The Visualization of Human Function for Use in Environmental and Product Design

By Jenkins, Gavin R., MA, ATP, OTR; RESNA 28th International Annual Conference 2005: Atlanta, Georgia,
Publication Date: 2005

Paper discusses the integration of digital human models with three-dimensional visualizations of products and living spaces, which can allow for real-time simulations and interactions as well as advanced performance testing for environments and products designed for people with disabilities. Motion capture technology was used to create models of people with disabilities that accurately portray the details of peoples’ functional abilities in order to provide accuracy in the design process. The project utilizes an optical measurement hardware system and the Track Manager system from Qualysis. This system uses a 360-degree array of Motion Capture Unit digital cameras, which emit infrared light reflected from low mass, retro-reflective targets positioned on the person to capture the position of the targets with high spatial resolution. Visual feedback is captured by connecting a video camera to the system and presenting a synchronized video image along with the acquired data. The motion capture and video data can be compared and contrasted to determine and validate how accurate the motion capture is in providing a representation of a person with a disability. The author contends that this could provide researchers with a valuable tool in helping designers to make informed decisions regarding design issues in terms of accessibility and usability for people with disabilities and people who are older. This paper was presented at the 2005 annual conference of RESNA, the Rehabilitation Engineering and Assistive Technology Society of North America and is available on CD-ROM.
