Hida Lab
Machine-translated · View original
A lab that seeks to harmonize comfort and work efficiency in the workplace.
AboutAbout the lab
Harmonizing workplace comfort and work efficiency.
The Hida Lab is an industrial ergonomics lab that measures and evaluates the physical strain placed on workers' bodies.
Ergonomic assessment tools that rely on human visual judgment have problems: they require knowledge and effort, and results vary between evaluators.
To address this, the lab is developing a system that estimates joint positions from videos of work and automatically evaluates posture using machine learning.
It aims to harmonize "comfort" and "work efficiency" in the workplace.
Key terms
- Ergonomic assessment tool
- A method that judges how work is performed against set criteria to estimate the need for improvement and the risk of low back pain
- Industrial engineering
- A field of engineering that analyzes the flow of people, materials, and time to improve how work systems operate
- Pose estimation
- Calculating the positions of a person's joints from images or video

ResearchResearch themes
The lab measures the physical strain that work places on the body at work sites, using ergonomic assessment tools. By automating these assessments, it works toward improvements that achieve both comfort and work efficiency.
*Illustrative imageAutomatically evaluating work posture
The lab proposes a method that estimates joint positions from camera video of work and automatically assigns posture evaluation scores with a machine learning model. The aim is to reduce the knowledge and effort required for visual assessment, as well as the variability between assessments.
*Illustrative imageReducing physical strain
To prevent work-related problems such as low back pain and stiff shoulders, the lab measures postures that put heavy strain on workers at work sites and compiles the results into data. It also examines work methods and staff assignment that take physical strain into account.
