Travel companion in Tokyo

Travelers landing in Tokyo’s Narita Airport – which has the ambition to be the most technologically advanced in the world – can rent PDA translators. The e-Navi is able to listen to your voice and translate your sentences with the help of 50,000 Japanese words and 25,000 English (including slang) in a matter of seconds. Besides, e-Navi can be used as as a mobile phone, offers airport information guide and unlimited web browsing.
NEC first developed the technology on Papero (couldn’t resist inserting a picture of it), a robotic voice translating dog before adapting it to handhelds.
