They found having round icons made people look at the center, rather than the edges and corners. Since the UX relies entirely on where the user is looking, this made it more reliable.
I remember reading it in the HIG when VisionOS came out and everyone was complaining about the shape. I went looking to see if there was a reason, and there was.
That's interesting, but I think this is solvable in better ways. If the VisionOS icon grid doesn't have a voronoi hit map, then IMO they're doing a stupid. There's a _lot_ of space between icons in the grid. It should be plenty of distance to reliably determine that you're looking nearer to the center of a particular one.
Here is what they say:
> In general, give an interactive item a rounded shape. People’s eyes tend to be drawn toward the corners in a shape, making it difficult to keep looking at the shape’s center. The more rounded an item’s shape, the easier it is for people to use their eyes to target it.
The page also talks about leaving enough visual space between elements as well as many other considerations for this type of interface.
