Combining Motion Capture and Traditional Ergonomics Analysis Tools
About this good practice
In SEAMK a new wearable motion capture system is used to enhance the assessment of physical workload in real working environments. This approach provides a more visual and intuitive way to demonstrate traditional ergonomic analyses.
Traditionally, methods like OWAS and RULA are used as ergonomic analysis tools, based on visual observation. Video recordings can help revisit postures for more accurate estimations, but motion capture technology offers more detailed data.
Perception Neuron Studio system by Noitom was adopted to support this. It uses 17 sensors attached to key body parts, detecting movements through gyroscopes, accelerometers, and magnetometers. Data is transmitted wirelessly to a computer running the Axis Studio software.
The key innovation was integrating Axis Studio with Siemens Process Simulate, a tool for ergonomic analysis. This integration allows the creation of a real-time virtual avatar replicating the user’s movements in normal working environment. The software enables RULA and OWAS assessments directly from the captured motion data. It also offers visual feedback to identify high-risk postures easily.
Visual feedback proved highly impactful: employees can see their own posture in real time, which leads to better awareness and discussions about improving ergonomics. It encourages the use of assistive tools, adjustments to workstations, or changes in work methods. The participatory approach results in concrete steps toward more ergonomic work practices.
Resources needed
Infrastructure:
- Hardware and laptop (Noitom Perception Neuron Studio)
- Axis Studio software and Process Simulate -tool
- Cameras
- companies who are willing to analyse ergonomics and workloads of the employees
Human resources:
- Technical staff
- Ergonomics specialists
- Researchers and analysts
Evidence of success
The method has been applied to 13 companies in metal, construction, and care sectors. A total of 57 tasks were measured in real working conditions. The model received highly positive feedback from the workshops held for companies, where visually recorded tasks were presented with improvement suggestions to enhance work ergonomics. Integrating the motion capture system with traditional ergonomic analysis tools is unprecedented solution, which has proved to be highly effective and illustrative.
Potential for learning or transfer
The method is transferable to all parties interested in the added value that motion capture brings to ergonomics analysis. The application of motion capture introduces a new dimension to the field of ergonomics. It allows work tasks to be presented in a highly visual, concrete, and illustrative way, enabling the employee to see their own performance from an external perspective and identify any improper movements or incorrect postures. Seeing one's own performance provides a new perspective on improving one's work ergonomics.
