Multi-Way Interactive Capacitive Touch System with Palm Rejection of Active Stylus for 86" Touch Screen Panels

📋 论文概要

针对86英寸大尺寸触摸屏面板，提出了一种多路交互式电容触摸系统（MI-CTS），支持主动笔输入并实现了手掌误触抑制功能，解决了现有系统无法同时进行实时多路交互以及主动笔使用中的手掌误触问题。

💡 主要创新点

• 首次实现了多路交互式电容触摸系统（MI-CTS），支持在86英寸大屏幕上多用户同时实时交互。
• 提出主动笔的手掌误触抑制（palm rejection）方法，提高书写和绘图体验。

Multiple-way interactive CTSs (MI-CTSs) that can simultaneously communicate with each other on a real-time basis have been demanded; however, such MI-CTSs have not yet been reported. In addition, palm rejection in an active stylus would be a very useful feature for when the palm inevitably touches a touch screen panel (TSP) [5]. In this paper, an MI-CTS with the palm rejection for an active stylus is reported. This allows simultaneous interaction between CTSs on a real-time basis, while lessening the computational load. Figure 10.3.1 shows a block diagram of the MI-CTS with multiple CTSs, each of
