Typing with a tongue computer interface

It’s possible to type with your tongue using tiny sensors worn in the mouth. This post presents text entry rate results from a recent study, including two people with cervical spinal cord injuries.

Image shows the 18 sensors embedded into the device, which is worn like an orthodontic retainer. Also shows how letters are assigned to each sensor to allow for typing with the tongue.
For about 30 years, researchers have experimented with different ways of typing with your tongue. The Tongue Touch Keypad from the 1990’s used a tiny keyboard embedded in an orthodontic-style retainer. A newer approach continues to use the orthodontic-style retainer, but now embeds inductive sensors that are activated by moving a small magnet attached to the tongue. How well can you type with this sort of tongue computer interface? Read on for results from a recent study.

Highlights from the ATIA 2019 Conference – Part 2

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.

Highlights from ATIA 2019 - Part 2
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!

Highlights from the RESNA 2018 Conference

The RESNA 2018 Conference featured three intense days of sharing and networking among leaders in assistive technology. It’s impossible to get to everything, but here we highlight a few things of particular interest.

I attended RESNA’s 2018 Annual Conference recently, as I do pretty much every year. This year’s was held in Arlington, VA in mid-July. A friend asked me why I invest the time and money to go to the conference. I’ll try to address that in this post, with a focus on the learning and new ideas that the conference inspires.

Evidence on computer text entry by people with disabilities

Ever wonder how quickly people can type with different accessibility interfaces? Is it useful to know the typing speed for the “average” user with cerebral palsy on an assistive keyboard?

Sajay Arthanat and I have been working together to organize the available research evidence on text entry rates (typing speeds) for people with disabilities. This has been a fun project that’s allowed us to revisit the literature published since 1986. Continue reading “Evidence on computer text entry by people with disabilities”
