    Join our workshop „Emotions in the Age of Automated Driving – Developing Use Cases for Empathic Cars“ at MuC’19:

    Improving user experience of highly automated vehicles is key to increase their acceptance. One possibility to realize this is the design of empathic cars that are capable of assessing the emotional state of vehicle occupants and react to it accordingly by providing tailored support. At the moment, the central challenge is to derive relevant use cases as basis for the design of future empathic cars. Therefore, we propose a workshop that aims to bring together researchers and practitioners interested in affective computing, affective interfaces and automated driving as forum for the development of a roadmap towards empathic vehicles using design thinking methods. During the workshop, we will gain a common understanding of the central concepts and listen to impulse talks about current and recent projects on emotions during automated driving. Based on this, relevant use cases are generated in group work and discussed with the goal to identify potential research and knowledge gaps. Finally, a road map for research towards the realization of automated empathic cars is formulated from the results.

    Abstract

    Objective: The present study has 3 objectives: First, we wanted to examine whether the Cycling Anger Scale (CAS) applies to German professional bike messengers, because this scale was previously developed with nonprofessional cyclists in Germany. Second, we wanted to look at possible differences in cycling anger experience and expression between professional German bike messengers and nonprofessional German cyclists. Third, we explored whether cycling anger is somehow related to driving anger and general anger.

    Methods: We applied German versions of the CAS, the Driving Anger Scale (DAS), and the State–Trait Anger Expression Inventory (STAXI) to a sample of 123 professional German bike messengers. Then we compared their ratings with the results of 421 nonprofessional German cyclists.

    Results: Regarding our first objective, results indicate that the CAS model fit is better for nonprofessional than for professional cyclists. However, the CAS in a slightly modified version can be used for professional cyclists as well. As for our second objective, we show that professional cyclists experience significantly less cycling anger than nonprofessional cyclists. However, bike messengers report more frequent aggressive cycling behaviors when angry, indicating a weaker link between trait anger while cycling and aggressive behavior among professionals. Thirdly, we found relations between cycling anger, driving anger, and general anger.

    Conclusions: We conclude that the CAS in its slightly modified 13-item version with the established 4 subscales produces an acceptable model fit and can be applied to professional German bike messengers for further research purposes or applied issues; for example, traffic education or self-awareness in terms of accident prevention behaviors. In addition, for professional cyclists, less anger does not result in less aggressive cycling behaviors. Subsequent research should explore the role of anger in behavioral regulation of cyclists’ unsafe cycling behaviors taking different levels of experience and professionalism into account in order to reduce adverse effects of anger on traffic safety.

    Abstract

    Objective: The main objective of this article is to examine whether the Driving Anger Expression Inventory (DAX) applies to German drivers because this scale has previously been given to drivers in many different countries.

    Methods: We applied German versions of the DAX, the Driving Anger Scale (DAS), and the State-Trait Anger Expression Inventory (STAXI) to a sample of 501 German drivers. We computed confirmatory factor analysis and principal axis factoring (PAF) analysis to examine the structure of driving anger expression in Germany. Finally, we related the drivers’ anger exp ression scores to their driving anger experiences and their general anger propensities to assess the validity of the DAX for German drivers.

    Results: Results indicated that the DAX’s original factor structure does not apply to German drivers because the confirmatory factor analysis did not show a good model fit. An item analysis revealed that many DAX items had no meaningful variability. They were excluded from further analysis. The subsequent PAF analysis indicated that German drivers do not use personal physical aggression to express their driving anger. Instead, they reported unique preventive anger expression management behavior. In addition, their driving anger expressions were significantly related to their driving anger experiences and their general anger propensities indicated the validity of the refined DAX for German drivers.

    Conclusions: We conclude that German drivers do not use strong behaviors to express their driving anger. Many statements of Deffenbacher et al.’s (Behav Res Ther. 40:717–737, 2002) original American questionnaire were not applicable for our sample of German drivers. These findings are in line with several other studies showing discrepancies in driving anger expression in various countries. Future investigations should examine the reasons for discrepancies in driving anger expression.

  • Cyclists’ anger experiences in traffic: The Cycling Anger Scale

    Abstract: Research on emotions in road traffic has focused on car drivers rather than on cyclists. However, cyclists experience cycling anger and its consequences as vulnerable road users, i.e., without having a car-like protection zone around them. To address the issue of cycling anger, we suggest a psychological measure assessing cyclists’ anger experiences in traffic, the Cycling Anger Scale (CAS). This questionnaire assesses cyclists’ anger experiences in interaction with their cycling environment. A principal component analysis and a following confirmatory factor analyses with two different samples proposed a 14 items questionnaire solution with four subscales: police interaction, car interaction, cyclist interaction, and pedestrian interaction. Alpha reliabilities were acceptable to good. The CAS correlated significantly with the Driving Anger Scale (DAS) for car drivers and with the general State-Trait Anger Expression Inventory (STAXI) suggesting convergent validity. Additionally, we examined the relations between cycling anger, demographics, and self-reported cycling behavior. We conclude that the CAS provides a complementary efficient instrument for measuring cycling anger in road traffic.

    Our workshop ‚Emotional GaRage‚ at Auto UI 2018 in Toronto was the most well attended workshop at Automotive UI. The workshop was planned as a design thinking workshop to explore and design to user experiences of emotions in the vehicle. The workshop consisted of several exercises exploring the ways in which emotions could be detected, the relative difficulty of detecting different emotions in different channels, identifying the most significant emotions that occur during driving, speculating on how autonomous driving will change the emotions associated with driving and a design prototyping session in which people prototyped solutions to emotionally difficult situations on the road. At the end of the workshop we recorded one minute videos reflecting on our experiences.

    Oehl, M., Kamps, M., Wesa, M. & Sutter, C., (2018). Was ältere Nutzer Assistenzrobotern zutrauen – Eine Frage des Designs?. In: Dachselt, R. & Weber, G. (Hrsg.), Mensch und Computer 2018 – Tagungsband. Bonn: Gesellschaft für Informatik e.V..

    Zusammenfassung:
    Diese experimentelle Studie untersucht die Akzeptanz älterer Nutzer für persönliche Roboterassistenz in unterschiedlichen Aufgabenbereichen. Auf Basis der von Smarr et al. (2014) entwickelten „Assistance Preference Checklist“ beurteilten ältere Probanden ihre Akzeptanz für Roboterassistenz. Als Stimulusmaterial der experimentellen Variation wurden Fotos zweier unterschiedlicher Robotertypen verwendet, um zusätzlich den Einfluss des Designs auf die Akzeptanz zu untersuchen. Die Probanden zeigten eine grundsätzliche Offenheit für Roboterassistenz, diskriminierten jedoch zwischen den Tätigkeitskategorien. Tätigkeiten mit viel Interaktion zwischen Benutzer und Roboter wurden weniger akzeptiert als z. B. Haushaltsaufgaben. Diese Ergebnisse sind im Einklang mit ähnlichen Studien. Das Design des Roboters hatte nur einen geringen Einfluss auf die Bewertung.

    Abstract: Previous research shows that anger and aggression among road users lead to maladjusted driving and a higher risk of accidents. Especially cyclists as vulnerable road users have a high risk of being injured if they are involved in accidents. This paper examines reasons for cycling anger in two studies. The first study aimed at identifying anger provoking events. Seventy-three cyclists were invited to discuss anger provoking events in a focus group setting. These events were rated regarding their anger intensity, clustered within focus groups, and aggregated across all groups. The first study revealed 208 unique cycling anger provoking events of varying anger intensity that were summarized in six clusters. The second study aimed at validating these anger provoking events, the ratings, and the clusters. Here, 129 participants were asked to complete a four-time point diary study (over the course of ten days), in which they registered all anger provoking events that they experienced while cycling. The results of this study validated most of the anger provoking events of the first study. Both studies show that most anger provoking events are related to conflicts between cyclists with other road users like car drivers and pedestrians. Moreover, conflicts with car drivers seem to cause stronger anger among cyclists than conflicts with other cyclists or pedestrians. Implications for further research and the planning of road infrastructure are discussed.
