Best known for discovering security flaws in online systems, Dan Kaminsky has recently announced the development and release of a smartphone app to help with color blindness. DanKam takes the colors that cause viewing problems and applies filters to make them visible. The system is currently optimized for the most common form of color vision deficiency, although users are encouraged to customize and tweak the augmented reality app to try and find settings that work best for them.
