The lecture discussed how to build more inclusive communities through playground design. It emphasized that inclusive playgrounds require both access and engagement. Access is about more than just physical access, but also social and emotional access through gathering spaces, spatial arrangements, and predictable, cueing environments for those with neurological impairments. Engagement is not just about access, but also ensuring activities can be measured by a user's ability rather than age and providing opportunities for individual, parallel, and group play through equipment choices that allow assessing social interaction. The conclusion was that requirements for access and engagement of those with disabilities are universal needs and inclusive design creates a space that welcomes all users.
