research directions -- augmented reality
In the theatre production that motivated the development of the ViP system,
the idea was to have wearable LCD-projection glasses, with a head-mounted low resolution camera.
This setup is common in
augmented reality applications,
where for example a historic site is enriched with graphics and text,
laid on top of the (video rendered) view of the site.
Since realtime image analysis is generally not feasible,
either positioning and orientation information must be used,
or simplified markers indicating the significant spots in the scene,
to determine what information to use as an overlay and how it should be displayed.
The ARToolkit is an advanced, freely available,
toolkit, that uses fast marker recognition to determine the viewpoint
of a spectator.
The information that is returned on the recognition of a marker
includes both position and orientation,
which may be used by the application to draw the overlay graphics
in accordance with the spectator's viewpoint.
Augnented reality is likely to become a hot thing.
In april 2005 it was featured at
BBC World, with a tour through Basel.
