Interaction design is increasingly about embedding interactive technologies in our built environment; architecture is increasingly about the use of interactive technologies to reimagine and dynamically repurpose our built environment. This forum focuses on this intersection of interaction and architecture

This paper presents a first step in the development of a methodology to compare the ability of different sonifications to convey the fine temporal detail of the Electroencephalography (EEG) brainwave signal in real time. In EEG neurofeedback a person‟s EEG activity is monitored and presented back to them, to help them to learn how to modify their brain activity. Learning theory suggests that the more rapidly and accurately the feedback follows behaviour the more efficient the learning will be. Therefore a critical issue is how to assess the ability of a sonification to convey rapid and temporally complex EEG data for neurofeedback. To allow for replication, this study used sonifications of pre-recorded EEG data and asked participants to try and track aspects of the signal in real time using a mouse. This study showed that, although imperfect, this approach is a practical way to compare the suitability of EEG sonifications for tracking detailed EEG signals in real time and that the combination of quantitative and qualitative data helped characterise the relative efficacy of different sonifications.

One of the rare representational problems encountered during the construction of axial representations of architectural configurations in space syntax is the so called 'visibility accessibility problem'. This is the condition when it is possible to perceive a space but not be able to directly traverse to that space. This condition arises in a number of cases for example in an office with half height partitions, or glass walls, in an urban street where safety barriers prevent free pedestrian movement or in a multi-storey building with an atrium which permits the direct perception of spaces on the second or story but not provide direct access to them. This paper introduces a new spatial representation called the multi-layered network that is asserted to be a more general representation of topological spaces than previous representations. Proofs are argued for certain aspects of the representation that is based as an extension of current topological representations and computations. A software implementation of this representation is demonstrated with a number of examples from the problematic cases. Finally it is argued that this new multilayered representation could also be used as the basis for a spatial representation which included signage and so by extension could make

Musical harmony is considered to be one of the most abstract and technically difficult parts of music. It is generally taught formally via abstract, domain-specific concepts, principles, rules and heuristics. By contrast, when harmony is represented using an existing interactive desktop tool, Harmony Space, a new, parsimonious, but equivalently expressive, unified level of description emerges. This focuses not on abstract concepts, but on concrete locations, objects, areas and trajectories. This paper presents a design study of a prototype version of Harmony Space driven by whole body navigation, and characterizes the new opportunities presented for the principled manipulation of chord sequences and bass lines. These include: deeper engagement and directness; rich physical cues for memory and reflection, embodied engagement with rhythmic time constraints; hands which are free for other simultaneous activities (such as playing a traditional instrument); and qualitatively new possibilities for collaborative use.
