A researcher at Osaka University's Graduate School of Engineering Science has developed a system enabling users to control an Apple iPod by blinking.

According to Kazuhiro Taniguchi, who developed the system, users must close both eyes for one second to start or stop the system. Winking with the right eye will skip forward a track or to skip backwards simply wink with your left eye.

The system uses the Kome Kami Switch, which translates to Temple Switch that comprises a single chip computer and two infrared sensors and is so small it will fit into a pair of spectacles.

"This system doesn't malfunction even if the user eats, talks, walks and runs. Normally you blink in an energy-saving manner, very quickly and lightly, but you would close your eyes more firmly to operate a device," Taniguchi told Reuters.

Taniguchi expects the system to be used as a hands-free control for medical personnel, rock climbers and motorcyclists. He is also working on a system that is controlled by teeth clenching.
