Re: sensing smartphone
>What are some of the most intriguing applications that you expect from this sort of tech?
Two-player games where real-world position and obstacles matter. eg: you'll be able to shoot at one another virtually and calculate hits and misses accurately.
Navigation apps for enclosed spaces that are precise.
The ability to place 3D overlays on specific objects. eg: instantly replace a person or object in an image with something else. eg: super-easy photo editing.
Inventory applications: Take a picture, identify products on shelves, see how many more are needed.
Warning apps for bikers...put your phone or a wireless camera on your helmet and track nearby obstacles.
The list goes on and on. Depth information makes so much possible.
