Design Guidelines for Wheeled Mobility Accessibility

The primary purpose of this website is to disseminate our research findings about the sizes, abilities and space needs of contemporary wheeled mobility device users in the form of visual, interactive design aids.

These design aids are intended to provide technical assistance to accessibility standards committees, government officials and designers to help improve accessibility to the built environment by wheeled mobility users.

The anthropometry research for the wheeled mobility database was initially funded by the the U.S. Access Board (contract # TPD-ABA-07-C-001) and NIDILRR (grant #H133E99005).
