Abstract

Integrating biofeedback technology, such as real-time eye-tracking, has revolutionized the landscape of virtual reality (VR) rehabilitation games, offering new opportunities for personalized therapy. Motivated to increase patient focus during rehabilitation, the Focus-Driven Augmented Feedback (FDAF) system was developed to enhance focus and maintain engagement during upper limb VR rehabilitation. This novel approach dynamically adjusts augmented visual feedback based on a patient's gaze, creating a personalised rehabilitation experience tailored to individual needs. This research aims to develop and comprehensively evaluate the FDAF system to enhance patient focus and maintain engagement in VR rehabilitation environments. The methodology involved three experimental studies, which tested varying levels of augmented feedback with 71 healthy participants and 17 patients requiring upper limb rehabilitation. The results demonstrated that a 30% augmented level was optimal for healthy participants, while a 20% was most effective for patients, ensuring sustained engagement without inducing discomfort. The research's findings highlight the potential of eye-tracking technology to dynamically customise feedback in VR rehabilitation, leading to more effective therapy and improved patient outcomes. This research contributes significant advancements in developing personalised VR rehabilitation techniques, offering valuable insights for future therapeutic applications.
焦点驱动的增强反馈:在上肢虚拟现实康复中增强焦点和保持参与。
整合生物反馈技术,如实时眼动追踪,已经彻底改变了虚拟现实(VR)康复游戏的格局,为个性化治疗提供了新的机会。为了提高患者在康复过程中的注意力,开发了焦点驱动增强反馈(focus - driven Augmented Feedback, FDAF)系统,以增强上肢VR康复过程中的注意力并保持参与。这种新颖的方法根据患者的目光动态调整增强的视觉反馈,创造出个性化的康复体验,以满足个人需求。本研究旨在开发和全面评估FDAF系统,以增强患者的注意力并保持VR康复环境中的参与度。该方法涉及三项实验研究,对71名健康参与者和17名需要上肢康复的患者进行了不同程度的增强反馈测试。结果表明,30%的增强水平对健康参与者来说是最佳的,而20%的增强水平对患者来说是最有效的,确保持续参与而不会引起不适。该研究结果强调了眼动追踪技术在VR康复中动态定制反馈的潜力,从而带来更有效的治疗并改善患者的预后。这项研究为个性化VR康复技术的发展做出了重大贡献,为未来的治疗应用提供了有价值的见解。
