New technology is on the way to enable computers to sense the moods of drivers.
One useful application could be in sat nav systems which could use the technology to display some sympathy with a driver's state of mind and react accordingly BEFORE the driver rips out the sat nav and throws it out of the window.
Sat nav systems do not have the capability, yet, to figure out when they have directed the driver into a huge traffic jam and so keep yapping on in a very annoying manner resulting in major 'Sat nav Abuse'.
Here is an example of what we may expect of our Sat navs in the not too distant future.
Turn left in l00 yards. Turn left in l00 yards. Turn left in l00 yards. Turn left in l00 yards. Turn left in l00 yards. Turn left in l00 yards.
It is believed that very soon, when the Sat nav device has repeated the same direction 3 times, it will sense that you are in some type of difficult driving situation and, perhaps, stop talking and begin to play your favourite albums, previously programmed into the system, until a 'Commence Navigating' button is pressed.
It will then commence directing you in a kindly tone until you have calmed down and pressed the 'I'm calm now' button.
Then, and only then, will regular service be resumed.
