Abstract: 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.

If the key unit KU(k,x) connected with the k-th column signal line C(k) and the x-th row signal line R(x) is depressed, a scan voltage is transmitted from the k-th column signal line C(k) to the x-th row signal line R(x) through a switch sw(k,x) of the key unit KU(k,x). The transition circuit TC(x) connected with the x-th row signal line R(x) is turned on according to the scan voltage. Consequently, an output voltage Rout(x) from the transition circuit TC(x) has a first voltage level.
