We also went to the opening of the ISEA exhibition last nite in South Hall. Walking around town, we noticed some cement bricks attached to light posts and stop lights around the city. The project, “Loca” by Drew Hemment, Mika Raento, John Evans, and Theo Humphries “deploys a cluster of interconnected Bluetooth nodes within inner city urban environments; each node is built using readily available, cheap parts and is encased in concrete. Loca can track any Bluetooth device that the owner has set to visible. Our system makes inferences based on analysis of the collected data to guide communication with these Bluetooth users, for example via unsolicited messages or performers.” A simple, but effective way of tracking the movement of people carrying moble devices around a city.
