Abstract

ウェラブルコンピューティングやユビキタスコンピューティングにおいては,安定した電源供給方式,通信方式と高い空間配置自由度の確保は根本的な問題となる.すなわちウェアラブルおよびユビキタスコンピュータシステムでは,コンピュータやデバイスが空間に分散して存在し,各デバイスが電力を必要とするだけでなく相互通信も必要となる.この通信方式には無線通信と有線通信が考えられるが,無線通信では各デバイスへの長期的な安定した電力供給の方法が問題となり,また有線通信では電線の敷設にともなう空間配置の自由度の制約が問題となる.本稿では,ウェアラブル・ユビキタスコンピューティングシステムにおいて,これらの問題を解決できるネットワークシステムTextileNetを提案する.これは,衣服の表と裏にそれぞれ導電性布を用いて電極として用い,ここに1 個のバッテリから電力を供給する.そしてピンバッジのようにデバイスを衣服に差し込むことで実装が完了し,衣服表面電極に電源と信号を重畳することで,電源供給とデータ通信を行うことができる.本稿ではこのTextileNet システムの提案と実装,および評価を述べる.Numbers of devices distributed in wearable and ubiquitous environment requires stable power supply, communication channels, and flexibility of placement. There are two possible solutions for these problems; the wireless system and the wired system, but neither of them cannot satisfy these requirements perfectly. The wireless system has the problem of power supply method for devices, while the wired system has the restriction of physical placement for the complicated cables. In this paper, we propose the flexible network system, named as TextileNet, for wearable and ubiquitous computing systems that can solve these problems. TextileNet employs the wear whose both sides consist of low-resistance cloth as electrodes, and the power are supplied from a battery to the attached devices. The devices are attached on the wear by sticking the pin, and the devices can obtain both the power and communication channel by superposing of them on the conductive wear. This paper describes TextileNet system, as well as its implementation and evaluation.
