How to measure performance when typing with Morse code

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.

AT-node: explore the data on typing with assistive technology

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.

KPR highlights for 2018

2018 was an unusual, fun, and interesting year for Koester Performance Research. Here are some highlights of KPR’s work in the past year.

KPR wishes you a Happy New 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.

Which hands-free mouse is right for you?

Once you’ve identified a few hands-free mice that seem to meet your needs, how do you find the one that is the best fit?

Hands-free mice: Which is right for you?
Here’s the third in our series on hands-free mice. We’ve looked at 13 considerations for choosing a hands-free mouse, then examined detailed features of 25 available hands-free mice. All that information is useful for narrowing down the choices and identifying a few candidates that might meet your needs. In this post, we look at how to find the “right” solution from among those candidate devices. To support an evidence-based decision, we’ll show you some tools that help collect and organize data while trialling different hands-free mice.

Better mouse control with Pointing Wizard

Here’s a quick example of how Pointing Wizard helped Linda use her mouse with greater ease and speed. View her mouse control before and after using Pointing Wizard to customize her mouse settings to her specific needs.

Pointing Wizard: for better mouse control

Meet Linda

Linda’s story demonstrates that a simple change to a user’s computer setup can make a big difference. Linda is a woman who had a brain injury a number of years ago. The injury left her with significant physical difficulties in walking, speaking, and using her hands. She uses a Windows computer for all kinds of tasks, with the typical keyboard and mouse.

Although Linda uses a standard mouse, it’s not easy for her, as she often overshoots the target, and bounces back and forth a few times before settling on the button or field that she’s trying to click. Read on to see how KPR’s Pointing Wizard software made it much easier and faster for Linda to control her mouse.

Scanning Wizard: using auditory scanning

Auditory scanning can be useful to support users who have difficulty seeing or reading. Learn about the auditory scanning feature that we’ve recently added to Scanning Wizard.
