Iqbal, Shamsi T., Horvitz, Eric, Ju, Yun-Cheng and Mathews, Ella (2011): Hang on a sec!: effects of proactive mediation of phone conversations while driving. In: Proceedings of ACM CHI 2011 Conference on Human Factors in Computing Systems 2011. pp. 463-472.

Conversing on cell phones while driving is a risky, yet commonplace activity. State legislatures in the U.S. have enacted rules that limit hand-held phone conversations while driving but that allow for hands-free conversations. However, studies have demonstrated that the cognitive load of conversation is a significant source of distraction that increases the likelihood of accidents. We explore in a controlled study with a driving simulator the effectiveness of proactive alerting and mediation of communications during phone conversations while driving. We study the use of auditory messages indicating upcoming critical road conditions and placing calls on hold. We found that such actions reduce driving errors and that alerts sharing details about situations were more effective than general alerts. Drivers found such a system valuable in most situations for maintaining driving safety. These results provide evidence that context-sensitive mediation systems could play a valuable role in focusing drivers' attention on the road during phone conversations.

Iqbal, Shamsi T., Ju, Yun-Cheng and Horvitz, Eric (2010): Cars, calls, and cognition: investigating driving and divided attention. In: Proceedings of ACM CHI 2010 Conference on Human Factors in Computing Systems 2010. pp. 1281-1290.

Conversing on cell phones while driving an automobile is a common practice. We examine the interference of the cognitive load of conversational dialog with driving tasks, with the goal of identifying better and worse times for conversations during driving. We present results from a controlled study involving 18 users using a driving simulator. The driving complexity and conversation type were manipulated in the study, and performance was measured for factors related to both the primary driving task and secondary conversation task. Results showed significant interactions between the primary and secondary tasks, where certain combinations of complexity and conversations were found especially detrimental to driving. We present the studies and analyses and relate the findings to prior work on multiple resource models of cognition. We discuss how the results can frame thinking about policies and technologies aimed at enhancing driving safety.
