Judgments Under Simulated Visual Space Conditions
1987 SUMMARY Thirty-jive volunteers responded when they first perceived an increase in apparent size o f a collimated, two-dimensional image of an Orbiter vehicle. The test variables of interest included the presence o f afixed angular reticle within the field of view (FOV); three initial Orbiter distances; three constant Orbiter approach velocities corresponding to 1.6, 0.8, and 0.4% of the in...
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 کاملReading 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 کاملSimulated Firefighting Task Performance and Physiology Under Very Hot Conditions
PURPOSE To assess the impact of very hot (45°C) conditions on the performance of, and physiological responses to, a simulated firefighting manual-handling task compared to the same work in a temperate environment (18°C). METHODS Ten male volunteer firefighters performed a 3-h protocol in both 18°C (CON) and 45°C (VH). Participants intermittently performed 12 × 1-min bouts of raking, 6 × 8-min...
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...
