Human Vehicle Interaction Based On Electric Field Sensing

The intervention of a human body part entering the path between a low frequency transmit electrode and a receive electrode causes a change in the displaced current measured at the receive electrode. This method of human interaction with low frequency electric fields can be used to create a wide range of interactive applications including human computer interfaces, interactive surfaces, musical instruments, virtual reality and automotive applications. This paper presents a review of electric field sensing techniques and applications involving Human Vehicle Interaction (HVI). The HVI applications are split into three categories: proximity sensing and touch detection; gesture recognition; user discrimination.
