A practical digital door lock for smart home

Digital door lock plays an important role on the smart home system, not only for door guardian but also for family member incoming/outgoing awareness. However, most of the current digital door locks still keep the mechanical keyhole with digital interface to fulfill the traditional habit of key usage and consequently results in the doubt of redundant interface design. For this phenomenon, we discuss the design of digital lock and propose a mechanism to keep the traditional key usage with the digital interface. Moreover, we develop a smart-lock centered service model and create the possibility of service orchestration with the smart home system. We believe that the proposed digital door lock can survival in the power failure and provide more creative living experience.
