In this work, we study the enhancement of simulated prosthetic reading performance through "active photonic sensing" in normally sighted subjects. Three sensing paradigms were implemented: active sensing, in which the subject actively scanned the presented words using the computer mouse, with an option to control text size; passive scanning produced by software-initiated horizontal movements of words; and no scanning. Our findings reveal a 30% increase in word recognition rate with active scanning as compared to no or passive scanning and up to 14-fold increase with zooming. These results highlight the importance of a patient interactive interface and shed light on techniques that can greatly enhance prosthetic vision quality.
在这项研究中,我们研究了通过“主动光子传感”来提高正常视力受试者的模拟假体阅读性能。实施了三种传感模式:主动传感,即受试者使用电脑鼠标主动扫描呈现的单词,并可选择控制文本大小;由软件启动的单词水平移动产生的被动扫描;以及不进行扫描。我们的研究结果表明,与不扫描或被动扫描相比,主动扫描的单词识别率提高了30%,放大时提高了多达14倍。这些结果突出了患者交互界面的重要性,并为可大幅提高假体视觉质量的技术提供了启示。
