Object perception system and method
A system and method for object perception is provided comprising one or more sensors for sensing and delivering to a processor environmental data inputs with reference to an object viewing point. The processor uses the data inputs to determine and select light outputs to be emitted from one or more displays. The light outputs are modulated to comprise one or more wavelengths of light that elicit one or more targeted vision responses in order to facilitate object perception from the object viewing point. The light outputs can be modulated according to how the environmental parameters sensed change over time (e.g light conditions). Light outputs may include the emission of equiluminance based wavelengths of light and peak sensitivity wavelengths of light to elicit peripheral and foveal vision responses, respectively.

wherein the light outputs emitted are modulated to comprise one or more wavelengths of light selected by the processor to elicit one or more targeted vision responses from a viewer, and thereby assist the viewer to perceive the object in the environment from a given viewing point of the object situated within a scenery of the environment, as the one or more environmental parameters sensed change over time.
