Abstract: An image stereo presentation method, comprising steps of: establishing at least one three-dimensional (3D) model corresponding to a physical stereo object; projecting a planar image onto the 3D model at a specific angle, wherein the 3D model has an interface adjoining at least two surfaces in a range of projecting the planar image, and the said two surfaces are not on the same plane; extracting at least two sub-images from the said two surfaces whereby the planar image is projected onto; and forming the said two sub-images on two physical surfaces of the physical stereo object corresponding to the said two surfaces. The image stereo presentation method is capable to present a special visual effect.

Abstract: A pressure sensitive positioning projection screen is provided for displaying a first projected image and providing a coordinate signal of a pressed position. The pressure sensitive positioning projection screen comprises a screen body having a first and a second insulation layers, a plurality of mutually separated and isolated first electrodes arranged along a first direction and configured in the first insulating layer, and a plurality of mutually separated and isolated second electrodes arranged along a second direction and configured in the second insulating layer, wherein the first electrodes are interlaced with the second electrodes for providing the coordinate signal of the pressed position along the first and the second directions.
