Can 'mixed reality' glasses ever go mainstream? Nreal certainly thinks so. The company is pushing ahead with Light, a pair of "ready-to-wear" spectacles that project immersive videos, games and characters into your field of vision. Back at CES, we used the glasses while they were attached to a small, clip-on computing unit called 'Toast' (apparently it looks like a toaster?) Now, the company is showing how the smart glasses can work with a 5G-enabled, Qualcomm Snapdragon 855-powered smartphone instead. That means, in theory, the company can offer a cheaper Light at launch that doesn't require you to carry an extra gadget in your pocket.
