Abstract:
The method of enhancing the ability of a human observer having a characteristic flicker fusion frequency to resolve the motion and predict the future location of a continuous linearly fast-moving object through the use of a pair of electronically powered optical shutter spectacles, the method consisting of the steps of:a) providing for visual observation through said shutter spectacles by a human observer of a continuously illuminated scene which includes a linearly fast-moving visible object;b) controlling the pair of optical shutter spectacles so that they alternately open to provide the human observer with a view of the linearly fast-moving object and then close to significantly obscure the human observer's view of the linearly fast-moving object; andc) selectively adjusting the shutter frequency to be less than about 125% of the characteristic flicker fusion frequency of the human observer at the brightness perceived by the human observer through the optical shutter spectacles.
