Head-mounted display device, control method therefor, and computer program

A control method for a transmission-type head-mounted display device including an image display configured to, in a state in which the head-mounted display device is mounted on a head of a user, transmit an outside scene to cause the user to visually recognize the outside scene and superimpose a virtual image on the outside scene to cause the user to visually recognize the virtual image, the control method comprising:

• acquiring state information including a position of an own aircraft, which is a mobile body set as an operation target object of the user;
• calculating a positional relation of the position of the own aircraft with respect to a visual field of the user;
• determining whether the own aircraft is absent or present in the outside scene corresponding to the visual field of the user, based on the positional relation;
• and
• when the own aircraft is present in the outside scene corresponding to the visual field of the user, creating a first support image including support information for operation of the own aircraft and causing the image display to display the first support image as the virtual image.

A non-transitory computer readable medium with instructions stored thereon for controlling a transmission-type head-mounted display device including an image display configured to, in a state in which the head-mounted display device is mounted on a head of a user, transmit an outside scene to cause the user to visually recognize the outside scene and superimpose a virtual image on the outside scene to cause the user to visually recognize the virtual image, that when executed by computer, perform the steps comprising:

• acquiring state information including a position of an own aircraft, which is a mobile body set as an operation target object of the user;
• calculating a positional relation of the position of the own aircraft with respect to a visual field of the user;
• determining whether the own aircraft is absent or present in the outside scene corresponding to the visual field of the user, based on the positional relation;
• and
• when the own aircraft is present in the outside scene corresponding to the visual field of the user, creating a first support image including support information for operation of the own aircraft and causing the image display to display the first support image as the virtual image.
