Abstract:
Ergonomics deals with the analysis and design of work processes. To identify ergonomically critical situations,
appropriate evaluation options have to be developed to enable an efficient analysis process. Nowadays, such
analyses are typically carried out with the help of digital models of the surrounding area and virtual humans.
These produce a multitude of geo-referenced and time-oriented data. We present a design study on how
to visualize this data to support the ergonomically analysis process optimally. As consequence of a thorough
requirements analysis and design process, we propose a novel interactive visualization which provides the user
an overview of ergonomically critical situations and their causes. Simultaneously, the user obtains the main
stress factors in a compressed form by a glyph-based visual design. Final expert interviews and a usability
study depict the utility of the proposed visualization tool.
