NEC Enhances 'NEC Digital Twin Human Work Log & Analysis Solution' Based on Field Feedback

NEC today began offering a new version of its 'NEC Digital Twin Human Work Log & Analysis Solution,' incorporating feedback from the field to include support for mixed-model production and efficiency improvements for setup and deployment.

This solution records manual work via video, visualizing work flows, variations, and differences. By grasping actual work conditions as facts, it supports solving issues such as productivity and quality improvement, and skills transfer. With this enhancement, the solution's applicability to diverse manufacturing sites has been expanded, making it easier to use continuously in the field.

Key Enhancements Based on Field Feedback:
- Ability to switch and analyze patterns with different work content, enabling use in mixed-model production sites.
- Streamlined preparation work for teaching AI work content, reducing the burden during introduction and deployment.
- Flexible selection of detection for work omissions and procedural errors based on actual site conditions.
- Refreshed UI for improved operability and clarity, further enhancing convenience for continuous use.

[Background]
In recent years, the importance of high-mix low-volume production has increased in the manufacturing industry to meet diversifying needs. On the other hand, due to aging and labor shortages, in processes that rely on human work and judgment, such as inspection and assembly, actual work methods and procedural differences are not sufficiently visualized, leading to cases where quality variations and improvement points cannot be fully grasped. Many voices from the field say, "I don't know why the variation occurred" or "It's hard to find improvement points."

Under these circumstances, there is growing expectation for initiatives that visualize and digitize work and judgment that have relied on people using AI, allowing actual site conditions to be grasped as facts, clarifying variations and procedural differences, and facilitating considerations for standardization and quality improvement. In response to these challenges and feedback, NEC launched the 'NEC Digital Twin Human Work Log & Analysis Solution' in May 2025. Since then, through introduction considerations and business negotiations, many requests emphasizing actual operation aspects have been received, such as "I want to use it in mixed-model production sites" and "I want to keep using it while suppressing daily operational burdens."

[Features of this Solution]
1. High-precision detection of work omissions and procedural errors
Detects procedural errors and work omissions in real-time and notifies managers, enabling rapid response. This is achieved by NEC's proprietary video analysis technology, which captures subtle finger movements and identifies dozens of types of manual work with high precision.
2. Find waste and unevenness in a short time, leading to daily improvements
Identifies the start and end of work from the worker's hand movements and automatically measures cycle time. Visualizes cycle time variations, allows pinpoint checking of recordings for slow cycles, and enables quick identification of the causes of waste, unevenness, and stumbling blocks.
3. Visualize the tricks of skilled workers and support skills transfer
Supports the creation of a mechanism to pass on skills without difficulty, even in sites with labor shortages and aging. Records hand trajectories and allows side-by-side or overlaid display of hand movements of skilled workers and less experienced workers for comparison.
