Pointing device adapted for small handheld devices having two display modes
First Claim
1. A display 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, said puck being characterized by a position within said field of motion;
a controller that determines a position of said puck within said field of motion; and
a display screen having first and second display modes, said display screen displaying a two-dimensional scene in said first display mode and a first sub-scene of said two-dimensional scene in said second display mode, said first sub-scene being an enlarged view of a portion of said two-dimensional scene, said first sub-scene being characterized by a sub-scene position within said two-dimensional scene, said display screen further displaying a cursor that moves within said first sub-scene in a manner controlled by said position of said puck when said puck is in said pointing region in said second display mode,wherein said controller causes said display screen to change from said second display mode to said first display mode when said puck enters said function region to switch from displaying said first sub-scene on said display screen to displaying said two-dimensional scene on said display screen and wherein said controller causes said display screen to change from said first display mode to said second display mode when said puck returns to said pointing region to switch from displaying said two-dimensional scene on said display screen to displaying said first sub-scene on said display screen.

Abstract
A display device having a puck, a display screen, and a controller is disclosed. The puck moves in a puck field of motion on a surface, the field of motion being divided into a pointing region and a function region. The controller determines a position of the puck within the field of motion. The display screen has first and second display modes, the display screen displaying a two-dimensional scene in the first display mode and a sub-scene of the two-dimensional scene in the second display mode. A cursor that moves within the sub-scene in a manner controlled by the puck position in the pointing region is displayed in the second mode. The controller causes the display scene to change between modes when the puck moves between regions. The sub-scene position moves in response to the position of the puck in the function region in the first display mode.

1. A display 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, said puck being characterized by a position within said field of motion; a controller that determines a position of said puck within said field of motion; and a display screen having first and second display modes, said display screen displaying a two-dimensional scene in said first display mode and a first sub-scene of said two-dimensional scene in said second display mode, said first sub-scene being an enlarged view of a portion of said two-dimensional scene, said first sub-scene being characterized by a sub-scene position within said two-dimensional scene, said display screen further displaying a cursor that moves within said first sub-scene in a manner controlled by said position of said puck when said puck is in said pointing region in said second display mode, wherein said controller causes said display screen to change from said second display mode to said first display mode when said puck enters said function region to switch from displaying said first sub-scene on said display screen to displaying said two-dimensional scene on said display screen and wherein said controller causes said display screen to change from said first display mode to said second display mode when said puck returns to said pointing region to switch from displaying said two-dimensional scene on said display screen to displaying said first sub-scene on said display screen. - View Dependent Claims (2, 3, 4, 5, 6, 7)

8. A method for inputting data to a device having a display screen thereon, said method comprising:
-
providing a moveable puck that moves within a field of motion on a surface, said puck being characterized by a position within said field of motion; dividing said field of motion into a pointing region and a function region; providing a moveable puck confined to move on said first surface; displaying a first two-dimensional scene on said display screen when said puck is in said pointing region and a second two-dimensional scene when said puck is in said function region, said first two-dimensional scene being a first sub-scene within said second two-dimensional scene characterized by a sub-scene position, said first two-dimensional scene being an enlarged view of a portion of said second two-dimensional scene; switching from displaying said first sub-scene on said display screen to displaying said second two-dimensional scene on said display screen when said puck enters said function region; and switching from displaying said second two-dimensional scene on said display screen to displaying said first sub-scene on said display screen when said puck returns to said pointing region. - View Dependent Claims (9, 10, 11, 12, 13)
