Measurements of height of cane hand, cane length, step size, and forearm length of 17 cane using blind (14-21 years old) Ss were taken for the purpose of testing the hypothesis that the touch technique does not provide 100 percent path coverage. (Author)

The timbre of various Sonicguide (an ultar-sonic binaural device mounted in a spectacle frame) signals was measured and analyzed by a "Sona-Graph" (sound spectral analyzer) to aid/mobility training of blind Ss. (Author/MH)

In the study, eight random samples of respondents (236 adult Ss) from a small Western city were presented with questionnaires which requested that they evaluate the characteristics of a stimulus person who varied by sightedness (blind, totally sightless, partially sighted, sighted), and age (35 or 65 years).

The Tactile Diagrams Research Project at Loughborough University of Technology (England) developed 164 tactile diagrams for teaching 22 biological themes to blind students. Evaluation of the diagrams found most to be effective when properly introduced to students, and used with supporting text or tapes. (CB)

An indexing cassette reference system was developed and subjected to a field trial in which 24 legally blind students from grades 7-12 were taught to use it and then tested on their skill at locating entries in a recorded sample from an encyclopedia. (Author)
