Description

Apparatus for experiencing the virtual reality}

The present invention relates to a virtual reality experience device, and in particular, to a virtual reality simulator for safety education on citizen safety, earthquakes, tsunamis, landslides, forest fires, building collapse, war, climate change, and construction sites. Each of the various experience environments for each module is composed of one module, and the modules are combined into one frame according to the needs of the safety training situation. In addition, the frames in which the modules are combined are arranged continuously or at a certain distance apart to create a virtual reality environment. This relates to a virtual reality experience device that allows the experiencer to visually and physically experience virtual reality continuously, sequentially, quickly, and more realistically.

Various types of safety accidents occur at sites of various safety accidents, such as citizen safety, earthquakes, tsunamis, landslides, forest fires, building collapses, war, climate change, and construction sites. Looking at these types of accidents, there are accidents that occur due to simple mistakes even though they were predictable, and there are accidents that occur in completely unexpected places.

However, even though it is possible to predict accidents, most of the causes of accidents, which do not decrease every year, are caused by a lack of knowledge about the possibility and risk of accidents and a relaxed attitude of thinking that accidents are simply someone else's problem.

For example, when it comes to safety accidents that occur at construction sites, large companies provide their own training or prepare many warning signs at construction sites, and various educational institutions also run various programs to prevent accidents. However, it is difficult to expect effects beyond a certain level.

In other words, no matter how much training is provided, accidents cannot be reduced unless each worker working at a construction site directly feels the possibility and risk of accidents.

In addition, because there has been no education system that allows realistic experiential learning for workers working at construction sites until now, more effective safety education has not been provided. This fact has led to safety accidents large and small, resulting in many casualties and material damage. It acts as a factor causing .

Safety accidents that mainly occur at construction sites include falls caused by not wearing a seat belt, falls caused by openings, falls caused by tipping over railings, falls caused by defective temporary passageways, accidents caused by constriction by construction equipment, and failure to wear safety helmets/safety shoes. It is easy for various safety accidents to occur, such as fire accidents, collapse and fall accidents due to poor scaffolding installation, electric shock accidents, mobile workbench tipping accidents, and chemical spraying.

Therefore, if you want to provide safety education for such accidents, it is most desirable to set up an environment similar to an actual construction site and allow the experiencer to directly experience the safety accident. However, in this case, the cost of establishing an experience environment is high. There was a major problem.

Therefore, in order to solve this problem, recently, technologies have been proposed that enable virtual experience of safety accidents at construction sites through a virtual environment simulator. An example of this is Registered Patent No. 10-2192135. In (virtual experiential safety training system),

A carrier that has a storage space inside and includes a storage box that can be opened and closed by a cover, and a power module for supplying power and a Wi-Fi module that provides a local network are mounted in the storage space;

A tablet used as an operating computer; and

It is used as a plurality of experience simulators and has a plurality of viewers that display virtual reality including selectable objects on a screen,

The storage space is divided into a central row, first rows and second rows formed on the sides of the central row,

The power module and the Wi-Fi module are mounted in the central row,

A tablet pocket for storing the tablet and a plurality of viewer pockets for storing the viewer are formed in the first row and the second row,

For movement, the tablet and the plurality of viewers are stored in the tablet pocket and the plurality of viewer pockets of the carrier,

For a virtual experience, the tablet and the plurality of viewers are retrieved and communicate through the local network provided by the Wi-Fi module,

A content list for the experiencer's virtual experience for each of the plurality of viewers is set using an operation manager provided on the tablet,

We proposed a structure in which the virtual reality for virtual experience is displayed for each of the plurality of viewers by running the contents corresponding to the content list.

However, safety accidents at construction sites caused by these conventional technologies, as well as safety accidents caused by citizen safety, earthquakes, tsunamis, landslides, forest fires, building collapse, war, and climate change, are caused by the experiencer wearing a viewer, or HMD (Head Mounted Display). , It is a structure that allows indirect experience through images displayed on the viewer, but there is a problem in that a realistic experience cannot be achieved.

In other words, since visual experience is achieved only through content that is displayed simply through software, that is, images, it is necessary to protect citizens from accidents such as falls, constriction accidents, fire accidents, collapse accidents, electric shock accidents, falling accidents, chemical spray, traffic accidents, earthquakes, etc. , by experiencing various safety accidents caused by tsunamis, landslides, forest fires, building collapses, wars, climate change, etc. only through software, a realistic experience is not possible, which greatly reduces the effectiveness of safety accident experience training. there is.

In accordance with the purpose of the virtual experience, a device for the virtual experience is implemented by selectively assembling modules on the ceiling, walls, and floor of a single frame, and the experiencer wears the VR device and enters the inside of the device to experience various virtual experiences. The purpose is to provide a virtual reality experience device that allows people to directly experience real-life safety accidents.

The virtual reality experience device according to the present invention to achieve the above purpose,

A frame for implementing a polyhedron;

A modular driving unit that is selectively attachable and detachable to each side of the frame and physically implements a safety accident experience situation;

HMD worn by the experiencer;

It is characterized by consisting of a control unit that controls the operation of the driving unit to match the virtual reality image displayed on the HMD.

In addition, the inside of the frame is provided with a spray driver for spraying or irradiating air, steam, laser beam, or light, and the control unit controls the spray driver to match the image displayed on the HMD.

In addition, a camera is further provided inside the frame, and the control unit recognizes the image captured by the camera, confirms the location of the experiencer, and then controls the direction of the injection drive unit to be directed to the experiencer.

In addition, the driving unit is provided with a movable wall that moves inside the frame under the control of the control unit, and the movable wall is provided with a distance sensor and a pressure sensor,

The distance sensor detects the distance from the experiencer, and the pressure sensor detects the pressure on the experiencer's body,

The control unit moves the speed of the moving wall to the minimum speed when the distance between the experiencer and the moving wall approaches the set value according to the distance information detected by the distance sensor, and receives the value detected from the pressure sensor to control the moving wall. When it is determined that the experiencer has been contacted, the moving wall is further moved a set distance at the lowest speed while checking the pressing force, and when the pressing force exceeds the set value, the driving unit is controlled to move the moving wall backwards.

The virtual reality experience device according to the present invention configured in this way can selectively install each module on the frame to experience safety education such as citizen safety, earthquakes, tsunamis, landslides, forest fires, building collapse, war, climate change, and construction sites. It has the advantage of enabling more realistic safety education by enabling not only a visual experience through the HMD worn by the user, but also a physical experience through the module.

In addition, when virtual reality experience devices with a combination of modules are placed sequentially or spaced apart according to educational purposes, it is not only advantageous in terms of space, but also very advantageous as it allows experiencers to experience a variety of realistic safety education in one place in a continuous and sequential manner. It has the advantage of enabling safety education to be carried out economically.

The above-mentioned objects, features, and advantages will be described in detail later with reference to the attached drawings, so that those skilled in the art will be able to easily implement the technical idea of the present invention.

In describing the present invention, if it is determined that a detailed description of known techniques related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description will be omitted.

The terms used in the present invention are general terms that are currently widely used as much as possible while considering the function in the present invention, but this may vary depending on the intention or precedent of a person working in the art, the emergence of new technology, etc.

In addition, in certain cases, there are terms arbitrarily selected by the applicant, and in this case, the meaning will be described in detail in the description of the relevant invention.

Therefore, the terms used in the present invention should be defined based on the meaning of the term and the overall content of the present invention, rather than simply the name of the term.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

However, the embodiments of the present invention illustrated below may be modified into various other forms, and the scope of the present invention is not limited to the embodiments detailed below.

Examples of the present invention are provided to more completely explain the present invention to those skilled in the art.

In addition, with the present invention, it is possible to experience safety education on citizen safety, earthquakes, tsunamis, landslides, forest fires, building collapse, war, climate change, construction sites, etc. Hereinafter, for convenience of explanation, safety education at construction sites is provided. Although a virtual reality experience device is described as an example, the present invention is not limited to this and can be applied to all virtual reality simulators for experiencing various safety accidents.

As shown in Figure 1, the virtual reality experience device of the present invention is largely composed of a frame 100, a floor driving part 110, a wall driving part 120, 130, and 140, and an upper driving part 170.

The frame 100 has a shape that can be implemented as a hexahedron and has an open four-way side wall area, floor area, and ceiling area, and the open floor area is modularized so that a person can experience a fall or fall accident. The bottom driving part 110 is fastened.

In the present invention, the form of the frame 100 that can be implemented as a hexahedron is explained as an example, but it will be natural that it can be applied to any frame that can be implemented as a polyhedron.

As shown in Figure 3, the floor driving unit 110 is configured so that the floor surface can be tilted by the rotational drive of the eccentric motor, so that the experiencer can experience a falling or falling accident due to the tilted floor. , At construction sites, workers may fall due to poor installation of scaffolds, temporary passages, etc., or failure to wear seat belts, so this can be experienced in a virtual environment.

Of course, the floor driving unit 110 is not limited to this function and may have various structures to implement various floor environments.

As an example, the floor driver 110 may have a hexahedral shape and its edge may be fixed to the edge of the bottom of the frame 100 by being detachably fastened with a bolt or the like.

The open front part of the frame 100 is provided with an overturning drive part 150 for experiencing the overturning of a handrail or ladder. This overturning drive part 150 is in the form of a handrail and is configured to tilt forward by a hinge, and is operated by a motor. Alternatively, it may be configured to enable tilting operation by a hydraulic cylinder.

Preferably, it can be connected to the floor driving unit 100 so that it can be turned over when the floor is tilted by an eccentric motor. That is, the handrail of the overturning drive unit 150 is integrally provided in a vertical position on the front part of the floor installed to be tiltable, so that the floor of the floor drive part 100 tilts forward without any separate power, and the handrail is also provided together with the handrail. It may be configured to tilt forward and conduction.

Modular wall driving units 120 and 130 are mounted on both sides of the frame 100 and are coupled to each other by bolts, etc. to enable attachment and detachment. These wall driving units 120 and 130 prevent shocks from vehicles or construction equipment, pinch accidents, or collapse. You can experience accidents, etc.

As shown in Figure 4, the inner part of any one of the plurality of wall driving parts 120 and 130 is configured to move in the inner direction of the frame 100 by the cylinder, thereby applying shock to the experiencer or causing shock on both sides opposing each other. The wall driving parts 120 and 130 simultaneously move in the inner direction of the frame 100, allowing a constriction accident to be experienced.

At this time, in order to prevent safety accidents from occurring due to excessive shock or constriction of the experiencer, a distance sensor (S1) and a pressure sensor (S2) are provided on the moving wall of the wall driving units (120, 130). This prevents excessive shock from being applied to the experiencer.

For example, when the movable wall moves by the cylinder, the distance sensor (S1) detects the distance to the experiencer, and the pressure sensor (S2) detects the pressure on the experiencer's body, and the control unit 200 detects the distance According to the distance information detected by the detection sensor (S1), when the distance between the experiencer and the moving wall approaches within a set value, for example, within 30 cm, the wall driving parts 120 and 130 are installed to gradually reduce the speed of the moving wall so that it moves at the minimum speed. Control.

In addition, the control unit 200 receives the detected value from the pressure sensor (S2) and confirms the state in which the experiencer is in contact with the moving wall. In the initial contact state, the moving wall is moved 5 to 10 cm further at the lowest speed to prevent impact. In addition to applying pressure, the pressing force is continuously checked.

That is, when the wall driving units (120, 130) pressurize the experiencer from both sides to experience a constriction accident, when the pressing force exceeds the set value to prevent safety accidents caused by excessive pressure, the control unit 200 controls the wall driving parts (120, 130). This causes the moving wall to immediately move backwards, thereby releasing the constriction state.

As a result, the experiencer can safely experience impacts, constriction accidents, etc.

In addition, these wall driving parts 120 and 130 are provided with entrances 121 and 131 at the same positions, respectively.

Another modular wall driving unit 140 is assembled and mounted on the rear part of the frame 100, which can also have a movable wall that moves by a cylinder and, alternatively, is provided with an electrode plate to experience electric shock accidents, etc. It could be.

As shown in Figure 5, the upper drive unit 170 is modularized to experience falling objects or equipment being pinched, and is assembled and mounted on the upper side of the frame 100 to be detachable. This upper driving part 170 also allows the moving wall, that is, the ceiling, to move in the up and down direction by a cylinder or a folding member, so that the experiencer can be pressed from above.

In the case of the movable wall of the upper driving part 170, it has a distance sensor and a pressure sensor, so it can operate in the same or similar manner as the wall driving parts 120 and 130 under the control of the control unit 200.

In addition, the front part of the frame 100 is preferably opened so that the status of the person entering the frame can be confirmed from the outside and immediate action can be taken in case of an emergency.

In addition, the frame 100 can be formed in the form of a polyhedron as well as a hexahedron, and a modular wall driving part can be assembled on each side to be detachably mounted, and each floor driving part 110 and a wall driving part ( 120, 130, 140), and the upper drive unit 170 can also appropriately arrange modules with various functions to physically realize virtual reality.

Additionally, a display panel 160 may be mounted on the upper side of the open front portion of the frame 100 to inform other experiencers observing the experience progress and various information from the outside.

On the other hand, the wall driving units 120 and 130 may be equipped with only a plurality of distance detection sensors (S1) excluding contact sensors as shown in Figure 6. These distance detection sensors (S1) may be composed of photo sensors, and the experience user A plurality of distance detection sensors (S1) are arranged laterally in the upper body area while maintaining a constant distance from neighboring distance detection sensors.

Therefore, when the moving wall moves by the cylinder, the distance detection sensor (S1) detects the distance from the experiencer, and the control unit 200 determines the distance between the experiencer and the moving wall based on the distance information detected by the distance detection sensor (S1). When the distance approaches within the set value, for example, within 30 cm, the speed of the moving wall is gradually reduced and the wall driving units (120, 130) are controlled to move at the minimum speed, and the moving wall and When the distance between the experiencers becomes '0' and contact occurs, the moving wall is moved 5 to 10 cm further at the lowest speed while in contact to apply impact.

In the end, it was possible to experience a shock accident safely by applying only minimal shock to the person experiencing it.

As shown in Figure 7, the upper driving unit 170 also has a plurality of distance detection sensors (S1) composed of photo sensors arranged in the form of n × m while maintaining a constant distance from neighboring distance detection sensors, and the control unit 200 ) will be able to control the driving of the ceiling, that is, the moving wall, in the same or similar manner as the wall driving units 120 and 130 by this distance detection sensor (S1).

Meanwhile, a spraying unit 180 is installed at the four inner corners of the frame 100 as shown in FIG. 8, and a camera is installed inside the frame 100. The spraying unit 180 It has a plurality of nozzles 181 in the vertical direction to experience fire, gas leak, chemical scattering, etc., and hot air, air, etc. are sprayed through these nozzles 181.

In particular, in order to accurately spray air or hot air to the experiencer, the injection drive unit 180 can swing in the left and rear direction as shown in Figure 9, and the control unit 200 recognizes the image captured by the camera 210 and After determining the position, the swing state of the injection drive unit 180 is controlled to face the direction of the experiencer, as shown in Figure 10, and the air or hot air is controlled to be sprayed.

Of course, this injection drive unit 180 may be provided with a structure for irradiating a laser beam, light through an LED, etc.

The virtual experience device of the present invention, in which the floor driving part 110, the wall driving part 120, 130, 140, the conduction driving part 150, and the upper driving part 170 are assembled to the frame 100, can be used in field situations, experience situations, etc., as shown in FIG. 11. By arranging a plurality of virtual experience devices in succession, it is possible to move directly to a neighboring virtual experience device through the entrance and have another experience.

Alternatively, it is natural that it can be positioned independently and away from neighboring virtual experience devices.

Therefore, as shown in Figure 12, when the experiencer wears the HMD and then enters the first virtual experience device through the entrance, the control unit 200 is linked with the software driving unit 300 that implements the virtual reality displayed on the HMD to control each driving unit. By controlling (110, 120, 130, 140, 150, 170, 180), it is possible to experience the virtual environment for safety education at construction sites not only visually but also physically.

Of course, the virtual reality experience device of the present invention can experience not only construction sites, but also virtual environments such as citizen safety, earthquakes, tsunamis, landslides, forest fires, building collapse, war, and climate change, and it has modular driving units ((110, 120, 130, 140, 150, 170, 180). ) can be replaced or appropriately placed to implement various virtual environments.

By enabling continuous experience by moving from one virtual reality experience device to the next virtual reality experience device through an entrance, a more diverse and continuous virtual experience is realized quickly and realistically.

As the specific parts of the present invention have been described in detail above, it is clear to those skilled in the art that these specific techniques are merely preferred embodiments and do not limit the scope of the present invention. something to do.
