Abstract

In this paper, the design and realization of a sensing device for recording dynamics characteristics of handwriting is developed. The device is realized with light materials for embedding forces and inertial sensors in small space. A microsystem based on cortex M3 processor is realized to perform data acquisition of the measured signals and to carry out the data via serial transmission to a Notebook for subsequent signal processing. First experimental results have shown the effectiveness of the proposed device for recording accelerations in 3D, angular velocities in pitch and roll, the pressure of index and thumb and the reaction force on a plane surface. For instance, subjects of different ethnic and different skill have been taken into account for handwriting behavior study.
