System for cosmetic and therapeutic training

A method and system for compensating for significant soft iron magnetic disturbances in a heading reference system, such as an aircraft heading reference system, such as an integrated standby unit; or a vehicle inertial system, provides a heading correction signal to the heading reference system when a detected difference in value between a gyro heading relative to magnetic north and a magnetometer reading during a defined measurement period exceeds a predetermined acceptable threshold value of change, such as one based on the expected gyro drift over that period. Upon receipt of the heading correction signal, the gyro heading is adjusted to maintain an accurate heading relative to true magnetic north. If this threshold value is not exceeded, then the magnetometer reading is used for the heading value. This method is iteratively repeated in order to continually maintain an accurate heading and may be employed for each heading measurement axis.

A controller configured to control a pointer in a virtual reality environment includes a multi-axis magnetic field sensor, a multi-axis accelerometer, a gyroscope, a touchpad, and a wireless communications circuit. The controller can also include a processor and a memory storing instructions that when executed by the processor, cause the processor to obtain geomagnetic field data from the multi-axis magnetic field sensor, obtain acceleration data describing a direction and a magnitude of force affecting the controller from the multi-axis accelerometer, and obtain angular velocity data describing a rotational position of the controller from the gyroscope. The processor can communicate movement data to a computing device configured to generate a rendering of the virtual reality environment, the movement data describing an orientation of the controller wherein the movement data is based on at least one of the geomagnetic field data, the acceleration data, or the angular velocity data.
