The adaptation of the binaural sensory aid for use by blind children is discussed in the context of a pilot study carried out with two blind children; one an intellectually competent 6-year-old girl and the other a developmentally delayed 2-112-year-old boy. Both children showed an ability to make rudimentary spatial and object discriminations with the aid and both showed enhanced mobility skills after involvement in a training program. Several key research variables in this type of work are highlighted, primarily the type of training activities to be used, the regularity of aid use, the age at which training begins, and the sensing and display characteristics of the aid to be used.
