Late last week the US Patent & Trademark Office published a patent application from Apple that revealed yet another take on a possible future virtual keyboard for the iMac and other devices. Apple's first major patent concerning larger virtual keyboards surfaced in 2009. Then in 2011a wave of major virtual keyboard patents surfaced that illustrated the depth of Apple's research in this area. In early January Patently Apple posted a report titled "Apple gets closer to a Virtual Keyboard for the iMac," and later that month we posted a second report titled "Apple Pushes Research into Motion Keyboards for MacBooks." In May, Apple disclosed the invention of an "Advanced Air Feedback System" and last week Apple revealed their fifth major effort into keyless keyboards by disclosing their new piezo-based acoustic and capacitive detection system which includes a very cool glass based keyboard concept that may be a winner.
