| Outline of Final Research Achievements |
This study conducted the analysis on conversational errors, i.e., falling into silence for more than 1 minute as undesirable situation in collaborative environments.
1) This study compared between temporal changes in frequency of turn taking and variation of brain waves during the exercise of pair programming. From the experimental result, variation of brain waves is larger at the point the transition from active conversation to falling into silence. In other words, the effects on brain activity by conversational errors between the collaborators can be visualized by the index, variation of brain waves.
2) This study also conducted the experiment of mental arithmetic task by simultaneous EEG and NIRS monitoring, and classified the brain states using Self-Organizing Maps (SOMs). From the experimental result, our discussion concluded that not only the states of calculating and resting, but also the states of eye-closing, listening and writing are classifiable.
