1. An interactive simulated-globe display system, comprising:

  • an imaging body, having an external hemispheric surface;

    N image-projecting units, N being a natural number;

    a data processing unit, capable of communicating with the N image-projecting units, and for projecting N images onto the external hemispheric surface of the imaging body through the N image-projecting units, the N images constituting a hemi-globe image of a whole globe image, the data processing unit therein storing a plurality of first instructions and a plurality of position input rules which each corresponds to one of the first instructions;

    an optical pointer, for projecting an indicated spot onto the external hemispheric surface of the imaging body; and

    M image-capturing units, capable of communicating with the data processing unit, wherein the data processing unit detects the N images and the indicated spot projected on the hemispheric surface of the imaging body by the M image-capturing units, determines a spherical coordinate of the indicated spot on the basis of the N images, converts the spherical coordinate of the indicated spot into a plane coordinate, detects a track relative to the plane coordinate of the indicated spot at an interval, judges if the track meets one of the position input rules, and if YES, executes the first instruction corresponding to said one position input rule.
