1. A head-mounted device comprising:
a mounted member mounted on a head of a user;
a detection device that detects a posture of the mounted member;
an output device that outputs at least one of an image or sound; and
a control device that switches a control mode of the output device and that receives an input signal related to the switching of the control mode, wherein
the control device determines whether the input signal is valid according to the posture of the mounted member detected by the detection device,
the output device includes a first display device and a second display device,
the detection device detects the posture of the mounted member with a rotation axis that is an axis along a direction in which the first display device and the second display device are aligned, and
the control device determines whether the input signal is valid according to a rotation angle formed by a virtual plane orthogonal to a vertical direction and the direction in which the first display device and the second display device are aligned, and a direction orthogonal to the direction in which the first display device and the second display device are aligned in the mounted member.
