Heiko Hecht is a professor of experimental psychology with a research focus on perception. Typical themes are perception and technology, virtual reality, intersensory integration, intuitive physics, picture perception as well as simulator and simulator-sickness - the topic of his Bielefeld talk.

Next generation automotive hardware and user interfaces are increasingly pre-tested in driving simulators. What are the potential limitations of such simulations? We determined the relative and absolute validity of five different driving simulators at the Daimler AG, based upon a dual-task paradigm that involved driving and communicating with the on-board infotainment system. The tasks were chosen according to the guidelines of the Alliance of Automobile Manufacturers (2006).
We compared performance in the simulators to on-road driving, and hypothesized that not only simulator characteristics, but also user characteristics, such as simulator sickness, gender, or age, influence behavioral validity. We demonstrated the usefulness of all simulators on a relative and partially on an absolute level.
Moving-base simulators were superior to fixed-base simulators, but not dramatically so. Simulator sickness was associated with impaired performance. Interestingly, age and gender modulated performance in fixed-base simulators, whereas they did not explain any variance in moving-base simulators or real-world driving.
