Method, system and device for augmented reality

摘要

A portable electronic device comprises augmented reality viewing apparatus for viewing a real scene and a superimposed computer generated overlay scene. In one embodiment the viewing apparatus comprises a display screen (2) and a semitransparent mirror (3). The semitransparent mirror (3) is pivotally mounted on the device and may be rotated between a position for viewing augmented reality and a position for viewing a displayed image alone. In another embodiment the real scene is viewed through a transparent display screen. When viewing augmented reality, the user aligns the overlay scene with the real scene by means of an alignment indicator (13,15, not shown in FIG. 5) in the overlay scene which corresponds to a predetermined element of the real scene. The device may be equipped with location determining means (50), the selection of a displayed image thereby being dependent on the location of the device, whether the images for display are stored locally in the device or transmitted by radio from a remote server. The device may also be equipped with an orientation sensor so that the selection of a displayed images is dependent on orientation of the device.
