Underwater AR display device for disaster safety education {Underwater AR display device for marine safety education}

The present invention relates to an underwater AR display device for disaster safety education, and more specifically, augmented reality (or mixed reality) for disaster safety education by grafting an AR display using an optical system to use it as an underwater AR display device for disaster safety education While it is configured to be easy to use as a device, it not only solves the problem of lowering recognition rate due to deepening distortion due to various image input information that can occur underwater, but also augmented reality for disaster safety education in real-time form. It relates to an underwater AR display device for disaster safety education that can be used repeatedly as a device that allows a user to perform or easily receive disaster safety education even in the water by allowing the input and output of content to proceed smoothly.

As is well known, most of the communicable underwater masks that have been proposed until recently are limited to a transmission/reception structure connected with a wired cable. That is, a microphone for amplifying the wearer's voice is installed in the vicinity of the breathing tube insertion port inside the currently marketed underwater mask, and on one side thereof, a wired transceiver unit and an earphone for receiving the voice transmitted from the ground are provided. In addition, it can be seen that the transceiver unit has a structure connected to the ground transceiver unit by a wired cable.

However, in the case of the conventional underwater mask, since the transmission/reception device by the wired cable is mainly mounted, the wearer's movement is slowed and the use is limited, and when the wired cable is wrapped around the wearer's body, there is a risk of a safety accident In addition, the cable life was short due to the rapid aging of the wired cable due to salt, and the cable could be cut or damaged depending on the external harsh environment including communication obstacles such as topographical features, and communication was interrupted due to this There was a problem that often occurred.

In addition, the conventional general underwater mask has a complicated and heavy structure because it is necessary to untie the wired cable for communication to a sufficient length or to provide a separate winding device for winding it to an appropriate length when diving. Because most of them were made for use, it was difficult to operate and handle without ordinary skilled workers, and the equipment was expensive, so it was not suitable for general leisure use. Under these circumstances, it was necessary to develop an underwater mask with better performance and high universality, but a clear development product has not yet appeared.

For example, according to Korean Patent Application Laid-Open No. 10-2003-0073015, 'In an underwater mask provided with a sight window, an exhaust valve pipe part capable of outward exhaustion, and a breathing tube insertion port for attaching a breathing tube to the mask body, the mask body a storage tubular body protruding so that a predetermined sealed space portion can be provided on both sides; a transceiver unit for wireless communication that is hermetically accommodated in either the housing; a power supply unit that is hermetically accommodated in the housing on the other side and is electrically connected to the transceiver unit to supply power so that the transceiver unit can be operated; an antenna drawn upward from the transceiver unit to wirelessly transmit a voice signal of a mask wearer or wirelessly receive a voice signal transmitted from the ground; a microphone electrically connected to the transceiver unit and installed inside the mask body adjacent to the breathing tube insertion unit to amplify and transmit the mask wearer's voice; and an earphone installed in a state drawn out inside the mask body to transmit a voice signal received through the antenna and the transceiver unit to the mask wearer. present.

However, in the case of the above-mentioned prior literature, wireless transmission and reception with the ground is possible, so there is no risk of safety accidents like a wired cable, and there is also an effect of doing it wirelessly. Or, it will be said that there is a limit to the absence of high-level performance and technical elements such as functions such as VR (augmented reality).
