Let me answer your question by discussing several different contexts
in which invisibility  occurs.
In a social context, invisibility can be implemented in the following
1. "Cocooning" is the act of staying at home without participating in
social life, relying purely on stimuli of modern entertainment (like
the TV set). Thus, one becomes invisible to society. Often, newspapers
feature a story where a person is "rediscovered" only after their
corpse emits a heavy stench, forcing others to call the police to have
the door opened.
"Cocooning - The need to protect oneself from the harsh, unpredictable
realities of the outside world"
2. "Conformance" -- also, "compliance" and "political correctness" --
within a social context often results in blending in with the (social)
decor in ways that other people do not recognize one as an individual.
(On a side note, there's a cartoon picturing a depressed fellow on the
couch telling his shrink, "Nobody seems to take notice of me", and we
can see the psychiatrist saying, "Next please".)
3. "Anonymity" can be achieved by faking a passport, wearing
sunglasses and dark hat, and by taking the back-entrance to a given
building, resulting in invisibility. Also see the following book:
How to Be Invisible (by J.J. Luna)
In mythology, fantasy and fairy tales, like J.R.R. Tolkien's "Lord of
the Rings" , the task of becoming invisible is most often solved by
the use of either a magic item such as a ring, robe, and necklace, or
by a magic spell. (A trained wizard can not only use his magic wand to
turn himself invisible, but also other people and objects in the room,
to the amusement of innocent by-standers.)
Mercury - The Invisible god
"In Greek mythology there was a special helmet rendering invisible the
person or god wearing the helmet. This helmet of invisibility is most
often linked with the underworld god Hades (Pluto), however (...) this
helmet of invisibility rightly belonged [to] the messenger god Hermes
(known to the Romans as Mercury). Worn over the head, Hermes' helmet
signifies hidden thoughts and secrets. Much of the time Hermes enjoys
hanging out unnoticed in the background."
In Science-Fiction, advanced technology brings invisibility. These are
mostly stealth devices like hi-tech costumes, or complex chemical
experiments, or stretches of physical boundaries. The most well-known
horror classic in this genre is H.G. Well's "The Invisible Man", also
brought to the big screen:

"As the brilliant scientist who discovers the secret of invisibility,
[Claude] Rains steps into the film wrapped up like a mummy behind a
layer of bandages and blanketed in heavy clothes. When he removes his
garments, there's nothing underneath, a simple but effective bit of
1930s movie magic"
The agent with the license to kill, James Bond 007, lately uses cars
to fake his disappearance or drive by unnoticed. This can be seen in
the 2002 action movie "Die Another Day".

Camouflage is the art of copying environmental colors and patterns so
that one will not be seen by an enemy animal (in biological context)
or soldier (in the context of battlefield).
Advanced trickery and deceit is closely related and often used by
magicians, as well as spies, ninjas, and soldiers. Please see:

And the most simplest trick is a mother's Peek-a-boo game -- though
the target audience this trick can be executed on is limited to
younger members of society. When, in front of her child, she covers
her face with a towel, the little one will think she's gone, only to
break into bursts of dazzled giggle when mother returns from behind
the cover. 
Game Psychology: Part 1
"The games show a clear differentiation of participant roles, and a
mutual respect by both parties for the constitution of the game. Each
repetition of the game rests on the same sequence of moves, though
certain variation in the execution of each move is permitted. What
makes a good game of Peek-a-boo is the shared expectations concerning
what happens next, and a willingness to conform upon 'agreed'
In a virtual world -- like a video game -- one can become invisible
due to so-called Power-Ups; that is, special potions, lotions, or
machinery hidden within the world. And those who like to cheat might
also enter a secret code to achieve invisibility, e.g.:
Grand Theft Auto 2

Psychology of Cyberspace - The Online Disinhibition Effect:
You Can't See Me (invisibility)
"In many online environments other people cannot see you. As you
browse through web sites, message boards, and even some chat rooms,
people may not even know you are there at all (...)
This power to be concealed overlaps with anonymity, because anonymity
is the concealment of identity. But there are some important
differences. In text communication such as e-mail, chat, and instant
messaging, others may know a great deal about who you are. However,
they still can't see or hear you - and you can't see or hear them."
I hope this helps!
