I co-developed an interactive table for sound mapping tea houses across London. Through mapping field recordings project investigates social and geographical landscape of contemporary tea drinking culture in London. The interactive tea table covered with a map of London activates a recording from a teahouse in each of the thirty-three London boroughs. A teapot marked with an infrared LED allows it to be tracked by a computer vision system. As the teapot is moved around the map, the vision system recognises which borough of London it has been placed on and plays the related tea house soundscape. G.Hack presented Sound Mapping London Tea Houses as participating artists in the Chi-TEK project.
