If you have problems to understand the language in a foreign country when you're traveling, then this conceptual gadget called "ViewTrans" is the solutions. Digital translators may not be new to the scene, but what makes ViewTrans different is that it "translates what you see". ViewTrans changes the foreign script that it views to your language of choice and displays it on the screen. I think it is a good idea and nice concept.
