Thin slices of interaction : predicting users’ task difficulty within 60 sec
Ferreira, João Pedro; Sousa, Marta Noronha e; Branco, Nuno; Ferreira, M. J.; Otero, Nuno; Zagalo, Nelson; Branco, PedroWe report on an exploratory study where the first 60 seconds of the video recording of a user interaction are used to predict the user’s experienced task difficulty. This approach builds on previous work on “thin slices” of human-human behavior, and applies it to humancomputer interaction. In the scenario of interacting with a photocopy machine, automated video coding showed that the Activity and Emphasis predi...

The evaluations were performed using a five-point scale and the average error of the evaluat...
