This “Noriko-San” sleep mask was developed for “drowsy train commuters” afraid of sleeping past their stop and consists of a scrolling LED display that communicates the wearer’s destination to other passengers in the train. Of course, this relies on other people actually caring enough to wake you up in time, which its developer, Pyocotan, found not to be the case when other passengers felt more uncomfortable with the mask than helpful. Not to be outdone, he believes that if the mask is widespread enough, that it may eventually gain more acceptance from people. The cost of the mask was around $200 USD to develop so it would probably have to come down in price as well.
