I am missing a term to describe the mental load which is needed for a human to parse a large menu.
For example I want to switch to google forms:
My eyes need to parse the symbols and/or text to find the right place to click.
I would call it "eye load" but I think this term does not exist.
If you compare this to an autocomplete solution, where a user can enter a text, then an autocomplete solution needs much less "eye load".
The term I am searching should be a sub-type of "cognitive load". That's why "eye load" came to my mind.
Is there a common UX term for this?
