Evaluating the effectiveness of universally designed environment is typically done through
case studies conducted by experts in field settings. The logistics and costs associated with field case
studies, however, inevitably constrain not only the individuals who can participate, but also the
environments that can be studied - further compromising case studies’ already limited generalizability
and frustrating evidence-based universal design practice. This chapter discusses an alternative standard
for evaluating the effectiveness of universally designed environments that removes these constraints
and enhances case studies’ generalizability by moving them from the field to the internet.
