Methods and devices for improving visual perception in challenging vision environments and for some with low vision conditions (including age related macular degeneration, AMD) are disclosed. A plurality of frequently co-pathological conditions that together make undistorted, clear and bright vision challenging are dealt with by managing the nature, amounts and patterns of light reaching the eyes while managing the sensitivity and dynamic ranges of the eyes. For example, the sensitivity of chromophore response to particular wavelengths and the instant status of the visual transduction system are, in some embodiments, measured, monitored and managed.

The disclosed head-mounted display assemblies may include a first eyecup and a second eyecup that are configured for positioning in front of intended locations of a user's eyes. The first eyecup and the second eyecup may be movable relative to each other to adjust for an interpupillary distance of the user's eyes. The head-mounted display assemblies may also include a single near-eye display screen configured for displaying an image to the user through the first eyecup and the second eyecup. A flexible shroud may be positioned to provide a seal between a first interior volume of the first eyecup, a second interior volume of the second eyecup, and the single near-eye display screen. Various other methods, devices, systems, and assemblies are also disclosed.

An interactive method using a floating image display and a system thereof are provided. The method is performed in the display apparatus. The display apparatus links to a computer system that executes a driver for establishing a communication interface there-between. In the method, the display apparatus receives image data from the computer system and floating image data can be obtained therefrom. The floating image display apparatus displays a floating image via a display panel after a conversion process. After that, a user can manipulate directly on the floating image by gesture. A procedure running in the display apparatus can determine an interactive instruction according to variations of three-dimensional coordinates. When the interactive instruction is transmitted to the computer system, a new image data is formed in response to the interactive instruction. The display apparatus then displays a new floating image after receiving new data.

A light field volumetric device for displaying images or flows of fluctuating and stereoscopic 3D images. The device includes emitting means and a reflection system. The reflection system has first and second concave reflecting means. The first concave reflecting means comprises an aperture. An image generated by the device is perceivable by an observer, located at a distance with respect to the second concave reflecting means, when the observer looks towards the second concave reflecting means. A calculation unit is associated with the device and is configured to calculate the distance.
