Developing Gaze and Movement Key Performance Indicators for User Experience Assessment
There’s nothing quite as delightful as using a well-designed product, especially a piece of software. A field of research known as User eXperience (UX) tries to define measures that describe what a good design feels like. While conventional measures of UX for software work well (how long things take, whether you complete your task successfully), we suggest that tracking your eye and hands will reveal other useful information. These easy-to-get measures, which we call Gaze and Movement Assessment Key Performance Indicators (GaMA KPI), are calculated from where the eyes look, how the hand moves and their coordination, to tell us how the user’s experience is going. We have designed a task that is similar to a menu system that someone might find in a typical video game. Users interact with the menu while we record both their gaze and hand positions throughout. We have found promising KPIs that are novel and only possible to generate using gaze and movement data. We hope to continue data collection to generate new, more advanced KPIs, that tell us more detailed information about the user’s experience.
