A head-mount display apparatus includes a display element, a sight line direction detecting unit, an imaging unit, a sight line direction determining section that determines whether or not the line of sight is oriented downward based on a detection result from the sight line direction detecting unit, an operation determining section that determines whether or not the shape of a hand of the viewer shows a predetermined operation pattern based on a signal inputted from the imaging unit, and a display control section that controls display operation of the display element based on determination results from the sight line direction determining section and the operation determining section, and the display control section instructs the display element to display an operation object when it is determined that the line of sight is oriented downward and that the shape of the hand shows the predetermined operation pattern.
