This post not only suggested technical ways for AR to be integrated into spectator experience but also highlight key element that needs to be considered e.g navigation, exposure of educational material. I think gameification is not necessarily the answer as i think augmented reality should be adapted outside of the gaming context. Having said that it is a very logical step to use AR to sustain the entertainment quality within amusement parks.
The flexibility of using an AR interface integrated to physical experience might be a positive and ethical attitude for zoos as it enhances the users interaction with the animal without causing physical disturbance. The AR world whether as a game or just an informative contextualizes the animal whiles obtaining live information and feed-back to the user, making the viewing experience interactive. The constant change within the AR platform gives the user a individual encounter one that react specifically to the animal at that particular state, adding to the traditional experience of pure spectating.
Financially the top 2 income for the London zoo has been from visitor entrance fees and animal trading within zoo through captive breeding. The integration of AR experience may also effect the zoos economically as the virtual systems can be adapt and changes frequently to the mass market .
side note: Investigation into zoology and zoological experience seems to be a treding topic at the moment for architects with the inverted model suggested from BIG to more recent architecctual cometition such as the one below, all trying to re-think a new way for providing a more educational experience in spectating animals
