Apple has filed an application with the U.S. Patent & Trademark Office for an optical stylus patent.

Yes, you read that right: Apple wants to patent a stylus, the very thing Steve Jobs famously shunned when he unveiled the original iPhone.

Apple’s idea of the stylus, however, is slightly different from the simple styluses you usually get with tablets today. It’s an optical device that can determine (via a pressure sensor) when it’s in contact with a surface and can capture an image using a built-in camera.
