There’s actually an emerging category of virtual experiences that allow a user to experience digital objects as if they were real, without the need for a wraparound headset. There hasn’t been as much chatter about it, but “non-enveloping” VR could be one of the biggest, most important parts of this new wave of digital-analog world interfaces.”
