A telephone , or phone , is a telecommunications device that permits two or more users to conduct a conversation when they are not in the same vicinity of each other to be heard directly. A telephone converts sound , typically and most efficiently the human voice , into electronic signals suitable for transmission via cables or other transmission media over long distances, and replays such signals simultaneously in audible form to its user. The word telephone has been adapted into the vocabulary of many languages. It is derived from the Greek : τῆλε , tēle , far and φωνή, phōnē , voice , together meaning distant voice . First patented in 1876 by Alexander Graham Bell and further developed by many others, the telephone was the first device in history that enabled people to talk directly with each other across large distances. Telephones became rapidly indispensable to businesses, government, and households, and are today some of the most widely used small appliances .
A new app just hit the iTunes App Store with the slightly unassuming name "Word Lens." You may think it's got something to do with typography or photography...but you'd only be partly right. It also instantly translates Spanish to English. What the app does is take the image stream from the iPhone's camera, apply real-time image processing and pattern recognition tricks to it, and it then "plays" with any text it finds in the scene before displaying it on the iPhone's screen. Not impressed by the description?
