My name is Dr Darren Kelly.

I am a scientist (physicist/mathematician/computing expert) and inventor.

I am also a musician and performer (singer/keyboardist/percussionist/electro/dancer) a.k.a. "PLAY".

I am also the developer of a gestural music "air instrument" called Drancing:

http://www.webel.com.au/project/drancing

My system uses motion sensors from triaxial accelerometers in a sensor suit
to synthesis light and sound in real-time, and to trigger and modulate samples.
I have been developing it for about a decade,
and there are any number of similar gestural instruments,
all of which have long been able to act as "air guitars",
and nearly all of them superior in application
of motions transducers and audio nsignal processing to Dr Helmer's.

Although the conductive fibre technology he employs
is perhaps novel - or at least nifty - there is in my
considered opinion not one single musical aspect of his
"air guitar" that is novel or even vaguely innovative
(let alone "world first" as some media outlets are claiming).

Indeed, whereas much older instruments like my Drancing system
(and many others before it) use real-time synthesis of sound (and light and visuals)
from motion signals, Dr Helmer can only trigger pre-recorded samples, which is oh-so old hat.

Everybody involved in gestural music can do that,
the discipline is decades old, and so are "air guitars".
They are so old that every year somebody else invents one.

To make it worse, in some presentations he is merely playing back triggered
samples ALONG WITH NON TRIGGERED MUSIC PLAYBACK, which is close to cheating,
and certainly not as convincing as instruments like Drancing which actually
synthesis new sounds from motion signals (as well as triggering and modulating
drum samples or - heaven forbid - pre-recorded guitar samples)

As one online commentator already put it:

"Of course, given that he's playing along with a backing track,
it's quite hard to tell what noises are actually being made by the shirt,
or how the relate to the good doctor's extravagant arm movements…"

Hear hear. Dr Helmer seems to admit elsewhere that
he is not a musician, which does not surprise me much.

I have personally phoned Dr Helmer to tell
him these things, however he unfortunately
does not seem to want to hear the truth of it
(preferring presumably his 15 minutes of fame).

Rather, he keeps insisting in literally hundreds
of online articles, interview, an webcasts,
that he is the inventor of "the first air guitar"
that actually works, which he can only conclude
out of complete ignorance of the work of others decades ago.

Indeed he had not even heard of my own work,
and I am clearly one of Australia's pioneers
of gestural music. And certainly I am one
of the world's leaders in applications of
triaxial accelerometers for the task
(even if not funded so comfortably by the CSIRO).

Dr Helmer had likewise not ever heard of Wayne Siegel's
work at DIEM in Denmark, who already employed bending
sensors and wireless data telemetry just like
Dr Helmer very effectively over one decade ago
for very convincing performances
(which I witnessed on his kind invitation).

And Dr Helmer seems to not know of the dozens of
gestural instruments used by members of the
online Dance-Tech community, many of which
serve as "air guitars".

I congratulate the CSIRO for their innovations
in matters of textiles, however I do wish that
Dr Helmer would tone down his outrageous claims
about being the world's first "air guitar" inventor.

In fact, lots of people were already the world's
first "air guitar" inventor last century, and
nearly all of them used sensors in shirts,
although maybe their wires were thicker than
Dr Helmer's fibres.

The "air guitar" is merely a particular operation
mode of any flexible gestural instrument, and
I suggest that literally hundreds of media students
and musicians have also done similar (without
fancy conductive fibre T-shirts, just good old wire).

What may be a "world first" is the persitent extent
to which Dr Helmer is exploiting the CSIRO's media
leverage and the Australian taxpayers' dollar for
self-promotion without informing himself about prior art.

Dr Helmer seems to have discovered virtual reality.
Wow. Perhaps he should - as scientist - research
non-virtual reality a bit before his next media
release or taxpayer-funded webcast,

Yours Gesturally and Accelerated,

Dr Darren Kelly (developer of Drancing)

Drancing: its just another "air instrument" with
sensors in a shirt that can be used as an "air guitar" !

PS: Since I cannot afford the media coverage
Dr Helmer is enjoying, do please forward this
to anybody you wish, publish it whereever you like,
(at least until Dr Helmer tones it down a bit).
