A Review: Electric Field Sensing for Human-Computer Interaction Applications

Human-computer interaction (HCI) in invasive computing system has been proving as a dynamic research interest since the late nineties. The interference of a human body intercepting the way between a transmitting electrode having low frequency and a receiving electrode changes the displaced current which is computed at the receiving electrode. The procedure of human body interfacing with electric fields of low frequency could be implemented to make an extensive area of interactive fields namely human computer interface, virtual reality, interactive surfaces as well as automotive applications. This paper aims to make an overview of some electric field sensing techniques along with their applications including Human-Computer Interaction (HCI) procedure as well as the evaluation of the robustness of the applied techniques.
