1. A touch screen device comprising:
- a touch screen including a plurality of sensors arranged in X and Y coordinates defining a touch display area and configured to detect touch inputs;
a housing, at least a portion of the touch screen being incorporated as part of a front surface of the housing, the housing having a back surface opposite the front surface, and a side surface extending between the front surface and the back surface;
a strip sensor at an edge or border of the touch screen device extending longitudinally along and outside the touch display area, the strip sensor configured to sense a user'"'"'s hand gripping the touch screen device at the edge or border, and output information regarding a location of the user'"'"'s hand on the strip sensor; and
a processor configured to;
map a contour of an area of the touch display area receiving touch inputs and adjacent the location of the user'"'"'s hand on the strip sensor by at least;
receiving, from the plurality of sensors, touch point data corresponding to a region of the touch display area that is in contact with a part of the user'"'"'s hand;
determining, from the touch point data, a shape and a perimeter of the region of the touch display area that is in contact with the part of the user'"'"'s hand; and
using the determined shape and perimeter of the region as the contour of the area of the touch display area;
determine that the area of the touch display area is within a predetermined distance from the edge or border of the touch screen device and on a same side as the location of the user'"'"'s hand; and
ignore active touch inputs received within the area of the touch display area that are within the predetermined distance and while the user'"'"'s hand continues to be sensed using the strip sensor.

Abstract
A touch-screen device and method for operating a touch-screen device are provided herein. The touch device comprises sensors around the edge and/or on the back of the device that will determine where a user is holding the device. Based on this information certain areas of the touch screen will be ignored or inactivated. This allows the device to selectively ignore the touch of the thumb and or palm.

12. A method comprising:
-
determining a location of a hand of a user gripping a device via an elongated strip sensor that is separate from a touch screen defined by a plurality of sensors in X and Y coordinates defining a display area within a boundary of the touch screen, the strip sensor being adapted for sensing in an area outside of the boundary of the touch screen, the device including a housing having at least a portion of the touch screen incorporated as part of a front surface of the housing, the housing additionally having a back surface opposite the front surface and one or more side surfaces extending between the front surface and the back surface; mapping a contour of a plurality of active inputs within the boundary of the touch screen by at least; receiving, from the plurality of sensors, touch point data corresponding to a region of the touch screen that is in contact with a part of the hand of the user; determining, from the touch point data, a shape and a perimeter of the region of the touch screen that is in contact with the part of the hand of the user; and using the determined shape and perimeter of the region as the contour of the plurality of active inputs; determining that the contour of the plurality of active inputs is within a predetermined distance from the boundary of the touch screen and on a same side as the location of the hand of the user; and determining that the mapped plurality of active inputs within the boundary of the touch screen are to be ignored based on; the location of the hand of the user continuing to be determined, using the strip sensor; and the mapped plurality of active inputs within the boundary of the touch screen being within the predetermined distance. - View Dependent Claims (13, 14, 15, 16, 17)

18. A method in a device having a housing with at least a portion of a touch screen incorporated at a front surface of the housing, the housing additionally having a back surface opposite the front surface, and one or more side surfaces extending between the front surface and the back surface, the method comprising:
-
determining a location of a hand of a user gripping the device via an elongated strip sensor, separate from the touch screen including a plurality of touch-display elements arranged according to X and Y coordinates, the strip sensor being adapted for sensing in an area outside of a boundary of the touch screen; and mapping a contour of an area of active inputs on the touch screen within the boundary of the touch screen by at least; receiving, from the plurality of touch-display elements, touch point data corresponding to a region of the touch screen that is in contact with a part of the hand of the user; determining, from the touch point data, a shape and a perimeter of the region of the touch screen that is in contact with the part of the hand of the user; and using the determined shape and perimeter of the region as the contour of the area of active inputs; determining that the contour of the area of active inputs is within a predetermined distance from the boundary of the touch screen and on a same side as the location of the hand of the user; and ignoring the mapped area of active inputs when the mapped inputs are within a predetermined distance from a same side surface of the housing of the device as the sensed location of the hand of the user. - View Dependent Claims (19, 20)
