In one embodiment of the invention, a hot spot is normally centered in an area of contact between a user's finger and a touch screen to position the hot spot on an icon or other feature thereby selecting a program or function corresponding to the icon or feature. When the contact area is near an edge, the hot spot is offset toward the edge so that it coincides more closely to the center of the users finger, thus allowing an icon or other feature adjacent the edge of the screen to be more easily selected. In another embodiment, a cursor is displayed on a touch screen at a location that is offset from the contact area between a finger and the screen. The cursor, which is used as the hot spot of the computer, is normally offset above the contact area except when the contact area is close to the bottom of the screen. The cursor is then offset to the left or right of the contact area depending on whether the contact are is to the left or right of the screen, respectively, so that icons or features adjacent the left or right edges of the screen can be selected. Similarly, when the contact area is very close to the bottom of the screen, the cursor is offset downwardly and to the right or left so that icons or features adjacent the bottom edge of the screen can be selected. Alternatively, a touch sensitive area incapable of displaying an image may be provided beneath a display area of the touch screen to allow icons or features adjacent the bottom edge of the display area to be selected.

What is claimed is: 1. A computer, comprising: a processor; a memory device coupled to the processor, the memory device storing software instructions for execution by the processor; a touch screen constructed to display information corresponding to input data signals and to provide data signals corresponding to a user input; a touch screen driver coupled to the processor and to the touch screen, the touch screen driver being constructed to determine a position of a contact area on the touch screen, and, if the contact area is at a first location on the touch screen, registering the user input at a first position that is offset relative to the contact area, and, if the contact area is at a second location on the touch screen that is different from the first location, registering the user input at a second position that is not offset relative to the contact area. 2. The computer of claim 1 wherein the first location is within a predetermined distance of an edge of the touch screen. 3. The computer of claim 2 wherein the touch screen driver is constructed to register the user input at the first position relative to the contact area by selecting a position for the first position that is closer to the edge than the second position. 4. The computer of claim 1 wherein the touch screen has a top edge, a bottom edge, a left edge, and a right edge, and wherein the first location is within a predetermined distance of either the top edge, the bottom edge, the left edge, or the right edge of the touch screen. 5. The computer of claim 4 wherein the touch screen driver is constructed to register the user input at the first position relative to the contact area by selecting a position for the first position that is closer than the second position to the edge to which the contact area is located within the predetermined distance. 6. The computer of claim 1 wherein the first location is within a predetermined distance of any edge of the touch screen, the second location comprises all locations on the touch screen not constituting the first location, the first and second positions are within the contact area, and the first position is offset from the second position toward the edge that the contact area is located within the predetermined distance. 7. The computer of claim 1 wherein the first location is within a predetermined distance of an edge of the touch screen, the first position is offset from the contact area in a first direction, and the second position is offset from the contact area toward the edge that the contact area is located within the predetermined distance. 8. The computer of claim 7 wherein the first direction is above the contact area. 9. The computer of claim 1 wherein the touch screen driver is constructed to cause the display to display a cursor at the first position if the contact area is at the first location on the touch screen, and to display a cursor at the second position if the contact area is at the second location on the touch screen. 10. The computer of claim 1 wherein the touch screen comprises: a touch sensitive display area constructed to display information corresponding to the input data signals and to provide data signals corresponding to the user input; and a touch sensitive area positioned adjacent the display area constructed to be unable to display information and constructed to provide data signals corresponding to the user input. 11. The computer of claim 10 wherein the touch sensitive area of the touch screen is positioned below the display area of the touch screen. 12. The computer of claim 1 wherein the touch screen driver is constructed to register the user input at a position relative to the contact area that is to the left of the contact area if the contact area is on the left side of the touch screen, and to register the user input at a position relative to the contact area that is to the right of the contact area if the contact area is on the right side of the touch screen. 13. The computer of claim 1 wherein the touch screen driver is constructed to register the user input at a position relative to the contact area that is downwardly to the left of the contact area if the contact area is within a predetermined distance of a bottom edge of the touch screen on the left side of the touch screen, and to register the user input at a position relative to the contact area that is to the right of the contact area if the contact area is within a predetermined distance of a bottom edge of the touch screen on the right side of the touch screen. 14. The computer of claim 1 wherein the touch screen driver is constructed to register the user input at a position relative to the contact area that is above the contact area. 15. The computer of claim 1 wherein the touch screen driver is constructed to register the user input at a position relative to the contact area that is to the left of the contact area if the contact area is on the left side of the touch screen and the contact area is not moving to the right past a location where the registered user input is on the right side of the touch screen, and to register the user input at a position relative to the contact area that is to the right of the contact area if the contact area is on the right side of the touch screen and the contact area is not moving to the left past a location where the registered user input is on the left side of the touch screen.
