Case studies of three hearing-impaired four-year-old children revealed that vibrotactile stimulation aids were effective in teaching speech skills. The aid helped the students become more aware of sounds. (CL)

This article emphasizes the importance of good design of tactile diagrams and careful diagram use with blind children. Early educational experiences are suggested to equip blind children for most effective use of diagrams. Methods for teaching diagram use are also suggested, particularly where blind children are educated in integrated settings.…

The article suggests the use of non-expert sighted volunteers to teach the reading and writing of Moon Script, a tactual system of raised-line characters similar to the Roman alphabet, to visually impaired people. Experimental courses with both blind and sighted volunteers are described. (DB)

Compared was the effectiveness of training in three different tactual map reading search patterns with 144 braille readers in grades 4-12. (LH)

THE PAPER DESCRIBES AUDITORY AND TACTILE ADAPTATION OF PHYSICS LABORATORY APPARATUS FOR USE BY BLIND STUDENTS, TOGETHER WITH FIVE METHODS OF DRAWING RAISED LINE AND INDENTED DIAGRAMS FOR USE IN PHYSICS EXPERIMENTS. A SURVEY OF PHYSICS LABORATORY METHODS IN SCHOOLS FOR THE BLIND IN THE UNITED STATES AND SEVEN FOREIGN COUNTRIES, AND TWO SIMPLE…

An independent engineering evaluation was conducted of the Optical to Tactile Converter (Optacon), a reading aid for the blind which senses the contrast of printed text and converts the information into a tactile presentation. Tasks performed included: user evaluation, optical, electrical, mechanical, production costs, life tests, reliability, and…

Two experimental tactile political map designs were evaluated with 72 blind braille reading students (grades 4-12). (Author/CL)

Thirty-seven blind students (in grades 2, 3, and 4) were involved in a study to evaluate the tactile ruler familiarization unit (three vacuum-formed plastic sheets illustrating English, Metric, and English-Metric measurement units). (SBH)

Introduces new technologies that provide instant translation of print materials in three general categories: optical to tactile conversion of print, optical to braille conversion, and optical to speech. Talking books, voice indexing, new braille technologies, print to braille, and optical print enlargement are highlighted. A list of sources is…

Point and linear symbols that represent certain areas of building interiors are discussed in light of their reliability and discriminability if used on tactual maps. A set of "optimally sized" symbols were evaluated with 21 blind observers. (Author/DB)

Describes an exploratory investigation of blind children's concepts of number, substance, length, area, weight, and volume conservation. Six children totally without sight or with only light perception were pretested, taught, and posttested twice using tasks specifically adapted for tactual presentation of materials. The children showed increased…
