The glass part 20 is formed to protect the eyes of the user. The shape of the glass part 20 is not particularly limited, and may include a screen (not shown) that can transmit various information to the user.

The prism unit 30 transmits the virtual environment displayed on the display 31 to the camera unit 40 or transmits the virtual environment to the user.

More specifically, the prism unit 30 includes a display 31 for displaying a virtual environment to a user, a projector 32 for transmitting a virtual environment to the camera unit 40, and a display unit 31 for receiving a virtual environment from the display 31, And a reflector 33 that transmits the light to the other user and reflects the light to some other users.

The display 31 is an element for displaying an image, and various display devices such as an LCD panel can be used, and a virtual environment can be displayed by being wired or wirelessly connected to the outside.

For example, the display 31 may be a reflection type silicon liquid crystal display (LCD), a digital light source (DLP), a micro LCD device coupled with a light source, or a micro OLED May be used, and the size is preferably 1 inch or less.

Since the microlens type silicon liquid crystal display device, the digital light source display device, and the micro LCD device are not self-luminescent, a light source must be coupled from the outside. Therefore, a transmission type micro LCD panel using a backlight or a reflection type micro light source using a front light LCD panel is possible. Since the micro OLED panel can self-emit light, a separate light source is not needed, so that the head-mounted display device can be made smaller.

The display 31 transmits the displayed virtual environment to the reflector 33 in the form of incident light.

The projector 32 can transmit the incident light incident from the reflector 33 as it is to the camera unit 40.

The reflector 33 may be formed as a reflective or transmissive surface that is reflected or transmitted depending on the polarized light component. For example, the P wave among the incident light emitted from the display 31 passes through the reflector 33 and enters the projector 32, and the S wave can be reflected by the reflector 33 and incident on the user.

Here, the display 31 and the projector 32 are formed in parallel, and the reflector 33 may be formed to be connected diagonally between the display 31 and the projector 32. Preferably, the reflector 33 may be formed at an angle of 45 degrees with the display 31 and the projector 32, respectively.

Here, the surfaces of the prism unit 30 other than the display 31, the projector 32, and the reflector 33 may be all in the form of a lens, and the surfaces of the display 31, And may be designed to change the optical path to the projector 32 or to the user. With such an optical path, the camera 41 can effectively receive the incident light incident on the display 31.

Therefore, the virtual environment transmitted from the display 31 through the structure of the prism unit 30 can be efficiently supplied to the user U or the camera 41 as described above.

The camera unit 40 photographs the virtual environment displayed to the user or photographs the outside environment in front of the user. That is, the camera unit 40 photographs a virtual environment or photographs an external environment in front of the user, the photographing angle being changeable.

Specifically, when the user and the user other than the user share the virtual environment, the camera section 40 switches the direction to the prism section 30 to photograph the virtual environment. When the user photographs the front environment, It is possible to photograph the external environment in front of the user. At this time, the camera unit 40 can switch the direction through the operation of the conversion lever 411. [
