Computer-Mediated Human Architecture Interaction One of the open questions in the concept of ambient intelligence regards user interfaces to these invisible computers. If at all, how do they show up – and how does ambient intelligence in general and the user interfaces in particular change architectural space. As computers become ubiquitous or ambient, they create spatial relations towards other devices and to the place that they are located in. This paper formulates chances and challenges for both architecture and HCI. 413 213-216 213-216 Springer
