The facilitated integration of technology into people's lives highlights the importance of examining its impact on experience and behavior. Experimental approaches help to determine the underlying psychological processes of this impact. This symposium aims to highlight the value of the experimental approach in the applied setting of Engineering Psychology and Human Factors by presenting recent research projects and results in various application fields. The first talk by Nadine Schlicker and Markus Langer presents findings of a study that aimed to compare justice perceptions of decision recipients between human and automated agents and to investigate how these perceptions are affected by explanations. The second talk by Veronica Hoth, Maria Ivanova, and Stefan Brandenburg examines the impact of three different Design Patterns of a cookie banner on participants' ratings of user experience and trust. The third talk by Markus Gödker, Tim Schrills, and Thomas Franke presents an electric vehicle driving simulator experiment that investigated the drivers' mental representation of energy consumption, its development over time, and its link to eco-driving. The fourth talk by Luisa Heinrich and Martin Baumann examines the effects of different interaction strategies on the take-over behavior in automated vehicles. The fifth talk by
Elisabeth Wögerbauer addresses the effect of dissociating viewpoints through the use of camera-monitor systems on time-to-contact estimation. The results of a laboratory experiment in which the horizontal position of the camera was varied will be reported. The sixth talk by Matthias Arend and Verena Nitsch investigates situation awareness during telemanipulation. In the presented experiment they study the situation models of human operators in a situation in which they control a complex robotic system with various end-effectors at a distance.

The effect of horizontal camera position on time-to-contact estimation when using a camera-monitor system

As mirrors in the automobile are increasingly replaced by camera-monitor systems, it is important to understand the potential consequences of different camera placements. Uncommon camera positions offer potential advantages such as a different or larger field of view. However, decoupling the visual axes may lead to altered perception. Previous findings indicate that if the camera's position is changed vertically, distance is overestimated for higher and underestimated for lower camera positions, as compared to the standard position of the driver-side mirror. It is, however, unclear which effect the change of the camera position in horizontal direction has on time-to-contact estimation. Therefore, we conducted a study with a prediction motion paradigm in which subjects had to estimate the time-to-contact of a vehicle approaching from behind. In addition to the camera position and the actual time-to-contact, the speed of the approaching vehicle and the rear visibility of the own vehicle were varied. The results of the currently ongoing study as well as its implications for the design of camera-monitor systems will be reported.
