1. A method of comprising the steps:
- sensing a pointer spaced apart from a display screen of a touch-enabled device as the pointer approaches the display screen;
determining a 3-dimensional trajectory of the pointer in space;
determining a pointer type;
designating a target object on the display screen based upon the determined pointer type and the determined 3-dimensional trajectory while the pointer is spaced apart from the display screen, wherein certain objects are not eligible to be designated as the target object based on the pointer type; and
modifying an appearance of the designated target object on the display screen.

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.

1. A method of comprising the steps:
-
sensing a pointer spaced apart from a display screen of a touch-enabled device as the pointer approaches the display screen; determining a 3-dimensional trajectory of the pointer in space; determining a pointer type; designating a target object on the display screen based upon the determined pointer type and the determined 3-dimensional trajectory while the pointer is spaced apart from the display screen, wherein certain objects are not eligible to be designated as the target object based on the pointer type; and modifying an appearance of the designated target object on the display screen. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10)

11. A system comprising:
-
a processor; a memory; an input trajectory element configured to determine a 3-dimensional trajectory of a pointer when the pointer is spaced apart from a display screen of a touch-enabled device, based upon detected 3-dimensional positioning of the pointer over time; a pointer type determination element configured to determine a type for the pointer; and a predictor/adapter configured to provide a display control signal modifying an appearance of the display screen of the touch-enabled device based upon the determined 3-dimensional trajectory of the pointer, wherein the predictor/adapter is further configured to designate a target object on the display screen based upon the determined 3-dimensional trajectory and the determined pointer type, wherein certain objects are not eligible to be designated as the designated target object based on the determined pointer type, and wherein the predictor/adapter is further configured to provide another control signal for changing an appearance of the designated target object on the display screen. - View Dependent Claims (12)

13. A method comprising the steps of:
-
sensing a pointer when the pointer is spaced apart from a display screen of a touch-enabled device; determining a position of the pointer in 3-dimensional space over time; computing a 3-dimensional trajectory of the pointer based upon the determined position over time; modifying an appearance of the display screen based upon the 3-dimensional trajectory; determining a pointer type for the pointer; designating a target object on the display screen based upon the computed 3-dimensional trajectory and the determined pointer type, wherein certain objects are not eligible to be designated as the target object based on the pointer type; and modifying an appearance of the designated target object on the display screen. - View Dependent Claims (14)
