But even the best multitasker will find it tricky to keep an eye on the phone's screen as well as the path ahead - now, thanks to Apple, you won't have to stop, just download their new application Email 'n' Walk and keep moving.

This package takes a live feed from the phone's camera which is mounted on the rear of the device, to show the user what's in front of them as they type, according to a report in the 'New Scientist'.

In fact, the text of the email appears as white lettering superimposed on top of the video feed - and is more than clear enough to read without blocking view of the path or road ahead.

This way one can type and walk without worrying about what may be in front of one. Once one's finished composing the message, one has to tap the send button and the message will be placed into the iPhone's Mail application where one can add recipients and send it away, say its developers.

The application works surprisingly quick when sending the message to one's iPhone's Mail application, so even if one is still moving one can get the email sent rather smoothly.
