Towards Rapid Development of Conversational Virtual Humans using Web3D Technologies

In this paper, we propose a framework for the rapid development of conversational virtual humans (VHs) via the web. Web3D formats, such as WebGL, have enabled the use of interactive VHs on the web. Web-based conversational VHs are found to have great potential in improving population health. However, the development of web-based VHs needs significant time and effort which can lead health experts to avoid VH technology. In this paper, we present a case study to highlight the challenges that lead to significant time and effort in the development of web-based conversational VHs. Based on our findings, we propose a framework that uses Web3D formats and has the potential to address identified challenges in the rapid development of web-based conversational VH systems.
