I don't really care about labels, but I have found in the past that a lot of the things that help Aspies who want to act more NT help me, too - such as a computer program I found once that teaches recognition of facial expression.
I don't know how you get taught proper eye contact. Probably through positive reinforcement when you're doing it right, and feedback about how to do it better. But I never tried it...I thought I was doing alright...
I agree with hypocritex; most ppl don't care if you're doing it right, unless you're just meeting them.
