There is an alarming increase in more Singaporean children diagnosed with special needs and it could be attributed to higher awareness and better screening procedure. However, research and development on various intervention strategies for children with special needs is still very lacking. With the introduction of information and communication technology, a wide range of useful intervention tools are now available to both special education professionals and parents with disabled children. In particular, interest in virtual reality (VR) within the domain of special education community is on the rise as reflected in a growing number of special issues of journals on this subject. VR offers a new channel to reach out to individuals with special needs such as cerebral palsy and autism. However, its effectiveness in intervention for such individuals has not been fully explored. In this paper, the authors have collaborated with a research team of the Pink Dolphin Simulation project at the Institute for Media Innovation, Singapore, to design a generic questionnaire for VR researchers and special education professionals to use in evaluating reflectively the possible benefits a VR-based intervention can offer. In this case, the VR-based intervention using the specially designed virtual dolphins was used for reflective evaluation. (Contains 4 figures.)
