Abstract

System for simulating effects of impairment caused by recreational consumption of marijuana. The system includes i) an optical filter having a pre-defined spectral pass-band and a non-diffractive spatial pattern configured to deviate a beam of light incident onto the filter, and, optionally, ii) radiant objects at least one of which delivers light in a spectral band corresponding to color that is complementary to the color defined by the pass-band of the optical filter. Method for demonstration and analysis of impairment of cognitive function caused by using the system to affect the vision of the user.

Claim(s)

1. A system for simulating cognitive impairment of a user, the system comprising: a pair of goggles containing: a first optical filter element having first and second spatial dimensions and an optical filtering function with a spectral pass-band around a first wavelength; and a second optical filter element having the first and second spatial dimensions and the optical filtering function; wherein said optical filtering function is invariable with respect to a position across the first optical filter and across the second optical filter; a first radiant object configured to reflect light at a second wavelength, wherein the first and second optical filter elements are configured to block light at the second wavelength; a second radiant object configured to reflect light at a third wavelength within the spectral pass-band, wherein a color defined by the third wavelength is complementary to a color defined by the second wavelength; a first light-generating source configured to generate light at a fourth wavelength, wherein a color defined by the fourth wavelength is complementary to a color defined by at least one wavelength within the spectral pass-band; a second light-generating source configured to generate light at a fifth wavelength, wherein the fifth wavelength defines a color that is complementary to a color defined by the at least one wavelength outside the spectral pass-band; and a substrate bearing a graphic representation of a maze; wherein at least a first portion of the graphic representation is configured to reflect light at a first set of wavelengths, wherein wavelengths from the first set of wavelengths define corresponding colors that are complementary to at least a first color, the first color being a color complementary to a color defined by a wavelength within the spectral pass-band; and wherein at least a second portion of the graphic representation is configured to reflect light at a second set of wavelengths, wherein wavelengths from the second set of wavelengths define corresponding colors that are complementary to at least a second color, the second color being a color complementary to a color defined by a wavelength outside the spectral pass-band.;
16. A system for simulating cognitive impairment of a user, the system comprising a first optical filter element having an optical filtering function with a spectral pass-band around a first wavelength, wherein said optical filtering function is present at every point across the first and second dimensions of said first optical filter element, wherein the first optical filter element is defined by: i) the optical filtering function that is spatially-invariable within bounds of said first optical filter element, and ii) a spatial pattern at a body of the first optical filter element, the pattern defining different phase delays for first and second collimated light beams that are incident normally at the first optical filter element at different points and propagate through the first optical filter element, a period of the pattern chosen so at to not produce an optical diffraction effect when irradiated with visible light; the system configured as goggles that cause the cognitive impairment of the user when worn by the user to observe an environment, said first optical filter configured as a first lens of said goggles.
