Abstract: A computer (host), which is communicating with an interactive whiteboard projector (client) through a remote desktop connection, launches third-party applications supporting multiple mice (i.e. drawing pens) and provides these applications with virtual mouse device and input event signals for each pen device connected on the projector. The applications will behave as if the host system were configured with multiple installed mice, though no added driver or physical connected hardware is present.

Abstract: A first Gray code technique and a second raster calibration technique can be combined to create a precise mapping between pixel locations of the camera and pixel locations of the projector(s). In one aspect the technique of using the raster calibration images is eliminated by interpolating the projector coordinate information decoded from the Gray code images. In another aspect camera images are processed to reduce errors caused by noise so that text can be displayed without any noticeable misalignment between projectors. In a third aspect, a scale factor is calculated based on the relative height/width of projector regions in the captured calibration images. Calibration images are recalculated using the scale factor to provide greater correspondence between the mapping of a low resolution camera to the high-resolution projectors.

Abstract: A method for correcting a projection from a plurality of digital projectors is provided. The method includes receiving as an input a matrix which maps each pixel to be projected to a captured pixel that includes a row value and a column value and detecting a shift with respect row or column values in the matrix. The method further includes determining attributes of the shift, wherein the attributes include a type for the shift and an overlap length for the shift. A gradient length is determined from the overlap length. A gradient of pixel weightings is generated for each gradient length. The pixel weightings are uniformly sloping and are associated with pixels in the gradient length and neighboring pixels. Intersecting gradients re merged and a list that includes common points and diagonal points is created from the merging process. The method operations may be embodied as code on a computer readable storage medium.
