Most of us factor in technology literacy and competence when we develop. WE want things to be as intuitive and “user-friendly” as possible. But for those aging into disabilities, learning computers can be a process of re-learning with a daily changing brain. Where do the aging brain and the aging mind intersect online and how does your app or website deal with neuroplasticity in the aging user? How does neuroscience figure into digital accessibility to help us train seniors to access assistive technology? Knowledge we presume someone has may not be there or may be different day-to-day. This talk will focus on assistive technology training practices, such as task-based training, step-by-step training, and how these training models intersect with websites you are building, or apps you are testing. WCAG2.1 covers a lot, but gaps are emerging in how we design for those aging into disability, and how you develop, and how we train need to meet soon, or the silver tsunami will continue to face more access barriers to technology, on top of perception-based barriers like fear and lack of training that they already encounter.
