If the text could be made to stay onscreen for longer/until clicked away, this would also make it easier to play games in foreign languages. Most read slower in languages they don't know well. If you're playing with a google translate app, your phone or tablet need a few seconds before being able to translate the text it views on your computer screen.
I guess the same tech could be used to read the writing from the screen out loud.
