The main feature of this device is a small see-through OLED screen that is mounted on one of the glasses lenses. This allows the user to see through the display while reading text, generated by a computer, then passed along using an Arduino over serial. Any text can be shown, but since that’s not really useful the controlling computer takes pictures with a webcam, then extracts any visible text using OpenCV. Text is then sent to WolframAlpha, which searches the Internet and returns (potentially)useful information, or returns the answer to math problems that it sees.
