An Approach to Estimating Human Behaviors by Using an Active Vision Head

When an intelligent robot works together with human in a living space, we may often encounter a scene that the robot supports the human behaviors. Understanding of the human behavior is required for the robot to judge what kind of action serves as assistance to the human in such a scene. The present research aims at constructing a system that can understand the human behavior using the time series images for the movement of the human, which can be obtained from an active vision head. The first process estimates the human posture in each frame. The next process divides the basic human action into a posture and a position. The final process estimates the human behavior by examining the action and the target, under the assumption that the human behavior consists of the combination of an action and a behavioral target
