As quoted from Daily Mail, on Tuesday, December 24, 2013, Vigo able to tell when the user gets tired. This gadget is claimed as a device that can be used to measure alertness by way of sending a warning in the form of vibration to make someone awake, or give them advice to rest.
Vigo is powered by a rechargeable lithium-polymer battery, which the company says lasts two to three days, depending on use. (Picture from: http://www.gizmag.com/)
According to the Vigo creator, this personal device will track the movement of the body and also the pattern of the wearer blinks to later remind the wearer of when they are must rest.

Weighing 20 g (0.7 oz), Vigo is equipped with an ARM Cortex-M0 16MHz processor, low-energy Bluetooth 4.0, infrared sensor, accelerometer, gyroscope, vibration motor, and is reported to last 2-3 days on a single charge.  The Vigo team, made of University of Pennsylvania graduates, has currently launched the project on Kickstarter, and the Vigo can be backed for $79 (retail $119).  Expected shipping date is May 2014.
When Vigo detects sleepiness, the device "nudges" the user, alerting them to their drowsy state and prompting them to re-focus. (Picture from: http://www.gizmag.com/)
"The idea is simple, even though your brain has a tendency to trick you into thinking hard day-by-day, but your body can not hide it when you are tired," said the Vigo creator, from the University of Pennsylvania. "With infrared sensor, accelerometer, and algorithm, Vigo know when you are sleepy," he concluded.

Fatigue detection device is shaped like a Google Glass in one hand, and can be worn while driving a car or working at the computer. This tool will work like a mother who tells users to sleep when it is too long to work. *** [EKA | FROM PREVIOUS SOURCES | DAILY MAIL | MEDGADGET | GIZMAG]
