摘要

电容式多点触控显示器通常不用于检测放置在其上的被动物体。事实上，这些系统通常包含主动拒绝此类输入数据的过滤器。本文对该问题进行了技术分析，并介绍了无源非接触式电容器件(PUCs)。与以前的方法不同，PUCs不需要电源，它们可以完全透明，并且不需要内部电气或软件修改。最重要的是，即使没有用户触摸它们，它们也能被可靠地检测到。

PUCs: detecting transparent, passive untouched capacitive widgets on unmodified multi-touch displays

Capacitive multi-touch displays are not typically designed to detect passive objects placed on them. In fact, these systems usually contain filters to actively reject such input data. We present a technical analysis of this problem and introduce Passive Untouched Capacitive Widgets (PUCs). Unlike previous approaches, PUCs do not require power, they can be made entirely transparent, and they do not require internal electrical or software modifications. Most importantly they are detected reliably even when no user is touching them.
