A French researcher has built a device allowing disabled people to write or draw on a computer screen using only their eyes, a report said Thursday.
With head-mounted cameras monitoring their eye movements, test subjects were able to write and draw on a blank computer screen in the latest breakthrough for people trapped in immobility by disease or accident.
"For persons deprived of limb movement, this offers a fast, creative and personal means of linguistic and emotional expression," said the report by Jean Lorenceau of France's CNRS research institute.
Lorenceau's system, still just a prototype, compensates for saccadic, or jumpy, eye movements to allow a smooth writing style.
After four half-hour training sessions, his subjects were able to write at a rate of about 25 letters per minute.
Similar systems exist, but none that allow a person to trace their own letters with this level of precision.
In July, engineers said they had built a device using mass-produced video gaming equipment that lets disabled people control a computer cursor with just their eyes -- with a price tag of under $30 (25 euros).
Other technologies require electrode implants in the brain, an expensive procedure.
Such technology offers hope for restoring some level of independence to people suffering from multiple sclerosis, Parkinson's disease, muscular dystrophy and spinal cord injuries or amputees.
In the EU alone, there were more than 16 million people with disabilities who would benefit from such a system, an earlier study had found.
Blamed on the uncontrolled and overuse of farm chemicals, the level of contamination has raised a number of health concerns, with certain villages already showing higher rates of cancer than the national average.
The deputy minister called on South Sudanese farmers in states that have not been hit by famine to cultivate their farmlands to avoid exacerbating the crisis in the country.
Researchers determined that while the Guinean form of the Ebola virus (EBOV) showed a 97 percent similarity to the Zaire strain, the disease was not introduced from Central Africa.
The Ministry of Environmental Protection found that 82.8 percent of the contaminated samples contained toxic inorganic pollutants, including cadmium, mercury, arsenic, chromium and lead.

More compact city designs that cut commutes, insulation to save energy, better public transport, cycle lanes and pedestrian areas can all cut emissions, mainly from fossil fuels.
