Systems Having Peripherals With Magnetic Field Tracking - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18180700 Titled 'Systems Having Peripherals With Magnetic Field Tracking'
Simplified Explanation
The abstract describes a device, such as a head-mounted device, that emits a magnetic field. This device is connected to a wireless controller that has sensors to monitor the magnetic field, as well as the orientation of the controller relative to gravity and the Earth's magnetic field. The controller uses this data to determine its position and orientation, which can then be wirelessly transmitted to the head-mounted device to control it.
Original Abstract Submitted
A head-mounted device or other electronic device may emit an alternating-current magnetic field. A wireless controller may have alternating-current magnetometers for monitoring the alternating-current field. The wireless controller may also have an accelerometer for measuring the orientation of the controller relative to the Earth's gravity and a direct-current magnetometer for measuring the orientation of the controller relative to the Earth's magnetic field. The alternating-current magnetometers may be three-coil magnetometers located at different locations in a controller housing. Using data from the alternating-current magnetometers, the direct-current magnetometer, the accelerometer, and/or other sensors, the wireless controller can determine the position and orientation of the wireless controller. This information can be wirelessly transmitted to the head-mounted device to control the head-mounted device.
