Abstract or Description

“The Ball in The Hole” is an interactive video installation, running on GPL homemade software, which uses the principle of tele-presence.
Two rooms are showing a projected mirror, where the user can see and recognise himself. On the floor there is a spiral, containing a luminescent ball. When the user grabs the ball, spontaneously attempting to play with it, the projected mirror will start erasing, showing the other room. The ball, as an interface, will act on the video as an eraser on a pencil drawing. The two rooms / spaces are symmetrical.

After the complete erasure of the image, the mirror will show the remote room only. At this point the game flips: the ball, rubber and pencil at the same time, gets the capability to erase the other person / space / video. Therefore this deletion of the Otherness corresponds to the redrawing of the Self. You draw as much as you erase, in direct proportion.

The process continues endlessly rendering the installation a social happening where the user becomes the main character of an improvised performance.
