Patent Images
1. A computer-implemented method comprising:
- capturing, by a handheld device, a camera image of one or more fiducials rendered by a display device;
determining a position or an angle of the one or more fiducials in the captured camera image;
determining a position on the display device that the handheld device is aimed towards based at least on the determined position or angle of the one or more fiducials in the camera image; and
controlling an application based on the determined position on the display device.

Abstract
Enhanced handheld screen-sensing pointing, in which a handheld device captures a camera image of one or more fiducials rendered by a display device, and a position or an angle of the one or more fiducials in the captured camera image is determined. A position on the display device that the handheld device is aimed towards is determined based at least on the determined position or angle of the one or more fiducials in the camera image, and an application is controlled based on the determined position on the display device.
