Multi-touch all-point sensing in automotive environment

Multi-touch all-point sensing is an extension of capacitive sensing which has made it possible for touch technology to become much more intuitive by sensing the presence of multiple fingers simultaneously and being able to recognize gestures. This article covers the basics of capacitive sensing and the evolution of touch sensing technology in automotive environments. After discussing the construction and internal operation of a multi-touch touchscreen/trackpad, it will also address the paradigm changes brought about by multi-touch all-point sensing in human machine interfaces (HMIs).
