EyeCon -- a motion sensing tool for creating interactive dance, music and video projections

EyeCon is a video-based motion sensing system which allows performers to generate or control music and projected images through their movements and gestures in space. It was developed Frieder Weiß as an applicationdriven project of the Palindrome inter-media performance group and is thus more a tool for artists than for researchers. EyeCon does, however, allow motion sensing according to a variety of movement parameters and lends itself to experimentation with media mapping. Unique and largely unexplored problems face composers, graphic artists and choreographers as they collaborate on interactive performance works, not the least of which is settling on schemes for mapping the various parameters of human movement to those within the world of sound and image. Among the myriad mapping alternatives, good design choices are paramount to creating effective interactive performance works. The authors have made progress in understanding the special issues involved and are devising strategies for these choices.
