Movie goers attending the opening of the Sundance Film festival in Park City witnessed the growing of a new format, virtual reality or VR films. One of the VR films, Hue, uses human interaction to help the character deal with depression.
When you first see Hue, his outline is black, made more distinct because of a plain white background - a colorless space with a desk. Through the use of a headset and a hand controller, the viewer virtually interacts with the cartoon. Hue responds and gradually the room begins to fill with color.
