    Design Potentials of Magnetic Yarns2018In: : 8th European Conference on Protective Clothing, May 7-9, Porto, Portugal, 2018Conference paper (Refereed)
    Abstract [en]

    Introduction

    Magnetism holds a strong potential as a design material due to the array of possible expressions based on its fundamental behaviours of attraction and repulsion. The magnetic phenomenon presents itself simultaneously as visual and non-visual material through its quality of being imperceptible under certain conditions until manifested in some way, such as physical interaction or electronic control. This balancing of physical constants, material and immaterial considerations of magnetic phenomenon, become a rich site for exploration and experimentation when combined with the immense variables available in textile design such as yarn attributes (yarn number, yarn twist, fiber composition) and textile structure (woven, non-woven, knit, twisted and interlaced). Therefore, the use of magnetism as a design material holds a strong potential for dynamic and responsive textile expressions when used in composition with one another. While the discourse surrounding the material-immaterial relationship is active and present across various design disciplines [1,2,3], the representation of magnetic phenomenon as a design material remains underrepresented in the field of textile design. This experiment illustrates a method of creating yarns that are responsive to magnetic fields through a process of hand-painting natural, synthetic, and combination yarns with a widely-available ferromagnetic solution. The result is a reference catalogue of yarns exhibiting design potentials for textile-based magnetic interactions.

    Experiment

    This poster presentation describes a method of creating yarns that are responsive to magnetic fields through a process of hand-painting natural, synthetic, and combination yarns with a widely-available ferromagnetic solution. The yarns measure 10 cm in length and are grouped in bundles to form tassels. They are anchored to a fixed structure at a central point from which all movement arises. A magnetic field is applied to the yarns through the use of permanent- and electro-magnets. These painted yarns exhibit a unique variety of behaviours and characteristics ranging from lifting/dropping, expansion/compression, splaying, and fluctuating movements, as well as the yarn’s ability to hold structural form. These expressions are based on the yarn variants of fiber composition, weight, twist, flexibility, absorption ability, and evenness of absorption.

    Results

    This experiment results in a catalogue of natural and synthetic yarn attributes pre- and post- ferritic treatment, which identities their magnetic and behavioural abilities. The results suggest design potentials to be further explored through textile construction methods such as weaving and knitting.

    Kinetic Body Extensions for Social Interactions2018Conference proceedings (editor) (Refereed)
    Abstract [en]

    This studio invites participants to explore ways of extending physical expressivity through a combined use of wearable electronics and structural textile design. Participants are introduced to an electronics and material prototyping method developed by Social Body Lab for constructing kinetic textile body extensions intended for use in social interactions. Participants will learn to use a servo motor in combination with folded and pleated paper, textiles, and structural materials to create a kinetic wearable module that can expand and contract in form. These kinetic modules can vary in size, form, complexity, and placement on the body, depending on the intended application. Pressure, flexion, ambient light, and electromyography (EMG) are sensors that will be explored as possible triggers for these modules using body movements and gestures. Through prototyping, testing, wearing, and group discussion, participants will explore ways in which their kinetic body extensions can amplify, extend, or subvert existing body language.

    Magnetic Textiles: Exploring the Non-Visual in Textile Design

    Instructor: Erin Lewis

     

    This workshop will explore the design possibilities of magnetic phenomenon in textile design. Magnetic phenomenon holds the quality of being imperceptible until manifested in some way, such as through physical interaction. This phenomenon presents itself as a non-visual material, and, paradoxically, as a physical material to be utilized in design. The inclusion of magnetic threads in textile constructions allow for hidden attributes to be expressed, for example through kinetic behaviours and haptic feedback, which thereby enhance the dimensions of design available to us. This area of non-visual material exploration becomes particularly rich when combined with the variables specific to textile design such as yarn compositions, structure, and texture.

     

    In this workshop students will work with magnetic and non-magnetic threads, wires, or yarns, to create a series of magnetic textile design samples using one or more textile construction technique(s) of their choosing (e.g. knitting, crochet, weaving, etc.). Students will design textiles that emit sound waves or electromagnetic radiation, or that are kinetically actuated through the use of neodymium magnets. Students will have both independent and supported work periods. Samples will be presented on the last day of the workshop in a group critique format.

    Sound-Based Thinking and Design Practices with Embodied Extensions2020In: Sound-Based Thinking and Design Practices with Embodied Extensions, ACM Digital Library, 2020Conference paper (Refereed)
    Abstract [en]

     The discourse surrounding intangible materials in interaction design is often directed toward

    computational materials [2, 9], however, this studio focuses on sonic and electromagnetic fields as

    intangible materials with distinctive qualities and methods of interaction. Participants explore the

    notion of extended body by augmenting their natural hearing abilities through body-space-object

    interactions. Using analog and radio-frequency (RF) sonic extenders, participants direct, block,

    amplify, and filter sounds, and perceive the surrounding electromagnetic landscape, thereby

    creating a “super sense” of heightened audition. This sonic experience explores the sensorial

    possibilities of the future body, where aural augmentation could take place. Using soundwalking

    and soundmapping as methods, participants explore transitive sonic forms that change their

    qualities and content over time in downtown Sydney. Participants produce a collective soundmap

    identifying embodied sonic extensions and acousmatic techniques, along with movements,

    gestures, and choreographies. This data will be used to stimulate a final discussion.
