简要总结
This study focuses on the design and evaluation of an innovative training protocol aimed at working at heights in the construction sector in the city of Cali. The main focus of this protocol lies in the use of Immersive Virtual Reality (IVR) and the measurement of biosignals to enhance workers' safety and preparedness. The training protocol is developed by creating virtual environments that simulate hazardous working conditions, allowing workers to practice high-risk situations safely and effectively. Additionally, the integration of biosignal measurements, such as heart rate variability and respiratory rate, is used to assess workers' stress levels and decision-making abilities during simulations.
The protocol evaluation is conducted through a pilot study with real workers in the construction field. The results are analyzed to determine whether the use of IVR and biosignal measurement improves assertiveness and, therefore, safety, reduces workplace accidents, and increases workers' confidence in high-risk environments. The findings of this study will provide valuable insights into the effectiveness of IVR and biosignal measurement as training tools in the construction sector, which could have a significant impact on reducing workplace accidents and injuries. This innovative approach has the potential to enhance occupational safety and workers' preparedness in high-risk environments, thereby contributing to a safer and more efficient working environment in the construction industry.
详细描述
Safety in the construction sector is of vital importance, especially in high-risk activities such as excavations and working at heights. To improve worker training and preparation in these areas, this research proposal has been developed.
This project focuses on the use of advanced technology, such as Immersive Virtual Reality, to simulate real work situations and allow workers to practice and acquire the necessary skills to face the challenges of their daily tasks. However, what makes this project particularly interesting is the incorporation of biosignal measurement during training.
Biosignals are physiological indicators that can be measured and analyzed to assess an individual's emotional and physical state. In this context, devices will be used to capture data such as heart rate, respiratory rate, and their variability. These measurements will provide precise information about the worker's reactions to different simulated situations, which will, in turn, help identify areas for improvement and optimize the training protocol.
The main contribution of this project lies in generating new knowledge about how biosignals can be used as a complementary tool in the design and evaluation of training protocols for workers in high-risk activities. The information obtained through biosignal measurement will allow for the identification of patterns and trends that will help better understand workers' physiological and emotional reactions, as well as their performance in critical situations.
This clinical trial compares two training methods for workers at heights, one using Immersive Virtual Reality (IVR) in addition to the conventional training, and the other using only the conventional training. The main questions to be answered are:

盲法说明
The analysts who perform the statistical analysis of the data will be blinded to the group assignments of the participants. This means that they will not know which participants received the immersive virtual reality training and which received the standard theoretical training. During data collection and management, the data will be anonymized and coded to prevent any identification of the participant's group assignment by those handling the data.

PRACTICAL SKILLS FOR WORKING AT HEIGHTS
时间窗: The time frame for completing all practical activities, assessments, and evaluations is approximately 10 hours, distributed over 2 days.
Each activity is scored on an approve/disapprove system. By the end, workers must meet these standards: 1. Harness Donning and Adjustment: Properly don, adjust straps, and ensure no slack. Passing requires a secure, comfortable fit and correct anchor positioning. 2. Anchor Points: Select/install anchors compatible with the system and load standards. Passing requires secure installation verified by testing. 3. Lifelines: Use vertical/horizontal lifelines, maintaining connection. Passing requires constant security. 4. Climbing/Moving: Safely ascend/descend while connected. Passing requires proper system use and controlled movements. 5. Tool Handling: Secure tools to prevent falls. Passing requires consistent adherence to safety protocols. 6. Emergency Response: Simulate emergencies calmly, following protocols. Passing requires appropriate stress management. 7. Equipment Inspection: Identify equipment issues. Passing requires thorough inspection and defect reporting.
次要结局
- Respiratory Rate Variability(Respiratory rate variability will be assessed over an approximate period of 45 minutes.)
- Heart Rate Variability(Heart rate variability will be assessed over an approximate period of 45 minutes.)
- Ergonomic Analysis of the Activity(The REBA score will be assessed over an approximate period of 25 minutes during the observation of the occupational task.)
- Attention and memory measurements(Before the training protocol)
