BSA = Behavioural Software Assistance

When the virtual world guess what you are trying to do and help you to do it

When you play a card game and the software put the card exactly at the right position, even if you put it 1 mm away.

From Hugh :

Real world signposts are often difficult to read due to angle or darkness. In a VE they can be billboarded so the signpost is always facing the user, no matter where they are.

Example : icon alignment
