If AR becomes truly ubiquitous, I hope that signs and signals can most fade away. Imagine walking through a city without street signs or advertisements or stoplights, or walking through an art museum without any labels on the wall, or an airport without screens and arrows pointing you around.
I’m also interested (but also concerned) from a consumer perspective—Amazon etc. will offer Shazaam for literally any object. Like her dress? Buy instantly. That house is tinted green because you qualify for a loan that could purchase it, but the newer one next door is tinted red. Follow the glowing footprints around that corner if you want the slice of cake that person is eating in the park.
Most of all, I want to take a walk in the woods and be able to identify any tree, fungus, flower or bird instantly and beautifully. AR will hopefully let us take intelligent guided tours of almost anywhere. Learn about architecture as you walk to work, trace important sites out the window of an airplane onto the ground below, see a bustling Mayan market animated over what is now a set of rectangular fields.
