Astronaut model created by NightSoundGames.
My initial thoughts on the uses for this technology through the phone is similar to my initial thoughts playing with it last week. The greatest use case is going to be when an application is somewhat passive in enhancing the world for a person. It would accomplish tasks like giving information or being able to see the world in some different lens that shows off other sorts of information. Entertainment applications in AR usually feel somewhat limited in comparison to an information-enhancing application.
The greatest use-case for AR applications is going to be on smart-glasses platforms. The cumbersome activity of having to use a phone to look at something in AR detracts from the uses the platform could have. By incorporating AR applications into glasses, the passive use-cases already discussed above and last week gets the best of both worlds in terms of platform and possibility space.
