combines the text input of Internet users with the physical movement
of museum goers to create an animated luminous display of text projected
on the wall. On the Point-to-Point web site (http://potatoland.org/point),
users input their answer to the question, "Who are you?" then use their
mouse to draw the answer on the screen. In the museum, a surveillance
camera detects the presence of viewers in front of the artwork, and
software translates their movement into trails of text on the wall.
artwork becomes a window through which visitors online and in the museum
can see the actions on the 'other side' as they happen. The artwork
uses a surveillance camera to watch the space in front of the artwork
in the museum.
vision tracking software detects the presence of people in the space,
and turns their movements into screen coordinates. These coordinates
are transmitted over the web to a modified chat server that relays people's
movements to anyone viewing the "Point-to-Point" applet at that time.
The vision software, "CMVision", is used in robotics projects and was
developed by James Bruce at Carnegie Mellon University.
