Research And Implementation To Digital Ink's Writing And Painting Based On Force Information

Pen user interaction is a kind of natural human-centric interacting manner and it has characteristic of convenience, naturalness and controllability. F-Tablet is a kind of handwriting input device based on force information, by which computer will convert the force information during writing into handwriting script and display. Digital ink is an original technology of human computer interaction, which saves dynamic information during writing as the form of ink. This thesis will research on the digital ink's writing and painting based on the force information of handwriting script collected by F-Tablet. The main works of this thesis are as follows:(1) Relavant content of human computer interaction was summarized and present study situation of pen user interaction was described. Furthermore, the structure and principle of F-Tablet was analyzed in detail.(2) The technology of digital ink and its marked language InkML was researched and the information of trace, channel, device and user on F-Tablet was described based on InkML.(3) The implement method of digital ink's writing and painting on F-Tablet was studied in detail, including communicating manner of F-Tablet, sampling and saving of force information, diaplaying and editing of handwriting and graphics on F-Tablet.(4) Relavant software was designed, so as to show the implementation of digital ink's writing and painting based on handwriting's force information collected by F-Tablet.
