MultiJam: Fabricating Jamming User Interface using Multi-material 3D Printing

unseok Yang and Junichi Yamaoka

This study proposes a method of fabricating jamming user interfaces using multi-material 3D printing. Through customized fabrication software, users can decide the properties of components of the interface, such as the size/shape of beads. The software automatically renders a membrane and an inner complex of beads after users decide the properties, which simplifies the manufacturing process of the jamming interface. Moreover, 3D printing allows the interface to have a double structure consisting of multiple rooms functioning jamming independently, which realizes a richer haptic experience. Finally, this paper describes the manufacturing process of the jamming interface using 3D modeling software/3D printing. It demonstrates the merits of this method with several applications, such as the haptic device and the shape-changing controller.

TIEboard: Developing Kids Geometric Thinking through Tangible User Interface

Arooj Zaidi and Junichi Yamaoka

This research is based on the concept of computing being embedded within the tangible product that acts as both input and output device eliminating the need of traditional computers for any feedback or guidance.The idea is inspired from traditional geoboard that focuses on the age group from 5 to 8 years old. The main goal is to integrate technology seamlessly into physical manipulative and while using this product kids will be able to make complex shapes that offer kids with memorable learning experience.

What would people be like if they had scales? We would swim in the flow of the wind, use our scales to feel the world, exchange information with people, society, and nature, and emit light in response to the movement of our bodies. This work uses the conductive sequins as human scales to sense our breathing and body movement and signal the outside world with light.

The scales printed by 3d printer are made of conductive material, which can sense and transmit signals through the opening and closing of the scales to visualize the movement of our body and the affection by the environment. We can use the collision of scales to demonstrate the beauty of subtle body movements and decorate the body itself with body movements. It can also be used to visualize the shape of the wind we feel, decorate ourselves with nature’s power, and show our feelings to those around us.

It has a different tactility from our skin, hard but smooth; it protects us but does not resist the touch of others. We can use it to translate the touch of others into visualization, using our scales to tell each other the changes we have from other people’s touch. In a No-touch society, we try to avoid more intimate relationships while making us aware of the importance of human communication, and we will continue to find ways to prove our existence.
