There is currently a distinct lack of design consideration associated with autonomous vehicles and their impact on human factors. Research has yet to consider fully the impact felt by the driver when he/she is no longer in control of the vehicle [12]. We propose that spatialised auditory feedback could be used to enhance driver awareness to the intended actions of autonomous vehicles. We hypothesise that this feedback will provide drivers with an enhanced sense of control. This paper presents a driving simulator study where 5 separate auditory feedback methods are compared during both autonomous and manual driving scenarios. We found that our spatialised auditory presentation method alerted drivers to the intended actions of autonomous vehicles much more than all other methodsand they felt significantly more in control during scenarios containing sound vs. no sound. Finally, that overall workload in autonomous vehicle scenarios was lower compared to manual vehicle scenarios. [less ▲]

This paper presents the findings from an observational field study conducted with 8 car drivers. The study attempted to create a taxonomy of sounds that present information to people whilst driving. We also aimed to determine whether participants noticed these sounds as they occurred and whether they paid attention to them. Furthermore, we asked the participants subjective questions regarding particular sonic attributes and their ability to catch driver’s attention. It was concluded that although certain sounds occur regularly, differing levels of attention are given to each depending on the information they present. Our study also revealed that while all sonic attributes play an impact in catching driver’s attention, some aspects are more noticeable than others. We conclude with a discussion of our future directions with regards to the findings obtained from our observational field study and outline the plan for our next study. [less ▲]
