Fit for purpose? Pattern cutting and seams in wearables development

This paper describes how a group of practitioners and researchers are working across disciplines at Nottingham Trent University in the area of Technical Textiles. It introduces strands of ongoing enquiry centred around the development and application of stretch sensors on the body, focusing on how textile and fashion knowledge are being reflexively revealed in the collaborative development of seamful wearable concepts, and on the tensions between design philosophies as revealed by definitions of purpose. We discuss the current research direction of the Aeolia project, which seeks to exploit the literal gaps found in pattern cutting for fitted stretch garments towards experiential forms and potential interactions. Normative goals of fitness for purpose and seamlessness are interrogated and the potential for more integrated design processes, which may at first appear ‘upside down’, is discussed

Baker-Akhiezer functions and generalised Macdonald-Mehta integrals

For the rational Baker-Akhiezer functions associated with special arrangements of hyperplanes with multiplicities we establish an integral identity, which may be viewed as a generalisation of the self-duality property of the usual Gaussian function with respect to the Fourier transformation. We show that the value of properly normalised Baker-Akhiezer function at the origin can be given by an integral of Macdonald-Mehta type and explicitly compute these integrals for all known Baker-Akhiezer arrangements. We use the Dotsenko-Fateev integrals to extend this calculation to all deformed root systems, related to the non-exceptional basic classical Lie superalgebras.Comment: 26 pages; slightly revised version with minor correction

Diagonalization of an Integrable Discretization of the Repulsive Delta Bose Gas on the Circle

We introduce an integrable lattice discretization of the quantum system of n bosonic particles on a ring interacting pairwise via repulsive delta potentials. The corresponding (finite-dimensional) spectral problem of the integrable lattice model is solved by means of the Bethe Ansatz method. The resulting eigenfunctions turn out to be given by specializations of the Hall-Littlewood polynomials. In the continuum limit the solution of the repulsive delta Bose gas due to Lieb and Liniger is recovered, including the orthogonality of the Bethe wave functions first proved by Dorlas (extending previous work of C.N. Yang and C.P. Yang).Comment: 25 pages, LaTe

The quantum non-linear Schrodinger model with point-like defect

We establish a family of point-like impurities which preserve the quantum integrability of the non-linear Schrodinger model in 1+1 space-time dimensions. We briefly describe the construction of the exact second quantized solution of this model in terms of an appropriate reflection-transmission algebra. The basic physical properties of the solution, including the space-time symmetry of the bulk scattering matrix, are also discussed.Comment: Comments on the integrability and the impurity free limit adde

HCI at the boundary of work and life

The idea behind this Special Issue originates in a workshop on HCI and CSCW research related to work and non-work-life balance organized in conjunction with the ECSCW 2013 conference by the issue co-editors. Fifteen papers were originally submitted for possible inclusion in this Special Issue, and four papers were finally accepted for publication after two rounds of rigorous peer review. The four accepted papers explore, in different ways, HCI at the boundary of work and life. In this editorial, we offer a description of the overall theme and rationale for the Special Issue, including an introduction on the topic relevance and background, and a reflection on how the four accepted papers further current research and debate on the topic

Slow, Unaware Things Beyond Interaction

In this chapter we provide an overview of concepts and methods that have become part of our approach to gain a broader and deeper understanding of the relations between humans and technology. Over the years, our efforts have been to move past the field of interaction design’s dominant focus on human interaction with technology to develop a design-oriented understanding of human relations with technology. In our view, this begins by looking at technology beyond its functional, utilitarian, or instrumental value toward a broader set of perceptions and meanings. This theme is emblematic of a broader shift in interaction design and HCI. The first edition of this book contributed significantly to a trajectory in which designers and researchers see technology as a matter of experiences that are fun (Blythe and Hassenzahl in The semantics of fun: differentiating enjoyable experiences, 91–100, 2003), rich (Overbeeke et al. in Let’s make things engaging, 7–17, 2003), embodied (Dourish in Where the action is: the foundations of embodied interaction. The MIT Press, Cambridge, Mass, 2004), somaesthetic (Höök et al. in Proceedings of the 2016 CHI conference on human factors in computing systems. ACM, New York, NY, USA, 2016), spatio-temporal (McCarthy and Wright in Technology as experience. The MIT Press, Cambridge, Mass, 2004), hedonic (Hassenzahl in The thing and i: understanding the relationship between user and product. 31–42, 2003), reflective (Sengers and Gaver in Proceedings of the 6th conference on designing interactive systems. ACM, New York, NY, USA, pp 99–108, 2006), and ludic (Gaver et al. in CHI’04 Extended Abstracts on Human Factors in Computing Systems. ACM, New York, NY, USA, pp 885–900, 2004). However, understanding technology through more than solely a functional lens is only one part of more deeply viewing and inquiring into human-technology relations. We believe it is necessary to also understand people’s relations to technology beyond interaction and engineered experiences of technology. In the context of funology, we aim to critically and generatively contribute to the investigations of the experiences of technology to go beyond both instrumentalism and interaction. In many respects, interaction, like functionality, is too narrow of a lens for both understanding and influencing people’s experiences and relations to technology through design. Interaction is only one form of technology relations that happens explicitly, in present time, and consciously (Verbeek in What things do: philosophical reflections on technology, agency, and design. Pennsylvania State Univ. Press, University Park, Pa, 2015). What about relations to technology that manifest over time, incrementally, knowingly and unknowingly (or somewhere in between) that become part of our everyday lives
