| Outline of Final Research Achievements |
We have developed video-oculograhy (HI-VOG) using freeware image analysis software ImageJ. HI-VOG requires offline analysis to be performed after recording, manual pupil recognition setting is required. Therefore, we developed an improved real-time three-dimensional analysis video-oculography (VOG). It enables recording and filing, automated pupil recognition and analysis, real-time nystagmus display, detailed analysis, and result report. An infrared flunzel was created using a high-speed camera and an accelerometer. A light weight, high image quality, and high speed are possible. The obtained acceleration and angular velocity are taken into a PC using a small 9-axis sensor device mounted with a 3-axis acceleration sensor, 3-axis angular velocity sensor, and 3-axis geomagnetic sensor, and the head position direction and velocity are analyzed. Analysis was performed in synchronization with the head position information.

| Academic Significance and Societal Importance of the Research Achievements |
開発した軽量高画質・高速赤外線CCDを用い、日常臨床および臨床研究において、リアルタイムで詳細な眼振、眼球運動を記録することが可能になる。頭位モニタリングセンサは，めまい患者の日常や睡眠頭位の解析など，めまい入院患者の頭位の解析などの研究にも応用できる。頭位，頭位変換眼振検査および頭位治療にブレークスルーをもたらすと考える。
