It’s a simple triangulation issue. Shoot, missiles are programmed every day for this. Our brain is far superior to missile guidance systems which key on radar or thermal or visual signatures/profiles, etc. Pretty simple....we acquire the ‘target’ visually and our brain quickly plots an intercept course, supplying the proper signals to our limbs, etc. to respond accordingly.
Actually, they don't plot an intercept course ... they actively minimize a deviation from an intercept point ... if they lose lock, they miss. An outfielder can lose lock and still catch. There are several mechanisms going on in our brains, which these folks are trying to isolate.
Our brain is far superior to missile guidance systems
In many ways ... the focus of this research seems to be understanding that superiority, in order to design better guidance, tracking, and intercept machines.
