    Abstract: Home security is one of the most critical concerns in daily life. In this paper a novel human–machine interface was integrated in a home-security system. The developed system applies the action of knocking as the input interface to unlock a door without using keys. First, the unlock areas on the door are set. When a user knocks on the door, the system obtains knocking information from six vibration sensors in the door. A pattern-recognition algorithm subsequently identifies the knocking pattern of the user, including the knocking areas and the knocking sequence. According to the simulation results, the accuracy of identifying the correct knocking areas was between 90% and 93%.
