Getting In Touch With Designing Capacitive Sensing Interfaces
Capacitive sensing is making its way into more and more uses everyday. These sleek user interfaces are growing in popularity for PMPs, mobile handsets, computers, point-of-service terminals and other home electronics, and are now showing up in industrial and medical applications as well. Capacitive sensing is a form of touch-based sensing. It's an alternative to traditional mechanical buttons and sliders. In addition it can be used to create touch screens, touchpads and proximity sensing. Instead of sensing the physical state of a button, it detects the presence or absence of a conductive object, in many cases a user's finger. This article looks at how capacitive sensing works.
