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.

Technology advancements allow car manufacturers to introduce highly automated vehicles into the market in the foreseeable future. However, as long as vehicles are not fully autonomous, transitions between different levels of automation take place and imply shifts in the driver's role and responsibilities. In case of system limits, the driver may intervene in the driving task. As drivers will likely perform non-driving-related activities during automated driving, transitions to lower levels require the driver to re-establish situation awareness to intervene safely. Therefore, this work discusses two strategies how the driver’s situation awareness might be re-established before taking over the driving task. A 2 x 2 within-subjects design was employed with transition strategy (monitoring or initiating a maneuver) and type of transition (manual or automated maneuver) as independent variables. In a driving-simulator study, participants experienced a highly automated drive on a rural road. While participants engaged in a non-driving related task (NDRT), the vehicle approached a rear-end collision, due to which an intervention request was issued: participants were either asked to monitor the environment or to initiate an overtaking maneuver upon system availability. The subsequent maneuver had to be performed either manually (involving a take-over request) or was performed by the vehicle in automated mode. Effects on gaze behavior, manual driving performance, and subjective measurements were investigated. Both strategies decreased the odds of interleaving and positively affected driving safety. The strategies are discussed in light of their suitability for different transition contexts, and recommendations for the design of control transitions are derived.
