Abstract

A HMD photographs at least a portion of a field of view of a user, and detects a hand of the user based on a result of analysis of an imaged image. The HMD performs a control of deciding and displaying a position of an operation part of a virtual operation panel based on a position of the detected hand of the user. A position associated with the hand visible to the user is set as a display position of the virtual operation panel which tracks the position of the hand of the user. The HMD determines whether or not the virtual operation panel is operated based on a contact position of a finger of the user detected by a touch panel, and performs a control corresponding to an operation position of the virtual operation panel when it is determined that the virtual operation panel is operated.

A head mount display comprising:

a display unit which is configured to transmit an ambient light therethrough, and is 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 touch panel which is configured to detect a contact of the hand of the user therewith;
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 determination unit which is configured to determine whether or not the selected virtual operation panel is operated based on a touch position of a finger of the user detected by the touch panel;
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, and
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 which always assumes a predetermined positional relationship with the reference position and the display position in a display area displayed by the display unit, and the position definition unit fixes another display position of each of other virtual operation panels which are not selected by the user from the plurality of virtual operation panels without allowing the other virtual operation panels to move on the screen coextensively with movement of the position of the hand of the user.
