视觉诱发的自身运动感知称为矢量，是决定虚拟现实存在的生理和心理指标的重要因素。我们利用视觉广域图像构建了身体摇摆测量系统，研究了不同种类的摇摆、摇摆方向、摇摆频率和图像摇摆角度对身体摇摆的影响。发现当垂直图像滚动越大时，身体摇摆也越大，图像摇摆与身体摇摆之间的相关性变为90°相位图像摇摆频率高于 0 3 Hz 时延迟
Visually induced perception of self motion, called vection, is an important element to decide physiological and psychological index of presence of virtual reality We constructed a measurement system of body sway by using visual wide field images and studied the influence of the different kinds of sway, sway direction, sway frequency, and the sway angle of images for body sway We found out that the body sway becomes larger when vertical image rolls larger, and the the correlation between image sway and body sway become 90° phase delay when the sway frequency of the image is higher than 0 3 Hz
