Abstract [en]

In this architectural research exploration, we challenge the notion of an interactive architectural surface as single-layered, two-dimensional interaction interface. Instead, we propose the notion of Interactive Voluminous Substance, which moves the interaction experience into four dimensions, shifting it from far-field, proximity-based interaction to a near-field, tactile one. We present four features of architectural expression that could potentially sustain the embodiment of this Substance: spatial positioning, geometry, expression, hybrid material composition and interaction design. If the future architectural interiors and exteriors are made from Voluminous Architectural Substance, how will it be to dwell with them? We propose two physical prototypes and two interaction stories as speculative objects probing this question.

Abstract [en]

The Pliant Flesh is a piece built up with a semi-firm body onto which two layers of thinner skins are attached with electronics in between. Pressing hands onto it, it will answer pliantly however with some resistance being experienced as firm but not completely stiff. When touched the piece reacts with small vibrations and lights. The vibrations and lights are then spreading out following their own pattern. 

In the Pliant Flesh the electronics are partially visible pointing out that architecture and the technology of a building could be merged and respond to peoples actions. The piece materializes questions on what it is to experience this hybridity. The black Pliant Flesh is a complementary work to the yellow greenish piece Soft Body.

Abstract [en]

The bowels of the piece are soft with encapsulated electronics that are enclosed by a silicon skin. When pressing hands onto it the hands sink into the body. From deep within there is a respond to the pressure of the hands, slow gentle vibrations of the inner building up interaction patterns that define the tangibility. 

In the Soft Body the electronics are hidden and not clearly located. This fact together with the sense of a highly responsive and fluid material brings the Soft Body far away from what we are used to encounter within architecture of today. The piece materializes questions on what it is to experience highly tactile architecture with material and interaction inner substance and corporal connotation.

Abstract [en]

Artistic research in design is relatively new compared to experimental research in the natural sciences but it has matured a great deal over the last decade. Its extensive development has brought new challenges to professional practice, and also raised questions regarding how knowledge should be imparted in academia. By examining the field of textile design, which has traditionally been taught in close synergy with professional practice, we can discern the emergence of doctoral theses that have brought not only new perspectives to textile practice but also a new role to the design educator as a researcher within the academia. One of the challenges that design education program are facing, however, relates to creating a better connection between research and education in order to continually enrich curricula with new developments in the field, so that basic knowledge and novelty can interact. By looking closely at the development of the research environment at The Swedish School of Textiles and the interaction with undergraduate and postgraduate education, this chapter describes how research has informed the development of textile design education.

Abstract [en]

When used within textile printing, smart colours have expanded the design possibilities for textile patterns as relates to both motifs and, more importantly, uses. Smart colours suggest new functionalities and provide specific perceptions, reactions, and activities in terms of usage. At the same time, the need for peripheral information sources that are less intrusive than many of the everyday devices of the present has continuously been addressed to improve wellbeing, e.g. by making life more manageable and meaningful through the use of technology in everyday life. We aim to increase knowledge of the design qualities of smart colours, which is of use in relation to creating non- or less intrusive ways of displaying peripheral information. This paper focuses on the character of colour transition and discusses different colour-changing possibilities with regard to surface patterns; that is, from the perspectives of different levels of change and complexity and in relation to levels of intrusiveness and information comprehensibility.

Abstract [en]

This workshop will explore the design processes and tools related to textile architecture formed by wind. On one hand, we will focus on how the internal structure of textiles can affect their behaviour and geometric expression when in movement. On the other, we will experiment with diverse tools useful for designing such textile architecture in movement, ranging from digital simulations of aesthetic expressions and behaviours, through structural property assessment, up to physical models set in motion by moving air.

Textiles as design materials in architecture are considered formless. In tensile architecture, textiles are designed to follow a predesigned shape, with coated woven fabrics stretched until the resulting shape is virtually stiff; this to avoid deformation by wind. But what happens if we allow movement in the textile? What if wind becomes a design variable to decide upon the expression of textile architectural form? As a building material textile is starting to gain more interest in architecture. The possibility of creating seemingly endless variations of textiles with different behaviour and functionalities is very appealing from a design perspective. It is an easily transported and lightweight material and can be made from a range of different yarns, including reused textile fibres and wood, which gives it a great potential to be a sustainable choice for architecture.

The workshop will use a combination of computational tools using C++ code, Processing code and Grasshopper to investigate fabric geometry and behaviour at scales from the knitting and weaving of individual yarns to clothes and large-scale fabric structures. At the small scale we are focusing on topology and graph theory and at the large scale the interaction of fabric and wind is of prime interest. The emphasis is on geometry, physics and artistic expression of textile in motion. Participants will be given a simple source code which can be modified, even by those with little experience of programming. Throughout the workshop participants will get a basic introduction in different textile morphologies, and the possibility to explore different textile material behaviours, from the structure and geometries of the treads in the woven and knitted textile to the shapes and application in a building scale. The relationship between these scales will be explored both physically and digitally. How does the geometry of the threads affect the overall shape? Participants will work with both computer models as well as physical models, and gain an understanding for the geometry of the textile material, learn about different ways and means of simulating textile behaviour in movement and get a comparison of the challenges brought in by each type of simulation. A large-scale model will be produced during the workshop and exhibited during the conference.

Abstract [en]

Electroluminescence (EL) is the property of a semiconductor material pertaining to emitting light in response to an electrical current or a strong electric field. The purpose of this paper is to develop a flexible and lightweight EL device. Thermogravimetric analysis (TGA) measurement was taken to observe the thermal degradation behavior of NinjaFlex. Poly (3, 4-ethylenedioxythiophene): poly (styrene sulfonic acid) (PEDOT:PSS) with ethylene glycol (EG) was coated onto polyester fabric where NinjaFlex was placed onto the coated fabric using three-dimensional (3D) printing and phosphor paste and BendLay filament were coated 3D-printed subsequently. Adhesion strength and flexibility of the 3D-printed NinjaFlex on textile fabrics were investigated. The TGA results of the NinjaFlex depicts that no weight loss was observed up to 150°C. Highly conductive with a surface resistance value of 8.5 ohms/sq., and uniform surface appearance of coated fabric were obtained as measured and observed by using four-probe and scanning electron microscopy (SEM), respectively at 60% PEDOT:PSS. The results of the adhesion test showed that peel strengths of 4160, 3840 N/m were recorded for polyester and cotton specimens, respectively. No weight loss was recorded following three washing cycles of NinjaFlex. The bending lengths were increased by only a factor of 0.082 and 0.577 for polyester and cotton samples at 0.1 mm thickness, respectively; which remains sufficiently flexible to be integrated into textiles. The prototype device emitted light with a 12 V alternating current (AC) power supply.
