'Transparent Texting' will help you avoid collisions while on your phone. You have probably been bumped into by a pedestrian on their phone or you have been in the culprit's position yourself. When this app is released, you will no-longer have to worry about being put in these compromising and embarrassing positions.
Apple just filed for a patent for the technology, which in reality isn't even that complex -- I'm surprised it wasn't thought of sooner. The technology would make the background of the iMessage app a live video feed from the smartphone’s camera. Thus, you can text and still see what is coming up ahead of you.
While this sounds like an excellent, tragedy-avoiding concept, one can't help but wonder how much battery this would use up. Then again, there will probably be an app for that problem too.
