Description An interactive door
Author(s)  Ricky Ng-Adam

Physical computing is all about interactions human-machine... A door is one of the most common thing that humans interact with and is a promised of something worth seeing. How can the experience be improved or modified? Even locked, a door can be interactive. A door has a large surface area that can be augmented with sensors, displays, lights. A door is a large canvas that can painted, decorated and designed to be attractive. A door, locked or open, can interact with both users and passerby. A door access can be granted remotely, through possession of a physical object or through interactions in specific sequences. A door can display information and post information about its state, its sensors and environmental sensory input. A door state, locked or unlocked, is significant.


  • Servos and motors can be used to lock and unlock the door
  • RFID reader can be used to grant access
  • LCD (Nokia) displays can be embedded in the door to show text messages
  • Ethernet shield connectivity can be used to post status updates to the Internet ("the space is opened", "the space is closed", "30 persons walked through the door today)
  • Door knob can be made out of an original 3D design and "printed" using the CNC mill
  • Flex sensors can be used to design a different type of keypad (flexing pieces of fabric)
  • LEDs can add animation (infrared or not) to outline expected activities
  • Infrared collision detection sensors or motion sensors can detect people walking by the door
  • Mesh network can integrate into some home automation (close/open lights on door close/open)
  • Voice recorder/player can add audio interactions (such as adding the ability to leave audio messages)
  • Electronic "blinds" can be added
