Seems like there are apps that can do blueprint/floorplan creation using lidar. Also seems like (from the video, not an expert) Apple is using it within their ML to make the lighting in the photos and videos more crisp/clear. I was honestly interested in the idea of getting one of these devices and offering to realtors the generation of floor plans for their listings. Could cover the cost of the phone (or the iPad) in just a few weekends I would think.
Someday it'll lead to far better video-conferencing, I tend to think. People feel still & far off on the screen, to me, even with good cameras. If we could map people into space, I think we could do a lot to make us feel closer together & more alive on the screen.
low light autofocusing was discussed in the live event. 6x faster focus using true depth sensor.
