Georgia Tech researchers develop way for wheelchair users to steer with head tilts, facial expressions
Georgia Tech researchers testing expertise for energy wheelchair customers involving head tilts and facial expressions
Two Georgia Tech engineers, Nordine Sebkhi and Arpan Bhavsar, say that they’re able to ask for volunteers and take a look at out a brand new type of expertise for energy wheelchair customers. The 2 engineers say that the expertise will use magnetic sensors to permit the person to maneuver round utilizing head tilts and facial expressions.
ATLANTA – Contained in the Conscious Home on the Georgia Tech campus in Atlanta, Matt McCoy is testing out what might be the following large factor in assistive expertise: a system of magnetic sensors on his face and behind his ear permitting him steer his energy wheelchair by tilting his head.
For 5 years, Georgia Tech postdoctoral analysis engineers Nordine Sebkhi and Arpan Bhavsar have been fine-tuning the expertise they name MagTrack, preparing for McCoy and a deal with of different volunteers dwelling with a incapacity to try it out.
“I would say we really feel fairly nice, yeah, after the testing that we noticed,” Sebkhi and Bhavsar say. “We’re capable of navigate the hallways and go contained in the bed room with out destroying the house.”

McCoy didn’t need to do an interview, however he was comfy being videotaped as he was maneuvering his chair across the dwelling, sporting magnetic sensors that detect when he tilts his head or modifications his facial features.
Sebkhi and Bhavsar say their hope is their MagTrack expertise can provide individuals unable to maneuver from the neck down extra independence and be much less cumbersome than the at the moment out there assistive expertise.

“So, the thought is how can we create one thing that’s wearable, that shall be on them on a regular basis, is not going to muddle something round them, and can allow them to be capable to eat, drink, with out having to reset that expertise?” Sebkhi says.
And, MagTrack does greater than drive a wheelchair.
Customers can make use of it to open up and management smartphone apps or function good expertise of their houses with a head tilt or facial motion.
“At any time when the person makes a cheek twitch, or eyebrow elevate, the sensor will decide that up, after which it can switch that to no matter command you might have mapped it to,” Bhavsar says. “So, for instance, on the wheelchair, one of many cheeks can act to cease the wheelchair. On the cellphone, for instance, one of many cheeks can act as a left click on.”
Bhavsar and Sebkhi are working with a crew from Brooks Rehabilitation, and so they plan to spend the following yr having volunteers from Shepherd Middle and different rehabilitation hospitals check out the MagTrack assistive expertise and supply their suggestions.
They’re nonetheless figuring out some kinks and making an attempt to reply some greater questions, resembling whether or not there’s a position for this newer expertise.
Principally, they need to hear what energy wheelchair customers consider the MagTrack methods and the thought of sporting wires on their faces.
“One of many large issues with this inhabitants is that they do not need to draw consideration to themselves,” Sebkhi says. “So, they need an assisted expertise that’s as inconspicuous as attainable. That is what the problem is. How will you make one thing that may be very sensible, like a common controller, just like the one we now have, however it’s inconspicuous? That is the true problem. So, we now have to see, the place is the road? Is having wires in your face okay for you?”
