Description

  The present invention relates to a head mounted display.

  In recent years, various head-mounted image display devices for observing an image displayed on a display such as a liquid crystal panel (LCD) as a virtual image enlarged through an optical system having an eyepiece, a half mirror, and the like have been proposed. It is called a head mounted display. An example of such a head mounted display is described in, for example, WO 2004/061519 A1 (Patent Document 1).

  In many cases, the video display device is configured to be worn on the face in a form wound around the head, and corresponds to one eye of the binocular type in which a video display system is formed at a position corresponding to both eyes and one of the left and right eyes. There is a one-eye type in which an image display system is formed at a position. Such a head-mounted display usually has a display unit for displaying video and a headphone for outputting sound.

Such operation components (switches, etc.) for operating the head mounted display may be provided in a control box or the like separate from the main body mounted on the head. In that case, a cable connecting the control box and the main body, etc. Is necessary, and there is a problem that it interferes with the operation. Therefore, attempts have been made to attach these operation components to the headphone portion of the head mounted display main body portion mounted on the head.
WO2004 / 061519A1 publication

  In a single-eye head-mounted display, two support headphone parts connected by a connection part, and a support arm attached to one of the headphone parts so as to be rotatable about the left-right direction when mounted. And a display unit that is attached to the tip of the support arm and displays an image on one eye of the user, rotates the support arm about 180 °, and By replacing, the thing which has the function which interchanges the right and left of the eye which displays an image | video is becoming mainstream.

  In such a head-mounted display, for example, when an operation component is attached to the headphone unit, when the head-mount display is used for the left eye and for the right eye, before and after the attachment position of the operation component Will be replaced. There is a problem that it is difficult for the user to operate.

  Also, trackballs, dials, cross keys and the like are generally operated with the thumb, but in the case described above, there is a problem that it is difficult to operate with the thumb.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a head-mounted display that does not change the position of the operation component even when the left and right sides are interchanged and is easy to operate with the thumb.

  The subject includes two headphone parts connected by a connecting part, a support arm attached to one of the headphone parts so as to be rotatable about a left-right direction when mounted, and the support arm. A display unit that displays an image on one eye of the user, rotates the support arm about 180 °, and swaps the left and right of the mounting of the headphones. A head-mounted display having a function of switching the left and right eyes of the display, and an operation component for controlling the head-mounted display or a device connected thereto is provided at a rear end portion of the support arm. This is solved by the featured head mounted display.

  According to the present invention, it is possible to provide a head-mounted display that is easy to operate with the thumb without changing the position of the operation component even when the left and right are switched.

  Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing an outline of a head mounted display as an example of an embodiment of the present invention. In the head mounted display 1, the headphones 2 and 3 are connected by the connecting part 4, and the connecting part 4 has elasticity. At the time of wearing, the earphones 2 and 3 are put on both ears and pressed by the elasticity of the connecting portion 4. A support arm 5 is attached to the headphone 3 so as to be rotatable about the left and right direction when mounted, and a display unit 6 for displaying an image on the user's eyes is provided at the tip. It is attached. The support arm 5 is slidable back and forth.

  When this head mounted display is used for the right eye, the support arm 5 is rotated by 180 ° about the rotation shaft 7 from the position shown in FIG. Can be used as

  FIG. 2 is a view showing a rear end portion of the support arm 5. A cross key 8 as an operation part is attached to the rear end portion of the support arm 5 and can be operated with the thumb of the hand as shown in the figure. Even if the left and right sides of the head mounted display are exchanged, the position where the cross key 8 is attached does not change, so that the user can operate the cross key 8 without being confused. However, since the up / down / left / right direction of the cross key 8 is reversed by left / right switching, it is necessary to switch the function assigned to the up / down / left / right key of the cross key 8.

  As described above, there are a track ball and a dial as an operation part that is preferably attached to the rear end portion of the support arm 5. These are particularly suitable for operation with the thumb and are easy to attach to the rear end of the support arm 5. Of course, even a normal push button switch or the like can be attached to the rear end portion of the support arm 5.

It is a figure which shows the outline | summary of the head mounted display which is an example of embodiment of this invention. It is a figure which shows the rear-end part of the support arm of the head mounted display shown in FIG.
