1. A head-mounted device, comprising:
a device housing;
a support structure connected to the device housing to support the device housing with respect to a user;
a display device connected to the device housing to display content;
a proximity sensor coupled to the device housing and configured to generate a proximity signal based on a distance between the device housing and the user;
a tension controller configured to:
track a nominal proximity value based on the proximity signal,
predict a future deviation from the nominal proximity value based on the proximity signal,
determine a tension level based on the prediction, and
determine a tensioning command based on the proximity signal and the tension level; and
a tension adjuster that applies tension to the user according to the tensioning command to restrain motion of the device housing with respect to the user.
