Development of a New System for Handwriting Information Collection

The useable information of most Pen User Interfaces mainly consists of pen point trajectories and pressure. However, the handwriting is created dynamically, meanwhile, velocity, acceleration and force are changing during the handwriting generating. Actually when the pen point does relative motion to the paper, the motion between pen point and paper contain three-dimension force vector, the position of pen points and velocities, etc. Pen User Interface could not only acquire trajectories of pen points, but also obtain the contact force and the force direction, researchers could extract more abundant personalized features. Based on the innovative force information acquisition ie Force-Pen, this study designs a new handwriting information collection system which is offered by the Force-Pen.
