A physical notice board with digital logic and display
Nicolas Villar, Kristof Van Laerhoven, Hans W. Gellersen · 2004
A physical notice board is augmented with digital capabilities to provide additional functionality. The notice board retains its form factor, and when used with interactive pins with controllable lights it can be used to signal to the user information about the state of documents posted on the board. Both board and augmented pins are easy to deploy and cheap to produce.
