Better typing with keyboard assistive technology

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.

Better typing with keyboard assistive technology. Photo on the left shows original keyboard, with user typing with left hand. Hand is partially curled up, with index and middle fingers extended. Photo on the right shows keyboard with assistive technology to enhance typing: keyguard, angled stand, and forearm rest.

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.
