Two years ago an accident left Justin Cochran paralyzed from the neck down, but he doesn't let his wheelchair get in the way of much.
"I know what I want to do and how I want to live my life, and I'm not going to let something like a spinal cord injury stop that," Cochran told Ivanhoe.
Cochran counts on sip-and-puff systems to help him control his environment; but soon, this tiny magnet could give him more possibilities. It allows people to control wheelchairs and countless other devices by moving their tongues.
"It lets them use their tongue motion and translate it to different commands," Maysam Ghovanloo, Ph.D., assistant professor of electrical and computer engineering at the Georgia Institute of Technology in Atlanta, Ga., told Ivanhoe.
Electrical and computer engineers at the Georgia Institute of Technology developed the system. Equipped with a magnetic sensor, the tongue acts like a joystick. A special headset tracks every move, whether the tongue moves from its resting position or it touches a certain tooth. In less than a second, each movement is translated into a command to control a wheelchair, a computer cursor or other device.
"Theoretically, there are an unlimited number of commands that the user can define in order to control their environment," Dr. Ghovanloo said.
The next step is letting people with disabilities test the system themselves. Cochran says he's ready to be the first.
"Yeah, I can't wait to try it," Cochran said.

With gas prices spiking over $4 this year, Americans are spending more than ever to fill up the tank. Truckers alone have seen the cost of a fill-up jump 116 percent in the last five years. That can add up to higher costs for anything that gets to you in an 18-wheeler, from food to furniture. Thanks to recent research, science may have found the answer to the problem.
The next time someone installs tires on your vehicle, watch closely. The method they choose could steer you into a dangerous situation. Researchers have found three out of four people don't know where two new tires should be placed on a vehicle. It's a question of safety that even sparks debate among tire experts.
The odds are five-to-one you've been involved in an office pool; but are those bets really enhancing your enjoyment of the actual event? The answer may surprise you.
Thousands of people in Texas are still cleaning up after Hurricane Ike's devastation. One of the toughest tasks for relief agencies after a disaster is assessing where and how many people need help. Scientists have developed a new, low-cost imaging system that could make a lifesaving difference.
Every year, Americans spend more than $38 billion on their lawns and gardens. No matter what you're growing, a sudden frost or freeze can spell serious trouble. Soon, science could come to the rescue with antifreeze for plants.
Coughs are one of the most common reasons patients see a doctor. For patients with chronic ones, diagnosis and treatment can be frustrating; but new, simple test could help millions crack the mystery of their persistent problem.
Three out of four children fall victim to an ear infection by the time they're three years old, many of them during winter when viruses abound. Treating the common problem can be a tedious procedure, but a new device makes healing ears simple.

Sodas, candy and processed foods are packed with tooth-decaying, cavity-causing sugar. For the past 40 years, experts have seen a decrease in the amount of tooth decay in children; but according to Centers for Disease Control statistics, the trend is reversing. To tackle the problem, one dental scientist has found a way to use candy to help prevent cavities.
Alcoholism affects over 17 million people. Without proper treatment, it's a devastating disease that can ruin lives and relationships. A new therapy that comes in a pill is bringing new hope to alcoholics.
Gamers spend hours playing their favorite video games. With all the hi-tech graphics, most are designed for those who can see. A new game created by electrical and computer engineers is scoring high marks for visually impaired players, too.
