Patent ID: 8884928

Claim:
A computer-implemented method of correcting for parallax errors in a touch screen of a computing device, comprising: capturing image information using a camera of the computing device; analyzing the image information, using a processor of the computing device, to track a relative position of a head of a user with respect to the computing device; and for a current relative position of the head: determining, using the processor of the computing device, an amount of offset between a first region and a second region of a touch sensitive surface of the touch screen, wherein the first region is mapped by the computing device to a graphical element displayed on a display surface of the touch screen and the second region corresponds to a viewed position, from the current relative position of the head, of the graphical element at the touch sensitive surface; updating a mapping of the graphical element from the first region to approximately the second region on the touch sensitive surface when the amount of offset exceeds an offset threshold, wherein the user is able to select the graphical element using the second region of the touch sensitive surface; and updating a displayed location of the graphical element such that the viewed position of the graphical element through the touch sensitive surface corresponds to the first region in response to determining that the amount of offset is greater than a maximum amount of acceptable offset but less than the offset threshold, wherein the user is able to select the graphical element using the first region of the touch sensitive surface.
