Our objective in this paper is to review the application of feedback ideas in the area of
additive manufacturing. Both the application of feedback control to the 3D printing process …

The Special Issue “4D Printing: State-of-the-art, Recent Trends, and Applications” highlights
the significant impact of scientific advancements on practical and innovative applications. It …

To fabricate functional objects, designers create assemblies combining existing parts (eg,
mechanical hinges, electronic components) with custom-designed geometry (eg …

We introduce HERMITS, a modular interaction architecture for self-propelled Tangible User
Interfaces (TUIs) that incorporates physical add-ons, referred to as mechanical shells. The …

This paper presents ChainFORM: a linear, modular, actuated hardware system as a novel
type of shape changing interface. Using rich sensing and actuation capability, this modular …

We propose a hardware and software pipeline to fabricate flexible wearable sensors and
use them to capture deformations without line-of-sight. Our first contribution is a low-cost …

Exploring and manipulating complex virtual objects is challenging due to limitations of
conventional controllers and free-hand interaction techniques. We present the TanGi toolkit …

Due to their small surfaces, wearable devices make existing techniques for touch input very
challenging. This paper proposes deformation input on a tiny and soft surface as an input …

We present StrutModeling, a computationally enhanced construction kit that enables users
without a 3D modeling background to prototype 3D models by assembling struts and hub …

A tangible user interface or TUI connects physical objects and digital interfaces. It is more
interactive and interesting for users than a classic graphic user interface. This article …
