MONITORING POINTER TRAJECTORY AND MODIFYING DISPLAY INTERFACE
First Claim
Patent Images
1. A method, comprising:
- sensing a pointer spaced apart from a touch-enabled display of a computing device as the pointer approaches the touch-enabled display;
determining a 3-dimensional trajectory of the pointer relative to the touch-enabled display;
designating a target object on the touch-enabled display based upon the determined 3-dimensional trajectory while the pointer is spaced apart from the touch-enabled display; and
modifying an appearance of the designated target object on the touch-enabled display.

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.

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 touch-enabled display of a computing device, based upon detected 3-dimensional positioning of the pointer over time; and
,a predictor/adapter configured to designate a target object on the touch-enabled display based upon the determined 3-dimensional trajectory and further configured to provide a control signal for changing an appearance of the designated target object on the touch-enabled display. - View Dependent Claims (12, 13)

14. A method, comprising:
-
sensing x, y, and z coordinates of a pointer over time; computing a 3-dimensional trajectory of the pointer relative to a touch-enabled display of a touch enabled device based upon the x, y, and z coordinates; designating a target object on the touch-enabled display of the touch enabled device based upon the computed 3-dimensional trajectory of the pointer; and
,modifying an appearance of the target object on the touch-enabled display. - View Dependent Claims (15)
