Anthropometry of Wheeled Mobility Project: Final Report

This depicts knee and toe clearance required by manual chair users for forward approach to elements in the built environment (e.g., countertops). It references dimensions of clearance height and depth to the dorsal foot point on a person (e.g., top of ankle). Shaded areas depict the envelope of space required by the specified percentage of people if positioned with the dorsal foot point touching an obstruction. Hence, to accommodate a particular percentage of users, the side profile of a design element (shown by dotted line) should not extend outside the corresponding shaded area.
