Kinesis cured my sore hands (RSI)
2007 Kinesis USB DEFECT on Mac
I purchased a third Kinesis keyboard since I
replaced my Linux PC by a Mac and an adapter was required.
Perhaps I could have found an adapter but I liked the idea of a new USB
keyboard with two USB jacks.
On installation, I realized the USB jacks are about worthless.
On my new Intel iMac I cannot have
anything plugged into the keyboard USB port during boot up
or the keyboard will not be found.
The USB ports are usable after boot up, but that does not make them acceptable.
Who'd want a computer that works but freezes on restart?
I consider the USB ports on my Kinesis keyboard to be worthless on my Mac.
I'll notify Kinesis and see what they say. [July 21, 2007]
I am not the first to
report this bug.
It might be an Apple bug.
Somebody please let me know if this bug ever gets fixed. I am claerbout _AT_ stanford _DOT_ edu
 This is how I developed sore hands and wrists (RSI)
and how I got cured. I don't say it will work for you.
I bought a special keyboard made by Kinesis company (phone 425-402-8100).
Their web site is
I bought the
original keyboard they now call "contoured".
Actually, I bought two, one for work and one for home.
They cost me about $500 each. (prices lower now)
Below are my experiences
written mostly in late 1994 and early 1995.
(Still happy with Kinesis in 2005.
I threw away the Sun adaptor and now use the keyboards on
PC (Linux) and Mac. 1997 prices about $250.)
After 40 days of Kinesis keyboard use
My hands no longer suffer. I am satisfied with this purchase.
Now however, whenever I must use a regular keyboard
I type at about 80% normal speed.
Mac and Sun keyboards delivered 3 weeks apart.
My two keyboards map the keys differently!
- Mac installation was a few minutes. (Oct 5)
- Sun installation was a few minutes. (Oct 7)
Later I read the manual and learned how to remap keys to my heart's delight.
Douglas Alan = nessus _AT_ space.mit.edu made the good suggestion
for vi users of swapping the escape key and the "end" key.
MacX: use the Ctrl key on the RIGHT hand.
SunX: use the Ctrl key on the LEFT hand.
I am pleased that Kinesis gives a small tool to remove the caps lock key.
After a few disoriented hours, I found I could do useful work
at about 75% of normal speed and I sped up steadily.
Day of ordering keyboards (Aug 14, 1994)
I order two Kinesis keyboards, one for my Macintosh and one for my Sun.
They cost $490 each (including Sun and Mac adapters).
My expectations are:
that the keyboards will install quickly and function properly
that my wrists will be less sore.
that I will become a better touch typist by having identical keyboards.
Escape key does not look convenient for vi users.
(Later I learned to remap keys.)
Hand health history
I am 56 years old (in 1994), on and off a keyboard all day and all evening.
I have used ergonomic typing table and chair for many years.
About three years ago I had a minor bicycle accident
that bent my right pinky. About a year later
I began having wrist pains, particularly in my right wrist.
I found I could alleviate pain somewhat by two methods:
About 15 years ago I wrote a book with a sharp pencil.
I developed RSI in my pencil fingers.
I ``treated'' it by winding a big knob of adhesive tape
around the mechanical pencil making it softer to grasp.
When I switched to typing, the pencil RSI went away.
I believe switching back to a pencil would bring back
the pencil RSI almost immediately.

sports wrist brace
I notice that keys occasionally stick on one of my keyboards.
It is not physically connected to any particular key;
it is electronic; the "key up" pulse is not recognized
and the key goes into autorepeat mode until I hit another key.
Kinesis freely swapped a converter box, but that didn't fix it.
When I swapped my Sun and Mac keyboards, the flakey keyboard swapped position.
Then Kinesis offered to swap the flakey keyboard.
Since it happens only once or twice a day
I decided not to bother with a replacement keyboard,
and the problem has not gotten any worse 11 years later.
Douglas Alan firstname.lastname@example.org says he has the same problem
and Kinesis said to him and me that nobody else noticed such a problem.
lindstro@BIOSTAT.WISC.EDU also has the same problem.
