Abstract: Systems and methods for switching between data connections establishing between an augmented reality display unit and a peripheral device. The systems and methods can automatically switch between communication modules, antennas, or frequencies based on sensor data to reduce or eliminate the effects of proximity to or submersion beneath water. In some examples, switching between communication modules, antennas, or frequencies is based on motion of the user's head or the electrical resistance, salinity, or chemical composition of a body of water the augmented reality display unit is placed within.
