Morse code has been used in assistive technology since at least the 1970’s to support typing using one or two switches. This post summarizes what we know about typing performance for Morse code users with physical disabilities, and how it compares to other switch-based text entry methods.
Morse code can be an effective way to type using only one or two switches. It’s been around for decades as an assistive technology (AT) that can be used by people with high-level spinal cord injuries (often with a sip/puff switch), severe cerebral palsy, or other conditions that cause significant physical impairments.
This post was inspired by a question sent to the RESNA AT-FORUM listserv by Craig Wadsworth of the Illinois AT Program and Debra and Thomas King, long-time advocates of Morse code. They are trying to gather info from people who are using Morse or have helped someone use it, in order to build a firmer knowledge base about using Morse effectively.
Their question got me thinking about what we really know about the viability of Morse relative to other switch-based methods such as switch scanning.

The ATIA Conference provides great opportunities for learning, sharing, and networking in assistive technology, and the 2019 conference was no exception. Here’s the second of two posts featuring a few of the highlights.
I was fortunate to attend ATIA’s 2019 Conference recently, held in Orlando, FL, and enjoyed the chance to learn from others and connect with the great folks who work in the assistive technology (AT) field. My first post on ATIA 2019 focused on highlights directly related to mouse access, while this post will highlight some educational sessions that addressed other topics. Keep in mind that with about 400 presentations, 120 exhibitors, and 3000 attendees, this is just one tiny sample representing one person’s ATIA experience. Please share comments about your ATIA experience!

2018 was an unusual, fun, and interesting year for Koester Performance Research. Here are some highlights of KPR’s work in the past year.
Wishing you all a Happy New Year! In the spirit of a new year’s energy, I took a look at KPR’s activities in the past year. 2018 was unusual, in that we’ve intentionally not been engaged in a large funded project, in order to leave some space and see what might take shape. One overarching goal this year was to share more of what we’ve learned and developed with the wider world. To that end, we revamped the KPR website, incorporated a blog, and set up new systems for communicating with people who are interested in what we’re doing. It’s still a work in progress, but has been enjoyable and seems useful so far. We also continued research, development, and service work within assistive technology. Read on for a few specific highlights.

Continuing our series on examining text entry rate data for people with physical disabilities, we look today in more depth at the statistical distribution of those data. A histogram is a great tool for visualizing a distribution and providing insights into a dataset.
As promised in our previous post, today we’re going to delve more deeply into our dataset of text entry rate across 177 individuals with physical disabilities. (If you haven’t seen the infographic and read about the creation of this dataset already, you might want to read that earlier post first.)

We gathered the available data on computer text entry by people with physical disabilities and created this infographic. Results suggest that there is a long way to go to better support computer users with disabilities.
Sajay Arthanat and I continue organizing the available research evidence on text entry rates (typing speeds) for people with disabilities. I shared an overview of the findings in an earlier post. Here, I’ve added two new studies to the dataset and created an infographic describing the distribution of text entry rate across 177 individuals.
