Have you considered what to do when you are out in the cold weather wearing your gloves and your iPhone rings? Well, Rob Griffiths has some good ideas :-):
The temperatures outside are dropping rapidly, and many of you will find your hands wrapped in thick gloves. And then suddenly, an important phone call drops in. Unless you’ve plugged in your earphones, or connected your Bluetooth headset to the iPhone, it will take quite a long time to get your hands free to slide the button to speak. So how to answer this important call quickly?
There are “alternative” ways to interact with your iPhone without having to uncover your fingers. For basic actions such as accepting a phone call or unlocking it to read a text message, you can use either your nose or, for some more precise gestures, your tongue. I know this isn’t the most elegant way to operate your beloved iPhone, but in some cases, it needs to be quick and dirty…
For those of you finding this disgusting, but still don’t want to run around with cold fingers, consider buying some fancy iPhone-enabled Dots Gloves.
