Handwriting was a communication technology, historically created and developed in human society, and basically consists of registering marks in a paper holder.
This technology had as main objective the recording of information, however it can not be denied the contribution that it had in the construction of knowledge.
Handwriting is thought to have come from simple ideogram designs: for example, the design of an apple would represent the fruit itself, and a two-legged drawing could represent both the concept of walking and standing. After a while the symbols became more abstract, eventually evolving into symbols with no apparent relation to the original characters.
