Abstract
A scheme for graphical user interface using a polygonal-line-shaped slider that enables a user to intuitively manipulate-and playback spatio-temporal media data such as video data and animation data without deteriorating the temporal continuity of the data in interactive manipulation and playback of the spatio-temporal media data is disclosed. In this scheme, the slider is composed of a polygonal line composed of at least one segment and a coordinate indicator that is moved along the polygonal line. Data corresponding to coordinates specified by the coordinate indicator is entered. The apparatus according to present invention stores the coordinates of vertexes of the polygonal line, stores input coordinates, maps the input coordinates onto a point on the polygonal line, and positions the coordinate indicator at the point.
