This book constitutes the thoroughly refereed post-proceedings of the 13th International Workshop on Design, Specification, and Verification of Interactive Systems, DSVIS 2006, held in Dublin, Ireland in July 2006. The 19 revised full papers presented together with 1 keynote paper, and 2 working group reports were carefully reviewed and selected from 57 submissions during two rounds of reviewing and improvement. The papers are organized in topical sections on HCI research, critical systems, model based development, cognitive aspects of interaction, use of models, haptics and multimodality, prototyping and evaluation, supporting user interface development, and group discussions.
