From the project Embroidering self-knowledge

Cala-ITU is a tangible user interface (TUI) to mediate knowledge dialogues between fashion or textile designers and traditional crafters from Cartago, Colombia. This TUI resulted from the project "Embroidering Self-Knowledge: Sistematization of experiences and participatory design of embroidery as a care practice in Cartago, Valle (Bordando el conocimiento propio: Sistematización de experiencias y diseño participativo del tejido como práctica de cuidado en Cartago,Valle)". This interface includes computational representations of the materialities and process related to the labour (fabric, needle, threads, stitches, etc.), a series of stamps (embroidered with conductive thread) that act as tangible widgets and correspond to calado stitches, and an Android App to draw and stamp the calado patterns.
