为了开发虚拟现实（VR）在医学中的潜力，必须仔细选择输入设备，因为它们具有不同的优点。在这项工作中，输入设备的医疗VR规划和培训中常见的交互任务进行了比较。根据具体目的，存在不同的要求。因此，必须在满足特定任务要求和拥有广泛适用的设备之间找到适当的权衡。我们专注于两个医疗用例，肝脏手术规划和开颅手术培训，以涵盖广泛的医疗领域。在此基础上，对相关输入设备进行了比较，以确定它们是否适合执行精确的VR交互任务。这些设备是标准的VR控制器，笔状VR墨水，数据手套和真实的开颅器，用于开颅手术的医疗器械。基于不同的测量，定量地比较了输入设备的性能。控制器和VR Ink在精度方面的表现明显优于其余两种器械。评估了有关任务负荷、晕电脑病以及器械可用性和适当性的定性数据。虽然没有设备在这两种应用中脱颖而出，但大多数参与者更喜欢使用VR Ink，其次是控制器，最后是数据手套和开颅器。这些结果可以指导未来医疗VR应用选择合适的设备。
To exploit the potential of virtual reality (VR) in medicine, the input devices must be selected carefully due to their different benefits. In this work, input devices for common interaction tasks in medical VR planning and training are compared. Depending on the specific purpose, different requirements exist. Therefore, an appropriate trade-off between meeting task-specific requirements and having a widely applicable device has to be found. We focus on two medical use cases, liver surgery planning and craniotomy training, to cover a broad medical domain. Based on these, relevant input devices are compared with respect to their suitability for performing precise VR interaction tasks. The devices are standard VR controllers, a pen-like VR Ink, data gloves and a real craniotome, the medical instrument used for craniotomy. The input devices were quantitatively compared with respect to their performance based on different measurements. The controllers and VR Ink performed significantly better than the remaining two devices regarding precision. Qualitative data concerning task load, cybersickness, and usability and appropriateness of the devices were assessed. Although no device stands out for both applications, most participants preferred using the VR Ink, followed by the controller and finally the data gloves and craniotome. These results can guide the selection of an appropriate device for future medical VR applications.
