Raymond Lowey once said, ‘Design is too important to be left to designers’. As an industrial designer and educator trained in the 1980’s, and with over 25yrs experience in the classroom, I can attest to the fact that all these years later designers are still taught to be the lone creative genius. Of course, they are encouraged to research and talk to experts and users and inform their designs with knowledge beyond their own, and some of them work in multidisciplinary teams, but the creative act is jealously guarded as being the sole prerogative of the designer. In this letter I will lay out an alternative way of designing, one in which the creative effort is shared and owned by a group of stakeholders with differing and essential perspectives on the needs to be addressed. This letter will focus in particular on how designers co-create with people with disabilities and clinicians to produce Adaptive Designs that meet the custom needs of an individual co-creation partner. Collaborative design (co-design) or co-creation is not a new concept. However, I suggest that there is an opportunity to more deeply ground theories of equitable co-creation in immersive engagement with people with disabilities as key partners in the design process.
