Going overseas to a foreign country and you are not very familiar with the language there? why not try out this iPhone app called word lens.
As demonstrated in the video below, by simply pointing your iPhone at the foreign words, the app would be able to instantaneously translate them into English , and best of all you would not require internet access to utilize this app.
The application is available for free at the apple app store, but you would need to do an in app purchase of US$4.99 for each of the language pairs, currently there are only 2 language pairs available; the “English to Spanish” and the “Spanish to English” translations.
If your destination is Spain or any other Spanish speaking countries, this is one app you should try out.
