I don't think this is something most "normal" people will do. However, I can see use cases in industry where grabbing a quick photo of some equipment etc might be useful, or in sports where for example cyclists could have a heads up display and use the camera to capture a beautiful view they discover.

As a parent myself, the idea that someone would stop what they are doing to put on goggles to take a photo seems crazy. You would miss the moment. The only reason I use my phone for most photos over a DSLR or Mirrorless is because the phone is right in your pocket and instantly available at all times. I'm pretty sure the newer iPhones already have lidar sensors don't they?

I expect current iPhones can do a good enough job. Lidar + just waving it around + AI make this mainly a software problem.
