Reading pixelized paragraphs of Chinese characters using simulated prosthetic vision.
PURPOSE Visual prostheses offer a possibility of restoring useful reading ability to the blind. The psychophysics of simulating reading with a prosthesis using pixelized text has attracted attention recently. This study was an examination of the reading accuracy and efficiency of pixelized Chinese paragraphs after different parameters were altered. METHODS Forty native Chinese speakers with n...
متن کاملFacial recognition using simulated prosthetic pixelized vision.
PURPOSE To evaluate a model of simulated pixelized prosthetic vision using noncontiguous circular phosphenes, to test the effects of phosphene and grid parameters on facial recognition. METHODS A video headset was used to view a reference set of four faces, followed by a partially averted image of one of those faces viewed through a square pixelizing grid that contained 10x10 to 32x32 dots se...
متن کاملRepeatability of reading ability indices in subjects with impaired vision.
PURPOSE Reading speed and acuity measurements are important means of evaluating reading performance in subjects with impaired vision. The MNREAD charts are gradually becoming a popular means of measuring reading ability in low-vision clinics; yet, to date there are no standards of reliability for the visually impaired population. The present study was conducted to determine the coefficients of ...
متن کاملEvaluation of Contrast Sensitivity, Chromatic Vision, and Reading Ability in Patients with Primary Open Angle Glaucoma
Purpose. To compare contrast sensitivity, acquired color vision deficiency, and reading ability in patients with glaucoma at different stages of the disease and to establish correlations between visual field parameters and visual function scores. Methods. This prospective cross-sectional study included 121 glaucoma patients. Subjects with a diagnosis of chronic open angle glaucoma were recruite...
متن کاملRecognition of a Virtual Scene via Simulated Prosthetic Vision
In order to effectively aid the blind with optimal low-resolution vision and visual recovery training, pathfinding and recognition tests were performed using a simulated visual prosthetic scene. Simple and complex virtual scenes were built using 3DMAX and Unity, and pixelated to three different resolutions (32 × 32, 64 × 64, and 128 × 128) for real-time pixel processing. Twenty subjects were re...
