Motion Sensor Virtual sensor, combines gyro + compass + accelerometer § Motion Sensor vs. gyro or compass or accelerometer § More accurate § Faster response times § Comparatively low drift § Can disambiguate motion types § Has fall-back if gyro is not available Always prefer Motion Sensor when available § 14 Windows Phone Microsoft Corporation.

Motion API if (Motion. Is. Supported) { _sensor = new Motion(); _sensor. Current. Value. Changed += new Event. Handler<Sensor. Reading. Event. Args<Motion. Reading>> (sensor_Current. Value.

Motion Sensor Adapts to Devices Accelerometer Compass Gyro Motion Yes Yes Full Yes No Degraded Yes No Yes Unsupported Yes No No Unsupported Degraded modes have lower quality approximations § When Motion. Is. Supported is false, apps should use accelerometer or other input and control mechanisms § 16 Windows Phone Microsoft Corporation.

Sensor Calibration Event is fired when calibration is needed § Both Compass and Motion sensors need user calibration § Apps should handle it § Provide UI asking user to move device through a full range of orientations § Not handling will cause inaccurate readings § We are considering providing copy & paste solution § 17 Windows Phone Microsoft Corporation.
