因为结识了一位失语者朋友，王娜娜萌生了为对方做点什么的念头。于是她和朋友发明了一款能够翻译手语的臂环，希望能够帮助到更多有需要的人。
Wang Nana is a postgraduate student at the School of Computer Science and Engineering, under Beihang University （in Beijing）. Wang and her partners have invented a sign-language-translation system. Wang hopes the system will help ＂language-dysfunction people＂ communicate with people who do not suffer from such dysfunction.
