Observing users’ behavior is insightful to understand the ways in which they approach and manage technological devices. The video-recording of users’ behavior allows to analyze offline their actions and attitudes, thus providing an objective investigation. HIT Research Center is provided with two full systems for the computer-assisted video analysis, both running The Observer XT by Noldus.

The Observer supports a deep analysis of the users’ behavior by allowing the experimenter to score systematically all the relevant events happening in a given video recording. The Observer can be coupled with other sensing technologies, e.g., EDA and eye-tracker, thereby providing synchronized recordings of the behavior and physiological signals.
