Google acquired Quest Visual on in order to incorporate Word Lens into its Google Translate service. According to the January 2014 New York Times article, Word Lens was free for Google Glass. At Google's unveiling of its Glass Development Kit in November 2013, translation capabilities of Word Lens were also demonstrated on Google Glass. On Google Play, there were both the free demo and the full translation-enabled versions of the application. The application was free on Apple's iTunes, but an in-app purchase was necessary to enable translation capabilities. Until early 2015, the application was available for the Apple's iPhone, iPod, and iPad, as well as for a selection of Android smartphones. For example, using the viewfinder of a camera to show a shop sign on a smartphone's display would result in a real-time image of the shop sign being displayed, but the words shown on the sign would be the translated words instead of the original foreign words. The words were displayed in the original context on the original background, and the translation was performed in real-time without a connection to the internet. Word Lens used the built-in cameras on smartphones and similar devices to quickly scan and identify foreign text (such as that found in a sign or a menu), and then translated and displayed the words in another language on the device's display.
