1. 1. Radiant Textiles : A framework for designing with electromagnetic phenomena

   Författare :Erin Lewis; Delia Dumitrescu; Katharina Bredies; Högskolan i Borås; []
   Nyckelord :HUMANIORA; HUMANITIES; smart textiles; interaction design; textile interaction; textile; electronic; electromagnetism electromagnetic; design methods; artistic research; Textiles and Fashion Design ; Textil och mode konstnärlig ;

   Sammanfattning : The design of smart, interactive, computational, and electronic textiles involves working with unknown variables that expand the tangible dimensions of textiles. Non-visual concepts such as electromagnetic fields, electrical current, computational code, and the temporal attributes of materials that exhibit dynamic qualities require that textile designers be able to perceive and manipulate domains of the textile that extend beyond its conventional forms of expression.
