9軸モーションセンサを併用した視線計測に関する研究

抄録

Humans perceive external environmental information using the five senses of sight, hearing, smell, taste, and touch. Since we perceive most of the information about the external environment based on visual information, measuring the line of sight is expected to clarify how humans relay visual information to their motor control system. However, it is not possible to evaluate the gaze position quantitatively unless the absolute coordinates of the line of sight are obtained. Therefore, in this study, we propose a new sensor fusion to estimate the absolute coordinates of the line of sight. The absolute coordinates of the line of sight were estimated by a Kalman filter using a portable 9-axis motion sensor and a gaze measurement system. We evaluated the accuracy for the absolute coordinates of the line of sight estimation in the experiment. This analytical method is anticipated for use in estimating the absolute coordinates of the line of sight in sports and healthcare applications.
