This article reports on a method for calculating the space-saving capacity of all Grade 2 braille contractions and the literary braille code as a whole. The study found that, contrary to the widespread belief that contracted braille saves 31% over print, the actual text reduction is about 20%. (Author)

A cell-by-cell analysis of finger movements of 16 blind adolescent braille readers was conducted to separate, catalog, and measure the components of scanning movements across braille cells as a function of reading proficiency. Results confirmed the superiority of bimanual reading and suggested that the two hands may perform different functions.…

This study evaluated performance of blind (n=17) and sighted adults on a haptic numerosity task of braille symbols in which symbol size was varied. Although blind subjects performed better than seeing subjects, the rate of learning and patterns of errors were similar, except that blind subjects did better with standard than with enlarged symbols.…

This study of 12 individuals with blindness or low vision extended earlier studies by Morton Heller concerning speed and accuracy of reading noncanonical (tilted) braille text. Results were similar for Heller's original character set (B-J), but the effect of orientation was reduced with other letters and whole words, especially for experienced…

Two word/nonword decision experiments were carried out to investigate differences in reading between congenitally blind children reading Braille and sighted children dealing with print. Three aspects of single-word recognition were studied: semantic processing, word frequency effects, and phonological recoding. (Author/RH)

Eleven basic types of visually displayed information that can be, and should be, rendered accessible to the visually impaired user are discussed. Speech, braille, and tactile technology are addressed as well as the innovative technique of "haptic-tactic" display combining a raised dynamic image of the screen's page with speech. (Author/DB)

Describes a project at Chorleywood College (England) which examined the possibility of automating the transcription of braille examination responses for marking by examination boards. Discussion covers the braille code, requirements of the transcription system, an analysis of mock examination papers which led to system modification, and the final…

Analysis of completed surveys from 230 teachers of blind and visually impaired learners found that preservice training programs emphasizing the methodology of teaching Braille and the development of tactual perception tended to produce teachers who have positive attitudes toward Braille and feel competent in teaching Braille to children.

To test the validity of the National Literary Braille Competency Test (NLBCT), 181 Florida teachers of students with visual impairments were asked if they transcribe Braille using a Braillewriter, a slate and stylus, Braille computer programs, or transcriber aides. The majority transcribed using computer software or a Braillewriter. (CR)
