Welcome to Human Computer Integration Lab at University of Chicago. I’m Yudai Tanaka,
and I’m gonna present you electrical head actuation,
a novel interface concept where interactive systems directly manipulate the user’s head orientation.
I’m gonna show you what I’m talking about.
Here is my colleague, Shan-yuan, who is equipped with our system and he is gonna close his eyes
He has no idea what’s going on.
And I will control his head orientation to this way.
So, what just happened is that Shan-yuan is wearing these electrodes on the front side of the neck and the back side of the neck.
So, what’s gonna happen when the system sends the signal is that these electrodes will send the electrical pulses to Shan-yuan’s neck, neck muscles.
And upon receiving these signals, his muscles will contract, that will cause involuntarily muscle actuation.
That’s how his head orientation was moving around last time.
Now, I will introduce an interactive application that makes use of our technique.
Shan-yuan, wear this Hololens.
This display shows what Shan-yuan is looking at.
Hey Shan-yuan. Hi.
Alright, Shan-yuan, this is a fire safety training, so there is a fire somewhere in this room and you have to put out the fire.
Fire in this room? Yeah.
Oh, the fire is there! What should I do?
Find the fire extinguisher and use it to put out the fire.
Find the fire extinguisher? Hmm... I don't see it.
woo, oh, ahh! It’s here!
Good job, Shan-yuan!
That was really fun.
Ok, now you can put off the head set.
So what just happened is our head actuation system directly moved Shan-yuan’s head orientation
to change his point of view to help him with finding the fire extinguisher by making him directly look at it.
Now I'm gonna show you a different example
where our system will render the force feedback in a virtual reality experience.
Now Shan-yuan, have a seat.
This is a roller-coaster VR application and his head will be actuated to the up/down according to the movement of the roller coaster.
That's really exciting.
That was it for electrical head actuation,
a new concept that allows interactive systems to directly manipulate the user’s head orientation.
Thank you bye bye.
