Posters at Driving Assessment 2007

Driving Assessment 2007 featured three poster sessions. One of these (the hybrid session) was accompanied by what the Ubicomp and Pervasive conferences call one-minute madness (in the DA version the sound of a gong was embedded in the presenter’s Powerpoint slide and the goal of course was complete your presentation before the gong).

Here are a couple of words about several posters that I liked. First, there was Ensar Becic’s poster on the effects on driving performance of a conversation with a passenger or on a cell phone. Ensar is a graduate student in the HPP lab at UIUC. I thought it was interesting that they found that driving performance was worse (!) when participants only drove and did not engage in a conversation. We found something similar in our work that will be published at Interspeech 2007, although we did not discuss this in the paper (partly because we don’t have an explanation for it yet). Here’s a picture of Ensar discussing his poster:

I also liked Eike Schmidt’s poster on assessing driver vigilance during monotonous driving. Eike works for DaimlerChrysler and his team used EEG vigilance measures. EEG measures found that participants were negatively affected by long, monotonous driving. Participants subjectively felt better about their state towards the end of the drive but this was not reflected in the measurements. This is a common problem with us humans – we don’t always assess our abilities well. Here’s Eike and his poster:

Paul Green of UMTRI had an excellent poster on inconsistencies and errors in measuring driving performance in simulators and on the road. He recommends procedures to avoid these inconsistencies and errors which are well worth taking to heart. I expect the paper to be posted here soon.

Finally, I have to mention John Sullivan‘s introduction of his poster in the hybrid session. John works at UMTRI and with his colleagues he explored the performance and workload for drivers who used night vision systems. The paper is excellent and the introduction matched the quality of the paper: John started out by listing Google keywords that one might use to find his paper and capped this off with a haiku-style poem.
