Within the interactive media, there are two basic modi for exerting influence: conscious navigation and bio-feed-back. While the firstmentioned describes a precise process of interaction, within which one travels from decision to decision, bio-feedback describes a nonconscious steering, dependent on physical conditions. affectiveCinema is controlled by bio-feedback. Specifically, it is the affective reaction of the human being on being confronted with a virtual person. Once the visitor has taken his seat in the installation, the person shown on the monitor screen opposite wakes up and begins to speak unintelligible words. He communicates by using sounds and facial expressions, communicating constantly changing moods and states of mind, addressing the viewer who in turn reacts unvoluntarily, without conscious decision. The emotions are recorded by GSR-sensors (Galvanic Skin Response). The signals produced are passed on by midi to a realtime video- and sound-editor and influences a variety of multi-media parameters. The unconscious emotional states thereby steer the flow of video images and influence the use of sound and image effects. The more relaxed the viewer is, the more his virtual counterpart will try to provoke, that is, the video images shown will be those of an actor acting aggressively. What is generated is a very individual experience, which will vary with each viewing by the same visitor. affectiveCinema may be understood as an approach to new strategies of incorporating theatre into the new media, and is, similar to Luc Courchesne’s work, related to interactive forms of the entertainment industry.
