科学领域:

  • 人与计算机的交互
  • 辅助技术 辅助技术 辅助技术
  • 虚拟现实 虚拟现实 虚拟现实

背景情况:

  • 视力障碍对中年和老年人的移动性构成挑战.
  • 传统的移动辅助工具有其局限性,这推动了人们对电子旅行辅助工具 (ETA) 的兴趣.
  • 目前的ETA通常缺乏经验证据和现实的测试环境,重点是单一感官增强.

研究的目的:

  • 建立一个新的虚拟现实 (VR) 环境,用于在复杂的城市环境中测试模拟视力障碍 (VI) 的ETA.
  • 评估触觉和音频反 (单独和组合) 对导航性能,运动行为和感知的影响.
  • 通过解决研究缺陷,促进对VI患者的辅助技术 (AT) 的发展.

主要方法:

  • 开发了一个VR地铁站环境,模拟VI患者常见的导航挑战.
  • 测试了一种多传感器,AT集成的VR平台,72名健康参与者在模拟VI.
  • 使用完成时间和轨迹平滑度等指标评估导航性能,具有四个反条件:触觉,音频,组合和没有.

主要成果:

  • 触觉反显著减少了碰撞和头部位置的变化.
  • 音频反增强了轨迹的平滑性,并减轻了单纯通过触觉反引起的轨迹长度增加.
  • 虽然参与者发现VR具有吸引力,但大多数人更喜欢单个反方式而不是组合方式.

结论:

  • 以用户为中心的设计和在生态有效的环境中分阶段测试对于VI的AT开发至关重要.
  • 开发的多感官虚拟现实系统提供了一种整体方法,以提高空间意识并促进更安全的移动.
  • 这种VR系统在医疗治疗,培训和康复方面具有潜在的应用,旨在改善VI患者的独立性和生活质量.
