The development and evaluation of autofocal glasses require robust and efficient tools for assessing their performance in various real-world scenarios. This study presents a novel virtual reality (VR) simulation tool designed to evaluate the control algorithms of autofocal glasses. The tool incorporates a matching task involving Landolt rings and Sloan letters presented on different screens at varying distances and a NASA Task Load Index (TLX) questionnaire to assess participants’ subjective workload and convenience. By employing this experimental design, we aimed to gain insights into the effectiveness and efficiency of the evaluated control algorithms for autofocals within our VR-based simulation tool. Our results indicate that the developed VR simulation tool provides a valuable platform for assessing the performance of autofocal glasses in a controlled environment, ultimately contributing to the development of more efficient and user-friendly autofocal glasses.
