Augmented reality is current in "beta" phase as far as technology and application goes. A lot of groundwork has been done by Microsoft and Google with the Holo-lens and Glass respectively. I propose that dell takes advantage of the existing interest of AR technologies, and expands them into large scale environments.
Some of the environments that would be good to see are Zoos, Aquariums and Planetariums where instead of just seeing a docile elephant in a pen, or a limited number of small fish in bowls, and immersive experience where one can stand inches away from a life size Gorilla or Lion. Or enter into a massive water tank and "swim" with life size whales, sharks, and creatures iof the deep that cannot be housed in current aquariums due to varius circumstances (enviornmental/habitat restrictions etc.)
The educational applications are limitless, and if the technologies are implimented into a self contained environment, can lead to an ever changing experience for end users. Every week/month a new "exhibit" could be launched to bring back patrons, leading to a year round income source with drastically reduced overhead expenses vs traditional zoos/aquariums.
Other applications include, but are not limited to: AR-Gaming, AR-Educational programs, AR-Enterprise support applications, AR-client support applications.
