The particular aid we used is Leslie Kay’s Trisensor (8) which is patterned after his earlier Binaural Sensory Aid (BSA). The basic principle on which these aids operate is that a small transmitter irrad

Sensory Substitution in Blind Children and Neonatese of spatial sensors in adults, it may seem surprising that there has been any substantial amount of research with blind children and infants. However, as this paper and others in this volume make clear, developmental studies are a major part of current sensory aid research.

Use of Sonar Sensors with Human Infantsago, we subscribed to a widely held belief that those who had never had visual experience lacked to an extraordinary degree the ability to represent space and spatial relations to themselves (26,50,51). Such individuals, it appears, lack adequate concepts of space and geometry. Given the lively new

However, when this transformation involves no direct “understanding” or complex interpretation of the data by the transforming device, the blind user is still faced with the formidable task of perceiving the data in some “analog” (iconic) form, and must extrac
