Abstract

An experiment (N=24) was conducted with a spoken dialogue system (a smart thome system), in which the users carried out several tasks with the system and rated its usability. Users’ interactions were analyzed from the perspective of human error research done in human factors and cognitive ergonomics, distinguishing between goal-, concept-, task-, and command-level errors. This paper raises the question of how the interrelationship between errors and usability perceptions should be studied. Preliminary results are presented from correlational and factor- analytical approaches.
