For immersive experiences, augmented reality (AR) and virtual reality (VR) require intuitive and natural user interfaces (NUIs) that allow users to express their intentions and actions as directly as possible. The focus is on innovative interaction concepts and techniques based on Direct Manpulation in 3D and gestures, Full Body and Embodied Interaction as well as Free Hand Interaction. Since VR takes users from reality into a virtual world, new methodological challenges and questions arise in the evaluation of NUIs.
This research area investigates the application of semantic technologies for innovative digital media and user interfaces. For the realization of intelligent digital media systems of the next generation, it is necessary to better understand and represent user intentions, digital content, and the interaction in these systems by machine.
Games User Reseach (GUR) refers to a research field that deals with the interaction between interactive experiences and users. The research focuses on the effects of games on cognitive processes and player behavior. In the context of GUR, we investigate which motivational factors occur during the use of games and how these can be used, for example in the design of serious games, to ensure long-term motivation. Furthermore, this research strand is concerned with identifying factors and data that can explain or predict player behavior. In the context of the overarching research area of Entertainment Computing (EC), members of the Digital Media Lab are conducting research on topics such as Player Modeling/Adaptation, Serious Games, and Games for Health.
The increasing infiltration of our everyday life with applications and services based on computer technology also requires the design of corresponding interfaces between humans and machines. Understanding human characteristics and behaviors, as well as the situations in which humans interact with computers, enables the development of new and advanced interaction paradigms.
The Digital Media Lab's research focuses on the topic of "usable security". Current research approaches in the field of human-technology interaction (HCI) are applied to information security issues. Users are therefore enabled to better understand security concepts in order to act more confidently in an increasingly digitalized world. In particular, we use various HCI methods such as serious games, gamification and virtual/augmented reality to make information security more tangible and at the same time more understandable for people. Typical application areas of our methods for Usable Security are mobile devices, smarthome applications and also the Internet in general. Our research in this area is funded by the Klaus Tschira Foundation as well as the BMBF.
