Virtual reality (VR) describes a set of technologies that allow users to explore and experience 3-dimensional computer-generated "worlds" or "environments." These virtual environments can contain representations of real or imaginary objects on a small or large scale (from modeling of molecular structures to buildings, streets, and scenery of a…

The importance of sound instructional design and planning is stressed in this article on the application of hypermedia to intervention with language handicapped children. Hypermedia is defined, its applications on various microcomputers are described, features for speech-language applications are identified, and a model for instructional…

Through case studies, this article examines how technology can be used as part of intervention strategies with language handicapped children. It discusses theoretical considerations; stimuli, responses, and reinforcements; staff roles; individualization; and software. The need for increased accessibility to computers by speech/language clinicians…

This article describes an evolution of training programs to use first-person interaction in virtual reality (VR) situations to teach safety skills to children with autism spectrum disorder (ASD) and fetal alcohol spectrum disorder (FASD). Multiple VR programs for children aged 2 to 9 were built and tested between 1992 and 2007. Based on these…

The article explains the role of feedback and biofeedback in speech therapy; identifies speech parameters that can be modeled by current systems (e.g., pitch, intensity, voice quality, and articulatory accuracy); and describes selected microcomputer-based speech production biofeedback systems that are available. An appendix provides sources. (DB)
