What is 3-Dimensional Virtual Learning Environment (3D-VLE)

Online systems, especially 3D virtual environments, hold great potential to enrich and expand learning opportunities for those who are challenged by traditional modes of instruction and interaction. In the process of developing a 3D Virtual Learning Environment to support the development and practice of social competence for individuals with Autism Spectrum Disorders, the iSocial project explored and advanced ideas for social orthotics in virtual environments. By social orthotics the authors mean structures in the environment that overcome barriers to facilitate social interaction and social learning. The vision of social orthotics in a 3D world is to be both assistive and adaptive for appropriate social behavior when the student, peers and guide are represented by avatars in a 3D virtual world designed to support learning and development. This chapter describes the formulation of social orthotics for avatar orientation and conversational turn-taking and describes experiences and lessons from early tests of prototype orthotics.
