This project demonstrates a design tool that aids the design and simulation of waxpaper actuators. The waxpaper actuator is a sequentially-controllable, moisture-triggered, rapidly-fabricated, and low-cost shape-changing interface. We introduce a design tool that integrates the characteristic data of the waxpaper actuator to aid users in the customization of swift personal actuators. It uses gray levels to control the wax interface’s deformations, bending degrees and response times. Users can design their own actuators or import samples we provide, customize variables to best fit their needs, and create simulations to preview the performance. This gives higher precision to the effectiveness of the waxpaper actuator before it is fabricated. This makes the technique more accurate and accessible to future HCI projects.
Mechanism of the design tool.
(a) Relationship between bending curvature and responding time for waxpaper samples with front side gray levels from 10% to 50% with one time spray
(b) Morphing process for waxpaper samples with front gray level of 10%. Sample size for each curve: n=1.
(c) Testing samples in different gray levels
(d) Experiment setups
(e) Relationship between gray levels and bending curvature. Sample size for each gray level: n=3
(f) Relationship between gray levels and responding speed. Sample size for each gray level: n=3
