Advancing universal design

This paper reflects on current practices in universal design and how they can be improved to increase adoption of the concept in mainstream design and engineering disciplines. Theory and practice in the diffusion of innovation are used to identify lessons learned in other fields that can be applied to universal design practice. Questions addressed include: How has the concept of universal design been diffused? Are these methods effective? How could they be improved? What can be done to improve adoption? How can the rehabilitation sciences, health sciences, and other disciplines help advance the effectiveness of universal design practice?
