Infocom used the term feelie to refer to the extra content included with the boxed versions of their interactive fiction computer games. Feelies differed from game to game and were of the same theme as the game they came packaged with. For example, Wishbringer, a fantasy game with magic, came with a "Magick glowing stone." These extra objects and documents sometimes served as a form of copy protection, as several games were impossible to solve without information found in their feelies.
Some of Infocom's games and their feelies are listed below:
The word feelie has also been applied in Aldous Huxley's Brave New World, as a form of motion picture that provides the sensation of touch in addition to sight and sound. The word suggests a logical extension to the moving picture ("movie") and the talking picture ("talkie"), and suggests an entertainment form with an incredible level of sensation but with minimal substance.
