Thirty randomly selected, low vision patients were evaluated on their performance in viewing a standard near-point chart and selected materials without any vision aids, then with their customary low vision aid handheld, and finally, with their customary low vision aid viewed in an optiscope enlarger.

The studies involving two blind adults evaluated a new system-- Trigemina--that relates visual information to blind persons by tactile stimulation through a matrix of 10 x 10 vibrating rods applied to a postage stamp-sized area of skin over the forehead. (Author/SBH)

Preliminary results indicated that the binaural sensory aid is useful within a regular program of developmental intervention, but that positive effects cannot be attributed to the device alone. (Author/DLS)

The study demonstrates that, with a brief training period, deaf adolescents (N=8) can attain a high level of perceptual performance with a tactual speech system in discrimination of certain hard to lipread word pairs pronounced by both a male and a female speaker. (Author/SBH)

Described is a program of research into sensory aids for the deaf, emphasizing research on factors involved in the effective use of sensory aids rather than evaluation of particular devices. Aspects of the program are the development of a programed testing and training unit, the control of fundamental voice frequency using visual feedback, and…

In a study investigating the use of a talking calculator as a computational aid with nine blind children in grade 3 through grade 8, it was found that Ss could benefit from the aid of a talking calculator in their curricular mathematics when there was need for a fast, accurate, and portable aid to mathematical computation.

The author, who is congenitally blind, describes two training programs with a Tactile Vision Substitution System, including a mobile version of the device. (Author)

The authors describe the function of a low vision clinic and report on an evaluation of one clinic's services. (Author)

A remotely activated tactual communication aid is described, and results obtained from tests with the aid on five normal hearing young adults and five profoundly hearing impaired children (8 to 14 years old) are reported. (SBH)

Presented is a report on the 5-year project to develop the Optacon, an electronic device which allows the blind individual to read ordinary printed matter directly and independently. Chapter (1) provides and introduction and overview of the Optacon Project. Summarized in Chapter (2) is a chronological account of the Optacon Project which traces…

To investigate impaired residual disciminiation for low-frequency formants and its influence on electronic compensation effectiveness, evaluations were made on impaired discrimination for speech formants, synthetic enhancement of consonants, wearable transposer aids, and a speech perception survey. Results showed that certain persons with severe…
