Birdhouse began with a mission: to make our roads safer. We have developed our patented device, the EyeAlyzer™. It is the first device which can accurately detect impairment from any drug almost instantly using the same proven eye tests that police officers currently use to screen suspects. The EyeAlyzer™ conducts these eye tests in virtual reality while analyzing the results computationally. The test also produces court-admissible videos which can be analyzed by trained police officers. This is vastly superior to other approaches, since THC concentration and oral fluid, breath, blood, and urine are not correlated to impairment, and cannot accurately confirm recent marijuana or drug usage. Birdhouse's EyeAlyzer™ also tests for multiple drugs at once, by directly measuring impairment, rather than a proxy.
