Anja Naumann received her M.Sc. (Diploma) degree in Psychology from Dresden University of Technology in 1998. Working as a research associate with the chair of Cognitive- and Engineering Psychology at Chemnitz University of Technology from 1998 to 2005, she received a Ph.D.(Dr.rer.nat.) in Engineering Psychology in 2004. From 2005 to 2006 she worked at the Center of Human-Machine Systems at TU Berlin.

Since 1998, Anja Naumann has been engaged in Human-Machine Interaction, mainly investigating human cognitive processes. Research topics were, for example, knowledge acquisition with Web-based teaching systems, driver distraction by in-car information systems, design of adaptive traffic signs, and design of user interfaces. Since October 2006 working as a Senior Scientist in Usability Research at T-Labs, she is developing and applying new usability and acceptability evaluation methods for Information and Communication Technology. She is also working on intuitive use of user interfaces. She is member of the Usability Professionals Association and the Society for Computers in Psychology.

Abstract This paper describes initial results from an evaluation study on the use of different modalities. The application, a web-based media recommender and management system called MediaScout, was installed on two multimodal devices, and on one unimodal device as a control condition. The study aims to investigate whether users make use of multimodality if it is offered and under which circumstances they do so. Moreover, it was studied whether users' stated modality preferences match their actual use of the modalities. The results show that users do not make use of all modalities for all tasks. Modality usage is determined by the task to be performed, as well as the efficiency of the modality for achieving the task goal. Both modality usage and the range of offered modalities seem to influence subjective user ratings.
