This book describes an extension of the user behaviour simulation
(UBS) of an existing tool for automatic usability evaluation (AUE).
This extension is based upon a user study with a smart home system.
It uses technical-sociological methods for the execution of the
study and the analysis of the collected data. A comparison of the
resulting UBS with former UBSs, as well as the empirical data,
shows that the new simulation approach outperforms the former
simulation. The improvement affects the prediction of dialogue
metrics that are related to dialogue efficiency and dialogue
effectiveness. Furthermore, the book describes a parameter-based
data model, as well as a related framework. Both are used to
uniformly describe multimodal human-computer interactions and to
provide such descriptions for usability evaluations. Finally, the
book proposes a new two-stage method for the evaluation of UBSs.
The method is based on the computation of a distance measures
between two dialogue corpora and the pair-wise comparison of
distances among several dialogue corpora.
