Abstract: Methods and systems are disclosed relating to a lens system that allows for simultaneous focus of near and far-away images with one pair of glasses, heads-up-displays (HUDs), and the like, without the need to move the user's eyes. This lens system may be used in a HUD application, for example, where the user may focus on a display lens that may be approximately one inch from the eye to view computer-generated information such as altitude, temperature, directions, and the like, and simultaneously view the individual's surroundings. The lens system may include a liquid lens that when modulated may vary from a near-focus state to a far-focus state rapidly by using an electrowetting or piezoelectric hydraulic actuator. This variable rate lens may be multiplexed at a rate that allows both near and far-away images to appear in focus simultaneously through the advantageous use of a user's persistence of vision.

Abstract: In certain embodiments, a head-mounted display may include one or more displays for displaying images. A left and right movable disk may be placed respectively between the left and right eyes of a user and the one or more displays. The user may wear the HMD, and may adjust the spacing between the left and right disks while viewing the computer-displayed image or images through holes in the plastic discs. For example, the HMD may display a stereo colored bulls eye pattern, of which the user can only see a portion because their vision is restricted to on-axis viewing by the discs. The computer may instruct the user to move the HMD disks until the user can only see the color in the center of the bulls eye. In certain embodiments, by performing the foregoing adjustment, the eye may be oriented on the proper optical axis to look through an optimal location of a lens.
Abstract translation: 在某些实施例中，头戴式显示器可以包括用于显示图像的一个或多个显示器。 左右可动盘可以分别放置在用户的左眼和右眼之间以及一个或多个显示器上。 用户可以佩戴HMD，并且可以通过在塑料盘中的孔观察计算机显示的图像或图像来调整左右盘之间的间距。 例如，HMD可以显示立体彩色多眼眼图，其中用户只能看到一部分，因为它们的视觉被限制在盘上的轴上观看。 计算机可以指示用户移动HMD盘，直到用户只能看到公牛中心的颜色。 在某些实施例中，通过执行前述调整，眼睛可以在适当的光轴上定向以透视透镜的最佳位置。

Abstract: Methods and systems relating to compensation for discrepancies in an image that may be captured with a moving camera or a moving head. The visual artifacts in the visual field may be reduced or eliminated by monitoring head and camera movements for a Heads Up Display (HUD) application, and feeding back the movement data to a compensation circuit to eliminate or reduce the visual artifacts such as judder effect, as the head and the camera move relative to the objects that the camera may be capturing. The duty cycle of one or more pixels and/or one or more groups of pixels of the display may be varied at different rates for different head and camera movement speeds. The faster the camera or head moves the shorter the duty cycle that may be applied to the display so that the image has low persistence.
Abstract translation: 与可以用移动的相机或移动头捕获的图像中的差异的补偿相关的方法和系统。 可以通过监视头部显示（HUD）应用的头部和相机移动来减少或消除视野中的视觉伪影，并且将移动数据反馈到补偿电路以消除或减少诸如抖动效应的视觉伪影， 因为头部和相机相对于相机可能捕获的物体移动。 对于不同的头部和相机移动速度，显示器的一个或多个像素和/或一组或多组像素的占空比可以以不同的速率变化。 相机或头部移动越快，可能施加到显示器的占空比越短，因此图像持续时间不变。
