Karen Marcelo (left) of Survival Research Labs, Eric Paulos of Intel Research Laboratory (center) and Anthony Burke of the University of California at Berkeley's architecture department (right) created this RFID demonstration. Another member of the project, Berkeley lecturer David Ross, is not pictured.
Visitors of the MoMA's reception on Thursday evening were given a RFID tag to wear. Each tag was implanted with a unique number that could be tracked when it came within range of one of the RFID tag readers.
This output from the RFID tag reader, compiled by a Java program, was beamed on a screen and updated every minute. Each vertical column indicates a separate RFID tag. The colors show where in the room the tag was read. Newer arrivals are to the right, and black means that the person left the reception.
