Imagine sitting in a café on holiday enjoying a bottle of wine. You would like to know more about it, perhaps order some for home. You get out your smartphone, take a picture of the label and are instantly taken to a website with information about the vineyard and the grape variety, as well as a link to an e-commerce site where you can order a case at the click of a button. You wonder what the historic building on the piazza in front of you is, so you hold up the phone, which links to a Wikipedia page on the history of the monument. You then turn your attention to the menu, written in a language you do not speak. Hold the smartphone over the page and the text is translated for you.
想象一下，假日中的你正坐在咖啡馆里，享用着一瓶葡萄酒。你还想进一步了解它，或许还想再点一些带回家。于是你拿出智能手机，拍下酒的标签，便立即进入一家网站，上面显示出葡萄园和葡萄品种的信息，还有一个电子商务网址链接，只要点一下按钮，就可以订购一箱。你想了解一下面前广场上那幢历史建筑，于是举起手机，上面出现有关这幢建筑历史的Wikipedia页面链接。然后你的注意力转到菜单上，上面的文字是你看不懂的语言。将智能手机停留在菜单页面上，文字就为你翻译出来了。
