The benefits associated with the implementation of Head-Up Displays (HUDs) in aircraft have promoted the use of this technology in automobiles. These benefits, however, have been shown to come with concomitant performance costs. Specifically, aviation and motor vehicle research has shown that HUDs produce cognitive tunneling effects whereby an operator’s attention is captured and held by the HUD symbology such that it cannot be directed elsewhere. The cost of cognitive tunneling could be more severe for driving than for flying given that driving environments are typically more densely populated than they are for flying. For this reason, research on the effects of HUD-induced cognitive tunneling in automobiles is important. The current experiment explored the effects of a lane position HUD on driving performance. The results benefits and costs: the HUD improved lane position maintenance, but impaired speed monitoring.
