Towards media architecture

Navigating Interactive Story Spaces

Over the past decade, journalists have created in-depth interactive narratives to provide an alternative to the relentless 24-hour news cycle. Combining different media forms, such as text, audio, video, and data visualisation with the interactive possibilities of digital media, these narratives involve users in the narrative in new ways. In journalism studies, the convergence of different media forms in this manner has gained significant attention. However, interactivity as part of this form has been left underappreciated. In this study, we scrutinise how navigational structure, expressed as navigational cues, shapes user agency in their individual explorations of the narrative. By approaching interactive narratives as story spaces with unique interactive architectures, in this article, we reconstruct the architecture of five Dutch interactive narratives using the walkthrough method. We find that the extensiveness of the interactive architectures can be described on a continuum between closed and open navigational structures that predetermine and thus shape users’ trajectories in diverse ways.

Embedding Privacy in ICT architectures.

According to Johnson & Grandison (2007), failure to safeguard privacy of users of services provided by private and governmental organisations, leaves individuals with the risk of exposure to a number of undesirable effects of information processing. Loss of control over information about a person may lead to fraud, identity theft, reputation damage, and may cause psychosocial consequences ranging from mild irritation, unease, social exclusion, physical harm or even, in extreme cases, death. Although pooh-poohed upon by some opinion leaders from search engine and ICT industries for over a decade (Sprenger, 1999; Esguerra, 2009), the debate in the wake of events like the tragic case of Amanda Todd could be interpreted as supporting a case for proper attention to citizens’ privacy. Truth be told, for a balanced discussion on privacy in the age of Facebook one should not turn towards the social media environment that seems to hail any new development in big data analysis and profiling-based marketing as a breathtaking innovation. If the myopic view of technology pundits is put aside, a remarkably lively debate on privacy and related issues may be discerned in both media and scientific communities alike. A quick keyword search on ‘privacy’, limited to the years 2000-2015, yields huge numbers of publications: Worldcat lists 19,240; Sciencedirect 52,566, IEEE explore 71,684 and Google scholar a staggering 1,880,000. This makes clear that privacy is still a concept considered relevant by both the general public and academic and professional audiences. Quite impressive for a subject area that has been declared ‘dead’.

How architecture can improve the quality of life of individuals showing challenging behaviour

Challenging behaviour, such as aggression towards oneself, others, or objects, arises in interaction with the environment and may prevent individuals from participating in society and compromise their quality of life (QoL). Literature suggests that architects can contribute to prevention, by influencing challenging behaviour before rather than after its occurrence. By conducting a case study at a very-intensive-care facility, we explore how architecture can contribute to the QoL of intellectually impaired (and autistic) individuals showing challenging behaviour. The case study is based on interviews with residents and care providers, and direct observations of their daily life. Preliminary findings confirm the relevance of architecture in influencing challenging behaviour. They suggest that the residents are dependent on the (visual and auditory) connection with the care provider. Also, care providers confirm the importance of this connection for the quality of the care they provide. At the same time, residents may experience anxiety triggered by fellow residents and their challenging behaviour. Residents may also feel stress when faced with unexpected situations and this may lead to an onset of challenging behaviour. Sensory sensitivity, specifically to noise and heat is also relevant for their QoL.The findings will be further substantiated through multiple triangulation with available data (personal files, incident reports, photographs). Future research, specifically focused on intellectually impaired individuals showing challenging behaviour, is needed to better understand the similarities and differences between their needs and the needs of autistic people.

Resource-Efficient Image Buffer Architecture for Neighborhood Processors

Neighborhood image processing operations on Field Programmable Gate Array (FPGA) are considered as memory intensive operations. A large memory bandwidth is required to transfer the required pixel data from external memory to the processing unit. On-chip image buffers are employed to reduce this data transfer rate. Conventional image buffers, implemented either by using FPGA logic resources or embedded memories are resource inefficient. They exhaust the limited FPGA resources quickly. Consequently, hardware implementation of neighborhood operations becomes expensive, and integrating them in resource constrained devices becomes unfeasible. This paper presents a resource efficient FPGA based on-chip buffer architecture. The proposed architecture utilizes full capacity of a single Xilinx BlockRAM (BRAM36 primitive) for storing multiple rows of input image. To get multiple pixels/clock in a user defined scan order, an efficient duty-cycle based memory accessing technique is coupled with a customized addressing circuitry. This accessing technique exploits switching capabilities of BRAM to read 4 pixels in a single clock cycle without degrading system frequency. The addressing circuitry provides multiple pixels/clock in any user defined scan order to implement a wide range of neighborhood operations. With the saving of 83% BRAM resources, the buffer architecture operates at 278 MHz on Xilinx Artix-7 FPGA with an efficiency of 1.3 clock/pixel. It is thus capable to fulfill real time image processing requirements for HD image resolution (1080 × 1920) @103 fcps.

Keep it looking beautiful! Historicised residential architecture as a means of reproducing the middle class self

This paper explores how residents of Helmond Brandevoort, a neotraditional neighbourhood in the Netherlands, socially construct a 'classed' place identity and what role the historicised architecture plays within that process. Given that place identity is constructed through social and cultural practices, the paper argues that residents' consumption of historicised environment is bound up with drawing symbolic boundaries which were explored here by analysing residents’ narratives. Two prominent types of narratives were found: their aesthetic judgement of the residential environment and the way they use it. Through these layered narratives, all interviewees appear to use historicized aesthetics to classify themselves as part of a valued social category. In the neighbourhood explored, the way of boundary drawing based on fostering moral judgements of social behaviour accompanied by efforts to keep neighbourhoods' historicised image unchanged.
