在医学教育领域，迫切需要触诊培训，以满足检测皮下肿瘤的特定需求。为了满足这一需求，创建了虚拟现实培训模拟。利用Rutgers Master II力反馈系统，模拟允许用户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“肿瘤”时，实验确定的力/偏转曲线用于给用户表面下的物体的感觉。开发了一个图形用户界面，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表现。
In the area of medical education, there is a strong need for palpation training to address the specific need of detecting 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 user 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 providing 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 diagnostic errors.
