Head-Mounted Display Technology for Low-Vision Rehabilitation and Vision Enhancement

Applications of Augmented Vision Head-Mounted Systems in Vision Rehabilitation.

Vision loss typically affects either the wide peripheral vision (important for mobility), or central vision (important for seeing details). Traditional optical visual aids usually recover the lost visual function, but at a high cost for the remaining visual function. We have developed a novel concept of vision-multiplexing using augmented vision head-mounted display systems to address vision lo...

Head mounted video magnification devices for low vision rehabilitation: a comparison with existing technology.

Background Patients with low vision typically have reduced visual acuity and a significant loss of contrast sensitivity, often in combination with visual field loss. These impairments cause a number of disabilities including diYculty with reading, writing, recognising faces, watching television, orientation and mobility, and completing activities of daily living. In a recent large scale survey ...

Simple 1-D image enhancement for head-mounted low vision aid

High-contrast binary images (black and white without shades of gray) were demonstrated to improve face recognition performance by the visually impaired using static images (Peli et al., Invest Ophthalmol Vis Sci 1991;32:2337-2350). A binary head-mounted display device has now been adapted to present video in real time for testing as a low vision mobility aid (an electronic telescope). When used...

Rehabilitation Low Vision Algorithm

This article focuses on the rehabilitation of people with low vision, concretely on people with central or multiple loss of vision, and the use of new technological devices to assist them in their daily life by improving their ability to see in a better way the world around them, either virtual or real. This particular case refers to users with impaired vision, and the use of digital image proc...
