Effects of using head-up display in automobile context on attention demand and driving performance
Speaker: Jenny 2008/10/1
Introduction Head-up / Head-down display Need to shift attention Time-saving: re-accommodation Increasing workload Shrink effect (S,N. Roscoe, 1987)
Cognitive capture effect: result from inefficient attention (R.S. McCann, et al.)
attention location and the sequence of attention shift
Differences in drivers’ performance between their attention to the HUD and focus on the road
Differences in performance due to the drivers’ attention switch from the HUD to the road
Method
48 subjects into 4 groups 2(driving load, between-subjects) *2(attention
location, within-subject) *2(sequence of attention location, between subjects)
Attention-on-HUD 1st to avoid novelty effect speed limit sign(5s), number(2s),
letter A(20s), read diamond(2s)
Driving Loads
Conclusion During attention-to-HUD, drivers’
enhanced awareness lead better performance
HUD may increase the mental load Best performance: attention shifted to HUD Worst: attention shift from HUD to road
Salient effect Novelty effect: previous training and adaption Drivers’ attention is limited to the road’s right
side, thus it can’t fully simulate real conditions.
