医学教育在检测表面下肿瘤方面有很强的触诊训练需求。为了满足这一需求，创建了虚拟现实训练模拟。利用Rutgers Master II力反馈系统，模拟允许受训者执行患者检查并触诊（触摸）患者的虚拟肝脏以搜索表面下的硬区域。当用户的指尖经过一个“肿瘤”时，实验确定的力/挠度曲线被用来给用户一种表面下物体的感觉。开发了图形用户界面以方便导航并提供培训测验。受训者被要求识别肿瘤的位置和相对硬度，并根据位置和诊断错误评估其表现。模拟训练结果与生物力学分析结果一致。1997爱思唯尔科学有限公司
Medical education has a strong need for palpation training in the detection of subsurface tumors. A virtual reality training simulation was created to address this need. Utilizing the Rutgers Master II force feedback system, the simulation allows the trainee to perform a patient examination and palpate (touch) the patient's virtual liver to search for hard regions beneath the surface. When the user's fingertips pass over a 'tumor', experimentally determined force/deflection curves are used to give the user the feeling of an object beneath the surface. A graphical user interface was developed to facilitate navigation as well as provide a training quiz. The trainee is asked to identify the location and relative hardness of tumors, and performance is evaluated in terms of positional and diagnosis errors. The results of this training simulation are in agreement with biomechanical analysis. (C) 1997 Elsevier Science Ltd.
