Experiences in the past 25 years in the development of sensory substitutes for the disabled have led the author to the research on the virtual reality by which sensory images are created that approximate what the lost sensory organ would sense but does not actually exist. Findings thus obtained on concept formation, sensory association and other functions of the brain have philosophical implications. The paper presents an overview of a new system of technology that emerges from the virtual reality research.
