“On April 24, 2014, the US Patent & Trademark Office published a patent application from Apple that reveals a monumental invention relating to an interactive 3D display,” Jack Purcher reports for Patently Apple. “At first I thought it might have been a patent from PrimeSense, but the inventors are Apple engineers. Today’s discovery is one of those patents where you get goose bumps just thinking about what this could mean for the future.”
“According to Apple, an interactive display system may be provided that allows a user to interact with three-dimensional projected images that have been formed in mid-air,” Purcher reports. “The interactive display system may include display structures for producing a primary three-dimensional image. The display structures may include a laser projection system such as one or more infrared laser projectors that project an image into a non-linear optical material such as a non-linear crystal or the display structures may include other types of three-dimensional display technologies.”
