If you had updated lately your google mobile app, you can now solve sudoku with it.
Just take a photo of a sudoku game and press the Solve button :)
Sometimes I don’t get the solve button. And sometimes it solves another problem (like in the movie).
In any case if I take a photo from a website, the google app find out from which webiste the photo was taken :)
Amazing.
We are now waiting for the next step of taking a picture of a man in the street and find out all the details about him – His friends (from facebook), his current job (linkedin), etc. The technology is there.
