Designing take over scenarios for automated driving: How does augmented reality support the driver to get back into the loop?

Highly automated driving allows the driver to temporarily turn away from the driving task, meaning he or she does not have to monitor the system. This leads to the challenge of getting the driver back into the loop, if the automation reaches a system boundary. This study investigates, whether augmented reality information can positively influence the take over process. Therefore we evaluated two augmented reality concepts. The concept “AR red” displays a corridor on the road to be avoided by the driver in a take over scenario. The concept “AR green” suggests a corridor the driver can safely steer through. Results indicate that the type of augmented reality information does not influence take over times, but considerably affects reaction type. Visual inspection revealed higher consistency in driving trajectories for participants following the proposed corridor of “AR green” concept as compared to trajectories of drivers confronted with the restricted zone of “AR red”.

An Experiential Perspective on Advanced Driver Assistance Systems

Abstract The objective of Advanced Driver Assistance Systems (ADAS) is to support drivers in mastering the driving task. Until now, the development of ADAS has mainly focused on technology, safety and comfort. This paper aims to complement this by a more experiential view. A study explored how Adaptive Cruise Control (ACC), as an example of ADAS, impacts people´s driving experience. It showed that ACC creates a gap between the driver and her car. This gap can be interpreted in two different ways. It is negative, when the “joy of driving” is in the fore, because it removes the feeling of mastery, control, being in charge and being one with the car. It is potentially positive, when the “joy while driving” is in the fore, because it creates the freedom to engage in pleasurable activities beyond driving. Unfortunately, the current concept of “supervisory control” for ADAS does not allow for the disengagement with driving. Based on our findings, we discuss crucial aspects to consider when designing ADAS from an experiential perspective. Zusammenfassung Advanced Driver Assistance Systems (ADAS) haben das Ziel, den Fahrer bei seiner Fahraufgabe zu unterstützen. Dabei konzentriert sich die Entwicklung auf technologische Aspekte, Sicherheit und Komfort. Dieser Artikel ergänzt dies um eine erlebnisorientierte Sicht. Eine qualitative Studie zeigt, wie Adaptive Cruise Control (ACC) das Fahrerlebnis verändert. ACC erzeugt eine Distanz zwischen Fahrer und Auto. Ist die “Freude am Fahren” im Vordergrund ist diese Distanz negativ, denn sie verringert Gefühle des Meisterns, der Kontrolle, des Verantwortlichseins und des “Einsseins” mit dem Auto. Ist die “Freude beim Fahren” im Vordergrund ist die Distanz potentiell positiv, denn sie erzeugt den Freiraum, sich mit anderen freudvollen Dingen jenseits des Fahrens zu beschäftigen. Leider erlaubt es das Konzept der “supervisory control” nicht, dem Fahrer diesen Freiraum wirklich zu geben. Auf dieser Basis diskutieren wir zentrale Punkte, die es zu berücksichtigen gilt, wenn man ADAS eher erlebnisorientiert gestalten möchte.

“It’s More Fun to Commute”—An Example of Using Automotive Interaction Design to Promote Well-Being in Cars

Automotive interaction design (AID) becomes more and more important. From advanced driver assistance systems to social media—the number of interactive systems available in cars increased substantially over the recent years. However, AID is still mostly concerned with making interaction either easy or exciting. In this chapter, we argue that AID should focus more on creating and shaping enjoyable and meaningful activities through sensible arrangements of interactive technologies. To advance this argument, we provide an overview of a well-being-oriented experiential approach to AID and discuss the Perfect Commute as an example of a well-being-oriented experiential interactive system.
