Mobile device with wide-angle optics and a radiation sensor
First Claim
1. A method for using a handheld device for controlling content displayed on an electronic display, comprising the steps of:
- acquiring a first image at a digital imager integral to said handheld device through a wide-angle lens and storing said first image in a memory;
acquiring a second image at said digital imager through said wide-angle lens and storing said second image in said memory;
analyzing said first image to resolve an image feature contained in said first image;
analyzing said second image to resolve said image feature also contained in said second image;
calculating an offset distance between said image feature in said first image to said image feature in said second image;
altering content displayed on said electronic display in accordance with said calculated offset distance.

Abstract
A method and device for displaying content using an integral or remote controller for navigating the content based on dynamic image analysis of the motion of the controller, for example, by tilting. The controller is equipped with wide-angle optics and with a radiation sensor detecting either visible light or infrared radiation. The wide-angle optics may be directed towards the user, whereupon the radiation sensor receives useful images through the wide-angle optics. The images include contrast or thermal differences which it make possible to determine in which way the user has moved the controller. In more detail, a tilt angle or a corresponding change can be calculated and then, on the basis of the change, the content shown on a display is altered. The content is, for example, a menu, game scene or a web page.
