AlphaFold, developed by DeepMind (Google), is an AI system that predicts the three-dimensional structure of proteins from their amino acid sequence with revolutionary accuracy. In 2020, AlphaFold 2 achieved protein structure prediction accuracy that rivals experimental methods, solving a 50-year-old grand challenge in biology. AlphaFold has since predicted the structures of over 200 million proteins—essentially all known proteins—and made these structures freely available through the AlphaFold Protein Structure Database. This has had a profound impact on drug discovery, vaccine development, enzyme engineering, and fundamental biological research worldwide.

Be My Eyes is a mobile app that connects blind and low-vision users with sighted volunteers for live video assistance, now enhanced with Be My AI—a GPT-4 Vision powered tool that instantly describes images, reads documents, identifies products, and provides detailed visual context without waiting for a volunteer. The AI feature can describe complex scenes, read handwritten text, identify objects in a refrigerator, navigate unfamiliar environments, and provide fashion advice—all through the phone camera in real time. Be My Eyes' AI has transformed the app from a volunteer-dependent service to an always-available AI assistant for the visually impaired community worldwide.

Seeing AI is a free Microsoft app for iOS and Android that uses AI to narrate the visual world for people who are blind or have low vision, offering multiple channels for different tasks including reading short text instantly, reading documents with layout preservation, describing scenes and people, identifying products by barcode, recognizing currency, and reading handwriting. Its People channel can recognize and remember individuals' faces, announcing them by name when they appear in camera view—enabling more independent social interactions. Seeing AI was developed in partnership with the blind community and is continually updated with new AI capabilities from Microsoft's computer vision research.

NaviLens is an AI-powered accessibility technology that uses a specialized optical code (the NaviLens Code) that can be read by smartphones from up to 12 meters away, enabling blind and low-vision users to get instant location and navigation information in public spaces like transit stations, airports, and campuses. Unlike traditional QR codes that require precise alignment, NaviLens codes are detectable at wide angles and distances, and the app announces contextual information—platform numbers, gate directions, food labels—as users move through space. NaviLens is deployed across Barcelona Metro, Los Angeles Metro, Kellogg's packaging, and hundreds of other real-world installations.
