S-pen is Samsung’s stylus pen which was introduced first in 2011 through the launch of galaxy note. In galaxy note 1, S-pen focused on its previous role in writing, drawing a picture and etc. S-pen also advanced as new Note series was introduced each year. Tool tip became thinner and writing sensitivity improving as pen-pressure was progressed from 256 up to 4096 level.
The use of S-pen did not limit itself from writing but it maximized its usability by integrating various technologies and provided an independent function. It wanted to suggest a new paradigm for use of S-pen such as preview, collection of variety contents and etc other than writing function.
