Cognitive tunneling in head-up display (HUD) superimposed symbology: Effects of information location  (2001)
Abstract Header
Cognitive tunneling, the inefficient joint processing of superimposed head-up display (HUD) symbology and the out-the-window scene, was found in an earlier study to occur as a result of locating the HUD symbology near (in visual angle) the outside scene information (Foyle, McCann, Sanford & Schwirzke, 1993). They concluded that cognitive tunneling could be eliminated by placing the HUD symbology away from the out-the-window path which was to be followed. That study, however, had experimental confounds which limit that conclusion. The present study eliminates those confounds by controlling HUDbackground contrast, and allowing for the independent assessment of HUD-background complexity and motion. The results indicate that, indeed, cognitive tunneling is eliminated by placing HUD symbology at least 8 deg from the out-the-window scene information.
