注意誘導のための視覚的注意のモデル化

ロボットが人間と円滑なインタラクションを行うためには、人間の注意や行動を適切に誘導することが重要です。本研究では、手品という極端な注意誘導の例を解析し、その結果に基づいて人間の視覚的注意のモデル化を行っています。

abstract
In order to smoothly interact with humans, it is desirable that a robot can guide human attention and behaviors. In this study, we developed a model of human visual attention for guiding human attention based on an analysis of a magic trick performance. We measured human gaze points of people watching a video of a magic trick performance and compared them with the area where the magician intended to draw a spectator’s attention. The analysis showed that the relationship between the magician’s face, hands, and gaze plays an important role in guiding the spectator’s attention. On the basis of the preliminary user studies on watching the magic video, we integrated a saliency map and a manipulation map that describes the relationship between gaze and hands to develop a novel human attention model. The evaluation using the observed gaze points demonstrated that the proposed model can better explain human visual attention than the saliency map while people are watching a video of a magic trick performance.
