Recognition of car warnings: An analysis of various alert types. Sabic, E., Mishler, S., Chen, J., & Hu, B. In Conference on Human Factors in Computing Systems - Proceedings, volume Part F1276, pages 2010-2016, 2017. doi abstract bibtex Warnings are integral to ensuring the safe operation of a vehicle. The use of auditory alerts and warnings has the potential to alleviate drivers' workload, increase drivers' situation awareness, and facilitate efficient and safe driving. The present study assessed the ability of individuals to react to auditory warnings. The warnings took the form of text-to-speech (TTS), spearcons at two levels of linear compression, and auditory icons. To assess usability, the NASA Task Load Index and an annoyance question were used. Participants pressed a space bar when they recognized a warning, and then identified auditory warnings by selecting a picture corresponding to the meaning of the warning. The results showed that participants responded to the fastest spearcon warnings more quickly compared to TTS and auditory icons. Responses to auditory icons were slowest compared to all other auditory types. Importantly, responses to spearcon warnings were no less accurate in comparison to TTS warnings.
