Integration by the Human Eye: Implications for Warning Signal Design

Abstract: The research of Bloch in the nineteenth century laid the groundwork for the Blondel-Rey Law of visual integration, a law that lies at the heart of warning signal specification methods. That early research suggested that the eye is a perfect integrator up to some temporal limit. Recent vision research casts doubt on this simple model of temporal integration. In this paper we show several examples of data that undermine the simple integration idea, and which require a multiple parallel channel replacement. A nested standards strategy is proposed to accommodate the new insights while retaining earlier systems and methods.
