Prosthetic Head, 2003, Interactive installation

About the work

The Prosthetic Head is an embodied conversational agent (ECA) that speaks to the person who interrogates it. It is projected 5 m in height in its own light-trapped space. The cuboid space becomes the ďhead-spaceĒ of the Prosthetic Head. A sensor system alerts it that someone is present. The Prosthetic Head turns, opens its eyes and initiates the conversation. The interface is a keyboard and the text box beneath the 5 m high projected head confirms the userís query. Exactly how you ask the question will determine the Prosthetic Headís response. So thereís a translation between the keyed in text and the text-to-speech engine that coupled to the geometry and animation of the 3D model results in the real-time lip synching and spoken response. The effectiveness and seductiveness of the ECA is that it needs to be somewhat convincing in both itís comprehension and communication with the user.It is now possible to code both verbal and facial responses to the userís queries. The Prosthetic Head, with its facial behaviour and basic repertoire of expressed emotion performs with words. The Prosthetic Head then is a conversational system, that coupled to a human user is capable of some interesting, often appropriate and at times unpredictable exchanges. The Prosthetic Head can generate its own poetry and song-like sounds which are different each time it is asked. The system now is capable of head-tracking, so that the Prosthetic Head can locate you in the space and follow you around. Additional capabilities will be color detection and even face recognition which will result in more personal exchanges and remarks about the appearance of the user. And as its data base increases and its feedback from the real world increases the artist will no longer be able to take full responsibility for what his Head says.

Stelarc is a performance artist who has visually probed and acoustically amplified his body. He has made 3 films of the inside of his body. Between 1976-1988 he completed 25 body suspension performances with hooks into the skin.

His FRACTAL FLESH, PING BODY and PARASITE performances explored involuntary, remote and Internet choreography of the body with electrical stimulation of the muscles.
