Research on measuring divers' bio-signals during underwater activities is still limited. However, if divers' physical behaviors and bio-signal changes can be observed and analyzed in real-time, more effective emergency response and safety assurance can be achieved in accident situations.

Since research systematically analyzing physical responses and anomalies in diving environments is limited, there is a need to secure empirical research data to quantitatively observe and analyze these factors.



SOLUTION

  • VR Simulation-Based Training : Reproduces real accident scenarios in a virtual environment to monitor diver behavior and bio-responses.

  • Securing Quantitative Research Data : Utilized as research data for improving diver safety manuals and policies.

  • Applications in Research, Education, and Industry : Applicable to various fields, including VR training programs, research projects, and industrial safety management.



Marine Extended Reality Based Simulation VR Content Composition

The sudden descent simulation VR content begins on a boat in the middle of the ocean. The user wears safety equipment for diving and experiences scuba diving as a beginner diver. Through a HUD displayed in front of the user, they can intuitively check the changing environmental and bio-signal data such as heart rate, depth, water temperature, and remaining air supply. Through interaction with a buddy, users can experience safe scuba diving and learn how to respond to downward currents.


1. Diving Preparation2. Descent
Before entering the water, users wear a sensor vest, sensor belt, buoyancy jacket, diving computer, and mask in sequence, learning about the role of each piece of equipment.Before diving, users use hand signals at the surface to communicate their intent to descend to their buddy. They operate the deflator and inflator of the buoyancy control device to descend slowly.
3. Underwater Environment Exploration4. Ascent Attempt
Upon reaching a depth of 18 meters, users can explore the seabed environment.Users move to a rock wall and adjust buoyancy with the deflator to attempt ascending to the surface.
5. Downward Current Occurrence6. Downward Current Escape
While attempting to ascend using the inflator, a sudden downward current causes the user to sink further. The HUD displays heart rate and remaining air, and as the heart rate increases, air consumption accelerates, creating a sense of urgency to ascend quickly.With guidance to escape the downward current, users learn response methods in the sequence of changing direction → swimming parallel at a 45-degree angle → escaping the current, followed by buoyancy adjustment.
7. Ascent Attempt After Securing Safety8. Safety Stop
After escaping the current, users communicate safety status and ascent intent to their buddy via hand signals. They press the inflator and deflator buttons to adjust speed and ascend gradually.Upon reaching a depth of 9 meters, users follow the buddy’s instructions to perform a 3-minute safety stop, a critical procedure to release residual nitrogen before returning to the surface.
9. Return After Dive Completion

After returning to the surface and regulating breathing, the experience concludes with the user boarding the boat.



Specialized Technologies for Marine Extended Reality Based Simulation VR Content


Based on user-centered design, this content is structured to allow users to explore the diving environment and acquire information in their preferred way. Real-time interaction and immersive environmental representation enable users to actively respond to accident scenarios while wearing diving equipment and observing the marine environment.

1. Vivid Marine Environment Implementation

Based on IX (Immersion eXperience, Samwoo Immersion Experience), the marine environment (underwater currents, air bubbles, marine ecosystems, etc.) is reproduced with high-resolution graphics and 3D modeling. Various environmental factors, such as the flow of underwater currents, distribution of air bubbles, and marine ecosystem elements, are meticulously implemented to provide users with an experience similar to real diving situations.

2. Vive Pro Eye Optimization

Developed specifically for the Vive Pro Eye device, this VR content operates with a high-performance PC connection. It supports precise location tracking using base stations and enables gaze-based interaction and gaze data analysis through eye-tracking functionality. These device-specific features provide an advanced VR experience suitable for professional use in corporate, research, and training environments.
 


3. Modular Structure and Research Data Utilization

Developed with a modular structure, each learning scenario can be operated independently. Users can select from four anomaly scenarios that may occur during scuba diving. In the case of "Sudden Descent," users can choose scenarios based on the buddy's response time to accidents and experience changes in anomaly signals based on bio-signals. Accident scenario simulations provide a foundation for research data to ensure diver safety.


4. User UI/UX Design and Real-Time Interaction

Applying the proprietary standardized IMBuilder-B framework for procedural training, the XR-based user-centered UI/UX design allows intuitive monitoring of depth, water temperature, heart rate, and remaining air through a heads-up display. Real-time interaction functions reflect the diver’s actions immediately.
Upon reaching exploration points, directions, movement paths, and surrounding terrain are guided in real-time, with visual representations of bubble changes during buoyancy adjustment to enhance immersion.
