Using Advisory 3D Sound Cues to Improve Drivers' Performance and Situation Awareness

MinJuan Wang, Sus Lundgren Lyckvi, Chenhui Chen, Palle Dahlstedt, Fang Chen
2017 Proceedings of the 2017 CHI Conference on Human Factors in Computing Systems - CHI '17  
Sounds however, are mainly used to alert or warn drivers together with visual information.  ...  But, more importantly, the results also point towards the advantages and limitations of the use of advisory 3Dsounds in cars, e.g. attention capture vs. limited auditory resolution.  ...  We would like to thank Fredrik Hagman (Volvo Cars) who designed the sound samples, as well as Samuel Palm (Volvo Cars) who provided continuous support and design insights throughout the entire project.  ...

OUP accepted manuscript

2020 The Condor  
Interestingly, approach type had no effect on alert behavior, indicating a 3-m decrease in flight altitude from the overhead approach to the head-on approach did not enhance alert responses.  ...  As far as the effect of sound, blackbirds showed their alert responses earliest to the predator model, despite it being the quietest drone, evidence that sound did not prompt the initial alert.  ...
