People usually write a letter, like A, D, etc, on his/her hands, so everytime the person look at it, he/she will remember to do a reality check. I find it kind of useless (again, it's my opnion), because you'll only remember to do a RC, the motion, but you will lack general awareness that is what makes you lucid.
