    abstract     = "Smart door locks that can unlock doors from a smartphone have recently been introduced to the market. Their main weakness is that they still require the user to press a button on their phone to unlock the door, what if this could be done automatically. This project first analyzes current and upcoming sensors in smartphones that may be able to help unlocking automatically and positioning techniques that do not rely on {GPS}. Then the Android operating system is analyzed for its capability to provide information from Bluetooth, Wifi, {GPS,} network location, and inertial sensors. A prototype framework application that can make a choice based on data collected from these sensors is then designed and implemented. Finally the accuracy of sensors and application is tested and evaluated."
