Wherever you turn these days people are talking about "the internet of things" and "wearable computing". Typically what people are on about is either Google Glass or the much whispered about but totally unknown entity referred to as the "iWatch". Of course most people are wondering why one would want to bother with another piece of computing equipment, like a smart-watch, that you would have to charge constantly, synchronize and otherwise take care of incessantly, as if our smartphone didn't require enough attention already.
To me some of the answer came a few days ago when Apple introduced CarPlay. The idea behind CarPlay is to provide you an in-car user experience that is consistent with what you have come to expect from your iPhone. But make no mistake: the brains of this system remains your iPhone. CarPlay itself is not an independent computer system in your car. It simply projects iPhone controls onto your car dashboard system.
And that is how I imagine Apple's next step into wearable computing will be as well. Assuming it is a watch, it could very well be something like this extremely well thought out concept by Mr Gabor Balogh of Budapest, Hungary. All the watch needs to be is a window into some of your iPhone's functionality, and preferably with an elegant interface (as in this concept).
But somehow I have a feeling that Apple will go much further. As described in this piece in The Economist, the possibilities for true wearable computing are endless, and focusing only on glasses or watches is showing a lack of imagination.
