8.1 Introduction
With the release of the Apple iPhone in 2007, a new mark in multi-touch was set. This phone alone may have marked the beginning of multi-touch "everywhere" – pervasive multi-touch in our daily lives. However, multi-touch has a long and rich history of development that is important to mention. It is also important to mention current trends in multi-touch as well as the technology behind some of the multi-touch hardware.
