@book{oai:teapot.lib.ocha.ac.jp:00003978, author = {椎尾, 一郎 and 山本, 吉伸}, month = {Dec}, note = {application/pdf, 図書, We have developed an augmented reality (AR) system called AirPen, that can be used for a casual communication tools for wearable computer users. The AirPen provides virtual drawing on the air, and sharing them among users. Users of this system wear head mounted display (HMD) and draw messages using gyro-mouse. These messages are stored in a server computer and transmitted to wearable computers. Comparing to conventional AR systems, the AirPen system can be assembled using less precise components because the application focused on casual communication. To make the system handy, we have adapted inexpensive sensors, and consumer products. We also develop a simple and scalable positioning system called NaviGeta and ID-carpet, that detects user's position by reading RFID tags under carpets.}, publisher = {日本ソフトウェア科学会}, title = {コミュニケーションツールのための簡易型AR システム}, volume = {8}, year = {2000} }
