Human movement on camera in a public space creates the visual input, followed by writing software that creates the visual output. This is basically the process that Camille Utterback uses to then integrate forms, created by ink and pencil drawings, with human movement. These forms appear and disappear on a screen based on the movements made by an audience. Once this happens an almost circular process of movement, forms and again movement is created. To keep this process going the audience has to embrace vulnerability in order to visualize the movement on the screen, trying to maintain control. All of this is supported by technology what leads to the question where we can put the matter of control.
