ABSTRACT<br />
This tutorial will briefly introduce: (1) the evolution of driver<br />
distraction, (2) key definitions that have been proposed, (3)<br />
research methods used in the assessment of distracted driving, (4)<br />
the sensitivity of different techniques for measuring user interface<br />
dem<strong>and</strong>, e.g. eye tracking, physiological monitoring, task <strong>and</strong><br />
driving performance, (5) differences in the expression of visual,<br />
manipulative <strong>and</strong> cognitive dem<strong>and</strong>s on driving behavior, <strong>and</strong> (6)<br />
current governmental <strong>and</strong> industrial efforts to reduce distracted<br />
driving.<br />
Keywords<br />
Eye-tracking, physiology, driver behavior, task performance,<br />
safety<br />
1. INTRODUCTION<br />
The topic of distracted driving has been around since the early<br />
days of the automobile. In 1930 Nicholas Trott wrote in the New<br />
York Times, “A grave problem that developed in New<br />
Hampshire… now has all the motor-vehicle commissioners of the<br />
eastern states in a wax. It's whether radios should be allowed on<br />
cars. Some states don't want to permit them at all—say they<br />
distract the driver <strong>and</strong> disturb the peace…The [Massachusetts]<br />
commissioner thinks the things should be shut off while you are<br />
driving…The whole problem is getting very complex, but the<br />
upshot is that you'll probably be allowed to take your radio<br />
anywhere, with possibly some restriction on the times when you<br />
can play it.” The technologies that can distract drivers have<br />
arguably increased in complexity since Trott’s day, but the debate<br />
on what interactions are appropriate to complete safely while<br />
driving remains largely intact today. While thous<strong>and</strong>s of articles<br />
have been written on the topic, it is essential that researchers<br />
consider numerous factors when interpreting the literature.<br />
2. OVERVIEW OF THE TUTORIAL<br />
Traditional, experimental research on distracted driving has<br />
largely focuses on assessing behavior changes with a moderate to<br />
high distraction task, e.g. drivers react more slowly when on a cell<br />
phone [6]. In other lines of research effects of dem<strong>and</strong>s are<br />
difficult to interpret, as attentive drivers may not fully engage in<br />
the task at h<strong>and</strong> [2]. The optimization of interfaces to minimize<br />
driver distraction requires a broader understudying of the<br />
problem. The larger question is, at what level of dem<strong>and</strong> does a<br />

driver’s behavior begin to be affected? Recent work [2, 4] shows<br />
that driver behavior is impacted by the simple activity of repeating<br />
a series of numbers (0-back).<br />
The content of this tutorial will be geared towards providing<br />
participants with an overview of important considerations in the<br />
development of empirical research <strong>and</strong> the interpretation of<br />
previous research on distracted driving. Emphasis will be placed<br />
on underst<strong>and</strong>ing the appropriate use of techniques to provide<br />
sensitive measures of driver behavior. Illustrations of previous<br />
research will be presented where appropriate. Effort will be placed<br />
on providing attendees with an underst<strong>and</strong>ing of the effective use<br />
of different techniques for measuring dem<strong>and</strong> <strong>and</strong> potential<br />
pitfalls.<br />
3. SUGGESTED READING<br />
For a comprehensive discussion on factors involved with driver<br />
distraction [3] is a good desk reference. Suggested reading in<br />
preparation for this tutorial include the topic of task duration [1],<br />
eye tracking <strong>and</strong> glance based analysis of visual dem<strong>and</strong>s [5], <strong>and</strong><br />
the impact of cognitive dem<strong>and</strong>s on physiology, visual attention<br />
<strong>and</strong> driving performance [2, 4].<br />
