According to Krueger, "response is the medium." Rokeby seeks to create "a language of interaction [that is] intuititive." Jeremijenko asserts that "technologies are tangible social relations." Snibbe uses bodily interaction to portray interdependence.

Create a responsive environment.

Use video tracking (e.g., Cyclops) as the basis for the human interface to an interactive work. Focus on the details of human motion. What motion do you want to capture? How will you represent this with the tools you have? How will the humans know what to do?

Consider the demarcation of space. You may wish to somehow add cues to modify the space, in order to indicate to the human about the presence of affordances for interaction.

What will respond to this human motion? The choice is completely up to you. You can modify your audio composition. You can create a new Max patch, or use any other patch you've created in some other context. You can put together glue (perhaps with TCP/IP) to interface to another application.

Consider the "environment". The environment is partly software, party physical. It is an interface border zone. It includes physical space, and digital system response. Define the environment intentionally.

criteria of evaluation

• Your consideration of human motion, and how you use it.
• The definition of the environment, such as the cues which tell people where they are and what the can do.
• The mappings between physical gesture and/or presence, and the environment. The characteristics of the responsiveness.
