Design and Prototyping of Computational Sunglasses for Autism Spectrum Disorders

We design the computational sunglasses for individuals with autism spectrum disorders (ASDs) to alleviate the atypical visual perceptions caused by their unique light sensitivities. With the proposed system, a scene camera is used for ambient illuminance detection, and an appropriate occlusion pattern is calculated in real-time then displayed on a spatial light modulator (SLM) to modulate the contrast of the incoming scene. Based on a simple contrast adjustment algorithm that avoids overexposure and underexposure, our bench-top prototype demonstrates better scene contrast successfully.
