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館里，享用著一瓶葡萄酒。你還想進一步了解它，或許還想再點一些帶回家。于是你拿出智能手機，拍下酒的標簽，便立即進入一家網站，上面顯示出葡萄園和葡萄品種的信息，還有一個電子商務網址鏈接，只要點一下按鈕，就可以訂購一箱。你想了解一下面前廣場上那幢歷史建筑，于是舉起手機，上面出現有關這幢建筑歷史的Wikipedia頁面鏈接。然后你的注意力轉到菜單上，上面的文字是你看不懂的語言。將智能手機停留在菜單頁面上，文字就為你翻譯出來了。
