Head's-Up-Display. This is something I wish I had. Imagine being able to instantly annotate something in your mind
and have it appear in your field
, available for your perusal
at any time, and static
. This would come in very handy when organizing your thought
s, trying to remember a phone number
, coming up with Things To Do List
s, and so on.
Actually, we already have something sort of like a mental HUD; we can visualize things in our mind quite easily. However, it's not static, and if you visualize a phone number and then become distracted doing something else, you are likely to forget it.
A good example of a mental HUD is the one that the Terminator has in the movies of the same name.
