NSF Funding Opportunity - Research to Aid Persons with Disabilities (RAPD)

The RAPD program supports the development of technologies for new and
improved devices or software for persons with disabilities. RAPD is also
directed toward the characterization, restoration, and/or substitution of
normal functions in humans. Emphasis is placed on significant advancement of
fundamental engineering knowledge and not on incremental improvements. 
Undergraduate engineering design projects are also supported, especially
those that provide prototype "custom-designed" devices or software for
persons with mental and/or physical disabilities. The education of
undergraduate engineering students is enhanced through Undergraduate Design
Projects' awards supported by the BME/RAPD program. PIs are encouraged to
apply for supplemental funding under the Research Experience for
Undergraduates (REU) Program (NSF 00-107).
