DOI: 10.1145/1146816.1146823This article is a description of MYSQ, an entertainment system that allows users to create original music video clips (ex:MTV) and share the resulting video with friends via cellular phones. The original movie is original because it is generated using video of the user, combined with video effects that use the user's dance movements as parameters. The MYSQ concept is communication through the process as well as the product of content creation. The MYSQ system can be characterized as: simple operation, multilayered interaction, collaboration, the conversion from player experience to content, and making experience transferable by converting it to media form. This article will then analyze the system with game flow, based on Csikszentmihalyi's FLOW theory, to evaluate the system's entertainment value as a game, and the effectiveness of the characteristics above.
