What we've got here is a what we call the interactive throwing sleeve. It's got a sensor on my wrist
to measure that motion and one on my elbow to measure that motion. So we can use this for things like throwing
to look at technique. So not only can we look at technique, we can start to put sounds on that technique
to reinforce aspects of technique and then we can use that in studies or to train people
where you go in and you rapidly do repeat throws. And it makes it more challenging by having to say get the ball in the ring
and make the noises. So on the computer screen here we can start a throw. Right and so in three seconds
did I get the ball in or not? So let's say I miss completely and then we go again.
Okay, so let's say I got that one in or give me a five for that one. So that's basically what we do.
So we've been studying that with the top end netballers in Australia and we've looked at their technique
and we've tried to take the key aspects of that and to bring it back for kids in school.
So we've taken this into the schools and about 20 kids we were looking at can they learn that across the course of a week.
So basically this person can come and show them, they're left with the sounds of that and they can move on
and show the next person so they can have a more meaningful training session.
And we've shown that that actually builds more robust technique and helps them to learn faster.
So basically we're stretching it and that's what we're sensing. So when I flex like that this stretches
and there's a little filament in there that moves and it measures how long a piece of string is basically,
literally and this little electronics unit here measures that string length because it changes its resistance.
So then we beam that into the computer, it makes the red and white graphs on screen
and that in turn triggers the sounds to play. So we can choose whatever sounds we like.
In this case we've used a beat so the object is to try and complete that drum beat.
The original air guitar which has sent to this elbow, sent to this elbow running through the shirt,
a little transmitter going into the computer to control sounds and we'll make one go.
We've got the throwing sleeve from that where we take that sensor, stick it on the wrist and we move this to there.
And then that would be our throwing sleeve which we've done a lot of work with Netball and some of our athletics people
that went to the Olympics and all that was about technique and using sound like what you just heard
to give them some feedback on their performance, was it good or bad.
Sometimes we ask them to make the sound, sometimes we tell them not to make the sound
so their job is just to do their sport and subtly change what they do.
But when we take it into kids, so we'll sit them down and we'll be trying to get them to do a specific technique
and we'll make the sound go boom there and there.
So if they get the boom, they've done the sound part right
but they've still got to get the ball through the hoop.
So at that point they've got to do both which makes it much harder task
and it encourages them to explore their technique more.
So if we want to do it in swimming, we need a waterproof one of those
and some guys up at Griffith Uni have done that and we need a waterproof one of these.
So I've played around with making one out of wetsuit so that you can fully encapsulate it.
So in swimming it's all about protecting it from chlorine.
I did chemical engineering at uni which is kind of a bit of cooking and a bit of plumbing
and a little bit of analysing things.
So I went into paper making and then I went into packaging and putting electronics into packaging
and then I wanted to, I saw some work that was done like this
and I wanted to be part of that so I was able to join that team
and from there I've been able to create these new technologies
and I'm interested in music so it was pretty obvious we use that sense
that we start controlling things in music.
So we're now going the other way instead of just using the controllers to control music
we're now using the music to help people learn.
So the music has an important part to play in that.
So when you hear sounds they will affect different parts of your brain in different ways
so we're trying to understand that and use that to advance human performance.
Where to from here, well I'm interested in innovation
I want to see some of this stuff become more available
so that's about understanding value and understanding supply
and putting that together in meaningful ways so we're doing that.
What we've got here is effectively one of these which is a WAWA pedal
plugs into the back of your effects unit, controls and effects
so in this case I've chosen the WAWA
and we're using my elbow to essentially do that pedal motion
so like your foot going like that, my arm going like that
so we're going to use jester to control the guitar effect.
