Meanwhile, the game progress unit 100 may provide disaster events and mission information generated by the mission generation unit 200 described later in the course of the game progress. Specifically, when a disaster event related to an earthquake occurs, the game progress unit 100 may provide a vibration effect to a specific 3D object to provide an effect that the user's view is shaken. As another example, when a disaster event occurs, the game proceeding unit 100 causes the announcement to notify the speaker object to be output, and when an earthquake occurs during the game, the mission information to be evacuated under the desk within the reference time is voice or text. Can be provided as

In addition to this, as will be described later, the game proceeding unit 100 may change the movement speed of the user according to the weight of the items (3D virtual objects) collected by the user, thereby reducing the movement speed as more objects are collected, thereby providing a sense of reality. .

The mission generator 200 may apply a disaster event for a specific disaster situation to a virtual space and generate mission information for the disaster event.

First, the mission generator 200 may generate and store a plurality of disaster events for each disaster situation in advance, such as fire, earthquake, flood, power failure, and the like. The mission generator 200 may simulate any one disaster event selected by the user or randomly selected in the virtual space.

As another example, the mission generating unit 200 may apply a shaking effect to a building when an earthquake event occurs, and simulate a falling object, a crack in an outer wall, a shaking effect, and the like. The mission generation unit 200 may improve the immersion of the user by generating such a disaster event at any time during the game.

At the same time, the mission generating unit 200 may generate mission information for overcoming the selected disaster event. For example, the mission generating unit 200 has a 'earthquake occurred. Escape outside the building '. Or, the mission generating unit 200

Meanwhile, the mission generator 200 may generate sub-mission information related to a disaster event. For example, the mission generating unit 200 may generate sub-mission information associated with previously generated mission information, such as 'a strong earthquake has been detected, so evacuate under the desk' during a mission escaping outside the building.

The behavior analysis unit 300 may analyze a user's behavior for a disaster event in a mission performance process based on log data generated in the process of performing mission information.

Specifically, the behavior analysis unit 300 analyzes log data generated based on a user's manipulation signal received through a controller interworking with the virtual reality-based disaster evacuation education device 1, and the user collects it during the game execution process Analyze the type of item as a 3D virtual object.

You can analyze the types of dimensional virtual objects. In this regard, it will be described with reference to FIG. 2 together.

2 is a diagram illustrating an example of a game screen that interacts with a specific 3D virtual object.

The behavior analysis unit 300 may detect whether there is an interaction between users and an object (a 3D virtual object) by using a focus function supported by a VR device, such as a Google Cardboard SDK.

For example, when the user moves the gaze, the focus displayed on the center of the screen also moves within the 3D virtual space. Through this, when focusing on a specific object, the game progress unit 100 displays the corresponding 3D virtual object (shown) In an embodiment, the effect of highlighting on the edge of the keyboard) may be provided. That is, when the focus is located on a specific 3D virtual object, a highlight effect may be set on the outline of the 3D virtual object.

In addition, the behavior analysis unit 300 analyzes the generated log data to identify where the user is located in the virtual space in the course of mission execution by time.

That is, the behavior analysis unit 300 may analyze log data related to movement and analyze whether a user is located in a preset evacuation site or a dangerous place for each disaster event in a mission performance process based on location data in a virtual space. For example, when mission information to move to a specific place is generated within 10 seconds, it may be determined whether the location of the user has arrived at a specific place after 10 seconds.

The score calculator 400 may calculate a corresponding score for mission information performance based on the analysis result of the behavior analyzer 300.

Here, the response score is information used as a criterion for determining how well the mission information has been performed, and can be used as a measure for determining how appropriately the specific disaster situation has been responded.

To this end, the score calculating unit 400 retrieves the score information previously given for each 3D virtual object constituting the virtual space, and adds the score information of the 3D virtual objects collected in the inventory UI to calculate the corresponding score can do.

In addition, the score calculator 400 may add an additional point to the corresponding score when it is determined that the location data is located within the evacuation site within a preset time limit from the time of the occurrence of the disaster event. On the other hand, the score calculating unit 400 may deduct the corresponding score if it is determined that the location data is located in the dangerous place within a set time limit from the time of occurrence of the disaster event.

Meanwhile, the score calculator 400 may assign different weights to the score information previously given for each 3D virtual object according to the type of the disaster event and the type of the mission information.

Specifically, when it is determined that any one 3D virtual object is collected in the inventory user interface (UI) during the mission execution process, the score calculating unit 400 determines another 3D virtual object previously matched with the other 3 The weight of the dimensional virtual object can be increased. For example, if it is determined that the match object is collected in the inventory, the score calculator 400 may increase the weight assigned to an object such as a lighter or paper.

In addition, if it is determined that all 3D virtual objects previously matched with any one 3D virtual object are collected in the inventory UI (User Interface), the score calculator 400 may add an additional score to the corresponding score. .

Therefore, the virtual reality-based disaster evacuation education apparatus 1 according to the present invention can not only individually determine the importance of the selected object, but also calculate the score according to the mission performance by considering the association between the selected objects together. .

Thereafter, the virtual reality-based disaster evacuation education apparatus 1 may output different result screens (end screens) according to the calculated size of the corresponding score.

On the other hand, the virtual reality-based disaster evacuation education device 1 can collect and use users' evacuation behavior pattern data according to the building structure in case of a disaster, and use it as big data.

Specifically, the virtual reality-based disaster evacuation education device 1 can simulate a disaster situation, identify the main evacuation route of users, and implement a prediction model of the evacuation route of a building through real-time location analysis. Through this, the virtual reality-based disaster evacuation education device 1 identifies the vulnerability of the evacuation route according to the structure of the building, and through log data collected from different users, the most ideal evacuation route and prediction according to the vulnerability and building characteristics Data that analyzes the behavioral direction of people in the building can be delivered to the management of the building, and used as a basic material for pre-recording evacuation broadcasts that are most suitable for each building.
