To eliminate the unpleasant feeling of waking up in the morning, French company Withings introduced a biosensor watch that senses the best time to wake the user.

According to Engadget, the Aura watch is equipped with a sensor placed under the bed sheet, connected to the iPhone and can measure body movement, respiratory activity and heart rate.

The sensor is connected to the color changing night light and wake up speaker.

Based on body movements and the light emitted from the night light, which changes from red to yellow, white and blue, the device can determine when to wake up.

Meanwhile, the light changes color according to the user's state, such as blue for waking up, and red for lulling to sleep.

Coupled with an iPhone app, the device can interpret the user's sleeping habits, as well as record room temperature and sounds made while sleeping.
