“Apple was well ahead of the pack when they were first granted a patent for a video headset display back in 2009,” Jack Purcher reports for Patently Apple. “Back then, there was no Google Glass or Sony video headset. Apple’s original patent was filed in 2006 which was in and around the time that Apple was working on Project Purple which was the code name for the iPhone. Since that time Apple has been working on other aspects or features for a possible future headset, with one them being the addition of telephony.”

“With Apple recently acquiring PrimeSense who has a patent regarding a headset on record, there appears to be new interest in advancing Apple’s personal display system,” Purcher reports. “With PrimeSense making Microsoft’s Kinect system a reality and their technology being at the heart of new 3D camera phones like Google’s Project Tango coming to market this year, the PrimeSense team may be able to breathe new life into Apple’s video headset project.”

Purcher reports, “Today, the US Patent & Trademark Office published a patent application from Apple that reveals that they’re advancing one of their video headset patents by adding new and improved patent claims to strengthen and update their invention.”
