MotionSmith: A Sketch-Based Design System for Automata Making

We present MotionSmith, a sketch-based computational design system developed through participatory design (PD) with three experienced makers of mechanical crafts (automata). MotionSmith enables users to sketch and iteratively identify a desired motion, explore system-generated mechanisms to realize the motion, refine…

3D Printing Soap: Exploring New Biodegrdable Materials and Creative Possibilities

Soap is a colorful, DIY-friendly, and biodegradable material with potential beyond cleaning. This paper introduces a range of recipes for 3D-printable soap enhanced with additives that enable customization of color, scent, conductivity, and environmental responsiveness. To support fabrication, we designed a low-cost 3…

Tangible-MakeCode: Bridging Physical Coding Blocks with a Web-Based Programming Interface for Collaborative and Extensible Learning

Tangible programming engages children through hands-on and collaborative learning but often lacks integration with widely used programming platforms, which limits their extensibility and relevance in existing educational contexts. To address this, we propose Tangible-MakeCode (T-MC), a system that combines physical co…

SwellSense: Creating 2.5D interactions with micro-capsule paper

In this paper, we propose SwellSense, a fabrication technique to screen print stretchable circuits onto a special micro-capsule paper, creating localized swelling patterns with sensing capabilities. This simple technique will allow users to create a wide range of paper-based tactile interactive devices, which are most…

Functional Destruction: Utilizing sustainable materials' physical transiency for electronics applications

Today's electronics are manufactured to provide stable functionality and fixed physical forms optimized for reliable operation over long periods and repeated use. However, even when applications don't call for such robustness, the permanency of these electronics comes with environmental consequences. In this paper, we…

PITAS: Sensing and Actuating Embedded Robotic Sheet for Physical Information Communication

This work presents PITAS, a thin-sheet robotic material composed of a reversible phase transition actuating layer and a heating/sensing layer. The synthetic sheet material enables non-expert makers to create shape-changing devices that can locally or remotely convey physical information such as shape, color, texture a…

FlexHaptics: A Design Method for Passive Haptic Inputs Using Planar Compliant Structures

This paper presents FlexHaptics, a design method for creating custom haptic input interfaces. Our approach leverages planar compliant structures whose force-deformation relationship can be altered by adjusting the geometries. Embedded with such structures, a FlexHaptics module exerts a fine-tunable haptic effect (i.e.…

Shape-Haptics: Planar & Passive Force Feedback Mechanisms for Physical Interfaces

We present Shape-Haptics, an approach for designers to rapidly design and fabricate passive force feedback mechanisms for physical interfaces. Such mechanisms are used in everyday interfaces and tools, and they are challenging to design. Shape-Haptics abstracts and broadens the haptic expression of this class of force…
