N1 - Funding Information: The authors would like to thank Dr. Deborah Alperovitch-Najenson of the Department of Environmental and Occupational Health, Sackler Faculty of Medicine, Tel-Aviv University; and Prof. Moshe Ayalon of the Biomechanics Laboratory, Zinman College of Physical Education & Sport Sciences, Wingate Institute, Netanya, Israel, for their professional support. Thank also to Prof. Alon Wolf and Oded Solomon, of the Biomechanics laboratory, Technicon - Israel Institute of Technology, for their assistance in the motion- capture laboratory and experiment. The authors would also like to thank Oshri Even-Zohar, for creating the custom software module in the Autodesk's XSI 3D package. This module was used for the real-time cloud visualizations described in this paper. Funding Information: Ranit Eldar (PhD) is a researcher, ergonomics expert, industrial designer and university lecturer. She received her Ph.D. degree from the Faculty of Architecture and Town Planning at the Technion-Israel Institute of Technology, in collaboration with the Faculty of Medicine at Tel-Aviv University, and the Faculty of Biomechanics at the Wingate institute, Israel. Running her own company, ERGOTECH-Industrial Design and Ergonomics ( https://ergotech.co.il ), Ranit combines theoretical and experimental ergonomics studies with design project for numerous global organization. She has won international prices, and has worked in collaboration with R&D institutes in Europe, and with the chief scientist of the United States army; her research and products are utilized around the globe. Dafna Fisher-Gewirtzman (PhD) is an assistant Professor in the Faculty of Architecture and Town Planning at the Technion-Israel Institute of Technology, and a visiting scholar at CUSP-NYU.

N2 - Ergonomic models and techniques are a fundamental issue in the design of comfortable and safe products and spaces. User studies, related to visualization tools are current issues in the ergonomics and design visualization literature. But researchers have begun to discover that user study is rarely straightforward, especially when drawing visualization data from interdisciplinary sources. The availability of a plethora of visualization techniques can make it difficult to determine the most appropriate technique to convey maximum possible understanding. The RT-MHV (“Real-time”– “Motion history volumes”) 3D computerized assessment model, developed by the authors, demonstrates a local risk evaluation of work-related musculoskeletal disorders (WMSDs), based on real-time and on motion history volumes. With the model, the visual display of the WMSD risk level for each body segment is defined by color-coding at points surrounding an avatar's segment, representing an actual user. The values associated with areas with an increased risk of WMSDs can be identified and iterated quickly, so as to determine the “optimal posture”. Designers can share this knowledge by recording the user's postural interactions, defined through the mapping of geometric comfort data and WMSD risk level categories. The challenge in the development process was to overcome existing “gaps” between ergonomics data and designer requirements. Further research on the RT-MHV model is recommended, principally for developing stand-alone CAD software. An aggregated statistical information database and complete body joints visualizations will be computerized in due course. 2D tabulation and statistical information relating to body joints will be made available on demand.
