when did the first tablet computer come out
History of tablet computers The tablet computer and the associated special operating software is an example of pen computing technology, and the development of tablets has deep historical roots. 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 text recognition instead of a keyboard for working with a modern digital computer dates to 1956.[3]
