Context
• Simulation in med-ed increasingly multi-modal and
multifaceted
• wealth of devices such as mannequins and task trainers
• actors play simulated patients
• increased use of screen-based simulations, ranging from
narratives to immersive worlds like Second Life
• Despite richness of simulation modes, each modality stands
alone, unable to connect or interoperate with any other
![Page 3: Interfacing High Fidelity Mannequins with Web- Based Training Rachel Ellaway, Ph.D. 1,2, David Topps MD 1 1 Northern Ontario School of Medicine, 2 St George’s](https://reader030.vdocuments.us/reader030/viewer/2022032800/56649d235503460f949f90e5/html5/thumbnails/3.jpg)
Reasons for doing this
• Limitations of independent modes
• Poor ROI, poor breadth of POV
• Needs, creativity, mash-up age
• Preparation for practice still arbitrary
![Page 4: Interfacing High Fidelity Mannequins with Web- Based Training Rachel Ellaway, Ph.D. 1,2, David Topps MD 1 1 Northern Ontario School of Medicine, 2 St George’s](https://reader030.vdocuments.us/reader030/viewer/2022032800/56649d235503460f949f90e5/html5/thumbnails/4.jpg)
Dimensions of the Continuum
• Continuum of experience – sequence and cluster
• Continuum of mechanics – physical integration
• Continuum of data – aggregate and exchange
• Continuum of modeling – parallax and triangulation
![Page 5: Interfacing High Fidelity Mannequins with Web- Based Training Rachel Ellaway, Ph.D. 1,2, David Topps MD 1 1 Northern Ontario School of Medicine, 2 St George’s](https://reader030.vdocuments.us/reader030/viewer/2022032800/56649d235503460f949f90e5/html5/thumbnails/5.jpg)
Dimensions of Integration
• Technical Integration – connectivity, exchange, control
• Presentational integration – real world, synthetic, hybrid
• Narrative integration
• Evaluation integration
• Rules systems
• Activity systems

Growing integration
• Simulation labs – integration by proximity
• Roger Kneebone – Part Task Sims + Std Patients
• SGUL &Daden – Second Life and MVP
• Mannequins + EHRs
• Jacobson imaging as simulation

Edge Wrapper
Edge Service = Edge Device + Wrapper
Wrappers have two sides:
![Page 16: Interfacing High Fidelity Mannequins with Web- Based Training Rachel Ellaway, Ph.D. 1,2, David Topps MD 1 1 Northern Ontario School of Medicine, 2 St George’s](https://reader030.vdocuments.us/reader030/viewer/2022032800/56649d235503460f949f90e5/html5/thumbnails/16.jpg)
Messaging
Service specification based on messaging and edge service behaviours:
<message sessionID=”ABC” deviceID=”123” action=”sessionStatus”><configuration ID=”456” value=”act1” type=”cdata” /><parameter ID=”456” value=”0” type=”int” /><parameter ID=”789” value=”60” type=”mmHg” /></configuration></message>
<message sessionID=”ABC” deviceID=”123” action=”transferData”><parameter ID=”456” value=”10” type=”int” /><parameter ID=”789” value=”50” type=”mmHg” /></message>

Service Specification
Components:
• Messaging – to and from the Eye
•Behaviours – in response to messages
Defines how a service works
Defines wrapper:wrapper = service – device capability
Allows for any future device or variant to be added to the HSVO NEP framework

![Page 22: Interfacing High Fidelity Mannequins with Web- Based Training Rachel Ellaway, Ph.D. 1,2, David Topps MD 1 1 Northern Ontario School of Medicine, 2 St George’s](https://reader030.vdocuments.us/reader030/viewer/2022032800/56649d235503460f949f90e5/html5/thumbnails/22.jpg)
NEP STEP
• Services for Telemetrics & Evaluation of Performance
• Builds on HSVO to include:– Extended services
– New services
– Platforms as services – ONE-ITS, CBRAIN
• Telemetrics streaming• Telemetrics coding• Telemetrics modeling• Savoir3

SISTER
• SISTER: Simulation Integration Specification for Technology Enhanced Research
• an integration specification for simulation platforms
• simple, extensible, open
• still in R&D but looking to implement soon
• ? Candidate (Canadadidate?) for future spec process
![Page 24: Interfacing High Fidelity Mannequins with Web- Based Training Rachel Ellaway, Ph.D. 1,2, David Topps MD 1 1 Northern Ontario School of Medicine, 2 St George’s](https://reader030.vdocuments.us/reader030/viewer/2022032800/56649d235503460f949f90e5/html5/thumbnails/24.jpg)
Challenges
• Profound heterogeneity
• Black boxes – commercial implementation
• Endpoints, APIs and their complete absence
• Benefits of implementation – still in R&D
• SISTER is a research spec at present
• Levels of integration and control
• Exchange – semantics, flow, emergence
• Defining conceptual as well as technical spaces
![Page 25: Interfacing High Fidelity Mannequins with Web- Based Training Rachel Ellaway, Ph.D. 1,2, David Topps MD 1 1 Northern Ontario School of Medicine, 2 St George’s](https://reader030.vdocuments.us/reader030/viewer/2022032800/56649d235503460f949f90e5/html5/thumbnails/25.jpg)
Ways Forward
• Paths of intention demonstrate need and potential
• Many ways to implement simulation continua
• Classic opportunity for standards activity
• Key role in bridging safely and confidently into practice
