Gesture is a form of non-verbal communication using various body parts, mostly hand and face. It is the oldest method of communication used by humans becoming essential. By existing for a long time, the use of gestures is natural in interaction between humans, which means that its use does not cause awkwardness between people. Since the rise of technologies such as the computer, scientists have been looking for the best ways to enable the interaction of man with these machines. The gestures are presented as an valuable option because they are common to human beings and simple to be realized. Several devices began to be developed in order to be able to identify sets of gestures made by people and enabling, thus, new interactions. These sets of gestures tend to be generated by scientists themselves, by test users or even movies, are sometimes used as a means to inspire researchers. However, it is important to note that do not necessarily gestures are the best alternative to human-computer interaction. Science fiction movies (sci-fi) are one of the sources from which researchers extract ideas for new ways of interaction. The fact that they are being presented and followed around the world makes interactions found in sci-fi movies more accessible and easy to be accepted by the final public. Movies like Minority Report (1995) inspired and inspire many researchers in the search for a perfect interaction system, as the one shown in the film. Movies are a tool used by film producers to predict their own future visions that are harvested by researchers to be tested and, if produce good results, introduced in the market. By owning several sources of appearance, the hand gestures used in human-machine interactions, generally do not have a certain pattern. Each researcher and film producer gives the gesture interpretation what they believe to be the most appropriate. Thus, it is not difficult to find identical hand gestures generating distinct interactions. In this context, the work presented in this dissertation aims to collect and expose aspects to hand gestures found in science fiction films and papers published in scientific databases. For this, questions such as "Where does the gesture come from?", "What does it mean?", "How is it done?" and “What is it good for?” are answered through mappings that were performed using found hand gestures and sorting them into categories able to respond how hand gestures are being used either by researchers or by film producers.
