CIn this paper, I discuss the minimization of the user interface of the interactive fairy tale content based on BCI and Motion Sensing Technology. For this reason, 3 version intervention interfaces of the interactive fairy tale content with Microsoft's Kinect as a non-contact motion sensing device and NeuroSky's MindWave EEG biosensor device as a BCI interface were produced and experimented. The experiments have been accomplished for four children of the first or the second graders by examining three different interactive intervention interfaces: 1) attention indicator by sparkling light; 2) the attention indicator plus behavior instructions; and 3) an indication bar for the attention level plus behavior instructions. As a result of this experimental observations, it shows that the visualized interface such as icons helps the participating children communicate with the fairy tale content system. In addition, they do communicate well without the visualized graphical interfaces when they are demanded by the realistic actions. Whereas, some communication problems have been found neither the realistic actions are requested nor the attention indicators are provided definitely.
