ABSTRACT:
A system that allows a user to spotlight a region of particular interest in a large-scale display, such as a wall panel display. The spotlight can be a circular or other shape area around which the display is de-emphasized, such as by being darkened or blurred outside the circle. The spotlight can be moved by the user moving a cursor positioned in the circle. When the cursor encounters an edge of the circle the spotlight is moved in the direction of cursor movement. As the cursor is moved the outside region has less de-emphasis. When the movement is stopped the outside region is darkened to the maximum. A spotlight beam or other attention directing area of emphasis can be used to help focus a viewer's attention on the spotlight. The spotlight can follow objects in a scene as they move.
