A transmission type head-mounted display device includes a sound acquiring unit configured to acquire sound on the outside, a sound identifying unit configured to identify specific sound in the acquired sound, an image display unit capable of displaying an image and capable of transmitting an outside scene, an image storing unit configured to store an execution function image representing a function executable by the head-mounted display device and a specific sound image associated with the specific sound, a display-image setting unit configured to cause the image display unit to display a combined image obtained by combining the execution function image and the specific sound image, and a function executing unit configured to execute a function corresponding to the execution function image combined with the specific sound image associated with the acquired specific sound.

Head-mounted display device, control method for head-mounted display device, and computer program

The semiconductor of the present invention comprises: a buffer circuit ( ) which operates by the supply of a first power source potential VDD and an N-type MOSFET ( ) connected between a pad ( ) pulled up to a second power source potential VDD and a ground. An output line ( ) of the buffer circuit ( ) is connected to a gate of the N-type MOSFET ( ). The semiconductor further comprises a potential setting circuit ( ) which sets a potential of the output line ( ) of the buffer circuit ( ) to a level lower than the threshold level of the N-type MOSFET ( ) when the supply of the first power source potential VDD is shut off. This potential setting circuit ( ) has a first and a second N-type MOSTETs ( ) which are connected in parallel between the output line ( ) of the buffer circuit ( ) and the ground. The first N-type MOSTET ( ) has a gate connected to the output line ( ) and functions as a forward diode. The second N-type MOSFET ( ) has a gate connected to the pad ( ) and is made conductive by a rise in the potential of the pad ( ) to make the potential of the output line ( ) to be the ground potential.
