Excerpt:

A woman paralyzed from the neck down is now able to use a robot arm to give high fives and help her eat chocolate, representing what may be the most advanced mind-controlled prosthetic hand developed for humans yet, researchers said. Although scientists had worked on robotic limbs that monkeys could move with their minds, these new results mark the first time a person could steer thought-controlled prosthetics better than monkeys have, investigators added. "This is a spectacular leap toward greater function and independence for people who are unable to move their own arms," said researcher Andrew Schwartz at the University of Pittsburgh. "This technology, which interprets brain signals to guide a robot arm, has enormous potential that we are continuing to explore.""As we move forward, we might find this is applicable to other types of traumatic brain injury," researcher Elizabeth Tyler-Kabara at the University of Pittsburgh told LiveScience.

Key:

  • Aggregate Sentiment is meant to be an indicator of an individual's overall sentiment.
  • The Mean is meant to be an indicator of an individual's average comment sentiment.
  • The Standard Deviation, when there are enough quotes, will indicate an individual's consistency of sentiment (i.e. a Standard Deviation of 0 would mean they were very consistent in their sentiment and 1 would mean they were very inconsistent).

Note that quote stats are likely to be meaningless beyond the aggregate score due to the tiny sample size. However, they are always provided just in case you find something useful there.
