Optimization of Visual Information Presentation for Visual Prosthesis [PDF]
International Journal of Biomedical Imaging, 2018 Visual prosthesis applying electrical stimulation to restore visual function for the blind has promising prospects. However, due to the low resolution, limited visual field, and the low dynamic range of the visual perception, huge loss of information ...

Visual Prosthesis: Interfacing Stimulating Electrodes with Retinal Neurons to Restore Vision [PDF]
Frontiers in Neuroscience, 2017 The bypassing of degenerated photoreceptors using retinal neurostimulators is helping the blind to recover functional vision. Researchers are investigating new ways to improve visual percepts elicited by these means as the vision produced by these early ...

Reading visual Braille with a retinal prosthesis [PDF]
Frontiers in Neuroscience, 2012 Retinal prostheses, which restore partial vision to patients blinded by outer retinal degeneration, are currently in clinical trial. The Argus II retinal prosthesis system was recently awarded CE approval for commercial use in Europe.

Perception, 2008 There are more than forty million blind individuals in the world whose plight would be greatly ameliorated by creating a visual prosthesis. We begin by outlining the basic operational characteristics of the visual system, as this knowledge is essential for producing a prosthetic device based on electrical stimulation through arrays of implanted ...

Human-prosthesis cooperation: combining adaptive prosthesis control with visual feedback guided gait
Journal of NeuroEngineering and Rehabilitation, 2022 Background Personalizing prosthesis control is often structured as human-in-the-loop optimization. However, gait performance is influenced by both human control and intelligent prosthesis control.

Visual and Non-Visual Navigation in Blind Patients with a Retinal Prosthesis. [PDF]
PLoS ONE, 2015 Human adults with normal vision can combine visual landmark and non-visual self-motion cues to improve their navigational precision. Here we asked whether blind individuals treated with a retinal prosthesis could also benefit from using the resultant new

Clinical Progress and Optimization of Information Processing in Artificial Visual Prostheses
Sensors, 2022 Visual prostheses, used to assist in restoring functional vision to the visually impaired, convert captured external images into corresponding electrical stimulation patterns that are stimulated by implanted microelectrodes to induce phosphenes and ...
