VERSE: Workflows for simulation and virtual world telemetry and control

Ellaway R., Sanche R., Symington C., Topps D.

Simulation involves learners engaging in practices that replicate real-world practice. Feedback and other educational benefit is derived both from direct observation and from the analysis of data capture representing learner actions. Many if not most information systems generate logs and other records of their use but these are usually stored in or in close proximity to the device or system itself. A number of newer systems provide some kind of API (application programming interface) for accessing and controlling them from elsewhere. Telemetry is the remote recording and analysis of data and information. The VERSE project (Virtual Educational Research Services Environment) has been funded by the Canadian Fund for innovation to develop virtual reality research infrastructure. The project has focused on two areas: a) creating a centralized system for capturing telemetry from multiple and heterogeneous devices and b) distributed control of authoring and the execution of simulation activities using OpenLabyrinth and Second Life. This presentation will explain and demonstrate the work of the VERSE project and describe the data models and workflows for the remote capture of simulation telemetry and how a game state engine can be used to control events and interactions in a virtual world platform.

HSVO: a functional XML specification for integrating simulation devices

Although we live in a time where systems and sen/ices are combined and integrated in more and more useful ways, there are still many data silos. Simulation for healthcare education is a notable example where although there has been a proliferation of devices and services there Is little connectivity or integration between them. The MedBlquitous Virtual Patient specification affords a degree of sharing of content but not runtime data and there Is nothing that these other forms to this model. The Healthcare Services Virtual Organization (HSVO) project has developed an XML-based messaging specification as part of a network-enabled platform that can connect, run, control and exchange data between any services connected to its messaging bus. Middleware interfaces essentially 'wrap' each service translating Its native functions Into a set of common actions and parameters to be exchanged with other services on the bus. The HSVO NEP also involves the use of lightpaths and services that include the Open Labyrinth virtual patient platform, the Laerdal SimMan 3G, stereoscopic and tomographic datasets, physiological algorithms and camera arrays. This presentation will present the rationale for the specification, the XML model itself and examples of how it works in practice.
