These Accessible Buttons Help a Four-Year-Old Use a Computer

The difficulty in designing and mass-producing accessible devices is that, by their nature, they need to be tailored to the individual. Two different people living with the exact same limitations may benefit from very different solutions. That’s why Wichita State University’s Assistive Technology program gives students the responsibility to design devices customized to individuals, as they did with these buttons created for a four-year-old client with cerebral palsy.

When the WSU Assistive Technology team gets assigned a project, they take the time to work with the client or their guardian to learn about what elements might have the biggest impact. In this case, there were five key requirements: Bluetooth connectivity, multiple switch inputs, easy remapping for future-proofing, strong visual accessibility, and physical reachability.

The solution they came up with is clever in its simplicity and perfectly suits the client’s needs.

It works with either an Arduino Nano ESP32 or...
