Presenter Supporting System with Visual-Overlapped Positive Response on Audiences

When we speak in public, we sometimes fail to speak well because of anxiety and strain. To solve such a problematic situation, we propose a method of overlapping positive response on audiences, and implement the system which overlaps an image of smiling pumpkin with nodding on each audience using video see-through HMD. As the result of an experimental evaluation of the proposed system, it is found that this system can reduce the anxiety and strain compared with the situation that scowling audiences are in view. It is considered that the result comes from two facts: (1) participants’ anxiety and strain increase in case that audiences or pumpkins are scowling, and (2) they decrease in case that audiences or pumpkins are smiling. In addition, it is found that the feeling of relief and satisfaction, which are factors of reducing the anxiety and strain, are more improved in smiling pumpkins than smiling audiences.
