The workshop gives a practical introduction into artistic uses of video motion sensing technologies. Frieder Weiss develops his own software for stage use, which mostly uses video cameras to analyse and visualize the movement of the dancers. The workshop will introduce Eyecon and Kalypso software. Eyecon links physical movement spaces with computer generated sound environments. By drawing virtual zones on screen you enable the mapping of human movement to real time sound and visual media. Kalypso software allows visual effects based on body outlines; similar to what was created for Chunky Move's Glow. In the workshop participants will be able to understand and learn the basics of the software, set up a customized interactive environment and get a chance to move and try out the experience. Experienced computer users are invited to attach systems which they are using: we will be able to interface to systems like MaxMsp, Flash, Isadora etc. A discussion about artistic implications and results will round up the workshop. Limited to 15 participants. Weiss will also be giving a talk about his participation in and observations of the ‘dance tech’ genre over the last 15 years on Wednesday December 3rd.
