Taking a photo on a cell phone to help write the answer

The child I am homeschooling struggles with spelling. Regardless of how much he tried he would misspell his answer and lose his place.  He decided that taking a picture of the word he needs on a cell phone and then copying it off the phone is easier than looking back and forth a few pages to spell the word.  This has made learning and getting his answers correct more efficient. This unusual tool and idea allows him to be successful when compensating for his learning challenges.  He is also using this idea to find answers to questions involving a map.
