    摘要: The instant invention utilizes two, optionally orthogonal and optionally slightly tilted, horizontal magnetic sensors and, optionally, a 2 or 3 axis accelerometer or inclinometer to calculate a pitch, roll and tilt compensated heading. A vertical, Z, component is relatively constant compared to X and Y components, the Z component can be abstracted from the X and Y sensor when pitch and roll is applied based on Z offset measured with X or Y sensor at high tilt angles. Additional sensors tilted at various θ degrees can be added with a different angle α to X sensors when additional horizontal and magnetic coverage is desirable.

    摘要: A magnetic compass apparatus and method to account for magnetic distortion while determining a magnetic heading is disclosed. The method enables a compass module, comprising at least two magnetometers, to characterize its magnetic environment dynamically, while collecting data of a geomagnetic field; a user moves an apparatus through various orientations; the environment may or may not contain magnetic distortion influences. Data gathered by magnetometers and, optionally, accelerometers are processed through at least two filters before being transferred as a processed data set for repetitive measurement calculations. A series of calculations is executed recursively in time by solving one or more linear vector equations using processed data.

    摘要: The instant invention discloses a method for an orientation measuring instrument to isolate and separate gravitational and non-gravitational components of acceleration from accelerometer measurements by using an ambient magnetic field, typically the earth's magnetic field, as a fixed rotation reference. Using magnetic field measurements, one can track changes in orientation of a device and use that information to determine the gravitation direction, during periods when acceleration measurements include non-gravitational acceleration combined with gravitational acceleration components. In addition to determining orientation, a method and associated instrument provide a non-gravity acceleration vector of the device.

    摘要: A method and system for an interactive controller device comprising a two axis sensor in combination with one or more other sensors for hand-held devices operated in mid-air. A time sequence of measurements in three linearly independent directions is used to extract the angles of rotation around one or more distinct axes. A method is disclosed to approximately determine a transformation matrix, T, of a device orientation from a sequence of single vector measurements as a combination of rotations about specified axes. Calculated rotation angles can then be used to calculate changes in a controller or pointer position and a rate change thereof.
