Active Light Blocking Glasses: An optical system for protection against photosensitive seizures

Overview

In this project I built and tested a pair of glasses with integrated LCD lenses and light sensor. The glasses use a custom designed frequency analysis algorithm to detect the difference between strobe lights and continuous lighting and react in real-time to block strobe lights through darkening the lenses. Testing was conducted to show the effectiveness of the algorithm in simulated and real-world scenarios. EEG testing of steady state visual evoked potentials was used to confirm the effectiveness of the glasses in blocking harmful stimuli from being received by the brain. The ultimate goal of this research is to build a device to block hazardous light patterns for people with photosensitive epilepsy.
