This work presents a new simple passive 3Dstylus and its associated stroke reconstruction algorithm for capacitive touch panels that detects the -directional position and -directional strength without the help of a pressure sensor. The proposed algorithm can successfully detect touch information while eliminating noise.Moreover, unintended touch will be recognized and its effects are eliminated while the desired signal will be accessed by the touch system to enhance the handwriting experience. The results of experiments on a touch panel system were analyzed, demonstrating the effectiveness of the proposed stylus and its stroke reconstruction algorithm.
