Add Capacitive Sensing to a Digital Handset
Manufacturers are focusing on innovative techniques for replacing space-consuming buttons and switches without compromising the cell-phone user interface (CPUI). A powerful reduction technique adopts capacitive sensing into the CPUI.
Capacitive sensing enables lower cost, robustness, flexibility, and an intuitive CPUI without breaking compatibility with existing form factors and feature sets. Capacitive sensing functions can be combined with other standard functions, such as white LED driving and battery charging to further drive cost down.
