Don't touch that! Keep your hands off!
This is what you often hear parents shouting at their children
in a museum or gallery exhibit.
More often, however, precious artifacts,
ceramics, porcelain or bronzes,
are stored away in glass showcases, precluding any kind
of physical interaction,
and many times a proper look as well.
To remedy this situation, researchers from
the Academia Sinica and the National Cheng Kung University
have developed a
tangible photorealistic virtual museum,
a system for real-time interaction with photorealistic museum
artifacts, which allows for an immersive experience
using tangible interfaces, in the form of a 3D control cube
(image left),
[Tangible].
The display is a kiosk-like system showing a panoramic
view of the exhibit, augmented with a
collection of perspective photographs for each object.
The user may examine any of the objects
by using a handheld control cube (PCC)
to control size and rotation of the object.
As indicated, the system is not 3D mesh-based but image-based,
which allows for high resolutions on mid-range
platforms, which would not be feasible according to the authors,
when using 3D modelling techniques.
