Tiles prototype

Smart Architecture is characterized with their adaptability to users' needs. The interaction between users and their living environments are redefined so that buildings are autonomously responsive to human activities. Floor, as the very construct where human-building interactions take place most frequently, is chosen to initialize our attempts to make buildings "smart". We applied the concept of Cellular Automata to develop the prototype of "Smart Tile", which can be connected to each other to form an information network so that activities takes place at somewhere on the floor can be recognized and disseminated to wherever the information is needed. Most importantly, a smart floor records the dynamic configuration of interior spaces that are filled with movable objects and people.
