Avatar Gestures

چکیده
This paper describes the concept and control of a 3d Avatar system with mimic and gestures as a conversational user interface. The Avatar system including gestures and mimic is based on morphing techniques. It allows to generate sign language and mouth motion at lip reading quality in real time. The concept of a Speech Act is introduced and a table is defined to classify conversation fragments. Furthermore, two rule-based systems have been implemented to control the Avatar’s behavior and gestures. The system is shown to be useful in several application areas.

Effective Pedagogical Agent Behaviour
This paper describes a small experimental study where pedagogical agents (avatars) are added to voice-over-slide learning materials. Four different agent behaviours are tested: Avatar A performs all the upper-body gestures of the lecturer; Avatar B is animated using few random gestures in order to create a natural presence, but one that is unrelated to the speech; Avatar C only performs the lec...
متن کاملTalk to the Virtual Hands: Self-Animated Avatars Improve Communication in Head-Mounted Display Virtual Environments
BACKGROUND When we talk to one another face-to-face, body gestures accompany our speech. Motion tracking technology enables us to include body gestures in avatar-mediated communication, by mapping one's movements onto one's own 3D avatar in real time, so the avatar is self-animated. We conducted two experiments to investigate (a) whether head-mounted display virtual reality is useful for resear...
متن کاملReal-time Gesture Recognition for the Control of Avatar
There are many attempts to use the gestures for the natural human computer interface. Most of systems use the tracking devices to capture the human motion and display. In this paper, we propose a gesture recognition system for natural interface between the participant and his own avatar in virtual environment only using two polhemus sensors attached on the arm. Our system has two modes for the ...
متن کاملA Markerless Gestural Interface for Avatar Control
This project serves as a gestural interface for searching a motion capture database. This system is intended to handle the gestures of a wide range of users employing algorithms that were trained on gestures identified in a user study. With this system, users can act out gestures in front of a natural interaction device, which will trigger different behaviors of an on-screen character. This ine...
متن کاملUsers’ views of Facial Expressions and Body Gestures in E-Learning Interfaces: an Empirical Evaluation
This paper introduces an experimental study performed to investigate the usability aspects of elearning interfaces that incorporate the use of avatar as a virtual lecturer. A within-subject experiment has been conducted using three different e-learning interfaces which were developed from scratch and tested by a group of 48 users. Each of these three interfaces involved the use of a human-like ...
