When the user directs to change the view point within a virtual 3-D coordinate space having thereon displayed reduced images as a list of data by successively inputting a view point moving in an arbitrary direction, a trace of the movement of the view point is displayed within the screen. Thus, it has become possible to visualize individual data files in the database and the relationship among each item of the data. Consequently, the user can readily manage the data and retrieve the information he needs.

[ What is claimed is:] [1.]1. A data display method in a virtual 3-D coordinate space having an X axis along a first direction of a 2-D screen, a Y axis along a second direction of said 2-D screen, and a Z axis along a virtual depth direction with respect to said 2-D screen, comprising the steps of:

[ What is claimed is:] [1.]1. A data display method in a virtual 3-D coordinate space having an X axis along a first direction of a 2-D screen, a Y axis along a second direction of said 2-D screen, and a Z axis along a virtual depth direction with respect to said 2-D screen, comprising the steps of:generating a content of data as a reduced image;setting an attribute of each item of said data to each of said X axis and said Z axis within a space;displaying a list of the content of each item of said data on said screen by displaying said reduced image at a position having an X coordinate and a Z coordinate corresponding to a value of the attribute of each item of said data; andsuperimposing a trace of a view point within said space on said reduced image within said screen based on the view point inputted successively in said space, said view point being indicative of which part of said space should be displayed at which angle as an image,each view point which is inputted from a pointing device is stored as history in time series and a trace indicative of the past movement path of the view points is drawn on the screen based on the stored data of the view points,wherein, a dark portion and a bright portion are provided in the trace and the bight portion moves within the trace of the view points in a direction in which the view point moves from the latest one to the older ones.
