Mobility Enhancement Using Simulated Artificial Human Vision
The electrical stimulation of appropriate components of the human visual system can result in the perception of blobs of light (or phosphenes) in totally blind patients. By stimulating an array of closely aligned electrodes it is possible for a patient to perceive very low-resolution images from spatially aligned phosphenes. Using this approach, a number of international research groups are wor...
متن کاملMobility aid for blind figure skaters
This work is developed within the scope of rehabilitation technology to enable blind and visually impaired persons read non-Braille material commonly available in digital form to normal-vision readers. This approach, therefore, tries to broaden the reaching capacity for these persons and, thus, allow for better inclusion in social, work, educative and even leisure activities. Specifically, it i...
متن کاملToward a Mobility Aid for the Blind
The development of mobility aids for the blind is a challenging task that has a number of potential solutions. Direct electrical stimulation of the visual cortex has been used to generate ‘phosphenes’ (perceived as flashes of light) that can, with training, be interpreted as low resolution images. A second approach is to use a grid of tactile stimulators to represent an array of pixels. Thirdly...
متن کاملThe Smart Vision Local Navigation Aid for Blind and Visually Impaired Persons
The SmartVision prototype is a small, cheap and easily wearable navigation aid for blind and visually impaired persons. Its functionality addresses global navigation for guiding the user to some destiny, and local navigation for negotiating paths, sidewalks and corridors, with avoidance of static as well as moving obstacles. Local navigation applies to both inand outdoor situations. In this art...
متن کاملMultisensory virtual environment for supporting blind persons’ acquisition of spatial cognitive mapping, orientation, and mobility skills
Mental mapping of spaces, and of the possible paths for navigating these spaces, is essential for the development of efficient orientation and mobility skills. Most of the information required for this mental mapping is gathered through the visual channel. Blind people lack this crucial information and in consequence face great difficulties (a) in generating efficient mental maps of spaces, and...
