This paper investigates a design for a new form of interactivity with information projected onto a spherical surface. This form of interaction is related to the direct rotation of the spherical surface itself. Traditional methods of computer interaction use a representative format, such as the movement of a mouse representing the motion of a cursor on a flat screen. This representative interaction often becomes less obvious with a three dimensional object, as there is often an exact view position required. The rotational interaction method developed provides a more direct physical connection with the data interaction upon a sphere by mimicking globe style rotational interaction. The authors discuss in detail the design and implementation of the rotation interactivity, including a discussion of the limitations involved.     «
