Apple is expected to unveil sleek headset aimed at thrusting the masses into alternate realities

Apple appears poised to unveil a long-rumored headset that will place its users between the virtual and real world, while also testing the technology trendsetter's ability to popularize new-fangled devices after others failed to capture the public's imagination. 

After years of speculation, the stage is set for the widely anticipated announcement to be made Monday at Apple's annual developers conference in a Cupertino, California, theater named after the company's late co-founder Steve Jobs. Apple is also likely to use the event to show off its latest Mac computer, preview the next operating system for the iPhone and discuss its strategy for artificial intelligence.  

But the star of the show is expected to be a pair of goggles — perhaps called “Reality Pro,” according to media leaks — that could become another milestone in Apple's lore of releasing game-changing technology, even though the company hasn't always been the first to try its hand at making a particular device. 

Apple's lineage of breakthroughs date back to a bow-tied Jobs peddling the first Mac in 1984 —a tradition that continued with the iPod in 2001, the iPhone in 2007, the iPad in 2010, the Apple Watch in 2014 and its AirPods in 2016.
