technical realization
The information contained in the data packages
is retrieved by means of the bar code and a decoder. The data will be projected
on the walls of the bubbles.
Data Packet
Each data packet has a bar code. We all know this kind of encoded information
from the supermarket. The scanner reads the code by means of a light beam.
Since it is widely used nowadays, the technology is priceworthy and easy
to handle.
Video Projection
The information accessible to the visitors depending on their individual
bar codes is gathered from WWW pages referring to the subject in question.
Since the theater line will be quite busy during the experiment, the data
will be information from a pre-downloaded page in the bubble. (These pages
can be quickly retrieved from a clip board to avoid excessive time spans
for downloading.) The data will then be projected on the interior walls
of the bubbles. This is accomplished either by special overhead displays,
which are connected to the computer, or by so-called video beams (devices,
which project a computer image on a screen).
