The world we live in is likely to become one of touch according to one analyst firm.

According to iSuppli, touchscreen handsets, such as Apple’s iPhone and the new HTC Diamond are set to dominate the mobile phone market and push the global count to over 833 million within the next 5 years.

The company says the technology, which is being spurred by the popularity of Apple's iPhone will cause global shipments of touchscreen display devices to more than double from 2008 to 2012.

Despite the total of eight distinct, commercialised touchscreen technologies - i.e., resistive, surface capacitive, projected capacitive, surface acoustic wave, infrared, bending wave, active digitiser and optical imaging - even more novel touchscreen approaches are being invented.

These include new touch technologies from N-trig, Sony, Sharp, TMD and Samsung.
