Sensor Fusion on Android Devices: A Revolution in Motion Processing
Google TechTalks
David Sachs of InvenSense explains how gyroscopes, accelerometers and compasses work on their own and together, demonstrated on a modified Android handset. He covers sensor fusion algorithms and why rotation math such as Euler angles matters.
HN recommends it as the definitive talk on mobile motion sensing, including why integrating acceleration twice drifts so badly.
