As I mentioned in some recent posts, Augmented Reality is moving to the mass market exploiting our smart phones capabilities. However the industry is also moving ahead with specialized devices that can provide more immersive sensation, like AR goggles.
Clearly, these sort of devices are not for everyday use but I can imagine that once in a while they can be used to look at that monument with…new eyes. Also, they may find application in education to get more information on a certain specimen. Studies are going on, in this area, to evaluate the effectiveness provided by immersive augmented reality in studying certain topics.
Of course these devices are only as good as the content that is being provided and overlapped onto the real world. To have a seamless experience requires an understanding of the world around the viewer and a precise mapping of the various objects to align the augmented information on the right spot. There is still a lot of work that needs to be done in the area of image recognition and rendering but the progress has been amazing in these last two years.
