A head-mounted display apparatus worn on the head of a user and a method for controlling the head-mounted display apparatus are disclosed. The head-mounted display apparatus includes an attitude detector that detects the attitude of the head-mounted display apparatus, a manipulation detector that detects a predetermined manipulation performed on the head-mounted display apparatus, a display, and a processor. The head-mounted display apparatus switches a display of first display information to second display information according to a change in the attitude detected by the attitude detector. However, if the manipulation detector detects the predetermined manipulation, the head-mounted display apparatus maintains the display of the first display information without switching to the second display information even if there is a change in the attitude detected by the attitude sensor.
