I gave a lecture at Stanford's CS547 course on HCI, and of course it was on'Design Fiction.' This is interesting to listen back on as I forgot about the examples I used 'early on' that came specifically from film. This was during the 'diegetic prototype' emphasis of things. Drawing on examples from films like 'Jurassic Park' and '2001: A Space Odyssey,' I showed how storytelling and these diegetic prototypes help communicate complex, speculative, often futuristic concepts. I describe the cultural impact of Design Fiction on technological perception and legal precedents, particularly in relation to augmented reality and user interfaces. Practical projects such as the Quick Start Guide for a Self-Driving Car help highlight the importance of making emerging technologies accessible. Examining material culture, leaning on humor and satire is highlighted as useful ways to engage with future possibilities.
