Empowering Accessibility: Using Micro:bit and 3D Design as a Switch Interface

A Recap of the November 11th Virtual Workshop

On Monday, November 11th, 2024 we hosted a virtual workshop featuring Bill Siever and PrintLab’s Rob Mafrici. We delved into the exciting world of open source assistive technology, showcasing how the versatile Micro:bit controller can be repurposed as a switch interface to empower individuals with physical disabilities.

Why Micro:bit?

The Micro:bit, a pocket-sized computer, offers a range of possibilities for custom computer and mobile interactions. By leveraging its bluetooth and HID capabilities, we can create customized keyboard, media, gamepad, and mouse controls using on board input options. In this workshop, Bill demonstrated how to configure the Micro:bit to act as a switch sending a keyboard command using the user friendly block based coding environment Makecode. He demonstrated how to pair and set up the device to enable users to control an iPad using the OS switch accessibility settings.

PrintLab’s 3D Printed Solution

Rob introduced their innovative 3D printed case design, the Tap, which not only protects the Micro:bit but also enhances its usability. The case incorporates customizable buttons, allowing users to tailor the device to their preferences and physical abilities. The ability to easily modify the tops in Fusion360 was highlighted.

Key Takeaways from the Workshop:

• Accessibility for All: Explore how technology can bridge the gap and provide equal opportunities for individuals with disabilities overcoming cost and procurement barriers.
• Personalized Assistive Technology: Learn how to create personalized solutions using affordable and accessible tools like the Micro:bit.
• Community and Collaboration: Discover the power of collaboration and knowledge sharing within the assistive technology community and leverage this collaboration within the Maker Education movement.
