“On August 09, 2012, the US Patent & Trademark Office published a patent application from Apple that reveals that they’re still tinkering with their 2012 granted patent relating to head tracking which was originally published in 2009,” Jack Purcher reports for Patently Apple.

“Apple has added more strength to their patent claims relating to ‘methods’ while dramatically reducing their patent claims relating to ‘systems,'” Purcher reports. “If anything, it shows that Apple is still actively refining their technology which is part of a larger project relating to a future 3D GUI for the desktop and portables.”

Purcher reports, “This is a timely revelation considering that a new patent from RIM illustrates their desire to bring a 3D UI to their future lineup of BlackBerry devices. Yes, the race is on to bring 3D head tracking user interfaces to market and it’ll be interesting to see if Apple will decide to lead or follow on this front.”
