SENSOR AUTO-CALIBRATION
First Claim
1. A method for generating calibration data, the method comprising:
- detecting temperature of an operating environment for a sensor coupled to a device;
determining that diversity associated with sensor measurement data at or near the temperature is below a threshold; and
in response to determining that the diversity associated with the sensor measurement data at or near the temperature is below the threshold, generating the calibration data for the sensor for the detected temperature using sensor measurement data from another temperature.

Abstract
Aspects of the disclosure relate to computing technologies. In particular, aspects of the disclosure relate to mobile computing device technologies, such as systems, methods, apparatuses, and computer-readable media to improve the calibration data by taking into account the effects of change in temperature on motion sensors. For instance, different levels of error may be associated with a motion sensor at different temperature levels. In one implementation, the sensor measurement data associated with the various orientations at a temperature is used in determining the calibration data for that temperature.
