The glasses will be the most useful when travelers are navigating a foreign country or trying to read text in a foreign language. Examples given in a statement provided to AFP include reading restaurant menus, although the ability to read foreign-language street signs may prove quite valuable as well. The report also mentions that "the glasses are likely to be ready for visitors attending the 2020 Tokyo Olympics," which explains why NTT Docomo developed the technology to begin with. Such a massive, international event is a great opportunity to introduce a product that bridges the langauge gap. It's similar to Twitter's presence at the 2007 South by Southwest conference, where the company mounted massive televisions that streamed attendees' Tweets and allowed them to communicate en masse."
