We present an audio installation allowing participants to create sounds by looking at different parts of surfaces or objects in various color and texture. By hacking a desktop eye tracker to track gaze points in 3D space, and deploying a webcam to pick up the hue, saturation and brightness of gazed material, we create an experimental musical instrument that can be played by eye gaze. Users have the freedom of choosing different raw materials and explore ways of seeing as a mean of self-expression to create a unique audio experience.

Interactive digital art in the field of performance is emerging as an increasingly important form of artistic expression in Taiwan. Dinner of Luciérnaga is an interdisciplinary project produced by more than ten talented members which include the director, dancer, choreographer, artist, interactive designer, sound designer, iPhone app engineer, image processing designer, stage designer and light designer. The goal of this project is to create new modes of interactive participation between the performers and audience through the use of an innovative iPhone application that links dancer to audience and audience to dancer. The application not only plays a key role in connecting the audience and dancer, but also uses an interesting sound generation application that enhances the spectators' experience. It creates and shares special interactive experiences. Dinner of Luciérnaga is a story about the relationship of light and human in the digital era. It is a stunning performance in visuals and interactive process with focus on new interface that are put into use in authentic environments for validation by audience. In this paper, we will discuss our artistic motivation, the development of the digitally interactive performances, and our process for creating the digitally interactive performance entitled Dinner of Luciérnaga.
