Claim 15:
16. A head-mounted display, comprising:
a housing including an eye chamber to be positioned adjacent to eyes of a user;
a headband configured to secure the housing to a head of the user;
a motion tracking system that is operable to measure relative motion between the housing and the eyes of the user;
hand presence sensors on sides of the housing; and
an adjustment mechanism operable to:
increase a tightness of the headband relative to the housing in response to an output signal from the motion tracking system, the output signal representing relative motion between the housing and the eyes of the user above a threshold value; and
loosen the headband relative to the housing in response to output signals from the hand presence sensors, the output signal representing that both hands of the user are detected by the hand presence sensors.
