The IEEE VR 2014 Workshop on Virtual and Augmented Assistive Technology is intended to bring together technological and clinical research communities to advance the state-of-the-art in Virtual Reality (VR) and Augmented Reality (AR) assistive technology. Over the past several decades, there has been a host of research conducted to improve rehabilitation and enable assistive technology for persons with disabilities (e.g., cognitive, physical) through VR and AR. However, this area needs to take more advantage of state-of-the-art VR and AR technology. We believe this situation could be improved if the two contributing communities to this area - the technology and the clinical communities - had greater opportunity for more direct interaction and collaboration to advance the field. This is the primary goal of this workshop. Specifically, we are inviting submissions of position papers and preliminary research that focus on: novel Virtual and Augmented Reality technologies that could be used to enhance assistive technologies, although they may not have been used for this yet, and insights into and studies involving persons with disabilities and the impact of VR, AR, and associated technologies.
