Vivelab Workplace Optimization & Ergonomic Risk Analysis

Workplace Optimization

Ergonomic Solutions

Designing the right work environment and processes for employees is a critical factor for sustainable and continuous occupational safety.

When work activities and methods are well-planned and maintained within the necessary limits, these practices prevent employees from engaging in behaviors that could lead to occupational diseases and increase productive working time.

ViveLab, a sensor-based ergonomic analysis software, helps design proper working conditions and processes in Occupational Health & Safety and

Engineering using seven different methods (RULA, OWAS, NASA, ISO11226, EN1005-4, Spaghetti Diagram, and Reachability Tests).

Instead of traditional calculation-based methods, it provides precise, targeted risk values and enables accurate ergonomic measurements and analyses.

ViveLab Sensor-Based Ergonomic Risk Analysis

During the design of ergonomic work environments, a comprehensive anthropometric database is used to ensure precise measurements. Using this database, a virtual environment simulation is created, allowing worker-machine or worker-task interactions to be modeled virtually, preventing employees from being exposed to risk and enabling the development of ergonomic solutions.

Sensor-based measurements ensure the highest level of ergonomic assessment and corrective workplace optimization, enabling a professional ergonomic analysis.

For workplace optimization, real-time ergonomic analyses are conducted using simultaneous data streams from sensors. Through the software interface, a virtual work environment is created, and professional ergonomic solutions are developed between the worker and the task based on the collected data.

RULA Analysis – ViveLab Ergo

RULA (Rapid Upper Limb Assessment) is an ergonomic evaluation method that assesses static body postures (1993, Lynn McAtamney and E. Nigel Corlett).

This method takes into account the positions of the legs, trunk, neck, arms, and hands, making it particularly suitable for evaluating postures in mechanical tasks.

The assessment outcome is also influenced by working conditions such as the load carried, the frequency of posture repetition, and available supports.

RULA evaluation uses 7 levels to score the current posture, which are grouped into the following 4 risk categories:

✅ Acceptable
✅ Action suggested soon
✅ Action required soon
✅ Immediate action required

NASA-OBI Ergonomic Assessment Method – ViveLab Ergo

NASA-Obi (Occupational Biomechanics Index) is an ergonomic assessment method based on the NASA STD 3000 (1995) standard.

This method relies on an advanced physical model that considers the torque and joint pressure of each body part.

The NASA assessment uses the following 4 risk levels to score the current posture:

✅ Acceptable
✅ Action suggested soon
✅ Action required soon
✅ Immediate action required
