Japan is already famous for making weird gadgets. And this is no exception. Japanese company, Lofty announced a pillow which can measure the depth and quality of a person’s sleep. It works by keeping a track of head movements with the help of a sensor. The lesser the head movements, more sound sleep you have.
The LCD display at the side compares your sleep with the previous data and suggests you to take some quick naps in office hours ;). It will be releasing in Japan in September for 45,000 Yen (US$392).
