Can anyone of you guess what is this? Its a Nap Alarm, a wearable low-cost gadget that keeps you awake.The Nap Alarm is placed behind your ear. If you fall asleep it vibrates. The small gadgets determines based on your head movement speed if you actually are about to fall asleep. Pretty nifty – still I recommend stopping to drive and making a break when you start falling asleep and i think i should get one for myself as well. Do you know how it feel when something just vibrate off your ear? Haha.. Only cost around $12.

Update: My friend just inform me about this piece of gadget. He said he dont think this is suitable for girls. The vibration going to trigger the alarm for sensitive girls. *gasp*
