Almost at the end of the year Quest Visual- a software starter excited iPhone users by launching a magical translator app called the “Word lens“. It’s an instant translator that uses the video camera of your iPhone to translate words from one language to another. The founders of Quest visual Otavio Good and John Deweese have spent almost two and half years in creating this magic app.Source : http://www.businessinsider.com/how-to-use-word-lens-2010-12
Flying to a foreign land where the locals do not use the language that you know in their sign boards, menus, caution boards, etc, would definitely be a serious trouble. That wouldn’t be the case anymore, if you have word lens installed into your iPhone. Initiate the app and show the video camera of your phone in front of the board, you would see the words translated in English.
The Word Lens app hit the Apple App Store last week to a lot of hype.There's a justification for the hype: Word Lens uses character recognition to instantly translate text it sees.The words appear on your phone's screen in the same font and style as the original in front of you, so it looks like someone swooped in and replaced the sign you were just looking at.A very neat trick if it works as advertised.But in our preliminary test, the results were nowhere near as silky smooth as the company shows in its promo video. It's good at translating the letters, but the results are choppy.
We downloaded a few Spanish signs from Google Images to see what Word Lens could do. Here's what we saw:
You have to hold your phone incredibly still. If you move, the text will revert to the original language while the software attempts to translate it again.
Overall, the translation is just so-so. The grammar and syntax isn't perfect, but it's good enough to get the gist of what each sign is saying. We expect it to only get better as more updates and dictionaries are released.
Word Lens has trouble with lots of text and there's a limit to the amount it can translate. For long signs, it automatically crops the section it is working on, so you have to read it piece by piece.
Word Lens will work well enough if you need to read a street sign or specials in a restaurant. It's a great app if you're doing business in a new country for the first time and need some extra help getting around. There are only two dictionaries available right now, Spanish to English and English to Spanish. (And it's only $4.99 per language, so it's a small investment).
