Calibration of an input device to a display using the input device

Examples disclosed herein involve calibrating an input device to a display using the input device. An example method includes determining first coordinates of a position-encoded film corresponding to a location of an input device relative to the position-encoded film of a display of a computing device based on first position points of the position-encoded film, determining second coordinates of a pixel array corresponding to the location of the input device relative to the pixel array of the display based on a first reference pixel of the display, measuring a first offset between the first coordinates of the position-encoded film and the second coordinates of the pixel array, and calculating a calibration transformation to control the computing device based on the first offset. 本文公开的示例涉及使用输入设备将输入设备校准到显示器。示例性方法方法包括：基于定位编码膜的第定位点来确定与输入设备相对于计算设备的显示器的定位编码膜的位置对应的定位编码膜的第坐标；基于显示器的第参考像素来确定与输入设备相对于显示器的像素阵列的位置对应的像素阵列的第二坐标；测量定位编码膜的第坐标和像素阵列的第二坐标之间的第偏移；以及基于第偏移来计算校准变换以控制计算设备。
