ステレオ明瞳孔法を用いたEye－Tracking液晶ペンタブレットの開発

摘要

Intuitive I/O interface of PCs and PDAs, such as pen display and touch panel, has come into wide use recently. However, it is necessary to analyze and clarify human essential interaction via such interface. In this study, we developed an eye-tracking pen display based on the stereo bright pupil technique for the analysis by synthesis of the timing control of human interaction via pen display. First, the "bright pupil camera" was developed by examining the arrangement of cameras and LEDs. Next, the gaze estimation method was proposed for the bright pupil camera, which enables one point calibration. Then, the prototype of the eye-tracking pen display was developed. The accuracy of the system was about 0.9 degrees in average, which is enough for human interaction analysis.%情報爆発時代と言われるように、人類によって創出される情報量は近年爆発的に増大している［1］。今後、高機能化・多機能化する情報機器や情報サービスを誰もが安心して使えるように、情報システムと人が自然にコミュニケーション・インタラクションできる新たなヒューマンコミュニケーション基盤が求められている［2］。
