Abstract

This paper aims to present a study on digitizer styluses, mainly focused on researching the factors affecting precision. In this article, digitizer styluses are divided into two categories, capacitive stylus and electromagnetic stylus. After that, the article explains the working principle of the two styluses, and gives a further analysis, pointing out the factors that may affect the precision. For capacitive stylus, this article will mention aspects including pen tip materials, capacitive sensors, pressure sensing, self-capacitive touch, and mutual-capacitive touch. For electromagnetic stylus, we explored aspects such as sensor types and resolution, pen tip materials and structure, circuit design and signal processing, electromagnetic interference issues, and power supply stability. Furthermore, we will base on other researchers’ relevant studies on capacitive stylus and electromagnetic stylus, presenting two case studies to analyze the main factors affecting digitizer styluses. Meanwhile, this essay will also conduct a comparative analysis of the significant differences in principles between electromagnetic stylus and capacitive stylus, including their distinct performance in terms of precision. At last, the essay will conclude the overall content and conduct a try to predict the future trends of digitizer styluses in terms of precision, functionality, and user experience.
