Big brother buildings offer less invasive security

From a story at New Scientist
Tracking people's every move using buildings packed with motion sensors is more effective than CCTV, and less invasive to privacy, say researchers who tried the technique on their own colleagues.
Two researchers used arrays of small, cheap motion detectors to watch over people instead, with their officemates as guinea pigs. They fitted their 3000 square metre office building with an array of 215 simple detectors placed along the hallways at 2-metre intervals.
Most techniques for analysing data from sensor networks depend on automatically detecting certain behaviours specified ahead of time, making spotting unexpected features difficult, he says.
This reminds me of my project Lacuna created several years ago now that tracked exactly this sort of thing for artistic purposes, rather than for surveillance.
Lacuna is an ongoing project that receives live data streams from an electronic skin of architecture at the University of Plymouth’s Portland Square building. The data is then transformed into a 3D virtual reality dataspace, allowing people to step inside a virtual construction. However, as the occupants of the building turn on lights, open windows, use computers or even flush the toilet they change and control the animations on screen.
