I would not usually post the
personal experience of a student I have worked with. But this blew me
away. The student sent me an unsolicited
summary of his experience. All I did was
to MEASURE the computer screen
conditions needed to maximise his reading off a computer screen.
This was quite complex, not a
question of ‘what do you like?’ or which do you prefer. It is a rigorous
protocol. The last two posts have had
the details/ metrics of the response of his visual system to the use of the identified settings.
Now this guy had been identified
as dyslexic, with the implication that he had
- a working memory problem
- A phonological processing problem
In any system, you need to
identify if something is ‘a limiting factor’. If it is then changing it will
increase or decrease performance. Changing anything else will either make it
limiting, do reduce performance or have no effect..
The evidence is amassing that
for many people the Visual attention span can be the limiting factor on reading
performance for many dyslexic people and many people not diagnosed as dyslexic.
For this sort of outcome the
screen optimisation must have increased the visual attention span of the person.
The next step is to undertake an academic
study to find out of this is so! Watch
this space.
James has given me permission
to quote him.
Enjoy the read.

HI Peter
Yesterday was fantastic, as soon as I got home I started modifying all my computers and equipment to use the new colours we found work best.
I also setup a program called F.Lux which is a program that changes the "colour temperature" of your screen based on the time of day.
Basically it reduces the brightness and I think saturation, which makes it far easier to continue working when in low light conditions and when tired.
If you're interested here is the link for f.lux:

When I combined both the RGB colour change and the screen "colour temperature" changes from f.lux i was able to work for 11 hours revising for my exam today.
I took breaks every 20 mins from reading, but I was able to recall information far easier, and unlike previously, none of the concepts in the material seemed beyond my comprehension.
I went into the exam today and answered 48/50 questions, and I didn’t even need the extra time allocated to me.
I think it’s safe to say the changes I made based upon the session we had work fantastically well, far better than I anticipated.

You can quote me, and the psychological consequences were
evident before my exam. I was revising with friends taking it in turn to ask
each other questions, and they were far more worried than I was, for once they
were asking me the answer to things, when normally it is the other way round.
It’s going to take me a long time to go over things from last term using the new colours, but I think I can learn the things I didn't and use that to catch up.
