Research: Slant Perception

Research was initially carried out as part of my Ph.D thesis. The main aim was to model the visual slant underestimation that had been found in many slant perception experiments. The concept was extended to the problem of landing approach errors by pilots during my time as a National Research Council Associate at NASA Ames Research Center.
