In the movie Spider-Man: Far from Home, Peter Parker gets a pair of glasses that give him access to a wide range of useful information. In true sci-fi fashion, they are nearly indistinguishable from normal corrective glasses, yet incredibly powerful. YouTuber JLaservideo decided to construct his own version of this wearable tech, and while they’re not quite as subtle as the ones in film, they do have some impressive abilities.
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.
The glasses require a number of wires that are attached to a notebook computer to operate, so it’s still a long way from Spider-Man’s functionality. However, as seen toward the end of the video, it can still be used (literally) on the road, and JLaservideo demonstrates this capability by letting it analyze a stop sign for him!
