A New Generation of Touch Screen Phones

Phones are getting cleverer. They can not only receive calls, but send texts, emails, connect to the internet, play music, take pictures and so much more.

Many smart phones today including phones like the latest iPhone and the BlackBerry are touch screen. This can mean that when you need to call someone, and you are standing next to someone with an iPhone, you look a little 'primitive' and you may get the odd stare.

A pile of old mobile phones But fear not, your favourite tech blog has a solution! Engineers from Cambridge University have developed a way to turn a normal phone, into an all singing, all dancing, touch screen phone.

This means that your old phone can be new again. A new generation of retro phones. People will actually want to buy cheap old phones again - well... possible.

Oops - I forgot to mention how! Well what these researchers have developed is a piece of software that you can add to your phone and it will make it touch screen. How? Guess.

Yeah, I tried that, and it didn't get me anywhere. What the software does is listen to where your finger taps on the screen. Clever I know. Using your phones microphone, this software can tell where your finger is on the screen, interpret that, work out what you would have clicked and then perform that function. What a great little bit of tech!

If the technology is developed further and is in popular demand, it could mean that you would be able to turn your mobile into a touch screen in very little time, for a tiny cost. Just a quick calibration and you are off! This could be very bad for mobile phone retailers though, as it could bring a massive drop in sales, especially of the top of the range smart phones.
