Responsive Body Tracking	an interactive installation by Michael Hoch, in collaboration with Daniel Thalmann, Soraia Raupp Musse, Fabien Garat
	this installation deals with interface paradigms between real users in real space and virtual groups and crowds. The visitor can explore different modes of group modalities of interaction and differing linkage between real and virtual crowds. Based on events in real space, that get recognized using a vision system, corresponding events in virtual space are triggered. Our findings give some insight in the social and artistic perspective of the approach.
Group Interaction	an interactive installation Michael Hoch and Detlev Schwabe shown at ZKM, Germany '99.
	we experiment on the general notion that people are necessarily aware of their (local) position in group situations and they experience the physical space and the social climate of a group situation by simultaneously watching and moving around. Vision tracking hardware and software technology has been applied on a situation in a dome projection system where 5 persons interact with the projected imagery of a virtual deep-sea world in which schools of marine life forms roam the grounds. The interface software relates the persons movement behaviour to the flock of fish in terms of attraction, avoidance, fleeing, and following.
in/outSide	an interactive installation by Ursula Damm and Michael Hoch shown at Ars Electronica '98, ArtCologne '97, and Media Formum NRW '98.
	This project deals with the discrepancy between an individual's surroundings in everyday life and the internal "spaces" which he/she images and lives out. The installation observes the movements of human beings in public places and their interactions during spantaneous encounters. Geometric interpretations analyze spatial relationships. An overhead camera registers the paths along which human beings move and which, thus, provide information on the utilization of the particular site.
VbodyRbody	an interactive installation by Akke Wagenaar, Masahiro Miwa, Michael Hoch and Matthias Melcher
	The viewer stands in front of a large back projection screen showing an image of a virtual human form. When the viewer starts to move, he-she causes the virtual form to unfold itself slowly into a position which is mirroring the position of the viewer. The virtual form continuously collapses into a state of terrible physical destortion if the viewer stops moving. The interface human-machine consists of an infrared camera which monitors anybody in front of the projection screen.
Simulation Room - Mosaic of Mobile Sound Data	an interactive installation in collaboration with knowbotic research, shown at "Mediale" '93 in Hamburg, Ars Electronica '93, Interactive Media Festival, Los Angeles '94, SIGGRAPH '94, Exploratorium San Francisco '95, ARTEC '95 Nagoya
	virtual reality project with a sophisticated, walk-in database, utilising a collection of self-organizing sound samples from around the world. sounds are used to produce a virtual sound room. the visitor is able to navigate through the sound space with the aid of a mobile ultrasonic sensor and an artificial eye display. These allow the visitor to orientate and to activate the sounds to a real time concert.
Dialogue With The Knowbotic South	an interactive installation in collaboration with knowbotic research shown at Ars Electronica '94:
	A computer model of the Antarctica is devised as a public knowledge space, providing a form of interaction with multilocal and multipresent information-fields. The structure-imposing units in this hypothetical area are knowbots that incorporate data sets of current antarctic research, which symbolize direct real-time links to the reference subjects occurring in scientific research. A spatial interactive feature allows the user to 'immerse' himself into each knowbot.
