Object_State (Matt Adair and Harrie Pearce) have been playing around with motion capture generated visuals since 2005. For VJ-ing we utilise a combination of Resolume, Eyesweb and an infra-red camera to create colourful feedback loops of on-stage performers and abstract shapes.
Our website has some information about what we do: Object_State
The Clan Youtube channel has some examples of our performances during Gear Shift 2014, with a highlighted one here taken during Zen Paradox’s set: youtube link
Currently we are investigating development of Eyesweb plugins using their SDK with the occasional peek into OpenCV and Intel’s Integrated Performance Primitives.
