An Otaku is a person whos upset with Anime/Anime video games/manga,.. Etc
Most of otaku don't express themselves or call themselves otaku ( since people in japanese take otaku as an insult ) because they are shy, sensitive, may or may not suffering from depression, like a person who have living in their house no contact with human interaction
If your friend/family or a person you know is an otaku then please be nice and solf but yet tell them to go out side speak to some people,.. Etc
