Abstract

A method and system for generating calibrated data are described herein. The method includes detecting a computing device is in a first position and detecting axis data that corresponds to a sensor of the computing device in the first position. The method also includes using the axis data to modify sensor data to produce calibrated data. Furthermore, the method includes sending the calibrated data to an operating system.
