Vigo can be potentially life-saving for drivers and people in other situations where losing alertness can be dangerous, especially since your brain can get fatigued before your body starts to feel tired. The device is currently on Kickstarter and has already reached more than $38,000 of its $50,000 goal, and with 15 days left to go, it has a decent chance of getting funded. The device’s early bird price is a very reasonable $59.
