【摘要】 在工业生产的某些条件下,操作者必须采取仰视或俯视的姿势来控制机器或其它机械设备。这样的观察姿势往往给深度视觉造成影响——使深度判断的阈值增加。在本研究中采用了一种立体应用电视,被观察对象不论处于什么位置都可以三维地呈现于屏幕上,于是操作者能以正常的观察姿势来控制该对象。本实验结果表明应用这种类型的电视可以补偿在仰视或俯视观察姿势下对深度视觉造成的不利影响。更多还原

【Abstract】 Under some conditions in industry the operator should take an upward ordownward observation position for controlling the machine or other mechanicaldevices.This kind of observation position usually exerts influence upon theaccuracy of depth vision—increasing the threshold in depth judgment.In thisstudy a closed stereo T.V.was used on the screen of which the observingobject could be displayed in three dimensions under any position,so theoperator was able to control the object under a normal observationposition.The result of this experiment demonstrated the benefical effect inusing this kind of T.V.to compensate the disorder in depth vision under theinfluence of upward and downward observation position.更多还原
