“…Goldring et al [2006] has adapted a display with lenses to focus the image on the center of the eye lens improving readability. In the same way, Liu and Hua [2009], and Rolland et al [2000] have introduced dynamic lenses that change the plane of focus and a stack of planes that are selectively illuminated to create volumetric head-mounted displays. These techniques, however, require moving parts and do not account for non-symmetric aberrations, such as astigmatism, higher-order aberrations, and cataracts.…”

Tailored displays to compensate for visual aberrations

We introduce tailored displays that enhance visual acuity by decomposing virtual objects and placing the resulting anisotropic pieces into the subject's focal range. The goal is to free the viewer from needing wearable optical corrections when looking at displays. Our tailoring process uses aberration and scattering maps to account for refractive errors and cataracts. It splits an object's light field into multiple instances that are each in-focus for a given eye subaperture. Their integration onto the retina leads to a quality improvement of perceived images when observing the display with naked eyes. The use of multiple depths to render each point of focus on the retina creates multi-focus, multi-depth displays. User evaluations and validation with modified camera optics are performed. We propose tailored displays for daily tasks where using eyeglasses are unfeasible or inconvenient (e.g., on head-mounted displays, ereaders, as well as for games); when a multi-focus function is required but undoable (e.g., driving for farsighted individuals, checking a portable device while doing physical activities); or for correcting the visual distortions produced by high-order aberrations that eyeglasses are not able to.

“…These could be used for our purposes to some extent. Liu and Hua [2009] have shown a liquid lens based solution to change the plane of focus inside a head mounted display (HMD). Rolland et al [2000] showed a multiplanar volumetric display based on a stack of laminated planes that are selectively illuminated inside a HMD.…”

We introduce an interactive, portable, and inexpensive solution for estimating refractive errors in the human eye. While expensive optical devices for automatic estimation of refractive correction exist, our goal is to greatly simplify the mechanism by putting the human subject in the loop. Our solution is based on a high-resolution programmable display and combines inexpensive optical elements, interactive GUI, and computational reconstruction. The key idea is to interface a lenticular view-dependent display with the human eye in close range -a few millimeters apart. Via this platform, we create a new range of interactivity that is extremely sensitive to parameters of the human eye, like refractive errors, focal range, focusing speed, lens opacity, etc. We propose several simple optical setups, verify their accuracy, precision, and validate them in a user study.

“…Things are getting worse when it is applied in augment reality or stereoscopic display, which limits the further development of HMDs. Many approaches have been proposed to solve this problem by generating dual or multiple focal planes in HMD, such as spatial-multiplexed [10] [11] and time-multiplexed methods [12] [13]. However, the complexity of these systems will be increased by employing multiple micro-displays or half mirrors in the spatial-multiplexed methods or by the active elements in the time-multiplexed methods.…”

A light field head-mounted display (LF-HMD) using a micro structure array (MSA, lens array or pinhole array) is proposed to realize true three dimensional (3D) display. Dense light field of 3D scene is generated inside the exit pupil of HMD and the viewer can obtain correct depth. This method not only solves the huge data problem in true 3D displays, but also alleviates the visual fatigue in traditional HMDs. Design considerations of LF-HMD system have been analyzed in detail and an optical see-through LF-HMD has been designed using a wedge-shaped freeform prism cemented with a freeform lens and a pinhole array. The experimental result shows that the proposed method is capable of generating a dense light field to obtain a corrected perception of depth.
