Children's and parents' perception of full-body interaction and violence in a martial arts game

摘要

This paper presents a study of children playing a full-body-interactive mixed-reality martial arts game. The user interface of the game is multi-modal and unencumbered -- any number of simultaneous players can fight collaboratively against the virtual enemies using body movements and voice.The contribution of the paper is two-fold. Firstly, based on our observations, interviews, and an earlier study of the game with martial artists, we discuss the challenges of designing full-body exertion interfaces for children. Secondly, there are no previous studies of the combined effects of full-body interaction and violence, although interaction design for children and the effects of media violence are active fields of research. In this paper we propose that when assessing the level of violence in interactive media such as games, both user input and system output should be considered. The realism of user's actions and the audiovisual output both contribute to the overall realism of the user experience.
