摘要： A system for automatically switching peripheral connectivity between two host devices based on respective connectivity of the hosts. The method may be used where peripherals are usually attached to one host and are automatically switched to a second host when the second host is attached to the system. A USB switching hub may be operable to automatically switch connectivity of the peripheral device(s) from the first host device to the second host device when the second host device is connected to the USB device. This automates the process for the end user when normally all peripherals are attached to one host, and some or all peripherals are shared with a second host when the second host is attached.

摘要： 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.

摘要： 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.
摘要翻译：可以组合第一格雷码技术和第二光栅校准技术以在相机的像素位置和投影仪的像素位置之间创建精确的映射。在一方面，通过内插从格雷码图像解码的投影仪坐标信息来消除使用光栅校准图像的技术。在另一方面，相机图像被处理以减少由噪声引起的误差，使得文本可以在投影机之间没有任何明显的不对准的情况下显示。在第三方面，基于所捕获的校准图像中的投影仪区域的相对高度/宽度来计算比例因子。使用比例因子重新计算校准图像，以便在低分辨率相机与高分辨率投影机的映射之间提供更大的对应关系。

摘要： 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.
