Stabilized image projecting device
First Claim
1. A mobile device adapted to optically project at least a first image and a pointer pattern on an external surface, said mobile device comprising at least:
- a sensor to provide movement information related to angular movement of said mobile device with respect to an external reference, and a control unit to move the position of said first image with respect to said pointer pattern according to said movement information such that the relative movement of said first image with respect to said external reference is substantially smaller than the relative movement of said pointer pattern with respect to said external reference.

Abstract
A handheld projecting device is adapted to project an image and a pointer pattern on an external surface. The projecting device comprises a sensor to detect the movements of the projecting device and means to dampen the movements of the projected image, based on the detected movements of the projecting device. When the handheld projecting device is turned, the position of the projected image is kept substantially stationary whereas the pointer pattern moves on the projected image to indicate a point of the projected image. In an embodiment, the pointer pattern may be used to make a selection between graphically displayed options.
