Experiments have been conducted on human subjects to assess the efficiency with which a helmet-mounted sighting system can be used to locate and track target sources in the horizontal plane. In the first experimental condition, in which the sight was aligned with discrete stationary target sources, the latency between target presentation and final target location was in the 2-4 s range, dependent upon the amplitude of target offset and the rate of head movement. In the second condition, subjects were instructed to track a sinusoidally oscillating visual image with the sight. Tracking performance was found to be impaired when the frequency of oscillation was increased beyond 0.8-1.0 Hz. Recording of eye movement during both experimental conditions indicated that the impairment of performance could, in part, be attributed to involuntary eye movements consequent upon stimulation of the vestibulo-ocular reflex by the head turning movements.
已经在人类受试者身上进行了实验，以评估头盔式瞄准系统在水平面上用于定位和跟踪目标源的效率。在第一种实验条件下，即瞄准器与离散的静止目标源对齐时，目标呈现与最终目标定位之间的延迟在2 - 4秒范围内，这取决于目标偏移的幅度和头部移动的速度。在第二种条件下，受试者被要求用瞄准器跟踪正弦振荡的视觉图像。当振荡频率增加到超过0.8 - 1.0赫兹时，发现跟踪性能会受到损害。在两种实验条件下对眼球运动的记录表明，性能受损部分可归因于头部转动运动刺激前庭眼反射后产生的不自主眼球运动。
