Preoperative planning and intraoperative assistance are needed to improve accuracy in tumour surgery. To be accepted, these processes must be efficient. An experiment was conducted to compare a mouse and a haptic device, with and without force feedback, to perform plan positioning in a 3D space. Ergonomics and performance factors were investigated during the experiment. Positioning strategies were observed.
The task completion time, number of 3D orientations and failure rate were analysed. A questionnaire on ergonomics was filled out by each participant.
The haptic device showed a significantly lower failure rate and was quicker and more ergonomic than the mouse. The force feedback was not beneficial to the accomplishment of the task.
The haptic device is intuitive, ergonomic and more efficient than the mouse for positioning a 3D plane into a 3D space. Useful observations regarding positioning strategies will improve the integration of haptic devices into medical applications.
为了提高肿瘤手术的准确性，需要术前规划和术中协助。为了被接受，这些过程必须是高效的。进行了一项实验，比较了鼠标和触觉设备，有无力反馈，以在 3D 空间中执行计划定位。在实验过程中研究了人体工程学和性能因素。观察了定位策略。
分析了任务完成时间、3D 方向数和失败率。每位参与者都填写了一份关于人体工程学的问卷。
触觉设备的失败率明显较低，比鼠标更快、更符合人体工程学。力反馈不利于任务的完成。
触觉设备用于将 3D 平面定位到 3D 空间中，比鼠标直观、符合人体工程学且更高效。关于定位策略的有用观察将提高触觉设备在医疗应用中的集成度。
