This workshop will explore the use of low-cost materials and tools to build textile-based interfaces. We will introduce a range methods for handcrafting textile sensors and circuitry. Participants will learn techniques developed by the workshop leaders and will also be encouraged to use our material library to design their own custom sensors. The goal of the workshop is to familiarize participants with available electronic textile materials and introduce them to a variety of sensor and circuitry construction techniques. Keywords DIY, sensors, soft circuitry, craft, handmade, conductive materials ACM Classification Keywords H5.m. Information interfaces and presentation (e.g., HCI): Miscellaneous.
