Abstract:
An experimental ultrasonic sonar for use as a sensory aid with blind children is described. Novel signal processing techniques make the aid relatively simple to construct, yet allow many of its parameters to be changed in the field. In particular, the aid has two features, a variable range code and an automatic level control, which make the device very versatile in a wide variety of environments. The ultrasonic tranducers used in the aid are described in some detail.

01:23Vision During Infancy and Toddlerhood
At birth, vision is the least developed of the major senses because the visual system is still structurally and neurologically immature. The retinas, optic nerves, and visual regions of the brain continue to mature after birth. As a result, newborns have limited visual acuity, or sharpness and clarity of vision, and respond best to objects viewed at close range, roughly 8 to 12 inches away.Rapid Visual DevelopmentVision improves rapidly during the first few months as infants observe and...
01:30Perceptual Development During Infancy
Perceptual development enables infants to organize and interpret sensory information, helping them understand objects, distances, and surfaces in their environment. Two important aspects are depth perception and haptic perception. These abilities develop as infants gain sensory experience and their nervous systems mature.Development of Depth PerceptionDepth perception is the ability to see objects and surfaces in three dimensions and judge their relative distance. Infants gradually learn to use...
