摘要
为增大头盔显示器双目显示的总视域而又不降低图像分辨率,选用了双视觉的局部重叠视域。设计局部重叠显示时,需涉及两个至关重要的问题,即双目重叠范围及其结构或分布。分析双视性能、视觉灵敏度、眼球运动及人眼解剖参数等视觉处理特性,给双目重叠范围至少为40°的光学发散结构优异性提供了论据。
To increase the total field of view of HMD binocular displays without sacrificing image resolution,,partially overlapped field-of-view of the two oculars is used. Two important issues need to be addressed when designing partially-overlapped displays: the extent of the binocular overlap and the configuration or layout. Properties of visual processing such as binocularity,visual sensitivity, and eye movements, as well as anatomical data, provide evidence for the advantage of a divergent optical configuration with a binocular overlap of at least 40°.
