Lately, a physical scientist from NASA has announced success in creating and connecting an external chemical sensor to iPhone at OS ver 3.0. The sensor is a piece of chip circuit board at a size of a postal stamp. It is connected to iPhone via its 30-pin dock connector and communicates with a dedicated application run on iPhone OS 3.0. The sensor is said to be able to detect several chemicals such as ammonia, chlorine gas and methane.
iPhone has been adding up credits on its flexibility on software and hardware extensions. Besides over 20,000 game and entertainment apps available via Apple App Store, third-party software makers are flocking to contribute multifarious programs for this all-purpose handset. iPhone's superior multi-touch design, stylus-free 3.5" wide screen, optimal programming environment and easy extensibility are the stimulus for the creative and innovative ideas sparked towards it. We have seen people on the bus, in the street playing iPhone as a game device. We may be not surprised with the fact that iPhone's dear twin iPod is frequently favored by the U.S. Army as a field translator in local Iraq. But we may be interested in some odd occasion where iPhone is used. It is like English famous painter David Hockney who developed his inspirations drawing on his iPhone. And now it seems it will reduce the need to manufacture expensive chemical sensor devices and iPhone is just equally functional with just a compact chip plug-in.
We may now all bear the same question: where will iPhone go? Since it is so universally welcomed with ingenious design in its blood, I am sure it will collect more usability and become more like an infinite transformable device in the future.
