Abstract: 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.

Abstract: The invention provides a polarizer device. The polarizer device according to the invention is adapted to a polarized light having an electric field direction. In particular, the polarizer device according to the invention enables the polarizer to be automatically adjusted to a proper viewing angle.

Abstract: The invention discloses an apparatus and a method for generating an adaptive stereoscopic image by using a first-eye-viewed image and a second-eye-viewed image, which are captured relative to a scene. The apparatus, according to the invention, overlaps and horizontally shifts the first-eye-viewed image and the second-eye-viewed image until a horizontal difference is substantially at a minimum, and then vertically shifting the first-eye-viewed image and the second-eye-viewed image until a vertical difference is substantially at a minimum. The shifted image is the adaptive stereoscopic image.
