Safety Experience VR Content Development Based on Diving Abnormality Response Scenario
| PROJECT | IMXR® Safety Experience VR Content - Sudden Descent |
PROJECT GOAL
| We aim to support repeated training of practical response capabilities, which are difficult to acquire through theoretical education alone, in a safe virtual environment by implementing physical conditions similar to a real underwater environment. We sought to build a platform that can also be used as a source for medical research on diving accidents through VR content for safety experience linked with biosignal monitoring. |

“By inducing a realistic state of tension, we were able to increase both immersion and data reliability simultaneously.”
I think we can measure heart rate changes by having subjects wear VR equipment. Especially by providing conditions that limit air supply in certain situations, we can induce a state of tension similar to a real diving situation. This would allow for more practical data collection beyond a simple simulation.
Overview
From experience to research, an emergency diver simulation to improve crisis handling skills
Scuba diving is a high-risk activity where immediate response to an unexpected emergency is directly linked to survival due to the unique characteristics of the underwater environment. There were limitations where existing theory-based education alone was not enough to sufficiently cultivate the quick and accurate judgment and response skills required in real underwater emergencies. Therefore, we developed an educational content that utilizes virtual reality (VR) technology to create an underwater environment similar to reality, allowing for safe experience of various emergency situations.

Immersion Strategy
This content is designed for repetitive training by creating scenarios of common emergency situations in actual diving. It is also built to be linked with a biosignal monitoring system to use data collected during training as research material for diver emergency treatment. Through this, it is expected to enable systematic and practical safety education in various fields such as diving training centers, marine rescue teams, and medical professionals, ultimately contributing to a decrease in diving accident rates and an improvement in emergency response capabilities.
Marine Extended Reality-based Simulation VR Content Structure
1. Multi-scenario integrated content
This project designed a modular scenario so that users can learn about realistic dangerous situations through experience-based training.
Scenarios will be continuously added, so ultimately, all four abnormality scenarios can be experienced. It is a modular content that realistically implements sudden situations that a real diver can face, such as air tank depletion, environmental changes, and sudden ascent/descent.
The process of preparing for diving and returning to the surface after a safety stop is the same across all four abnormality scenarios, but the abnormal situation and response method for each scenario are different. The content is designed to allow the user to experience various sudden situations in the same basic environment and learn how to respond to each situation.
1-1. Air Tank Depletion
: A diver who feels abnormal breathing checks the remaining air and confirms the rapidly decreasing air pressure. The diver calls their buddy to receive an auxiliary regulator and safely returns to the surface.
1-2. Environmental Change
: While scuba diving, the diver gets caught in a discarded fishing net, which restricts their movement. They get help from their buddy to get out of the net, remove seawater that got into their mask while struggling, and safely return to the surface.
1-3. Sudden Ascent
: While scuba diving, the diver starts floating up due to a malfunction in the buoyancy control device. They press the deflator button to release the injected air. After removing the inflator hose, they inject air with the mouthpiece along with the deflator button to safely return to the surface.
1-4. Sudden Descent
1) Diving Preparation
| 2) Descent
|
 |  |
The user learns their role by sequentially wearing diving equipment.
| The user communicates with their buddy using hand signals and operates the deflator and inflator to slowly descend.
|
3) Underwater Exploration
| 4) Ascent Attempt
|
 |  |
The user can reach a depth of 18M and explore the underwater environment.
| The user moves to a rock wall and attempts to ascend to the surface by adjusting the deflator.
|
5) Downward Current Occurs
| 6) Escaping the Downward Current
|
 |  |
The user attempts to ascend by operating the inflator, but a sudden downward current makes them sink continuously.
| The user can learn how to respond by changing direction → swimming horizontally at a 45-degree angle → exiting the current, and then controlling buoyancy.
|
7) Securing Safety and Attempting Ascent
| 8) Safety Stop
|
 |  |
The user signals their safety status and intention to ascend to their buddy. They slowly ascend while controlling their speed.
| Upon reaching a depth of 9M, they wait for 3 minutes for a safety stop as instructed by their buddy.
|
9) Diving Ends and Return
|
|
 |
|
After returning to the surface and getting their breathing in order, the experience ends with the user boarding the boat.

Marine Extended Reality-based Simulation VR Content Specialized Technology
1. Lifelike Underwater Environment Implementation
Based on IX (Immersion eXperience, Samwoo Immersion Immersion Experience), the underwater environment (underwater currents, air bubbles, marine ecosystems, etc.) was reproduced with high-resolution graphics and 3D modeling. Various environmental factors such as the flow of underwater currents, the distribution of air bubbles, and marine ecosystem elements are meticulously implemented to allow users to have an experience similar to a real diving situation.
2. Modular Structure and Research Data Utility
Developed in a modular format, each learning scenario can be operated independently. Learners can choose the scenario they want to experience from four different abnormal situations that can occur during scuba diving. In the case of 'Sudden Descent,' they can choose a scenario based on the buddy's accident response time to experience the reaction, and during this process, they can confirm changes in biosignals. The simulation of accident situations provides a foundation for using the data as research material to ensure diver safety.
3. User UI·UX Design and Real-time Interaction
By applying our standardized framework for procedural training (IMBuilder-B), the user-centric UI·UX design allows for intuitive confirmation of depth, water temperature, heart rate, and remaining air on a head-up display. With real-time interaction, situations are immediately reflected based on the diver's actions. When reaching a point of interest, directions, movement paths, and surrounding terrain are guided in real-time, and even changes in air bubbles that occur during buoyancy control are visually expressed to enhance immersion.
