AAC projects and policy

Published August 28, 2025 by Liz Henry

If you are interested in open source software projects for assistive tech, take a look at CBoard. It is a free/open source app for AAC (Assisted and Augemented Communication). It’s for anyone with speech and language impairments, facilitating communication with pictures and text-to-speech. You can use it to quickly construct useful communication boards, and it’s beautifully customizable. Currently, it supports 46 languages. There is a paid/subscription level to this app which makes it even more useful (and which supports the ongoing maintenance and development of the project).

If you want to learn more about the current, complicated political, technical, and social landscape of AAC, here is a list of useful updates from Bob Williams, of the organization CommunicationFIRST:

Open Source Accessibility Summit in October!

Published August 26, 2025 by Liz Henry

Coming up in October 2025, the Open Source Accessibility Summit! This is a one-day conference in North Carolina, for open source software contributors who are interested in building accessible tools and it is part of the (huge) All Things Open conference!

Do you have a passion for innovation? Do you believe everyone should be able to realize the benefits of technology? Please join us! Everyone is welcome to attend the summit. We need a diverse set of skills, experience, and perspectives.

Goals of the summit are to:

  • Make connections between people who have a shared interest in improving the accessibility of open source software.

    Share knowledge and current best practices for creating diverse, inclusive, and accessible open source projects.

    Define a public roadmap for improving the accessibility of open source software so the community can collaborate to realize it after the summit.

    Building simple switches

    Published August 7, 2025 by Liz Henry

    In the material we are scanning from Alexandra Enders’ collection of DIY assistive tech information, we have come across several great sources for learning the basics of electronics in order to make switches, buzzers, and other small gadgets, very useful for people with limited dexterity to control other devices.

    I really like these short, practical guides. Rather than having to wade through a college textbook level guide to electronics, you get just the basics you need to build very cheap and easy gadgets.

    Today’s scan is simply called “Introduction to Electric Circuits”, written in 1981 by Hugh O’Neill from the Rehabilitation Engineering Center at Stanford.

    He explains what a circuit is – an unbroken path from one terminal to another of a power source, through which current can flow. A good overview of circuits in series and parallel comes next, including the tip that most simple toy adapters the AT maker will build, will be in series.

    Types of switches covered are toggle, rocker, push button, microswitch, rotary, and mercury (tilt) switches.

    It’s a very condensed electronics course in about 15 pages! If you walk through it and try the instructions, you will learn enough about how batteries, switches, circuits, and so on work that you can build many adaptive devices.

    Adding metadata to individual device entries

    Published August 4, 2025 by Liz Henry

    The DIY information that the GOAT team has been scanning and cataloguing is in book-sized chunks right now. So, you can go to the Internet Archive to our scanned material, and search on a term — for example, “woodworking“, or “clothing” and you’ll be able to view the entire book. 

    Our goal, though, is to be able to search for individual devices. Our next project is to pull out those devices and add metadata to them. We’re testing that now on a small scale! Check out the DIY Big Index page. While there are only a few devices there for now, you may be able to see the potential! 

    We will end up with an easy way to search for every record we’ve got on how to build a standing frame, a fork extender, or a cup holder. Anyone can then comment on the designs, add photos or links to videos, and so on, to show their own builds and contribute improvements, variations, and other suggestions. 

    Those entries don’t have to be limited to information we’ve scanned. We can index and host archive copies from other sources too, and include open source software and hardware projects, like those from OpenMedTech or Open Source Wheelchairs!

    We will be hosting an event soon to invite volunteers to help us categorize and label devices. If you’re interested, please comment here or email liz@openassistivetech.org!
