    • A video headset is worn comfortably on the head of a user, supported by a pair of spaced apart straps extending over the top of the head and across the lower back of the head. The rear strap may be counterweighted. A pair of headphone type speakers are supported on pivoted arms from a frame of the headset, so as to be swingably adjustable to accommodate ear position. In a preferred embodiment, a pair of LCD video displays are positioned above the level of the user's eyes, each with a beam splitter positioned in front of the eyes to reflect a portion of the light from the video screens to the user. The partially transmissive beam splitters allow the user to see through to the ambient scene beyond, increasing the comfort of the user in viewing the video. A transparent shield preferably is positioned forward of the video optics, with an adjustment under the control of the user for controlling the brightness of the ambient light. The video screens and optics preferably set the user's convergence angle at about eight feet, for optimum comfort.
    • 视频耳机舒适地佩戴在用户的头部上,由一对间隔开的带支撑,该带在头部的顶部和头部的后后延伸。 后排可以配重。 一对耳机型扬声器从耳机的框架支撑在枢转臂上,以便可摆动地调整以适应耳朵位置。 在优选实施例中,一对LCD视频显示器位于用户眼睛的水平面之上,每个具有位于眼睛前方的分束器,以将来自视频屏幕的光的一部分反射到用户。 部分透射的分束器允许用户透视到环境场景之外,增加用户观看视频的舒适性。 透明屏蔽优选地位于视频光学器件的前方,在用户的控制下进行调节以控制环境光的亮度。 视频屏幕和光学器件优选地将用户的会聚角度设置在约八英尺处,以获得最佳的舒适度。
