Although human actions can be inferred from a wide range of data, it has been demonstrated that simple human actions can be inferred by tracking the movement of the head in 2D.  ...  We present experimental results to demonstrate the potential of using 3D head trajectory information to distinguish among simple but common human actions independently of viewpoint.  ...  CONCLUSIONS AND FUTURE WORK We presented a system for recognizing several simple human actions by analyzing the movement of the head in 3D.  ...

Human Action Recognition by Inference of Stochastic Regular Grammars [chapter]

Kyungeun Cho, Hyungje Cho, Kyhyun Um
2004 Lecture Notes in Computer Science  
This recognition method is tested by using 900 actions of human upper body.  ...  In this paper, we present a new method of recognizing human actions by inference of stochastic grammars for the purpose of automatic analysis of nonverbal actions of human beings.  ...  In this experiment we don't use the ANMC because head actions have all same movement complexity. 40 action data are used for learning and 32 action data for testing.  ...

The avatar has lip syncing (phoneme control), head gesture and facial expression (using either facial action units or cardinal emotion categories) capabilities.  ...  We release code and models to illustrate how the avatar can be controlled like a puppet or used to create a simple conversational agent using public application programming interfaces (APIs).  ...  We use the facial action unit probability scores from the Facial Action Unit Recognizer to control the avatar's facial action controls and mimic the human facial expressions.  ...

Active eye contact for human-robot communication

Dai Miyauchi, Arihiro Sakurai, Akio Nakamura, Yoshinori Kuno
2004 Extended abstracts of the 2004 conference on Human factors and computing systems - CHI '04  
Thus, there has been a great deal of research on using gaze or eye movements for human interfaces, which can be considered as communication between humans and machines.  ...  Then, we present a robot that can recognize hand gestures after making eye contact with the human to show the effectiveness of eye contact as a means of controlling communication.  ...  We use a mobile robot Pioneer 2 by ActivMedia. A laptop PC is placed on it so that a 3D CG human head is shown at an appropriate height.  ...
