor that moves within the scene in a manner controlled by the position of the puck when the puck is in the pointing region. The controller causes the scene to change when the puck is in the function region. A deformable barrier that inhibits the movement of the puck into the function region can be used to prevent inadvertent changing of the display scene. The inhibition is overcome by a user applying additional force to the puck in a direction parallel to the surface.
