Urushi Circuits: 漆回路を用いたタッチインタフェース

概要: 漆は絶縁性を持つ天然の樹脂塗料である.基盤や電子回路用の塗料として使用することによって,美しい外観と手触りを持つ回路を構成することができる.また,漆を絶縁層として用いることにより,多層電子回路を構築することも可能となる.本研究では,多層漆回路を用いてタッチインタフェースを構築する手法を検討する.はじめに,タッチ電極を 持つ2層構造の漆回路を作製した.続いて,見た目の美しさを改善するために,すべてのタッチ電極が最上層に配置され,配線が最下層に隠されている漆回路を作製した.更に,タッチインタフェースの拡張として,2次元タッチセンシングを実現するために格子状に配置されたタッチ電極を作製した.
Abstract: Urushi (Japanese lacquer) is a natural resin paint with electrical insulating capability. By using it as a base material and coating material for electronic circuits, it is possible to construct a circuit with an elegant appearance and feel. It is also possible to build a multilayered electronic circuit by using urushi as insulation layers. In this study, we investigate techniques to construct touch interfaces using a multilayered electronic circuit (urushi circuit). At first, we fabricated an urushi circuit with a touch electrode consisting of two layers. To improve its appearance, we fabricated urushi circuits in which all touch electrodes are arranged on the top layer and all wires are hidden in the bottom layer. Moreover, as an extension of the touch interface, we built a grid of touch electrodes that realizes two-dimensional touch sensing.

Tesla Blocks: 磁気に基づくブロックシステム

Abstract: We present a block system with magnetism-based structure recognition. Our system allows users to create 3D models using intuitive operation of building blocks. Each block of our system has a simple structure with a permanent magnet. Our system recognizes the structure of blocks by using hardware with multiple magnetic sensors.



Capacitive Blocks: 静電容量に基づくブロックシステム

Abstract: Capacitive Blocks is a block-shaped tangible user interface that connects the physical space to the virtual space, allowing users to build 3D models in the virtual space by handling tangible blocks. The system counts the number of stacked blocks by measuring the capacitance with a capacitance meter; the system recognizes the structure of stacked blocks arranged in a grid using the capacitance meter and generates 3D models. In this study, we improved the stability of Capacitive Blocks, presented by Yoshida et al. at UIST ’15, by revising the block design: each block of the new system has a built-in capacitor. To evaluate the improvement, we conducted an experiment. The result showed a counting accuracy of 96.5%.
