Method Development
As dynamic anthropometric data becomes more readily available, the future of anthropometry has the ability to influence innovation at the critical intersection of ergonomics and the sizing and fit of advanced wearable products.
Overview
Dynamic Anthropometry
The Human Dimensioning Lab develops new methods to use dynamic anthropometry to encourage more robust, data-driven design development for products in need of lifesaving innovation. Our research transforms the frontiers of human factors and wearable products by enabling the measurement of complex dynamic surfaces. Through merging body-product knowledge with material science innovation, future dynamic data will be a catalyst for innovation in wearable product development. The human dimensioning lab will continue to extend their research ability to quantify dynamic fit of wearable products, advance product knowledge in performance biomechanics by capturing the quantity and mechanics of two surfaces exerting force during movement, inform safety protocols for PPE and other wearable products, and enhance collaboration between a range of disciplines. The future in this space will help define and shape new paradigms of research and will improve the capacity to develop wearable products for medical, space, and beyond.
3D Hand Scanning
Over the last 4 years, in collaboration with researchers at the University of Oregon, the HDL has demonstrated a true need for detailed analysis of static and dynamic hand measurements. In 2019, the HDL team created a first of its kind large-scale 3D hand anthropometric database with over 800 hand scans. The database includes multiple types of data; 1) population information, 2) participant hand history and glove fit issues, 3) manual measurements, and 4) two scanned hand positions with landmarks.
Exploring the application of new 3D hand data has been a top priority of the lab. New technologies such as 3D simulation and digital prototyping offer endless design opportunities for gloves and hand tools. One potential application is digitally draping, which can be used to improve glove fit.The HDL anthropometric data and design research will inform functional glove and tool design for a range of fields and consumers.
Featured Projects
Dynamic Anthropometric Assessment of the Waist-Hip-Thigh
Kimberly Clark Corporation
The purpose of this study was to develop an integrated landmarking method to analyze waist-hip-thigh scans captured with an Artec Leo handheld scanner. Analyzing dynamic shape change of the body and product performance requires the integration of the scanning technology and new landmarking methods. This integration quantifies the shape of the body by using 1D, 2D, and 3D measurements to capture the 3D complexity of the body. Understanding percentage changes of the body in different positions can suggest data-based design decisions for products to act as a second skin.

4D Dynamic Surface Capture Research: Exploring New Frontiers in Advanced Wearable Product Development
Grant-In-Aid, University of Minnesota
The purpose of this study was to collect and analyze data from the 3dMD 4D System, and create a model for how to use 4D data in future wearable product design research. The 4D full-body system captures and generates a series of 360-degree true anatomical body models over a period of time. 4D scanners have the ability to collect traditionally “hard-to capture” parts of the body like hands, while incorporating dynamic motion.

3D Anthropometric Hand Assessment and Glove Design for Occupational Workers
Agriculture Experiment Station
The purpose of this research is to conduct a dynamic, 3D anthropometric survey of hands to build a database of scans that can then be measured and analyzed using a consistent methodology. This will include detailed ergonomic and anthropometric analysis of the hand in dynamic positions. To date, we have created a database of over 600 participant hands.
