Head-mounted display

A head-mounted display comprising:

• a projector configured to project an image;
• a see-through lens configured to superimpose the image projected by the projector on a nearby space and display the image as a mixed reality object;
• a receiver configured to receive position information of the head-mounted display;
• a communication interface;
• and
• a controller,
• wherein the controller is configured to:
• set a first operating space in which a gesture operation of a user of the head-mounted display may be performed,
• control the projector to display an image of the first operating space and an image of an operation object as the mixed reality object via the see-through lens, the operation object is an object operated by the gesture operation of the user of the head-mounted display and is displayed in the first operating space,
• acquire information of a position and a second operating space of another apparatus by the communication interface, the second operating space is a space in which a gesture operation of a user of the another apparatus may be performed,
• determine whether the first operating space overlaps with the second operating space based on the position information of the head-mounted display received by the receiver and the information of the position and the second operating space of the another apparatus acquired by the communication interface,
• calculate a third operating space which is reduced in size from a size of the first operating space so as not to overlap the second operating space if the first operating space overlaps with the second operating space, and
• control the projector so that a part of the operating object is set to non-display if an image of the third operating space is displayed as the mixed reality object via the see-through lens.
