Still, there are many real and perceived barriers to innovating for disabilities. One of the problems Mitchell hears most often from companies is that they don’t know how to reach enough people with disabilities to test a product. She urges companies to partner with universities to design, create and test new products. University research departments often have long lists of potential focus-group participants who could serve as product testers. And, Mitchell continues, schools also have labs and R&D groups that are far cheaper to hire and staff than creating a private lab. Another option is to partner with veterans’ groups, as many war veterans have acquired disabilities.
