Patent ID: 7576726

Claim:
A dual-positioning controller for controlling movement of an indicium on a display of an electronic device, said dual-positioning controller comprising: a coarse controller for controlling a first relative motion parameter producing coarse movement of said indicium relative to content displayed on said display, said coarse controller being a first puck-type pointing device including a first surface having a first puck field of motion defined thereon and a first moveable puck operable to move within said first puck field of motion, wherein a displacement of said first moveable puck within said first puck field of motion produces said coarse movement; and a fine controller for controlling a second relative motion parameter producing fine movement of said indicium relative to said content on said display, said fine controller being a second puck-type pointing device including a second surface having a second puck field of motion defined thereon and a second moveable puck operable to move within said second puck field of motion, wherein a displacement of said second moveable puck within said second puck field of motion produces said fine movement, wherein said indicium comprises a cursor displayed on said display and wherein said first relative motion parameter is a velocity of said cursor on said display, said velocity of said cursor being determined exclusively by the distance and the direction of a displacement of said coarse controller.
