Title
PUCs demo: detecting transparent, passive untouched capacitive widgets
Abstract
Capacitive multi-touch displays are designed to detect touches from fingers that often change the location. This is quite the opposite of our goal: detect passive objects placed on them. In fact, these systems usually contain filters to actively reject such inactive 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.
