SIMmersion role-play simulations create interactive experiences that help learners build and retain critical communication skills required for applications like suicide interventions, sales or negotiations. Learners talk with a realistic simulated person with assistance from an on-screen coach. The coach provides continuous non-verbal feedback, but users can ask for detailed help at any time. A complete after-action review provides quantitative and qualitative feedback and an instant replay feature. Users communicate with the video-taped simulated character using a microphone or a mouse. The result is a nearly free-form conversation that is different each time. Systems are delivered over the internet through a web browser, on mobile devices, as a thin-client application, or on DVDs.
