Tracking and displaying the paths of visitors
The system displays the aggregate paths of the last two hundred visitors along with blobs representing the people currently being tracked. When viewers approach the work, they can display the live video image with the paths of currently tracked visitors superimposed. (...) The technology of this system is rooted in surveillance systems that are rapidly being put into place in all of our public spaces: airports, shopping malls, grocery stores and our streets and parks. The motivation for such public systems ranges from security and law enforcement to marketing and advertising. The system of this artwork is wholly anonymous – no data is collected and the only use of the information is by the museum visitors to track themselves and their friends. However, in many real-world applications of such technology, the identities of those being tracked are also registered. You Are Here provides a visceral understanding of surveillance systems' capabilities and a sensual, visual representation of information that is normally only accessible as dry statistics.
This benevolent application of tracking is also meant to show the interconnectedness of viewers' with other visitors to the space by give them a sense of the aggregate presence of people over time.
Why do I blog this? it's an interesting art piece that address the issue of spatial data, food for thoughts for our replay tool project.
