Joseph Balboni loves sports. An avid tennis player and golfer, as well as baseball fan, the 46-year-old insurance agent became increasingly frustrated over time as his eyesight dimmed due to keratoconus, a degenerative eye disorder. Unable to return the tennis ball or see the pitch at Red Sox games, he faced the prospect of a corneal transplant to restore his vision and eye comfort.

As fantastic as computers are at processing mountains of data at lightning speed, they still can't beat the human brain at, for instance, detecting a friend's face in a crowded airport terminal, or even at more specialized tasks such as detecting suspicious objects in X-ray scans of checked baggage. The human brain can do these tasks not just very well but also very rapidly, within a fraction of a second, says Georgetown University Medical Center neuroscientist Maximilian Riesenhuber, Ph.D., of the Laboratory for Computational Cognitive Neuroscience. However, while the brain's visual system can perform the actual detection task very rapidly, even for multiple images presented at the same time, turning these decisions into behavioral responses is much slower.

 | Movie characters from the Terminator to the Bionic Woman use bionic eyes to zoom in on far-off scenes, have useful facts pop into their field of view, or create virtual crosshairs. Off the screen, virtual displays have been proposed for more practical purposes -- visual aids to help vision-impaired people, holographic driving control panels and even as a way to surf the Web on the go. ...> Full Article |
