Research on the Method of Pen Gestures Design and Recognition for Human-Computer Interaction

In the pen-based interactive system, using pen gestures is an important means of interaction. With the development of mobile computing, pen gesture recognition and applications are getting more and more attention gradually. This paper firstly analyses the design principles of pen gestures from the perspective of both users and computers, then designs a set of pen gestures for chemistry teaching. Based on Rubine recognition algorithm, this paper includes scale normalization and excludes the impact of irrational assumptions of Rubine algorithm, so that the recognition rate increased by 1.7 percent. While adding the user login and other user-style-based recognition processing, enhances the accuracy of the pen gestures interaction.
