电动轮椅的接口选项有限，这导致一些人无法独立驾驶。此外，新界面技术的开发将需要开发替代培训方法。这项研究在虚拟环境和真实环境中的驾驶任务中将传统的位置传感操纵杆与新型等距操纵杆进行了比较。结果显示，两种类型的操纵杆之间的任务完成时间和均方根误差（RMSE）几乎没有差异。对于两种类型的操纵杆，虚拟环境和真实环境中的 RMSE 之间存在显着相关性。数据表明，虚拟环境中的性能代表了真实环境中的驾驶能力，等距操纵杆的性能与位置传感操纵杆相当。(C) 2002 IPEM。由爱思唯尔科学有限公司出版。保留所有权利。
There are limited interface options for electric powered wheelchairs, which results in the inability of some individuals to drive independently. In addition, the development of new interface technologies will necessitate the development of alternative training methods. This study compares a conventional position sensing joystick to a novel isometric joystick during a driving task in a virtual environment and a real environment. The results revealed that there were few differences in task completion time and rootmean-square error (RMSE) between the two types of joysticks. There were significant correlations between the RMSE in the virtual environment and the real environment for both types of joysticks. The data indicate that performance in the virtual environment was representative of driving ability in the real environment, and the isometric joystick performed comparably to the position sensing joystick.(C) 2002 IPEM.
