Abstract: Methodology for demonstrating an effect of impairment during driving includes a set of eyewear devices configured to simulate predefined types of cognitive impairment and an activity set structured to provide depictions of roads for driving and associated pre-determined road conditions, the encountering and/or violating of which triggers a real-time feedback provided to the user participating in a driving exercise. The activity set includes a sensor mat underlying the mat with a depiction of roads and equipped with an array of tags activated in cooperation with the sensor scanner that is repositioned by the user along the roads while simulating the driving to provide such feedback. The choice of the exercise (and the corresponding eyewear device) is accompanied by establishing one-to-one correspondence between a particular depiction of roads and a corresponding set of tags of the array via tuning the sensor scanner to recognize only tags from such set of tags.

Abstract: A system for demonstrating an effect of opioid compounds to a user. The system includes an eyewear device including at least one lens having an overlay affixed to at least a portion of the at least one lens, the overlay including a pattern that at least partially obscures a peripheral region of the at least one lens, and the at least one lens including a plurality of independently-controllable regions configured to be switched between different levels of opacity; a processor in communication with the eyewear device; and a memory in communication with the processor having stored thereon a set of instructions which, when executed by the processor, cause the processor to: transmit a plurality of signals to the eyewear device to switch at least one of the plurality of independently-controllable regions of the lens between the different levels of opacity.

Abstract: Methods for simulating effects of impairment caused by recreational consumption of marijuana and/or alcohol using a system including optical filters and various radiant objects. 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.

Abstract: The present invention provides a viewing apparatus for simulating visual impairment. In one embodiment, the apparatus includes a frame defining a viewing area and first and second lenses supported by the frame. The first lens is disposed in a first region of the viewing area. The second lens is disposed in at least a second region of the viewing area. The first and second lenses have different image distortion patterns. In another embodiment, the apparatus may include frame and a lens supported by the frame. The lens includes a first plurality of image distorting features disposed in a first region of the lens; and a second plurality of image distorting features defined in the first region of the lens.
