Introduction: Many tactile graphics designed for individuals with visual impairments consider single factors. According to the results of our previous study, there may be interactions among scale, representation, and complexity factors. We conducted this integrative study with these three factors. Additionally, for the representation factor, we…

The promise of novel technological strategies and solutions to assist persons with visual impairments (that is, those who are blind or have low vision) is frequently discussed and held to be widely beneficial in countless applications and daily activities. One such approach involving a tactile-vision sensory substitution modality as a mechanism to…

Audio description (AD) has been introduced as one solution for providing people who are blind or have low vision with access to live theatre, film and television content. However, there is little research to inform the process, user preferences and presentation style. We present a study of a single live audio-described performance of Hart House…

Diagram describing texts are integral part of science and engineering subjects including geometry, physics, engineering drawing, etc. In order to understand such text, one, at first, tries to draw or perceive the underlying diagram. For perception of the blind students such diagrams need to be drawn in some non-visual accessible form like tactile…

Faculty Shortages in the study of low-incidence sensory disabilities (deafness, blindness, deaf-blindness) constitute personnel preparation challenges, as documented by a variety of organizations. To alleviate this deficit in the low-incidence sensory disability professoriat, the National Leadership Consortium for Sensory Disabilities (NLCSD) was…

To take a physics course blind students must be assisted using teaching methods and aids adapted to their own perception capabilities. Touchable objects are very important for them because they have huge difficulties to visualize the third spatial dimension. However, appropriate resources and methods for blind students are not yet available. In…

In order to investigate the effect of concurrent phoning and auditory environmental monitoring, the performance of visually impaired people was observed on a dual task that consisted of two simulation tasks. Subjects wore either a bone conducting headset, or closed or open (air conduction) earphones. Reaction times and the correctness of responses…

Four blind children aged 10-30 months received training in the use of the Binaural Sensory Aid, adapted for use by children. Although the two youngest children learned to use the aid, the two older children showed substantially less ability to respond to information provided by the aid. (Author/CL)

The study investigated the use of ultrasonic sonar device--the Sonicguide--by 10 blind infants. Noted among findings is that the use in the younger infants is more rapid and spontaneous. (Author/SB)

Systematic instruction in reading music with the Optacon was given to seven blind Optacon users (10-24 years old) with musical training. (Author/SW)

Article detailed the efforts of Recording for the Blind, Inc., a voluntary organization that supplies growing numbers of blind students, free of charge, with accurate tape recordings of any textbooks their studies require. (Author/RK)

The guide updates one section of a previously written manual on speech software for blind and visually impaired persons. The guide presents reviews of 14 specific commercially available software programs. Software is critiqued for IBM (Enhanced PC Talking Program, Soft Vert, Screen-Talk Pro, Artic Vision, Freedom 1, and Prompt-Writer), Apple…

A blind infant used the Canterbury Child's Aid (a binaural spatial sensor) for such purposes as reaching, feeding, and walking. As a preschooler, she used it to explore novel environments and avoid objects in her path. Training increased her responsiveness to and action upon the environment. (CL)

An evaluation of five voice calculators now on the market--the Canon SP-1260-D, Panasonic JE-165OU and JE-72OU, Sharp EL-620, and Speech Plus--by 20 legally blind adults indicated that most can easily by used by visually handicapped people. Descriptive information is given. (Author/MC)
