In theater activities that are currently actively carried out, many of the theater organizations has been working with borrowed practice space and the actors have done theater activities while having another job. Therefore, the amount of practice time gathered a director and actors is limited. However, in order to carry out the practice with awareness of production and other actors, director and all actors must gather same place and make a practice based on the coaching of director. In this paper, we propose “Digital-Script” and theater practice support system. Digital-Script contains information that are important for production. Theatrical practice support system enables actors to practice performance in the situation that director or a part of actors cannot gather by using Digital Script. We evaluated the system by comparing the errors of subjects’ performance who used theatrical practice support system and script visualization application.
