Visualizing the invisible, from service design to sustainability.
I was recently invited to deliver a talk at Emily Carr University of Art and Design about what interaction designers do and how interaction design factors into the worlds of design and art.
My talk "The Language of Interaction" (slides above) was my attempt to summarize the critical role that language plays in our efforts as designers and artists. In doing so, I touched upon the three challenges that all designers and artists face in trying to craft interactions…
1. Establishing a vocabulary, which allows you to articulate what discrete points of a systemic problem you may influence
2. Considering what metaphors may aid you in the modelling of an interactive product or service
3. Understanding how we weave together what we've experienced from our interaction with lateral disciplines to become better at practicing interaction design
To illustrate the last point, I created a timeline of my lifelong explorations as a designer and artist, and discussed how I couldn't have been an effective interaction designer without traveling through a range of related (and seemingly unrelated) disciplines. Over time, all of them were threaded together.
