1. A retraction system for retracting a visualization device configured to present virtual imagery to a user, the retraction system comprising:
a retraction assembly comprising an actuator and a tether, wherein a first end of the tether is configured to couple to the visualization device and a second end of the tether is coupled to the actuator; and
control circuitry configured to:
determine an attachment status of the visualization device with respect to a support, wherein the support comprises an interface device configured to couple to a head of the user, based on sensor data received at the control circuitry from one or more sensors positioned on the visualization device, the interface device, or any combination thereof; and
provide control signals to the actuator to retrieve the tether in response to determining that the attachment status of the visualization device transitions from an attached configuration in which the visualization device is attached to the support to a detached configuration in which the visualization device is detached from the support.
