Biographical Statement:

Dave Feathers conducts ergonomics research focused on inclusive design of products including wearable systems, mobile technologies, and input devices. Dr. Feathers directs the Digital Anthropometry and Biomechanics (DAB) Lab for Inclusive Ergonomic Design that uses a combination of traditional and new 3D measurement technologies to assess human-product interactions for conceptual and existing designs.  

The DAB Lab for Inclusive Ergonomic Design has the following objectives:

-   Develop and validate 3D measurements of human interaction with products among diverse populations.

-   Create digital human models/simulations of human+product interactions by gathering diverse strategies and interaction data among persons with disabilities.

-   Translate research findings to designers, consumers, and researchers to improve address health, wellbeing, physical accessibility, and safety issues.

 

There are three research foci in the DAB Lab for Inclusive Ergonomic Design: 

ARIA (Arthritis Research for Inclusive Actions): To assess and improve the products used on a day-to-day basis by millions of individuals with arthritis. 

Wearable Technologies: Modeling Fit, Interactions, and Usability: To understand and address ergonomic issues for wearable technologies, including passive and active systems.

Inclusive Work: Mobile Devices and Input Devices:  To provide an evidence-base for inclusive design of workplace products.

All areas of research use both traditional and 3D measurement technologies to assess human+product interactions in 3D space over time.  Research focuses on personal strategies, compensatory behaviors, and use (or non-use) of products features.

Current Research Activities:

Inclusive Design to Support the Active Arthritic Hand:

       -  Physical modeling of individuals with osteoarthritis and rheumatoid arthritis.

       -  Dynamic modeling of hand grip and pinch strength.

       -  3D modeling of physical interaction with products including wearable assistive technologies.

 Outcome: An international database of measurements and functional modeling to support hand-intensive activities for persons with hand arthritis. 3D and 4D data is used in CAD environments to support designers and engineers as they develop new products for this large and growing population.

Inclusive Design of Handheld Multitouch Products: Biomechanical Modeling:

-  Physical interaction research on the structural hand and gesturing hand for healthy and arthritic populations. 

-  Current data collection efforts use a quasi-static approach and motion tracking data of the upper extremity to model and simulate multitouch tasks.

Outcome: New methods to understand multi-touch input control and gesture-based commands.
