The invention discloses a cursor control method applied to a presentation system. The presentation system comprises a computer, an imaging plane, an optical pointer, a camera, and a projector. The projector is a mobile or built-in projector of the computer for projecting output from the computer onto the imaging plane, wherein the output of the computer comprises an internal cursor generated by the computer. The optical pointer is used for projecting an external cursor onto the imaging plane. The camera is a mobile or built-in camera of the computer for capturing an image of the imaging plane. After capturing the image, a processor of the computer detects both a first position of the external cursor and a second position of the internal cursor corresponding to the image, calculates a shift vector between the first and second positions, and moves the internal cursor based on the shift vector.
A cursor controlling method, an imaging plane being associated with a computer for displaying an output from the computer, an external cursor being projected onto the imaging plane, the output comprising an internal cursor generated by the computer, the method comprising steps of:
A presentation system, comprising:
