User Experience

Research Topics:

• Human-Computer Interaction
• Human-Human Interaction
• Speech & Multimodal Interfaces
• Usability Evaluation

• Speech & Voice
• First Impression
• Attitudes


Benjamin Weiss joined the Quality and Usability Lab in January 2007. He studied communication science & phonetics, educational studies and Scandinavian studies at the universities of Bonn, Trondheim and Berlin. After his graduation in 2002, he was with the “Graduiertenkolleg” at the Linguistics department at Humboldt University Berlin, doing his dissertation on speech tempo and pronunciation. He received his Ph.D. in Linguistics in 2008. In September 2008, he evaluated embodied conversational agents as Visiting Fellow at the MARCS Auditory Laboratories, University of Western Sydney, Australia. Currently, he is working on Likeability and Human-Computer Interaction, e.g. evaluating quality and usability of multimodal interfaces.
