Classification: CPC G  H  A | IPC A  G  H

Claim 16:
17. An apparatus, comprising:
a head-mounted device that includes a magnetic tracking system transmitter, and when worn by a user, is configured to present an extended reality view to the user;
a control device comprising one or more electromyography electrodes that contact the skin of the user when worn by the user, the control device comprising:
an analog circuit including an anti-aliasing filter and an amplifier configured to receive electromyography sensor signals from the one or more electrodes;
a shielding layer configured to shield the analog circuit from electromagnetic radiation produced by the magnetic tracking system transmitter;
an analog-to-digital converter (ADC) configured to receive analog sensor signals from the analog circuit and provide digital sensor signals, wherein the anti-aliasing filter is located proximate the ADC such that an electrical connection between the anti-aliasing filter and the ADC is approximately 1.5 cm or less;
a processor configured to receive the digital sensor signals and provide control signals based on the digital sensor signals;
a magnetic tracking system receiver; and
a control device antenna configured to transmit the control signals to the head-mounted device,
wherein the head-mounted device is configured to modify the extended reality view in response to the control signals.
