The history of tablet computers and the associated special operating software is an example of pen computing technology, and thus the development of tablets has deep historical roots.[1] The first patent for a system that recognized handwritten characters by analyzing the handwriting motion was granted in 1914.[2] The first publicly demonstrated system using a tablet and handwriting recognition instead of a keyboard for working with a modern digital computer dates to 1956.[3]
