The action or process of calibrating an instrument or experimental.
This device is to allow the viewer to be able to experiment and operate what they see. The device has a rotational feel. Where you are able to control the behavior and interaction connected to the device. The hand actions become intuitive, which the experience is more compelling for the user.
The rotation of the hands becomes an unconscious movement/thought so they are able to focus on the actual piece itself. As the audience is rotating the device they are controlling the change of colors on a screen. Which creates the ability for the audience to have them have an emotional feel on each color and focus on the connection between the colors overlapping and transitioning into another color.
