As a student, I've had the problem of looking through a textbook searching for that one paragraph of useful information I saw earlier, and not being able to find it. This was my solution. It uses OCR to search for text in real time, and instantly highlights the results, so you don't need to sit around trying to find that one bit of useful text.
Big fan of AR for real uses like this!
Pros:Game-changer. Wish I had this when I was younger
Cons:not yet
i see this as a great mix between AI and AR.
Pros:extremely useful for business and schools, started using it in real life applications
Cons:needs better UI
