I learned to type and I'm a pianist.   My mother was a typing teacher.    I
can't imagine people not typing with their whole hands.  But as a result of
one finger typers they make these cheap assed keyboards that destroy the
fingers of people who really type.      If everyone was competent, 100
hundred words a minute or more,  they would demand a better product but it
doesn't matter with the one finger typists.     In fact they would do better
with a claw.   Maybe that is how birds evolved.      My Logitec keyboard
began to destroy my hands and elbow a year ago.   First thing to go was my
synovial sacks on my little fingers.    I paid for a Steinway to protect my
investment in my hands but this Logitec ate them.     So I went to the
hospital and found that the rehabilitative answer was to redo my childhood
piano exercises with the wrist.    Leopold Godowsky weight and balance
exercises.    I showed them to my rehab therapist and he said:  "sure, those
are the ones we use for Carpal Tunnel Syndrome."      

 

What would really be helpful would be if I had my old Royal typewriter with
the balanced key strokes.    My mother typed into her eighties on that with
no trouble at all.   Meanwhile the Japanese are developing tools that
separate people from their awareness and remove the connection between the
brain/nervous system/ and the hands.   Sounds dumb to me.    It's not the
result, it's how you get to the correct result that allows from predictable
generic technique.      Most technology is just a substitute for a slave to
do your work while you daydream or chat.

Video: Hand-hacking helps budding musicians

WANT to learn a musical instrument, but can't find the time to practise? A
device now under development can take control of your hand and teach you how
to play a tune. No spirits of dead musicians are involved.

PossessedHand <http://lab.rekimoto.org/projects/possessedhand/> , being
developed jointly by the University of Tokyo, Japan, and Sony Computer
Science Laboratories, also in Tokyo, electrically stimulates the muscles in
the forearm that move your fingers. A belt worn around that part of the
subject's arm contains 28 electrode pads, which flex the joints between the
three bones of each finger and the two bones of the thumb, and provide two
wrist movements. Users were able to sense the movement of their hands that
this produced, even with their eyes closed. "The user's fingers are
controlled without the user's mind," explains Emi Tamaki
<http://lab.rekimoto.org/projects/possessedhand/>  of the University of
Tokyo, who led the research.

Devices that stimulate people's fingers have been made before, but they used
electrodes embedded in the skin, which are invasive, or glove-like devices
that make it hard to manipulate an object. Tamaki claims that her device is
far more comfortable. "The electric stimulations are similar to
low-frequency massage stimulations that are commonly used," she says.

Having successfully hijacked a hand, the researchers tried to teach it how
to play the koto
<http://en.wikipedia.org/wiki/Koto_%28musical_instrument%29> , a traditional
Japanese stringed instrument. Koto players wear different picks on three
fingers, but pluck the strings with all five fingertips, so each finger
produces a distinctive sound. A koto score tells players which fingers
should be moved and when, and from this Tamaki and her team were able to
generate instructions telling their device how and when to stimulate the
wearer's muscles.

PossessedHand does not generate enough force to pluck the koto strings, but
it could help novice players by teaching them the correct finger movements.
Tamaki and her team found that two beginner players made a total of four
timing errors when using PossessedHand, compared with 13 when playing
unassisted. After prompting from the device, the players also made one less
mistake about which finger to use.

Perhaps not surprisingly, the players found it unsettling to have the device
move their hand by itself. "I felt like my body was hacked," said one.
Tamaki is confident that people will get used to the idea once they see how
useful it can be: "We believe convenient technology will overcome a feeling
of fear."

As well as helping would-be musicians, PossessedHand could be used to
rehabilitate people who have suffered a stroke or other injury that impairs
muscle control. Therapists already use electrical muscle stimulation to help
these people, but existing non-invasive devices can only achieve crude
movements such as contracting the entire arm.

Henrik Gollee <http://www.mech.gla.ac.uk/%7Ehenrik/> , who researches
rehabilitation devices at the University of Glasgow, UK, says PossessedHand
could help patients train a wider range of movements. "I was surprised by
the level of fine movement they can actually achieve," he says.

Simon Holland <http://mcl.open.ac.uk/sh/> , director of the Music Computing
Lab at the Open University in Milton Keynes, UK, points out that there is a
big difference between learning to play one song and being a competent
musician. "You might learn a fingering and be able to reproduce that
performance, without necessarily being able to perform simple variants," he
says.
