Awesome post! Thanks for writing in two languages--so impressive and inclusive. Regarding the actual topic at hand, have you heard about these electronic glasses for the blind from OrCam? They're an assistive technology for visually impaired that helps blind and partially sighted people with everyday tasks, such as reading, facial recognition and more. Definitely recommend you take a look and explore all the technology out there for improving the daily lifestyle of the blind/visually impaired as this market continues to grow.
