I know how to determine the distance and direction someone/something is moving by using a sword or other object, but I'm curious if there are any quick and easy methods for getting depth perception information at night?
I've tried using occlusion i.e. telephone poles at a distance, but it just doesn't seem to work very well, it's not really accurate. And raising your hand up to eye level, holding it there and standing still just looks a little weird- what if the person you're facing is coming toward you..
Just wonder about this because in Vancouver it gets dark at about 5pm now and crime is WAY up around here, so it's very important to have as much information about everything around you as possible. But I'd rather not look like a freak about it.
