Abstract

In some examples, a stylus determines that an end cap was removed from an end of the stylus and notifies a computing device. In response, the computing device initiates a calibration process that includes displaying a pattern on a first display device of the computing device. The stylus gathers first data when the end of the stylus traces the pattern and sends the first data to the computing device. The computing device stops displaying the pattern on the first display device and begins displaying the pattern on a second display device of the computing device. The stylus gathers second data when the end of the stylus traces the pattern and sends the second data to the computing device. The computing device uses the first data and the second data to calibrate the first display device and the second display device to reduce perceived color and intensity differences.

Dependent claims

A method comprising:

receiving, by a microcontroller unit of a stylus having a tip and an end, sensor data from a Hall effect sensor that is included in the stylus;
determining, by the microcontroller unit and based on the sensor data, that an end cap that includes magnet has been removed from the end of the stylus;
enabling, by the microcontroller unit, one or more light sensors located in the end of the stylus;
collecting, by the microcontroller unit, first data from the one or more light sensors when the stylus is placed over a first display device of a computing device;
sending, by the microcontroller unit, the first data to the computing device;
collecting, by the microcontroller unit, second data from the one or more light sensors when the stylus is placed over a second display device of the computing device;
and
sending, by the microcontroller unit, the second data to the computing device;
wherein the first data and the second data are used by the computing device to perform a color adjustment to at least one of the first display device or the second display device to reduce a perceived color difference between the first display device and the second display device.
