Mobile device with wide-angle optics and a radiation sensor
First Claim
1. A mobile device comprising:
- a memory,a processor,a display for showing content,wide-angle optics, anda navigation chip having a radiation sensor for detecting positions of the mobile device, the wide angle optics being disposed in front of the navigation chip and configured such that the navigation chip receives, through the wide angle optics, radiation from a large area outside of the mobile device,the mobile device being adapted to receive at least first and second images through the wide-angle lens and the navigation chip, wherein the first image indicates a first position of the mobile device at a first point in time and the second image indicates a second position of the mobile device at a second point in time, to store the first and second images as sets of luminosity values in the memory, to determine a change between the first position and the second position of the mobile device by applying a motion detection method to the first image and the second image, and to alter the content shown on the display in accordance with the determined change,wherein the motion detection method comprises superimposing the first image and the second image, calculating a best-fit offset between the first image and the second image, and calculating the change on the basis of the best-fit offset.

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.

10. A mobile device comprising:
-
a memory, a processor, a display for showing content, wide-angle optics, and a navigation chip having a radiation sensor for detecting positions of the mobile device, the mobile device being adapted to receive at least first and second images through the wide-angle lens and the navigation chip, wherein the first image indicates a first position of the mobile device at a first point in time and the second image indicates a second position of the mobile device at a second point in time, to store the first and second images as sets of luminosity values in the memory, to determine a change between the first position and the second position of the mobile device by applying a motion detection method comprising superimposing the first image and the second image, calculating a best-fit offset between the first image and the second image, and calculating the change on the basis of the best-fit offset, the mobile device being configured to alter the content of the display as follows; when the mobile device determines, by the motion detection method, a single change between the first position and the second position, the mobile device alters the content of the display by moving a cursor in accordance with the single change, and when the mobile device determines, by the motion detection method, two successive changes in position including first and second changes in position of the mobile device, wherein the first change meets a first predetermined criterion at a third point in time and the second change meets a second predetermined criterion within a predetermined time period starting from the third point in time, the mobile device alters the content of the display by performing one of zooming in the content, zooming out the content, closing a menu, opening a menu, and selecting a menu option.

11. A mobile device comprising:
-
a memory, a processor, a display for showing content, wide-angle optics, and a navigation chip having a radiation sensor for detecting positions of the mobile device, the mobile device being adapted to receive at least first and second images through the wide-angle lens and the navigation chip, wherein the first image indicates a first position of the mobile device at a first point in time and the second image indicates a second position of the mobile device at a second point in time, to store the first and second images as sets of luminosity values in the memory, to determine a change between the first position and the second position of the mobile device by applying a motion detection method comprising superimposing the first image and the second image, calculating a best-fit offset between the first image and the second image, and calculating the change on the basis of the best-fit offset, the mobile device being configured to alter the content of the display as follows; when the mobile device is moved from the first position to the second position, the mobile device determines, by the motion detection method, a first change and alters a first content on the display to a second content, and when the mobile device is moved from the second position back to the first position, the mobile device determines, by the motion detection method, a second change and alters the second content on the display back to the first content.
