Animating an Autonomous 3D Talking Avatar [article]

Dominik Borer, Dominik Lutz, Martin Guay
2019 arXiv   pre-print
To our knowledge, there is no automatic method that can process animations and automatically label actions and compatibility between them.  ...  We measured the time required to label actions of an embodiment using our simple interface, compared to the standard state machine interface in Unreal Engine, and found that our approach is 7 times faster  ...  Introduction Intelligent avatars that can talk and interact with people offer a natural and friendly way to interface with autonomous systems-may they be cars, televisions, food dispensers, phones, maps  ...

From Virtual Environment to Virtual Community [chapter]

A. Nijholt
2001 Lecture Notes in Computer Science  
Typically, visitors can present themselves by choosing an avatar (a 2D object) and its predefined animations. These animations are simple (a waving gesture, a jump of joy, . . .).  ...  Before going into a description of our own environment and its development we survey the research areas that now allow the building of 3D embodied and animated agents that show intelligence and personality  ...  This system also animates avatars in an online graphical chat environment.  ...

A Life-Like Agent Interface System with Second Life Avatars on the OpenSimulator Server [chapter]

Hiroshi Dohi, Mitsuru Ishizuka
2009 Lecture Notes in Computer Science  
This paper describes a design of a life-like agent interface system with Second Life avatars on a 3D virtual world.  ...  Although it is still an alpha version and has various problems at present, it has many advantages. Our avatar can be controlled by event-driven.  ...  A user can talk with her like a videophone. Our research goal is to realize autonomous agents on 3D virtual world.  ...

A Framework for Human-like Behavior in an immersive virtual world

Fons Kuijk, Sigurd Van Broeck, Claude Dareau, Brian Ravenet, Magalie Ochs, Konstantinos Apostolakis, Petros Daras, David Monaghan, Noel E O'Connor, Julie Wall, Ebroul Izquierdo
2013 2013 18th International Conference on Digital Signal Processing (DSP)  
Rather than just being visualized in a 3D space, the virtual characters (autonomous agents as well as avatars representing users) in the immersive environment facilitate social interaction and multi-party  ...  Represented by realistic virtual characters, this framework allows people to feel immersed in an Internet based virtual world in which they can meet and share experiences in a natural way as they can meet  ...  d) Obstacle Avoidance & Path Finding This component is responsible for providing collision free paths for autonomous agents and semi-autonomous avatars to allow them to navigate through the 3D virtual  ...

Improving Communication in 3D Virtual Environments by Means of Task Delegation in Agents [chapter]

Ricardo Imbert, Angélica de Antonio, Javier Segovia
2001 Lecture Notes in Computer Science  
User-to-User Communication within Internet-based 3D Virtual Environments is usually difficult mainly due to the trade-off between the capability and the complexity of the interface.  ...  An avatar-agent is semi-autonomous, meaning that it takes its own decisions of what to do after an event, for example moving the head towards the nearby avatar or going away, but under certain circumstances  ...  an Event Perceiver that will allow it to react semi-autonomously to the external events.  ...

Analogous to how talking on the telephone does not replicate the experience of talking in person.  ...  Fuzzy logic theory is an ideal medium for embedding this autonomous behavior in the users' avatar.  ...  An avatar reasoning module deals with autonomous behavior, physical interaction and emotional engagement regarding the virtual humanoid characters.  ...

The outputs are shown on a screen displaying 3D signing avatar and on a touchscreen displaying graphical user interface.  ...  Its functionality was tested on a prototype of an information kiosk for the deaf people providing information about train connections.  ...  We use the signing avatar animation in two forms. The first is an on-line generated avatar shown on the large screen that provides real-time feedback to deaf users.  ...

Physical Embodiment Can Produce Robot Operator's Pseudo Presence

Kazuaki Tanaka, Hideyuki Nakanishi, Hiroshi Ishiguro
2015 Frontiers in ICT  
To find the effects, we conducted an experiment in which subjects talked with a partner through robots and various existing communication media (e.g., voice, avatar, and video chats).  ...  When a subject interacted with an autonomous robot after interacting with a teleoperated robot (i.e., a remote operator) that is identical with the autonomous robot, the subjects tended to feel as if they  ...  Grant Number 26280076 "Robot-Enhanced Displays for Social Telepresence, " SCOPE "Studies and Developments on Remote Bodily Interaction Interfaces, " and KDDI Foundation Research Grant Program "Robotic Avatars  ...
