我们提出了一个组合的头眼跟踪系统，适用于在自然活动过程中的自由头部运动。该系统提供了一个集成的头部和眼睛的位置测量，同时允许大范围的头部运动（可耐受约1.8 m的头部平移），通过该系统测量头部运动的六个自由度和眼睛运动的两个自由度。该系统被设计用于评价前庭眼反射（VOR），VOR产生补偿性眼球运动，以便在头部的线性或旋转运动期间稳定凝视。VOR的当前临床和基础研究评估已经使用了有限范围的头部运动，主要是低频、偏航旋转，一个集成的眼头跟踪系统，如这里提出的一个允许VOR响应的线性和角头部运动进行研究，在一个更生理相关的方式。集成的头部和眼睛跟踪系统在评估线性和角运动的前庭反应的效用的两个例子。
We present a combined head-eye tracking system suitable for use with free head movement during natural activities. This system provides an integrated head and eye position measurement while allowing for a large range of head movement (approx 1.8 m of head translation is tolerated), Six degrees of freedom of head motion and two degrees of freedom of eye motion are measured by the system, The system was designed to be useful for the evaluation of the vestibule-ocular reflex (VOR), The VOR generates compensatory eye movements in order to stabilize gaze during linear or rotational motion of the head, Current clinical and basic research evaluation of the VOR has used a restricted range of head motion, mainly low-frequency, yaw rotation, An integrated eye-head tracking system such as the one presented here allows the VOR response to linear and angular head motion to be studied in a more physiologically relevant manner. Two examples of the utility of the integrated head and eye tracking system in evaluating the vestibular response to linear and angular motion are presented.
