This report attempts to define the telecommunications requirements and support services needed by mentally retarded users in Sweden. It focuses on population, definitions, and classifications of mental retardation, and implications of mental retardation in daily living. Support services including medical care, habilitation, and education for people with mental retardation are also discussed. The importance of communication for people with mental retardation is emphasized and a plan to pilot the use of videotelephones for this population is presented. For this effort, client characteristics, benefits, equipment and network requirements, service classification, and service procedures and staffing are considered. (Contains 20 references.) (DB)
