Participatory Body Instruments Participatory Body Instruments use gesture and movement to alter the “music” of images and sounds projected onto a space or displayed on a screen. Participant movement captured by sensors alters imagery and sound. Participants play with the intruments in their own way while also responding to the gestural style of other players. There are two sets of sensors, one set for each player. A set of sensors includes a flex resistor, a photocell resistor, and a potentiometer. By bending and moving her arm and by covering and uncovering the photocell, the player alters the “music” of the instrument; by turning the potentiometer, she alters the type or genre of “music.” Each player controls characters and sounds on a portion of the screen. The first player controls the top half of the screen; the second player controls the bottom half of the screen. When a player moves her arm, the animal characters on the screen move back and forth; covering and uncovering the photosensor also create animal movement. There are three genres of “music” a player can control. This allows for potential moments of collage–players simultaneously manipulating images and sounds in different genres. Three genres of animation and sound: painterly, cartoony, and mosaic-inspired pixel-shapes. Mixing of animation and sound genres based on participants' selections.
