“Apple’s first invention relating to a 3D holographic display was back in 2008,” Jack Purcher reports for Patently Apple.
“Today the US Patent and Trademark Office officially published Apple’s second granted patent in this field but takes it to a whole new level aiming for an interactive holographic display for Macs and iDevices like an iPhone or iPad,” Purcher reports. “Apple notes in their granted patent that ‘The mobile telephone, media player and personal computer can provide a three-dimensional viewing and interacting experience, without the requirement of a reflective medium or wearing 3D glasses. Accordingly, a truly unobtrusive interactive three-dimensional holographic display can be provided.'”
