Abstract:
1. A head mount display comprising: a display unit which is configured to transmit an ambient light therethrough, and configured to project an image light corresponding to image data onto an eye of a user in order to allow the user to observe an image corresponding to the image light; an imaging unit which is configured to image at least a portion of a field of view of the user; an image analyzing unit which is configured to analyze an image imaged by the imaging unit; a hand detection unit which is configured to detect a hand of the user based on a result of an analysis performed by the image analyzing unit; a position definition unit which is configured to define a display position to display a selected virtual operation panel which is selected by the user from a plurality of virtual operation panels such that the selected virtual operation panel moves on the screen coextensively with movement of the hand of the user which is observed by the user through the display unit; a display control unit which is configured to control the display unit such that the display unit displays the selected virtual operation panel at the display position; an operation detection unit which is configured to detect an operation conducted by a finger of the user; an operation determination unit which is configured to determine whether or not the selected virtual operation panel is operated based on the operation conducted by the finger detected by the operation detection unit; and an operation control unit which is configured to perform a control corresponding to an operation position on the selected virtual operation panel when the operation determination unit determines that the selected virtual operation panel is operated, wherein the position definition unit defines a first specified portion of the hand of the user as a reference position based on a position of the hand of the user detected by the hand detection unit, and the position definition unit defines the display position for the selected virtual operation panel and assumes a predetermined positional relationship between the reference position and the display position, arranges the display position in a display area displayed by the display unit and the position definition unit fixes a secondary display position of each non-selected virtual operation panel while not allowing each non-selected virtual operation panel to move on the screen coextensively with the movement of the position of the hand of the user.
