Ubiquitous Computing and Architectural Computing have become important in the architectural processes. Data taken from sensors are used to manage devices, similarly to car technology. This paper describes terms and sensors related to ubiquitous computing in architecture. Products dealing with information visualization are introduced and fields of interest in buildings are defined. Examples of built research from previous years are investigated and critically commented on by the author. The impact on architecture is discussed and the possibility of upgrading existing buildings in their interior is described. Finally a proposal is presented with examples of doors and door handles. This design deals with the potential of an existing architectural element being used as output and input device. The author believes that there is a large market in upgrading existing buildings by replacing elements with augmented products.
