Word Lens is an eye-catching iOS app for the iPhone and iPod touch. It is based on an augmented reality technology and offers real time translation of text. The only thing you need to do is just to point your device's video camera at a sign and the program translates and superimposes the translated text onto the video in real time. Now available only language packs for Spanish to English and English to Spanish for $4.99 each. More language packs are in the works. Text is translated on a word-by-word basis, so context is not taken into account.
