interACT @ the AutoUI 2018

23 September 2018 | Toronto, Canada

The workshop entitled ‘AutoUI Workshop on Methodology: Evaluating Interactions between Automated Vehicles and Other Road Users – What Works in Practice?’ took place on 23rd of September 2018 at the Bahen Centre of the University of Toronto. Partners from the interACT team were among the organisers along with scientists from the Eindhoven University of Technology in Netherlands, the Research Institutes of Sweden (RISE), and the University of Leeds Institute for Transport Studies. The workshop was offered in conjunction with the 10th International Conference on Automotive User Interfaces and Interactive Vehicular Applications (AutoUI 2018). This workshop focused on identifying the strengths and weaknesses of various methodologies that could potentially be used to study such interactions. The objective lied in determining the proper experimental design, sensitivity of metrics for measuring user behaviour, ecological validity, generalizability of findings, extraction of insights regarding how findings can be translated into actionable requirements, and the alternatives for conducting longitudinal field studies.

The workshop was introduced with challenges that researchers are facing when evaluating interaction with automated vehicles and other road users. In addition, some of the main themes that were covered during the workshop were: the ecological validity of (controlled) experiments, the effective measurement of behavioural impact, the question of which methodology for which type of insight and the efficacy of Wizard of Oz (WOZ) setups for studying interactions.
The workshop was of an interactive nature and involved hands-on activities. Every organization partner presented his own experience with such research. They identified 5fiveuse cases with and without eHMI. They split the group in five subgroups and assigned each subgroup to a use case. Each organization partner acted as a moderator in a group. The groups were asked to design a study to investigate efficient interaction for their particular use case.
It consolidated existing knowledge, identify recurring issues, and explore the path towards resolving these issues. The outcome will be compiled into a paper in order to share this valuable knowledge with a broader research community.
