Abstract
A method of calibrating a first inertial measurement unit (IMU) of a mobile electronic device inserted in a headset includes, when a controller having a second IMU is mounted to the headset: performing a calibration procedure to generate first calibration data for the first IMU and second calibration data for the second IMU; receiving the second calibration data from the controller; determining a difference between the first calibration data and the second calibration data received from the controller; and calibrating the first IMU in accordance with the difference between the first calibration data and the second calibration data. The method further includes, when the controller has been removed from the headset after performing the calibrating, executing a virtual-reality application, comprising generating images based in part on motion data generated by the calibrated first IMU and displaying the images. The motion data corresponds to motions of the mobile electronic device.
