Conventional systems have tackled to make systems recognize wide varieties of user actions and to install sensing devices with various environmental restrictions. However, since the recognition methods in conventional systems are specialized to their own work, they cannot be applied to other systems and a specialist for activity recognition is required to construct the systems. In addition, conventional systems took a long time to select recognition algorithms and to set the recognition parameters. This means that they cannot have enough flexibility to change the actions to be recognized or to adapt to changing environments. This paper proposes a method of adding interactivity to various surfaces and recognizing the positions and intensities of performed action by using multiple accelerometers. Our method has functions that enable easy settings and maintenance even by beginners in activity recognition. Participants in an experiment on constructing interactive surfaces constructed a system that could recognize two actions at two points in 51 minutes on average. Moreover, we confirmed the effectiveness of our approach with two actual artworks in long-term media-arts exhibitions. ■ キーワード interactive system, media art, accelerometers, recognition method, surface
