Abstract

<P>PROBLEM TO BE SOLVED: To provide a head-mounted display which can be properly operated without seeing an operation component. <P>SOLUTION: The rear edge of a support arm 5 is composed of a flexible member 5a, and is bent by applying force thereto. A bending direction is detected by a strain sensor (not shown) that is buried in the flexible member 5a or is stuck to the flexible member 5a. Accordingly, the bending direction of the flexible member 5a is detected in four, or eight divisions, or the like. When bending in a prescribed division direction is detected, it is determined that an operation corresponding thereto is input, thereby serving as the operation component, such as a push button switch. <P>COPYRIGHT: (C)2008,JPO&INPIT

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 or the like connecting the control box and the main body 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 to be mounted on the head.
WO2004 / 061519A1 publication

  In a single-eye head-mounted display, two headphone units connected by a connecting unit, a support arm attached to one of the headphone units, and a tip of the support arm are attached to the user. Those having a display unit for displaying an image on one eye are becoming mainstream.

  In such a head-mounted display, for example, when an operation component is attached to the headphone unit, the attachment position of the operation component cannot be visually observed, and the operation is frustrated, so the operation may not be performed accurately. There is a problem that there is.

  This invention is made | formed in view of such a situation, and makes it a subject to provide the head mounted display which can perform exact operation even if it cannot visually observe an operation component.

  The problem is that two headphone parts connected by a connecting part, a support arm attached to one of the headphone parts, and a tip of the support arm are attached to the user's eye. A head-mounted display having a display unit for displaying, wherein a rear end portion of the support arm has flexibility, and a predetermined operation input is performed according to a bending direction of the rear end portion. It is solved by a head mounted display characterized by the above.

  According to the present invention, it is possible to provide a head-mounted display that can be accurately operated even when the operating component cannot be visually observed.

  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

  The rear end portion of the support arm 5 is composed of a flexible member 5a, and is bent by applying a force to this portion. The direction of bending is detected by a strain sensor (not shown) embedded in the flexible member 5a or attached to the flexible member 5a.

  Therefore, it is assumed that the bending direction of the flexible member 5a is detected by dividing into, for example, four divisions, eight divisions, etc., and when a bending in a predetermined division direction is detected, an operation input corresponding to that is made. Can be used in place of operation parts such as push button switches.

  When the rear end portion of the support arm 5 can be sufficiently searched by hand and a predetermined input can be performed by bending the flexible member 5a, a push button switch or the like attached to the headphone is operated. Compared to, operation is simple and can be performed reliably.

It is a figure which shows the outline | summary of the head mounted display which is an example of embodiment of this invention.
