US Patent 7379566: Optical flow based tilt sensor
US 7379566 ยท granted 2008-05-27
Abstract
A method is described for determining a description of motion of a moving mobile camera to determine a user input to an application. The method may involve capturing a series of images from a moving mobile camera and comparing stationary features present in the series of images. Optical flow analysis may be performed on the series of images to determine a description of motion of the moving mobile camera. Based on the determined motion, a user input to an application may be determined and the application may respond to the user input, for example, by updating a user interface of the application.

Claim 1
A method comprising: capturing images from a moving mobile camera; determining a description of motion of the moving mobile camera based on the captured images; rendering a user interface for an application on an interface device, the user interface including an object; and controlling, in an automated manner, movement of the object rendered in the user interface in a manner corresponding to the determinedmotion of the moving mobile camera, wherein controlling, in an automated manner, movement of the object rendered in the user interface in a manner corresponding to the determined motion of the moving mobile camera further comprises replicating a tiltsensor function to control a tilt of the object rendered in the user interface.
