Information is embedded in the real world with mobile devices. Your laptop and phone analogy doesn't work in this case. That solved a particular problem around mobility. AR solves very little that isn't already solved today.
You can't see or don't appreciate the difference between using a mobile device to consume information vs. an internet-connected personal heads up display that overlays information and objects into your real world? When tech catches up to what we want to do with AR, it's impact on the world will be
bigger than the impact smartphones had.
Imagine being a cop during a routine traffic stop. A quick glance at all of the individuals in the car triggers a query using their faces as inputs that returns and displays relevant information in real time, without the need to ask everyone for their id. The girl in the passengers seat came up as a missing person. The passenger in a backseat has a criminal history that includes murder, so an object appears over his head that indicates you should proceed with extreme caution. Another passenger has racy nudes on Twitter you can flip through.
Imagine being on a golf course with your buddies. You look up at the flag, you know it's distance, the current wind speed and direction, etc. The AR device suggests a club to use, all without fumbling with an app on your phone.
You're sitting in an airport waiting for your flight. You could pull out your iPad and watch a movie,
or... you could initiate "Hologram Entertainment" with your AR device. You look around the room so it can create a model of your environment. Then all of the sudden, lifelike characters appear and put on a personal play, just for you. In the process, they interact with elements in your real world, sitting down in empty seats, walking (and disappearing) behind people, objects, etc.
The possibilities are endless. Use cases ranging the entire spectrum, from the general public to very specialized niche markets.
I haven't been this excited about another developing technology in a long time.
