At-home fitness classes are getting the high-tech treatment with Mirror: a full-length LCD display that simulates the experience of being in a workout class. The system looks like a regular mirror, but places you into a live, interactive class via microphones, cameras, and speakers. Basically, “it’s a gateway to a virtual gym.” Virtual/augmented reality is expanding past video games and beyond headsets, and combining tech with Millennials’ passion for health and fitness could help make it mainstream.
