Head-mounted display

Abstract

A head-mounted display (HMD) 1, which is operated by a gesture operation performed by a user 3, is provided with a distance image acquisition unit 106 that detects a gesture operation, a position information acquisition unit 103 that acquires position information of the HMD 1, and a communication unit 2 that performs communication with another HMD 1′. A control unit 205 sets and displays an operating space 600 where a gesture operation performed by the user 3 is valid, exchanges position information and operating space information of the host HMD 1 and the other HMD 1 therebetween by the communication unit 2, and adjusts the operating space of the host HMD so that the operating space 600 and an operating space 600′ of the other HMD 1 do not overlap each other.

1 . A display apparatus comprising:
 a projector configured to project an image;   a display configured to superimpose the image projected from the projector on a nearby space and display the image as a mixed reality object;   a receiver configured to receive position information of the display apparatus;   a communication interface configured to communicate with another apparatus; and   controlling circuitry;   wherein the controlling circuitry is configured to set a first operating space in which a gesture operation of a user of the display apparatus may be performed and control the display so as to display the first operating space as the mixed reality object,   wherein the communication interface is configured to acquire information of a position and an operating space of the another apparatus,   wherein, if the controlling circuitry determines that the first operating space overlaps with the operating space of the another apparatus based on the position information received by the receiver and the information of the position and the operating space of the another apparatus acquired by the communication interface, the controlling circuitry is configured to calculate a second operating space which does not overlap the operating space of the another apparatus and control the display so as to display the second operating space;   wherein, if the controlling circuitry determines that the first operating space does not overlap with the operating space of the another apparatus based on the position information received by the receiver and the information of the position and the operating space of the another apparatus acquired by the communication interface after the second operating space is displayed, the controlling circuitry is configured to return the first operating space from the second operating space and control the display so as to display the first operating space.   
     
     
         2 . The display apparatus according to  claim 1 , wherein the second operating space is calculated by any of position movement, size reduction, and shape change of the first operating space, or in combination of the position movement, the size reduction, and the shape change. 
     
     
         3 . The display apparatus according to  claim 1 ,
 wherein the display is configured to display an operation object in order for a user to perform an operation of selection, display initiation, or display termination of a display image as a mixed reality object, and
 wherein, if the second operating space is displayed, the controlling circuitry is configured to control the display to move a position or reduce a size of the operation object so that the operation object enters within the second operating space. 
   
     
     
         4 . The display apparatus according to  claim 1 , wherein the display apparatus is a head-mounted display. 
     
     
         5 . A display apparatus comprising:
 an image projection unit that projects an image;   a display unit that superimposes the image projected from the image projection unit on a nearby space and displays the image as a mixed reality object;   a position information acquisition unit that acquires position information of the display apparatus;   a communication unit that communicates with another apparatus; and   a control unit;   wherein the control unit sets a first operating space in which a gesture operation of a user of the display apparatus may be performed and controls the display unit so as to display the first operating space as the mixed reality object,   wherein the communication unit acquires information of a position and an operating space of the another apparatus,   wherein, if the control unit determines that the first operating space overlaps with the operating space of the another apparatus based on the position information acquired by the position information acquisition unit and the information of the position and the operating space of the another apparatus acquired by the communication unit, the control unit calculates a second operating space which does not overlap the operating space of the another apparatus and controls the display unit so as to display the second operating space;   wherein, if the control unit determines that the first operating space does not overlap with the operating space of the another apparatus based on the position information acquired by position information acquisition unit and the information of the position and the operating space of the another apparatus acquired by the communication unit after the second operating space is displayed, the control unit returns the first operating space from the second operating space and controls the display unit so as to display the first operating space.   
     
     
         6 . The display apparatus according to  claim 5 , wherein the second operating space is calculated by any of position movement, size reduction, and shape change of the first operating space, or in combination of the position movement, the size reduction, and the shape change. 
     
     
         7 . The display apparatus according to  claim 5 ,
 wherein the display unit is configured to display an operation object in order for a user to perform an operation of selection, display initiation, or display termination of a display image as a mixed reality object, and
 wherein, if the second operating space is displayed, the control unit is configured to control the display unit to move a position or reduce a size of the operation object so that the operation object enters within the second operating space. 
   
     
     
         8 . The display apparatus according to  claim 5 , wherein the display apparatus is a head-mounted display.
