  • Reducing interference between Electromagnetic Tracking systems
    Patent number: 11454810
    Abstract: A method of reducing a chance of interference between operations of two electromagnetic systems (e.g., AR/VR systems) is provided. The method includes determining one or more first frequencies at which a first electromagnetic system is operating, identifying one or more second frequencies that do not interfere with the determined one or more first frequencies, and setting a second electromagnetic system to operate at the identified one or more second frequencies. Each of the first and the second electromagnetic systems includes a respective magnetic transmitter configured to generate magnetic fields, and a respective magnetic sensor configured to generate signals based on characteristics of the magnetic fields received at the magnetic sensor (e.g., from the respective magnetic transmitter).
