Scenarios in virtual learning environments for one-to-one communication skills training

A scenario is a description of a series of interactions between
a player and a virtual character for one-to-one communication skills
training, where at each step the player is faced with a choice between
statements. In this paper, we analyse the characteristics of scenarios and
provide a classification to represent such scenarios. The analysis is performed
through a literature review and by comparing virtual learning
environments for scenario based training. Using this analysis we specify
requirements for describing communication scenarios related to their:
structure (linear, branching, interleaving), properties (static information
stored per scenario like situation, background, which virtual character to
show), and parameters (characteristics of a scenario that can be modified
per statement like a score on a learning goal and an emotional e↵ect in
a virtual character). We define a schema for representing such communication
scenarios and present an authoring tool to create a scenario.
