AIMS
The HTC VIVE virtual reality (VR) system is a potential tool for collecting kinematic data during inpatient and outpatient physical therapy (PT). When validated against research-grade systems, the VIVE has a reported translational error between 1.7 mm-2.0 cm. Our purpose was to portabilize the VIVE for room to room PT and validate the motion tracking software.
METHODS
The VIVE was configured on a mobile cart. To validate the motion tracking software, the VIVE sensors (motion tracker, controller, headset) were mounted on a rigid linear track and driven through 10, one-meter translations in the X, Y, and Z axes.
RESULTS
The mean translational error for all three sensors was below 4.9 cm. While error is greater than that reported for research-grade systems, motion tracking software on the portable VIVE unit appears to be a valid means of tracking aggregate movement.
CONCLUSION
Some therapy may require more precise measurements, however, the advantages of portability and accessibility to patients may outweigh the limitation of reduced precision.
目的
HTC VIVE虚拟现实（VR）系统是在住院和门诊物理治疗（PT）期间收集运动学数据的潜在工具。与研究级系统相比，VIVE的平移误差据报道在1.7毫米至2.0厘米之间。我们的目的是将VIVE便携化以便在不同房间进行物理治疗，并验证其运动跟踪软件。
方法
将VIVE配置在移动推车上。为了验证运动跟踪软件，将VIVE传感器（运动追踪器、控制器、头戴式设备）安装在刚性直线轨道上，并在X、Y和Z轴上进行10次一米的平移驱动。
结果
所有三个传感器的平均平移误差均低于4.9厘米。虽然误差大于研究级系统报告的误差，但便携式VIVE单元上的运动跟踪软件似乎是跟踪总体运动的有效手段。
结论
某些治疗可能需要更精确的测量，然而，便携性和患者可及性的优点可能超过精度降低的局限性。
