In this chapter, the view that Interactive Architecture1 (IA) practice ought to produce (digital) interactive interventions designed to affect people’s actions and behaviours is firstly introduced. After presenting the challenges arising when integrating these two different conceptions of the word: Atoms and bits, reviewing the interpretations of IA and the lessons learnt from design methods theory in architecture, a novel way of approaching the intersection between architectural design, methodology, and emerging interactive technologies is proposed. This chapter attempts to make strong connections between design philosophy and project work, in aid of reinforcing the intellectual side of IA projects. Very often these types of projects are the result of technological pursuits rather than intellectual ones. Furthermore, this study demonstrates some strategies for ensuring the collaboration of design with related scientific and intellectual domains: architecture, computer science, and behavioural and social studies.
