Self-service technologies (SSTs) are becoming an increasingly important factor shaping the everyday environments in which we live. The aim of this one-day workshop is to explore key challenges for HCI and interaction design, related to current trends in the development and use of SSTs. The workshop will gather interested researchers and practitioners in order to (a) collaboratively identify a set of issues related to analysis, design, and evaluation of SSTs and (b) discuss potential approaches to understanding and crafting user experience with self-service technologies.
