Analytical Steps for the Validation of a Natural User Interface

Pedagogical Agents are primarily researched regarding their depiction or appearance on screen, rather than their capabilities to react to a learner in front of it. As it has been previously reported, we developed an agent system, which is based on an electronic educational instance for a learning module to incorporate information from the environment as well as non-verbal reactions of a user. The system is then capable of proactively reacting to this additional information, establishing a natural user interface as it might be expected by any user. In order to validate our approach, the steps for our experimental setup are presented and discussed.
