Intuitive door entry system using PAN

Usability means that the shape of a design indicates its usage. In light of this concept, we introduced an intuitive key-less entry system using PAN (personal area network) technology. When turning a door knob for the purpose of opening a door, the PAN sends an entry data through a human body. This reduces unnecessary action as well as entry time for door opening. To confirm the efficacy of this concept, we developed a simple demonstration circuit.
