Flight simulators offer pilots a chance to safely practice flying a wide range of aircraft in a variety of scenarios. Similarly, human patient simulators offer nurses and physicians safe opportunities to practice healthcare on a wide range of patients and scenarios. Virtual patient simulators use computer graphics to render humans with a range of visual characteristics including medical symptoms, personality, race, and gender. However, they are inherently virtual--practitioners cannot manipulate them with their hands. Manikin-based patient simulators on the other hand are inherently physical, comprising human-sized bodies with realistic skin and electro-mechanical simulation of physiological symptoms. They afford a "hands on" experience but are very limited in their ability to present visual characteristics. Furthermore, medical educators are increasingly focusing on interpersonal skills and cultural competency, as these impact provider-patient relationships, diagnoses, and treatments. Manikins do not afford the associated humanistic traits.The researchers on this project are developing a Physical-Virtual Patient Bed (PVPB) that combines the flexibility of virtual patients with the physicality of manikins. The PVPB will employ dynamic computer graphics rear-projected onto a body-shaped shell mounted in a real hospital bed, along with various sensors and actuators, to create a patient simulator that talks; appears to sweat, breathe, and squirm; exhibits a pulse; feels warm/cold on various body parts; and responds to touch by humans or medical instruments. It will be able to change race, gender, and visually-apparent symptoms on the fly, and will exhibit real human emotional complexity via real human agency. The researchers will assess the effectiveness of the PVPB in simulating certain conditions, and use it to develop new knowledge about the relative importance of various patient cues, and provider biases arising from patient demographics.

飞行模拟器为飞行员提供了在各种情况下安全地练习驾驶各种飞机的机会。同样，人类患者模拟器为护士和医生提供了安全的机会，可以在各种患者和场景中进行医疗保健。虚拟患者模拟器使用计算机图形来呈现具有一系列视觉特征的人类，包括医学症状、个性、种族和性别。然而，它们本质上是虚拟的-从业者不能用手操纵它们。另一方面，基于Manikin的患者模拟器本质上是物理的，包括具有逼真皮肤的人类大小的身体和生理症状的机电模拟。他们提供了一个“动手”的经验，但在他们的能力非常有限，目前的视觉特征。此外，医学教育工作者越来越关注人际交往能力和文化能力，因为这些影响医患关系，诊断和治疗。人体模型不具备相关的人文特征。该项目的研究人员正在开发一种物理虚拟病床（PVPB），将虚拟患者的灵活性与人体模型的物理性结合起来。PVPB将采用动态计算机图形后投影到安装在真实的医院病床上的身体形状外壳上，沿着各种传感器和致动器，以创建一个患者模拟器，该患者模拟器可以说话;似乎出汗，呼吸和蠕动;显示脉搏;感觉身体各部位的温暖/寒冷;并对人类或医疗器械的触摸做出反应。它将能够改变种族、性别和视觉上明显的症状，并将通过真实的人类媒介展示真实的人类情感复杂性。研究人员将评估PVPB在模拟某些条件下的有效性，并利用它来开发有关各种患者线索的相对重要性以及患者人口统计数据引起的提供者偏见的新知识。
