Describing social and material interactions through formal methods

"To some extent, Formal Methods sit uneasily within interaction design. Human beings are rich, complex, nuanced, engaged in subtle and skilful social and material interactions; reducing this to any sort of formal description seems at best simplistic. And yet that is precisely what we have to do once we create any sort of digital system: whether an iPhone or an elevator, Angry Birds or Facebook, software is embedded in our lives. However much we design devices and products to meet users' needs or enrich their experiences of life, still the software inside is driven by the soulless, precise, and largely deterministic logic of code. If you work with computers, you necessarily work with formalism.

Formal Methods sit in this difficult nexus between logic and life, precision and passion, both highlighting the contradictions inherent in interaction design and offering tools and techniques to help understand and resolve them.

In fact, anyone engaged in interaction design is likely to have used some kind of formal representation, most commonly some sort of arrow and sketch diagram showing screens/pages in an application and the movements between them. While there are many more complex formal notations and methods, these simple networks of screens and links demonstrate the essence of a formal representation. Always, some things are reduced or ignored (the precise contents of screens), whilst others are captured more faithfully (the pattern of links between them). This enables us to focus on certain aspects and understand or analyse those aspects using the representation itself (for example notice that there are some very long interaction paths to quite critical screens)."

inFORM: prototype for a Dynamic Shape Display

"inFORM is a Dynamic Shape Display that can render 3D content physically, so users can interact with digital information in a tangible way. inFORM can also interact with the physical world around it, for example moving objects on the table's surface. Remote participants in a video conference can be displayed physically, allowing for a strong sense of presence and the ability to interact physically at a distance."

(Daniel Leithinger, Sean Follmer, Alex Olwal, Akimitsu Hogge, Hiroshi Ishii, 2013)
