The simple cut-outs are designed to avoid walkers crashing into one another. There are many applications, from underground public transit tunnels, to hallway corners, to street corners.
Essentially, urban planners need to take a slice out of their concrete corner about 5-6 feet from the floor/ground.
You could fill this with glass, put glass on the exterior (in an L-shape), or leave it empty.
But the point is -- you should be able to see someone coming. Mirrors are used in some places, but cut-outs would be easier.

I like the idea, but I forsee a problem with load-bearing walls. |
|
| |
I find that carrying a pitchfork with me -- and sticking it around the corner just before I turn -- works quite well. |
|
| |
Construction-wise it seems like it would be easier to use 2 45 degree corners set back an appropriate distance. How deep does the cutout need to be? I suppose that depends on how fast people walk, how fast they react and how rapidly their masses can be decelerated. |

I guess the easiest explanation is to envision the corner of a wall being constructed out of triangular layers (like flat Lego pieces). You take a few out near the average person's eye level so that a 3-5" gap is created. |

Q: Well, then why not just cut the wall off and make a rounded corner? |
|
| |
A: Well, I don't know. It's half-baked, that's why it's here. Anyway, you could make it a rather large triangle, like a couple feet from the corner on each side, and put a steel rod or something at the corner to assuage load-bearing fears (which are legitimate). |
|
| |
Actually, you could use a steel gridwork filled with those 'decorative' glass blocks without too much structural risk, I think... |

Just have virtual cut-outs. In public places, put plexiglas protected giant monitors on the walls of high-traffic corners (right where you'd like the cut-outs to be) which show the image from around the corner, using an adjacent ceiling-hung camera. |
|
| |
why not have a 1" square plexiglass rod that adheres to the corner, then you can see rough images of movement around the forner warning you. |
|
| |
or just approach corners at a reasonable velocity and dont sneak around the corner like an Office Ninja, keep a respectable distance of 3-5 feet. |
|
| |
or how about electronic eyes at foot level that shows a green light or red light to those around the corner letting them know someone is coming |
