Join Gemma White and Ken Hackbarth for a virtual workshop where participants will learn how design their own highly customizable keyguard files using the Volksswitch Keyguard Customizer system. The generated files can then be 3D printed or lasercut; offering a low cost and highly accessible option for AAC users and their caregivers.

Keyguards are physical overlays placed on top of keyboards or communication devices to help individuals with motor control difficulties accurately select keys by preventing accidental key presses. They support access to Augmentative and Alternative Communication (AAC) by providing a stable, guided surface that enhances precision, thereby enabling users to communicate more effectively. An AAC app is a software application designed to assist people with speech or language impairments by providing alternative methods of communication, such as symbols, text-to-speech, or voice output, allowing users to express their needs, thoughts, and feelings.

Gemma White is an SLP with over 20 years of experience working with AAC. She graduated from the University College London as a Speech Therapist in 2000. Gemma has served on the AAC SIG12: PDC and a member of RCSLT UK. Gemma developed applications and shared her clinical expertise presenting for Apple, and numerous CE courses for SLP’s, AT professionals, including for multidisciplinary at ATIA and ASHA. She is currently the Clinical Coordinator at WIHD Assistive Technology Program and Speech Department, NY.

Ken Hackbarth is the president and founder of Volksswitch.org (now Volksswitch LLC), an organization devoted to democratizing assistive technology by leveraging the power and promise of 3D printing. Prior to his current position, he worked for almost three decades as a systems architect for AT&T Bell Laboratories and its subsequent divestitures. He has a Master of Science in Evolutionary Biology from the University of Arizona, a Master of Science in Systems Engineering from the University of Arizona, and a Master of Education in Special Education, with a concentration in assistive technology, from Bowling Green State University.

NYC Metro Makers Making Change

Makers Making Change aims to lower the barriers to assistive technology by connecting makers with assistive technology users and disability professionals to fabricate custom or available open designs. The New York City Metro Chapter is a group of volunteers supporting this mission through fabrication of devices and educational workshops.

Materials

We encourage you to follow along during this workshop. You will need the following in preparation:

Needed Software and Files

You will need a computer with the following software installed:

• OpenSCAD
• Inkscape

You will need the following files saved on your computer:

• Volksswitch Keyguard Designer files
• Screenshot file of the desired AAC app and grid layout (ensure the screenshot is taken from the device you are creating the keyguard for)

Review the Getting ready to do keyguard design video to learn how to install the needed software and set up your files and folders.

*Please note, for Mac users, you may need to right click on the software icon and select “Open” from the dropdown menu in order to bypass security features; given this software is not from an identified developer. You will only need to complete this step the first time you launch the program.
