Alexander Maasch from project partner chemmedia AG also presented research concerning the visualization of conversation training data. Conversation training is an e-learning method designed for the transfer of communication-related skills. With increasing conversation length and number of learners, creating and evaluating conversations becomes a complex task that needs appropriate visual guidance and data visualization. This paper shows the inherent complexities of conversation trainings and guides through an approach that eases the conversation creation. In the talk, we explained data collection with Experience API and finally we presented a Sankey Diagrams based approach to visualize large amounts of collected learning data.
