This paper describes the integration of a full-body interactive system for its use in live coding performances. The system has an interactive mat of grid layout, which is located on the floor and serves as a guide for the user to move within its 17 areas in which it is divided. The body gestures made by the user are mapped to modify the execution of the algorithms that generate the sounds and the visuals in real time. Thus, the audience can participate in the improvisation through full-body interactions and without having programming knowledge. The system allows the live coders to manage the parameters manipulated by the user during the interactive experience. It was noted that users recognize the interactive mat as a space of interaction with the system and also that users move intuitively on the mat. In addition, we found that the users recognize the feedback of their body gestures, by observing the change in the outcomes of the visuals and sounds, during a live coding performance.
