Blindness affects millions of people around the world, and is expected to become increasingly prevalent in the years to come. For some blind individuals, a promising solution to restore a form of vision are cortical visual prostheses, which convert camera input to electrical stimulation of the cortex to bypass part of…

Walking support systems are essential for blind people. In this study, the presentation of phosphene position is focused on as a method to detect obstacles for blind people. When the phosphene is used in a walking support system, it is necessary to accurately present the phosphene in at least three directions of the…

We utilized the open-source Unity toolbox BionicVisionXR (https: //github.com/bionicvisionlab/BionicVisionXR), to simulate prosthetic vision within an immersive VR environment. Participants viewed stimuli through an HTC VIVE Pro Eye head-mounted display, with phosphene appearance modeled using psychophysically…

raster pattern for retinal implants Authors: ['Justin Kasowski' 'Michael Beyeler'] Approach: Sighted participants completed letter recognition and motion discrimination tasks under four raster patterns (horizontal, vertical, checkerboard, and random) using an immersive SPV system. The simulations employed…

Prosthetic vision based on phosphenes is a promising way to provide visual perception to some blind people. However, phosphenic images are very limited in terms of spatial resolution (e.g.: 32 x 32 phosphene array) and luminance levels (e.g.: 8 gray levels), which results in the subject receiving very limited…

'Xuyue Wang' 'Ping Zhou'] Effectively utilizing deep red to near-infrared (DR-NIR) phosphors to achieve the optimal performance of NIR phosphor-converted white LEDs (DR-NIR pc-wLEDs) is currently a research hotspot. In this study, an optical model of DR-NIR pc-wLEDs with virtual multilayer fluorescent films was…

Increasing phosphor layer thickness and concentration can enhance the lumen flux of white LED (W-LED). In this work, we found that increasing the phosphor layer thickness and concentration can increase its temperature, and there is also a maximum thickness and concentration beyond which their increase will not lead to…

Electrochemiluminescence (ECL) is a vital analytical technique widely used in immunosensing and emerging applica-tions in biological imaging. Traditional ECL simulations rely on finite element methods, which provide valuable insights into reaction dynamics and spatial distribution of species. However, such methods are…

We present MUFASA (Multi-Protocol Unified Fluorescence-based Advanced Simulation Algorithm), a physically grounded, continuous-time simulator for super-resolution fluorescence microscopy. By modeling fluorophore dynamics using continuous-time Markov chains, MUFASA’s simulation features yield realistic photon emission…
