Wireless sensors the Lego way
Todd Winkler, a professor at Brown University in Rhode Island, and Mikael Fernstrom, a lecturer at the University of Limerick in Ireland, have choreographed performance pieces in which the dancers are rigged up with small wireless sensors that can alter the music and the images on screens. When the dancers move, changes occur in response. In other words, it’s an arty version of the Wii.
It’s one of the more novel applications for a Lego-like sensor platform developed by Brendan O’Flynn, who works in the Ambient Electronic Systems Integration group at the Tyndall National Institute here. The sensors are similar to wireless motes from companies like Dust Networks and Crossbow Technology. The difference lies in the ability to mix and match the components and capabilities of any given sensor, he says.
