Why not design a system using brain wave reading to operate a palm sensitive output system readily read by the display. More specifically, you think of what you wish to write, this is read out of your brainwaves and then sent to your hand to provide to the display. Your reaction to the output then determines corrections and deliberate insertions and deletions.
What its intriguing with such an scenario is that it fully engages mind and hands to produce clear text as quickly as possible. Better you have both brain wave induced correction as well as palm induced corrections and last but not least forced corrections as needed.
I personally write a paragraph in my head and then pound it out. Having it immediately appear would allow proofing to start then and that is a vast improvement in productivity. Mind to screen configuration needs exactly this type of interactiveness.

Ultrasound makes for palm-based computer displays you can feel

Researchers at the University of Sussex are
working to augment palm-based displays by adding tactile sensations to
the mix.
From buzzing phones to quivering console controllers,
haptic feedback has become indispensable in modern computing, and
developers are already wondering how it will be felt in systems of the
future. Sending ultrasound waves through the back of the hand to deliver
tactile sensations to the front might sound a little far-fetched, but
by achieving just that UK scientists claim to have cleared the way for
computers that use our palms as advanced interactive displays.
For years now scientists have been chipping away at the idea of using human skin as a computer display. It sounds unlikely, but with technology becoming more miniaturized, the uptake in wearable devices and more time spent gazing into computer screens, in some ways it seems natural that we use our most readily available surfaces as gateways to the digital realm.
While we're not expecting the very next Fitbit to project your calories burned onto your forearm, some promising prototypes have emerged in this area. The Skinput display system from 2010 used a bio-acoustic sensing array to translate finger taps on the palm into input commands, while the Cicret wristband concept from 2014 envisioned beaming an Android interface onto the arm and used proximity sensors to follow finger movements.
Researchers at the University of Sussex are working to improve palm-based displays by adding tactile sensations to the mix. Importantly, they are aiming to do so without using vibrations or pins, approaches they say have plagued previous efforts as they require contact with the palm and therefore disrupt the display.
So they are looking to sneak in the back door. Their SkinHaptics system relies on an array of ultrasound transmitters that when applied to the back of the hand, send sensations to the palm, which can therefore be left exposed to display the screen.
The team says it was able to achieve this through something it calls time-reversal processing. As the ultrasound waves enter through the back of the hand they begin as broad pulses that actually become more targeted as they move through to the other side, landing at a specific point on the palm. The researchers liken it to water ripples working in reverse.
"Wearables are already big business and will only get bigger," says Professor Sriram Subramanian, who led the research. "But as we wear technology more, it gets smaller and we look at it less, and therefore multisensory capabilities become much more important. If you imagine you are on your bike and want to change the volume control on your smartwatch, the interaction space on the watch is very small. So companies are looking at how to extend this space to the hand of the user. What we offer people is the ability to feel their actions when they are interacting with the hand."
