Biographical Statement:

Dave Feathers conducts ergonomics research focused on inclusive design of spaces and accessible products.  The goal of his work is to reduce disablement through research and design.  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-environment and human-product interactions for conceptual and existing inclusive designs.  

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

Develop and validate 3D measurements of human interaction with the physical environment among diverse populations.

Create digital human models/simulations of human+product+environment 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):  

Aim: To assess and improve the products and environments used on a day-to-day basis by millions of individuals with arthritis. ARIA uses both traditional and 3D measurement technologies to assess human+product+environment interactions in 3D space over time.  Research focuses on personal strategies, compensatory behaviors, and use (or non-use) of products or environmental features.

PACE (Physical Accessibility in Care-centered Environments):  

Aim: To understand and address physical barriers to healthcare delivery that may lead to disparities among persons with disabilities. PACE research has investigated healthcare-centered environments, including access to primary care, home healthcare, diagnostic machinery, portable multi-touch medical devices, personal protective equipment, and hardware products that promote human health and wellbeing.

Inclusive Workplace Products and Environments:  

Aim: To provide an evidence-base for inclusive design of workplace products and environments. The DAB Lab has developed and validated new research methods to study physical accessibility for 3D interactions with products used in the workplace.  Inclusive designs for office and learning environments are areas of ongoing research.

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.

 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 and environments for this large and growing population.

DIEM: Improving Daily Interactions for Older Individuals with Arthritis:

-  The Cornell DIEM (Daily Interaction with the Environment Method) is a tool to assess the individual’s home environment, personal functional capacity, and task interaction.

-  Research in the measurement and validation of 3D and 4D measurements of person/environment interactions address physical accessibility and human performance for activities of daily living.

-  Biomechanical modeling of the upper extremity of persons living with chronic pain performing daily activities.

Outcome: Address environmental barriers through intervention research that optimizes human performance for persons with chronic pain from arthritis.

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 for domains such as electronic medical charting.

 Physical Access to Healthcare Environments Across the Lifespan:

-  Assessment of healthcare environments for persons with physical disabilities across the lifespan.

Outcome: A sample of environments surveyed, measured, and modeled for three cities in the Northeast United States.
