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

A method comprising:

• 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.

A non-transitory computer readable storage medium comprising instructions that, when executed, cause a machine to at least:

• determine a first offset at a first calibration point of an input device for calibrating the input device to a display of a computing device, the first offset determined by:
• determining, using a sensor of the input device, first coordinates of a position-encoded film of the display corresponding to a first location of the input device,
• determining, using the sensor of the display, first coordinates of a pixel array of the display corresponding to the first location of the input device;
• and
• calculating the difference between the first coordinates of the position-encoded film and the first coordinates of the pixel array, the difference corresponding to the first offset;
• determine a second offset at a second calibration point for calibrating the input device to the display, the second offset determined by:
• determining, using the sensor of the input device, second coordinates of the position-encoded film of the display corresponding to a second location of the input device,
• determining, using the sensor of the display, second coordinates of the pixel array of the display corresponding to the second location of the input device;
• and
• calculating the difference between the second coordinates of the position-encoded film and the second coordinates of the pixel array, the difference corresponding to the second offset;
• and
• calculate a calibration transformation based on the first offset and the second offset, the calibration transformation to adjust control settings of the input device to control the computing device.
