摘要： A system and a method for determining an attitude of a device undergoing dynamic acceleration is presented. A first attitude measurement is calculated based on a magnetic field measurement received from a magnetometer of the device and a first acceleration measurement received from a first accelerometer of the device. A second attitude measurement is calculated based on the magnetic field measurement received from the magnetometer of the device and a second acceleration measurement received from a second accelerometer of the device. A correction factor is calculated based at least in part on a difference of the first attitude measurement and the second attitude measurement. The correction factor is then applied to the first attitude measurement to produce a corrected attitude measurement for the device.

摘要： A system and a method for performing a rolling gesture using a multi-dimensional pointing device. An initiation of a gesture by a user of the multi-dimensional pointing device is detected. A rolling gesture metric corresponding to performance of a rolling gesture comprising rotation of the multi-dimensional pointing device about a longitudinal axis of the multi-dimensional pointing device is determined. Information corresponding the rolling gesture metric is conveyed to a client computer system, wherein the client computer system is configured to manipulate an object in a user interface of the client computer system in accordance with the rolling gesture metric.

摘要： A system, a computer readable storage medium including instructions, and a method for determining an attitude of a device undergoing dynamic acceleration. A difference between a first accelerometer measurement received from a first multi-dimensional accelerometer of the device and a second accelerometer measurement received from a second multi-dimensional accelerometer of the device is calculated. A Kalman gain is adjusted based on the difference, wherein the Kalman gain is used in a Kalman filter that determines the attitude of the device. An attitude of the device is determined using the Kalman filter based at least in part on the Kalman gain, the first accelerometer measurement, the second accelerometer measurement, and a magnetic field measurement received from a multi¬ dimensional magnetometer of the device.
