Objective. Visual prostheses are designed to restore partial functional vision in patients with total vision loss. Retinal visual prostheses provide limited capabilities as a result of low resolution, limited field of view and poor dynamic range. Understanding the influence of these parameters in the perception results can guide prostheses research and design. Approach. In this work, we evaluate the influence of field of view with respect to spatial resolution in visual prostheses, measuring the accuracy and response time in a search and recognition task. Twenty-four normally sighted participants were asked to find and recognize usual objects, such as furniture and home appliance in indoor room scenes. For the experiment, we use a new simulated prosthetic vision system that allows simple and effective experimentation. Our system uses a virtual-reality environment based on panoramic scenes. The simulator employs a head-mounted display which allows users to feel imm...

视野在视觉假肢设计中的影响：使用 VR 系统进行分析。

客观的。视觉假体旨在恢复完全视力丧失的患者的部分功能性视力。由于分辨率低、视野有限和动态范围差，视网膜视觉假体提供的功能有限。了解这些参数对感知结果的影响可以指导假肢的研究和设计。方法。在这项工作中，我们评估视野对视觉假体空间分辨率的影响，测量搜索和识别任务中的准确性和响应时间。24 名视力正常的参与者被要求在室内场景中找到并识别常见的物体，例如家具和家用电器。对于实验，我们使用了一种新的模拟假肢视觉系统，可以进行简单有效的实验。我们的系统使用基于全景场景的虚拟现实环境。该模拟器采用了头戴式显示器，让用户能够感受到即时...
