I realize that it is usual to glance at others within your space so that you can assess whether that person might be a potential threat to yourself, but I believe this is not what others do when they look at me. To me it seems people often communicate messages of hostility and aggressiveness towards me,
It's not just so you can screen for potential threats, if you want to look at this evolutionary you also got to consider that we (even Aspies) are social people, we don't stand a chance out there (by ourselves) where there are threats like hunger and lions and so on. Apart from that a large part of our brain is involved in spotting and recognising faces, people like to watch at faces and it stimulates them in all kinds of ways, we are allways looking for potential friends for safety and potential mates for reproducing.
People look at each other all the time, the reason this is difficult for people with ASD is that they have a problem developing theory of mind, you cannot know what they're thinking so some kind of projection is beeing made automatically and depending on your state of mind you'll react emotionally to that (if you feel great and dare to perform like the boy above, you think everyone is smiling at you and you won't interpret anything negatively, and the other way around)
Remember people aren't judging or being aggressive towards you, you look at them too! It's your own projection.
The best (maybe hardest) thing to do is to verify your thoughts if this happens, it will make you feel better about yourself and your social interaction skills. This means that when being looked at, you just go over and say Hi! If this is to hard, just try to smile and you'll be allright after a while!
I hope this was of any help, I'm experiencing some troubles with this myself and I know that if you get to obsessed about it it can be a real pain in the ass.
