HumanSim Physiology Engine
ARA’s HumanSim physiology engine enables realistic, real-time medical training. The engine is based on the work of N. Ty Smith, M.D. and colleagues. The engine outputs real-time clinically relevant data, such as heart rate, blood pressure (arterial and pulmonary) waveforms and a capnogram. The engine enables dynamic medical scenarios (as opposed to scripted) and provides an environment for on-the-spot medical decision making.
The engine includes cardiovascular and respiratory models, as well as gas exchange and drug transport models. The cardiovascular and respiratory models are extensions of the Enhanced Fukui-Smith model. The cardiovascular system is modeled with a series of fifteen compartments representing various organ systems, including the pulsatile power generation capabilities of both the right and left heart that drive the entire cardiovascular system. The respiratory system is modeled by a series of six compartments that represent the various airway components, including the thoracic cavity pressure and elastic recoil of the chest wall that drive negative pressure ventilation (free breathing). The respiratory system is also capable of representing positive pressure ventilation (ventilated or forced breathing), by replacing the driving mechanism of negative pressure ventilation with an eight compartment model of a ventilator. This provides the required flexibility to represent the clinical environment of an operating room.
‘GO’ Platform
GO brings high-fidelity, immersive training environments to any Windows computer through a web browser. Central access to GO’s training modules via the web is easy and training content and records are always up-to-date. GO can be hosted on your IT infrastructure or by ARA.
GO is a single/multi-player immersive training and education platform based on Epic Games’ Unreal® Engine 3. GO consists of a series of ActiveX/Netscape plug-ins that contain the Unreal Engine connected to backend computer server infrastructure. Content released on the GO platform is accessed via a web server that provides pages containing content plug-ins as well as an interface to access specific training applications, as authorized by the user database. A sample plug-in is available to allow visitors to meet and converse in a 3D showcase environment and provides a way for users to navigate to other training environments. Browsers currently supported are: Internet Explorer 8 and 9, Firefox 3 and 4, Safari, Chrome, Opera.
Unreal Technology
Unreal Engine 3 (UE3) is a ‘Made in the USA’ complete development framework for PCs, Xbox 360®, iOS, Android™ and PlayStation® 3, providing a vast array of core technologies, content creation tools, and support infrastructure content.
UE3 is integrated with leading middleware technologies through Epic Games’ Integrated Partners Program. Continual optimizations are made to the Unreal Engine’s highly mature tool pipeline, massive world support and multi-processor performance. UE3’s advanced toolset is designed specifically to accelerate developers’ productivity for ultra-complex, next-generation content.
From entertainment software to training simulations, the Unreal Engine provides the platform and tools needed to develop cutting-edge 3D projects. UE3 is the four-time winner and Hall of Fame recipient of Game Developer magazine’s Best Engine Front Line Award. Develop magazine calls it the number one game engine as well.
zSpace
HumanSim is currently working closely with Infinite Z, Inc. to explore the use of zSpace® technology for use in medical education and training. We are establishing production pipelines to get our Unreal content into zSpace quickly and efficiently for our clients.
zSpace provides a highly realistic stereoscopic 3D visualization experience that enables designers and engineers to work with products or characters in a way not previously possible in a traditional 2D display and mouse.
Features and Benefits:
- Virtually holographic images appear “solid” in open space as if they are real physical objects
- Intuitive user interface requires no advanced training. Users navigate, manipulate and explore models as never before possible
- High-definition stereoscopic display with full images rendered for each eye for ultra-high realism
- Lightweight passive trackable eyewear for viewing comfort
- Full motion parallax, with sensors tracking the viewing angle, enabling the user to look around objects and visualize multiple perspectives with simple head movements
- Uniquely designed stylus for managing direct and natural interactions with virtually-holographic images in 3D space
