Those were big steps in democratizing AR, until then largely the province of high-end developers. Microsoft’s expensive HoloLens headset, for example, is used by architects to walk through a large scale projection of a building to check for safety issues. Headset technology is also still too young to become widespread. HoloLens suffers from a very narrow field-of-view and is heavy to wear for long periods.
