Storytelling techniques within traditional broadcast media have not made major advances in recent years due to the linear and relatively rigid approach to narrative despite advances in the technology that delivers the content. This research proposes the concept of ‘perceptive media’ in which the content creators have at their disposal different tools and sensors to allow for the subtle adaption of the narrative without any direct interactions from the audience members. The concept is demonstrated through the creation of a ‘perceptive radio’ that is able to play specially designed content that adapts to the physical and social context in which the radio resides.

This paper considers the increasing utilisation of games design as an approach to encouraging behavioural change through design. In particular it considers how to address issues that cannot be reduced to easily actionable personal goals such as climate change and are often termed ‘wicked problems’ by designers due to their innate complexity. This paper presents a research through design approach that focuses on rhetoric within the design of a mobile phone game - Cold Sun. Thus the aim is not to examine the utility or usability of the game but rather offer it as an example of a design approach we believe is desirable and productive for future practice. Cold Sun provides an example that illustrates how scientific and real world data can be integrated into game mechanics to enhance the rhetoric of the game by engaging the player at a more personal level. Thus Cold Sun allows players to effectively rehearse issues of climate change that will affect their plausible futures, and thus develop a greater understanding of some of these complex issues and consider ways to respond.

The paper describes an innovative pervasive game which uses both GPS and heart-rate monitoring in a mobile device. The objectives of the game’s development include a health science agenda concerned with the player’s wellbeing and physical activity, prompted by increasing concern over the health consequences of modern ways of living. Game design issues concerned with the use of heart-rate data are discussed, focusing on the meanings which can be extracted from the data and how these may be represented for effective gameplay.

A new pervasive digital game is discussed, relating technical and conceptual innovation. A combination of sensor technologies enables a responsive visual and auditory environment to be overlaid on the real world. This allows processes within the player's body to be mapped to the environment through which the player passes, externalising the internal. Rather than using technology to replicate the rigid goals and structures of many conventional games, this game explores the concept of 'open play', a form of personal exploration. The work is an interdisciplinary collaboration between digital artists and health scientists with an agenda to alter players'attitudes to the body and health as well as to break new ground artistically.

We report a combined non-local (PBE-TC-LRC) Density Functional Theory (DFT) and linear-response time-dependent DFT (LR-TDDFT) study of the structural, electronic, and optical properties of the cation-vacancy based defects in aluminosilicate (AlSi) imogolite nanotubes (Imo-NTs) that have been recently proposed on the basis of Nuclear Magnetic Resonance (NMR) experiments. Following numerical determination of the smallest AlSi Imo-NT model capable of accommodating the defect-induced relaxation with negligible finite-size errors, we analyse the defect-induced structural deformations in the NTs and ensuing changes in the NTs' electronic structure. The NMR-derived defects are found to introduce both shallow and deep occupied states in the pristine NTs' band gap (BG). These BG states are found to be highly localized at the defect site. No empty defect-state is modeled for any of the considered systems. LR-TDDFT simulation of the defects reveal increased low-energy optical absorbance for all but one defects, with the appearance of optically active excitations at energies lower than for the defect-free NT. These results enable interpretation of the low-energy tail in the experimental UV-vis spectra for AlSi NTs as being due to the defects. Finally, the PBE-TC-LRC-approximated exciton binding energy for the defects' optical transitions is found to be substantially lower (up to 0.8 eV) than for the pristine defect-free NT's excitations (1.1 eV).

Despite chalcopyrite (CuFeS2) being one of the oldest known copper ores, it exhibits various properties that are still the subject of debate. For example, the relative concentrations of the ionic states of Fe and Cu in CuFeS2 can vary significantly between different studies. The presence of a plasmon-like resonance in the visible absorption spectrum of CuFeS2 nanocrystals has driven a renewed interest in this material over recent years. The successful synthesis of CuAl1−pFepS2 nanocrystals that exhibit a similar optical resonance has recently been demonstrated in the literature. In this study, we use density functional theory to investigate Fe substitution in CuAlS2 and find that the formation energy of neutral [FeCu]2++[CuAl]2− defect complexes is comparable to [FeAl]0 antisites when p≥0.5. Analysis of electron density and density of states reveals that charge transfer within these defect complexes leads to the formation of local Cu2+/Fe2+ ionic states that have previously been associated with the optical resonance in the visible absorption of CuFeS2. Finally, we comment on the nature of the optical resonance in CuAl1−pFepS2 in light of our results and discuss the potential for tuning the optical properties of similar systems.
