Otavio Good has created an iPhone app that can capture a picture of a street sign and translate it. Although the app is only currently available to translate between english and spanish, Quest Visual, run by Good, says there are plans to add other languages as well.   This app can be very helpful for travelers in need of identifying things such as stores, restaurants, and can even be used to figure out directions. Meant mainly for street signs in a different language, the app can quickly show desired results because it is done in real time. The app is currently only available for iPhones, but they are already in the works of making an Android version.
