Koester Performance Research is a partner in the newly-funded Rehabilitation Engineering Research Center on Augmentative and Alternative Communication (the RERC on AAC). KPR’s projects focus on ensuring effective and efficient physical access to AAC for people with severe motor impairments.
Because of Covid-19, there’s a greater need for assistive technology practitioners to conduct remote assessments. This post presents a method used by occupational therapist Charlie Danger to assess for eyegaze access remotely.
Have you seen the 2019 systematic review covering assistive technology as an intervention for individuals with Rett syndrome? If not, read on for a summary of the research on assistive technology for Rett syndrome.
The ATIA 2020 conference: 2+ days packed with learning, sharing, and networking in assistive technology. Here are some highlights from my trip to ATIA this year.
Check out some KPR highlights for 2019, including our top 5 blog posts for the past year. Best wishes for 2020 to all!
After upgrading my iPad to iOS 13, my setup for two-switch scanning in Switch Control stopped working. Here’s what happened, and how I fixed it.
I recently ran into an unexpected problem getting my external switches to work when using two-switch scanning with iPad Switch Control. After wrestling with the problem and eventually fixing it (or at least finding a workaround), I thought I’d share what I learned in case it can save somebody else some time.
Here’s a quick bottom-line synopsis: If you are using a Tapio interface for two-switch input with an iPad, set your Tapio to generate 1 and 2 for outputs, rather than the Space and Enter default outputs.
Read on for more details on the problem and exactly how to implement this solution.
Morse code is an intriguing access option for people who use switches. Here’s how to measure performance when typing with Morse, to see how well it’s working for you and how it compares to other access methods.
Morse code can be an effective way to type using only one or two switches. For some people who need switch-based access due to physical impairments, Morse might work as well or better than methods such as switch scanning. Reports of typing speed with Morse in the literature are encouraging but sparse. And in the end, what matters most is how well it works for a given individual. To address that, we need to measure typing performance with Morse.
How do we do that, in a way that’s accurate, straightforward, and time-efficient? We’re going to use KPR’s Compass software for access assessment to measure our Morse typing speed and accuracy. This post describes how to do this and shows you how it went the first time I used Morse code.
The Morse Typing Trainer is a website that helps you learn Morse code. It helped me learn the letter codes in about 30 minutes. This post shows you how to use the Morse Typing Trainer and gives you an idea of what it does and does not do.
The introduction of Morse code text entry for iOS and Android has lowered the barrier for trying Morse code as an access method for people who use switches. In earlier posts, I’ve described how to set up Morse code on the iPad and reviewed the typing speeds that have been reported for experienced Morse users. But what’s a good way to learn Morse code in the first place? And how long does it take? The Morse Typing Trainer is a new resource to make this fairly easy and fun.
How fast can people with physical disabilities type when using different assistive technologies? Find out with our free AT-node for access website. Use the evidence to enhance your understanding.
I’ve mentioned our free AT-node website in other posts (like this one with a neat infographic), without really demonstrating what it is, so in this post, I want to give you a quick introduction to using the AT-node website.

Here’s another great example of how a simple change to a user’s computer setup can make a big difference, in this case using keyboard assistive technology. Read on for a summary of this 2018 case study from the University of Bordeaux.
