Description

[0001] The present invention relates to an HMD device,

The present invention relates to an HMD device in which a terminal is fixed, and more particularly, to an HMD device in which a terminal or a terminal equipped with a case is fixed in an internal space of the HMD device regardless of its size.

Generally, a virtual reality (hereinafter referred to as "VR") is a virtual world in which time or space is far away, or a virtual reality which is not real at all is generated by a computer in a similar manner, And it is possible to manipulate it according to the movement of the body.

These attempts have existed since the beginning of the flight simulator or the remote operation of the robot, and recently it has been applied to the game world as well.

In order to experience such a virtual reality, a variety of electronic devices in a form that can be worn directly on the body are being developed. These devices are commonly referred to as wearable electronic devices.

Examples of wearable electronic devices worn on any part of the body include a head-mounted device (HMD) mounted on a user's head or head to display an image, a smart glass, a smart clock or a band the HMD may have various forms, such as a smart watch, a wristband, a contact lens type device, a ring type device, a shoe type device, a clothes type device, a glove type device, Shape or an eyeglass shape, and the wearable electronic device can be directly worn on the body, so that portability and user's accessibility can be improved.

Conventional wearable electronic devices, however, have a disadvantage in that a wearable electronic device having a unique wearable electronic device is provided according to the type of the terminal, or the portable terminal is detached from the terminal, .

In order to solve such a problem, a smartphone coupling adapter is provided inside the HMD device such that it can be installed regardless of the size and type of the smartphone, such as Korean Registered Patent No. 10-1530788 (registered on May 22, 2015) It is described that, when the adapter is mounted on the HMD main body, it corresponds to a plurality of 3D images of the HMD main body, and the adapter is configured to be able to attach and detach a corresponding type of smartphone. However, There is an inconvenience that an adapter for connecting a smartphone is separately needed when the type of the smartphone is changed while using the HMD device.
