back to top  1. The Sound of a Hug

The Sound of a Hug is an installation about an experience I had when I was young. My parents would take me to nursery school by motorcycle. On the way to school, I could hear a melody deep in my heart, while also hearing the sounds around me. This installation has a set of 3D-printed microswitches that respond when squeezed in a particular way. There are three parts to the mechanism that make three kinds of sounds: the melody of my memory, the sound of the motorcycle, and the sound of the trees swaying in the wind. When I hug my installation—just as when I hugged my parents on the motorcycle—I can hear the same melody and sounds once again.

PaperMech (aka FoldMecha) is a design system for the exploratory construction of mechanical papercraft. It enables users to design movements with simple mechanisms by modifying parameters, download the parts and folding nets to build the mechanisms, and adapt them into their own creations. Our website (below) provides assembly instructions along with a gallery, where you will find a diverse array of expressive paper machines created by our workshop participants.

Bear Abouts is a research project into storytelling and tangible media. We have developed a digital and physical storytelling platform for children that gives kids the power to create and influence stories through making. We built a platform for Android devices in Unity 3D that uses touch points to connect with a package of physical components. It combines paper pages with animations and events on screen to make tactile storytelling experiences for children.

tactoRing is a novel smart ring that provides rich, yet subtle, discrete haptic feedback based on the high tactile resolution of the finger skin. tactoRing excites the skin by dragging a small movable actuator around the finger, directly in contact with the skin. This allows users to perceive tactile feedback in the form of motion applied to specific locations around the finger, with different speeds and directions. By controlling the ring through a separate device such as a mobile phone or a car navigation system, the ring can be used, for example, to convey street directions and caller IDs using motion.
