科学领域:

康复机器人康复机器人
运动学习是指运动学习.
虚拟现实 (VR) 应用程序

背景情况:

虚拟现实 (VR) 和沉浸式虚拟现实 (IVR) 对于运动 (再) 学习是有效的,低成本的头戴显示器 (HMD) 使它们成为可行的康复工具.
为复杂的运动任务设计有效的IVR环境,例如用下肢外骨架启动步行,仍然是一个挑战.
复杂的步行任务包括重量转移,干部稳定和步骤启动等子任务,需要特定的训练策略.

研究的目的:

调查VR中的最佳设计元素,以增强复杂的虚拟步行任务的运动学习.
为了确定不同虚拟现实 (VR) 视角和视觉反的有效性,用于训练外骨架辅助行走.

主要方法:

开发了一个模拟虚拟行走的HMD-IVR系统,用于控制可穿戴的下肢外骨架.
对40名健康参与者进行了一项实验,比较第一人称 (1PP) 与第三人称 (3PP) 的视角以及并发的视觉反.
评估行走表现 (步骤,干倾斜,步伐长度),实施方式,可用性,网络疾病和感知的工作量.

主要成果:

所有参与者都成功地学习了虚拟步行任务.
没有一个单独的视角和反的组合普遍改善了所有子任务的学习;最佳的培训是特定于子任务的.
报告了高水平的化身体现和低的网络疾病,但认知负载仍然很高,影响了可用性.

结论:

分任务的顺序训练,使用定制的视角和视觉反的组合,最大限度地提高了复杂的步行任务的运动学习.
这些发现为开发先进的IVR系统提供了关键的见解,以帮助有感觉运动障碍的人学会用外骨行走.
优化VR设计元素是提高基于外骨的康复疗法的关键.
