Mobile device with wide range-angle optics and a radiation sensor
First Claim
1. A method for using a handheld device for controlling content displayed on an electronic display, said mobile device including wide-angle optics and an image sensor for capturing images, the method comprising the steps of:
- capturing at least two images at said image sensor through the wide-angle optics including a first image indicating a first position of the mobile device at a first point in time, and a second image indicating a second position of the mobile device at a second point in time;
calculating a change between said first position and said second position of the mobile device by analyzing differential motion of a feature common to both the first image and the second image; and
;
altering content displayed on an electronic display in accordance with the calculated change.

Abstract
The invention comprises a mobile device controlled by moving it, for example, by tilting. The mobile device 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 mobile device. 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 of the mobile device is altered. The content is, for example, a menu or a web page.

7. 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 image sensor integral to said handheld device through wide-field optics and storing said first image in a memory; acquiring a second image at said digital image sensor through said wide-field optics 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. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)
