INTERACTIVE SYSTEMS

Research

David Ahlström

Associate Professor

David’s main research interests revolve around the design and empirical evaluation of novel user interfaces and interaction techniques for smartphones and smartwatches, such as map navigation, menu, and image browsing interfaces, and in-air hand gestures, vibration-based input, and touch-commands.

Anton Josef Fercher

Predoc Scientist

In his current research, Anton investigates new ways to support (end-) users in the do-it-yourself configuration process of Smart Homes. Here his special focus lies on the application of augmented reality based interfaces to provide users with technical background and guidance, as well as possibilities of risk-less exploration on demand.

Martin Hitz

Professor

Martin is heading the group, currently as a 25% professor (and a 75% vice rector). His research ideas find their way into the work of his colleagues, especially the more junior ones. The last dissertations completed under his supervision dealt with natural, intuitive and calm interaction.

Gerhard Leitner

Associate Professor

Gerhard’s research areas are human system interaction, usability and user experience, with a special focus on smart homes, specific user groups (elderly, private home owners) and specific goals (active and assisted living, comfort enhancement, efficient and easy configuration and control).
