Appearance-Independent Tactile Design Using Different Embroidery Stitches
Résumé
We present a novel method to enhance the tactile properties of fabric interfaces through embroidery, enabling appearance-independent tactile design. Unlike existing approaches that alter geometric properties, such as shape or contours, our method uses commercially available embroidery techniques to achieve tactile variations while preserving the visual consistency of the fabric. By adjusting parameters like stitch length, density, and deviation, we establish a design space for reproducible and tactilely diverse embroidery patterns. Our user study, involving 26 embroidered samples, demonstrates how different stitching techniques influence tactile perception, including qualities like smoothness, roughness, and directional guidance. Attendees will experience several use cases at the demonstration, such as eyes-free interfaces for sliders and directional keypads, tactile learning tools for children, and assistive applications for visually impaired individuals. This work highlights the potential of embroidery as a versatile and practical solution for designing tactilely engaging fabric interfaces.
