Demonstrating kirigami haptic swatches for cut-and-fold haptic feedback mechanisms

Kirigami Haptic Swatches demonstrates how kirigami and origami based structures enable sophisticated haptic feedback through simple cut-and-fold fabrication techniques. We leverage four types of geometric patterns: rotational erection system (RES), split-fold waterbomb (SFWB), the overlaid structure of SFWB and RES (SFWB+RES), and cylindrical origami, to render different sets of haptic feedback (i.e., linear, bistable, snap-through, and angular rotational force behaviors, respectively). In each structure, form factor and force feedback properties can be tuned through geometric parameters. Based on the experimental results and analysis, we implemented software to automatically generate 2D patterns for desired haptic properties. We also showcased five example applications: assistive input interfaces, rotational switch, multi-sensory toy, task checklist, and phone accessories. We believe the Kirigami Haptic Swatches helps tinkerers, designers, and even researchers to create interactions that enrich our haptic experience.
