In the installation Performative Ecologies Ruairi Glynn brings up the topic of interactive vs reactive and explores how architecture can interact with rather than react to human and environmental activity.

Any artifact that can be affected by a user can be said to be interactive if the term is used in its broadest sense. However, if the term is used whenever there is some kind of communication between a user and an artifact it risks becoming diluted. For the sake of the discourse it is perhaps therefore better to reserve interactive for two-way communication and to use the terms reactive and responsive for one-way communication.
