Designing for the Worst Day of Your Customer's Life
10 December 2025 from 7pm to 8:30pm (Toronto time) 

 As designers, we often measure success in terms of performance, reliability, and efficiency. But what happens when our systems are pushed to the edge - when users are injured, disoriented, or in shock? On Ford's Safety & Security team, I design features like 911 Assist, Stolen Vehicle Services, and Cabin Occupant Detection - products I pray our customers never have to use. In this high-stakes design space, failure isn't an option because the consequences are severe: a confusing interface following a collision could cost precious seconds, a poorly designed stolen vehicle recovery flow could leave someone stranded, and an overlooked edge case in child detection could be fatal. This isn't your typical UX process optimizing for engagement - here, getting it right is the only metric that matters.

Presented by Sarika Goel, currently a digital product designer for FORD.

Interactive Inference and the Potential Energy of Actions
11 December from 7pm to 8pm at the DGP Lab, Bahen Centre 

Dr. Roel Vertegaal  Dr. Roel Vertegaal, Professor of HCI and director of the Human Media Lab at Radboud University in Nijmegen (Netherlands), presents a theory for the design of interactive systems based on cognitive neuroscience called Interactive Inference. Based on the neuroscience theory of Active Inference, it elegantly explains how users process tasks by first predicting the world around them, then choosing to learn or act when their predictions do not correspond with their observations. He will discuss how quantifying the amount of surprise in a task can produce elegant behavioural laws that appear to be governing user performance and error, including Fitts’ Law. Surprise is the amount of information processed when performing a task that brings the world closer to the state you predicted. In this talk, he'll show how it appears to also function as a physics equation, e.g., describing potential energy when planning movements. He'll conclude with some examples of how the study of surprise might lead to more intelligent interactive systems.
