hone in versus home in
To hone something means to sharpen it. It usually refers to a blade, but can also be used metaphorically to mean improving at something, like honing your skills by practicing the clarinet.
Home, when used as a verb and often followed by "in on," means to head towards a destination, like your home — although you can home in on any place.

Covert attention allows you to "home" in on where something is happening without shifting your gaze (not hone).
