1. An apparatus, comprising:
a head-mounted device that, when worn by a user, is configured to present an extended reality view to the user; and
a control device comprising one or more electrodes that, when worn on a wrist of the user, contact the skin of the user, the control device comprising:
an analog circuit including an amplifier configured to receive sensor signals from the one or more electrodes and an anti-aliasing filter;
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; 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.
