MultiMedia Performanceにおけるインタラクティブ性と美(「メディアアートにおける『美』と『快』」特集)

抄録

Stage performances are recently made using interaction technologies between performers' body movements and images for stage design, and the interactions occur mainly on the stage. Conventionally, audiences basically see the same scenery from performances on the stage. However, interactions between stage and audiences are important for individualized experiences of audiences. We consequently realized an interactive performing art stage using audiences' eye movements. On performing art stages, audiences make eye movements at various times triggered by body actions of performers and spot lights. If light arrays are flickering fast enough during the eye movements, the audiences can perceive 2D images due to afterimage on the retina. The shapes of the afterimages are different according to their eye movements. The light arrays function not only as illumination, but as a visual display, which can present different 2D images for each audience.
