1. A method of modifying a display on a touch-enabled device comprising the steps of:
- sensing a pointer spaced apart from the display as the pointer approaches the display;
determining a 3-dimensional trajectory of the pointer in space;
designating a target object on the display based upon the determined trajectory while the pointer is spaced apart from the display; and
modifying an appearance of the designated target object.

Abstract
Apparatus and methods for improving touch-screen interface usability and accuracy by determining the trajectory of a pointer as it approaches the touch-screen and modifying the touch-screen display accordingly. The system may predict an object on the display the user is likely to select next. The system may designate this object as a Designated Target Object, or DTO. The system may modify the appearance of the DTO by, for example, changing the size of the DTO, or by changing its shape, style, coloring, perspective, positioning, etc.

13. A system for modifying a display on a touch-enabled device configured to accept input from a pointer comprising:
-
an input trajectory element configured to determine a 3-dimensional trajectory of the pointer when the pointer is spaced apart from the touch-enabled device display, based upon a detected 3-dimensional position of the pointer over time; and a predictor/adapter configured to provide a display control signal modifying an appearance of the display on the touch-enabled device based upon the determined trajectory of the pointer. - View Dependent Claims (14, 15, 16)

17. A method of modifying a display on a touch-enabled device comprising the steps of:
-
sensing a pointer when it is spaced apart from the touch-enabled device display; determining a position of the pointer in 3-d space over time; computing a 3-dimensional trajectory of the pointer based upon the determined position over time; and modifying an appearance of the touch-enabled device display based upon the 3-dimensional trajectory. - View Dependent Claims (18, 19, 20)
