Brian A. Smith giving his talk "Computers as Partners in Human Ability" today at Aalto. Impressive work. I especially appreciate his work on creating auditory interfaces that allow blind users play real-time video games like driving. Brian is Yue Jiang's opponent and visiting us today and tomorrow.

Just presented "WigglyEyes: Inferring Eye Movements from Keypress Data" at Ubicomp/ISWC'25. It's a method that, given keypress data only, infers how users move their eyes when they type. It uses a user simulator for data augmentation.

John R. Platt's Strong Inference 1958 (Science) keeps giving. Reading it this morning I found this gem. To push forward HCI, we need to do the same: sit down, think, and build models that help us tease out the fundamental questions -- and only then run empirical studies. Not the other way around.

The textbook is much more comprehensive than any introductory class needs. That's why we offer recommendations in Preface for courses in different contexts: computer science, design, engineering, social sciences, and specialized courses. Preface here:

Our new textbook isn't just about the essentials of research in HCI, it also offers guidance to those who entertain HCI as their future careers. My own two favorite bits are on how to read a paper critically and selecting HCI problems that matter.

Computational models of human perception have been stuck with visual saliency, which has little ecological validity. Who looks at a display with no task in mind? One reason for this fixation has been that there simply are no high quality datasets for other tasks. Well now there is for visual search:

The paper sheds new light on human error. While earlier work has shown mechanisms that cause error, it has not looked at errors in closed-loop control. In Typoist, errors are to a some degree (not fully) a choice. It gives a much richer account of speed-accuracy trade-off.
