Abstract:It is well known that different fundamental trade-offs in (semi-)autonomous systems affect performance of those systems. This study aims to extend these findings by examining how balancing off fundamental trade-offs in (semi-)autonomous systems affects trust. We therefore conducted an experiment and compared two groups of participants operating a simulated (semi-)autonomous car. One group was driving a car that was strictly following traffic rules, the other group operated a car that acted upon additional contextual information and would act against traffic rules where it might appear reasonable. During the experiment, both groups repeatedly rated their confidence in the car, predictability of its actions, perceived safety and perceived effectiveness of the car. In addition, participants could regain control over their car if they wanted to overwrite a decision. We compared both groups in a between-subjects design and found that confidence and perceived safety was rated higher when the car exclusively considered traffic rules when making decisions, while perceived effectiveness was rated higher when the car considered contextual information in addition. There was no significant difference regarding predictability of the car’s actions or the frequency with which participants regained control of the car. Based on additional exploratory analyses we performed, we hypothesize that whether participants followed an action proposed by the automated car or regained control of the car to perform another action was determined by a combination of the default action the car proposed and the presence or absence of risk, i.e., legal consequences for performing a certain action.
