DETACHABLE WEARING AID DEVICE AND HEAD MOUNTED DISPLAY HAVING THE SAME

The present invention relates to a detachable wear assisting device and a head mounted display having the same.

The head mounted display (HMD) is the most important device in the virtual reality industry. The head mounted display is not a conventional flat screen screen such as a television, a computer monitor, or a smart phone, but a display that can be displayed directly in front of the user's eyes by wearing it on the head with a screen mounted inside the pitched device itself. Means a play device. The head-mounted display realistically realizes virtual reality through its unique media characteristics, and the head-mounted display hardware having such characteristics has been produced and is expanding the market to the content area. Because HMD must be sealed due to its properties, it must be completely adhered to the skin. This causes hygiene problems when used by a large number of unspecified people.

The head mounted display devices that lead the current virtual reality market can be classified into two types, an integrated head mounted display and a smartphone detachable head mounted display, depending on the function.

Representative devices of the integrated head mounted display include Oculus Rift, HTC's Vive, and Sony's Playstation VR. Based on personal computer (PC) and console devices, the integrated head-mounted display provides high-quality display with wide viewing angle, as well as various sensors such as acceleration sensor, gyro sensor, and proximity sensor. The disadvantage is that it is inconvenient to carry due to the computer and console, and the initial purchase cost is high, but it is evaluated as the most advanced head mounted display device among the virtual reality devices to date. In particular, the integrated head-mounted display has a large number of contents supported through its own content distribution system, Oculus Store or Steam, and has a wide range of applications for high-end games, video, leisure, and sports. There is this.

Unlike the integrated head-mounted display device, the smartphone detachable head mounted display is easy to combine with a smartphone that has a low price and high penetration rate, leading the popularization of virtual reality. Typical devices include Samsung Electronics' Gear VR, Google's Daydream View and Cardboard. Because it uses a display and system as a smartphone, it is easy to carry. You can enjoy a variety of content regardless of the space or place, so it has the advantage that it can be combined with various fields such as educational content as well as watching games and movies.

1 is a view showing a typical HMD form by way of example. Referring to FIG. 1, when an unspecified number of people use the same HMD, hygiene problems may be caused to the skin contact area. Accordingly, disposable masks are provided in amusement parks and VR rooms. The user wears a disposable mask and overlays the mask. The disposable mask not only incurs a separate cost, but also takes a lot of time when worn and the user feels a foreign body. In most cases, a separate assistant assists the wearing of the disposable mask, which leads to a higher fixed cost for content management.

In general, the head mounted display (HMD) is completely in close contact with the wearer's skin because of its nature. This can cause hygiene problems when used by a large number of unspecified people. Currently, disposable masks are provided to users to solve these hygiene problems. However, the disposable mask incurs a cost, and it is not easy to wear in the case of a user who has no experience in wearing, and due to the difficulty in wearing, an auxiliary manpower to help wear is required, leading to an increase in operating costs. In addition, since the disposable mask is not fixed, it is easy to slide and it is difficult to solve the original hygiene problem, and it may give a foreign feeling to the wearer.

The head mounted display according to an embodiment of the present invention may be implemented as a separation structure so as to be separated into a display unit having a display and a lens, and external light and a wear assisting device that contacts the user's skin. The detachable head mounted display can easily solve hygiene problems without using a disposable mask.

In addition, the head-mounted display according to an embodiment of the present invention can easily detach and recombine the connection portion of the display unit and the wearing assisting device by a method such as a magnet, a buckle or a clip, as well as a separation structure.

A head mounted display (HMD) according to an embodiment of the present invention is a sanitary problem even if an unspecified number of people use it in places such as an amusement park, a VR room, and a theater to experience content to which VR (Virtual Reality) technology is applied. Can be solved.
