• This specific finding is minor, but its implications are not IMHO. From the article it appears the researchers consider this a discovery in effect.

    If consumer hardware is already capable (in many settings) of reproducing what were formerly research-level and industry-grade techniques, it may be a transformation in more areas of technology than would be obvious. I am very curious to see if there will be further findings in this area.

    • This is a very natural progression of technologies that escape industry/defense to get into the consumer's hand.
    • The military/LEO is probably already envisioning a Daredevil like helmet with augmented-reality lenses that overlay non-line-of-sight threats in real time.
      • Didn't we already have a video of that? I don't remember the data sources used to generate the overlay, however. Was it multiple solders' helmets sharing their data, and/or perhaps even a drone from above?
  • Smartphone grade lidar == FaceID ?
    • depends on what phone you have but LIDAR sensors are used for more than just faceID
  • So this only works if you have walls opposite of this corner?
    • It seems to require a lidar reflective object. Likely more generally, the effectiveness lowers the less objects there are to bounce and return signal.

      It could probably work with less accuracy/resolution against visible vehicles in the opposite lane, a hedgerow, postal box, pedestrian carrying a visible laptop and possibly synthesize all of these to improve its guess.

    • The video thumbnail implies bouncing off the ground, not a wall. Not sure how the geometry works out for that
  • Why not just place a mirror at 45 degrees in the corner? That way you don't need the lidar but you can just look around the corner? It would also work better with the lidar.
