This study compared the observational skills in orientation and mobility (O&M) of nine university students and nine certified O&M specialists using a digital video assessment. The students differed from the O&M specialists in their stylistic observations and the details of their responses. Implications for the improvement of video assessments are…

Electronic travel devices are used to transform information about the environment that would normally be perceived through the visual sense into a form that can be perceived by people who are blind or have low vision through another sense (Blasch, Long, & Griffin-Shirley, 1989). They are divided into two broad categories: primary devices and…

This is the final part of the adaptation from my on-stage conversation with Russell Williams at the 1998 International Mobility conference in Atlanta, GA, which attempted to highlight Williams's contributions to the progression of orientation and mobility from the Army's immediate response to the service men and women who lost their sight during…

The authors interviewed and videotaped diabetic adults with visual impairments about their perceptions of orientation and mobility (O&M) services that they had received. The visual impairments of these middle-aged adults ranged from totally blind to low vision. The interview questions focused on demographic information about the interviewees, the…

This report was released by the National Center for Special Education Research (NCSER) on January 23, 2008. Orientation refers to one's ability to determine his/her location and relationship with other objects in the environment. Mobility refers to one's ability to move about in the environment. Orientation and mobility training may be provided to…

A portable control device linked via radio to acoustic sources was used for prompting independent travel and activity in two adolescents with severe multiple disabilities. The device allowed the subjects to enter activity destinations with a simple, standard response, which activated acoustic sources that indicated the way to each destination.…

A study investigated the number of guide dog teams that have been trained and are active in the United States from 1993-1999. Results found 1,556 guide dog teams were trained in 1999, an increase of 7%, and that there were 9,000 active teams, an increase of 10% since 1993. (Contains eight references.) (CR)

This paper describes meetings by a panel of travel, access, and public transit professionals to discuss detectable warning systems (devices to notify individuals with visual impairments of hazards along their path of travel). Recommendations of the panel for universal design standards and educating communities about detectable warning systems are…

This article discusses how orientation and mobility instructors can provide direct sensory experience about many concepts that can effect meaningfully positive changes in the understanding and subsequent language development of children with visual impairments. It provides recommendations to enhance the linguistic knowledge and vocabulary…

This article reports on the ability of observers who are sighted and those with low vision to make time-to-collision (TTC) estimations using video. The TTC estimations made by the observers with low vision were comparable to those made by the sighted observers, and both groups made underestimation errors that were similar to those that were…

Twenty-six children (ages 6-11) with visual impairments were given tactile maps and asked to locate themselves on the map as they walked a short route. On 75% of the trials the children indicated their positions accurately, and on 81% they identified the routes they had traveled. (CR)

This article reviews developmental and neuropsychological evidence of differences between modes of processing small-scale and large-scale spatial information, and discusses implications for teaching students with visual impairments. Understanding of developmental processes is felt to be the key to diagnosing and treating orientation and mobility…

This article presents a literature survey and conceptual model of the perceptual-motor performance of children with visual impairment, in relation to their social development. The relationships between visual impairment and orientation, visual impairment and mobility, and motor performance and social integration are examined. (Author/SW)

A survey of 120 orientation and mobility instructors found that 75% have taught their students to use alternative mobility devices. The type of device taught most often was a two-shafted device (such as the Connecticut precane). Other devices included riding toys, upright push toys, and probing devices. (Author/CR)

This study evaluated descriptions, either from memory or by using a map (print or tactile), of 12 visually impaired and 12 sighted elementary grade children of two routes around their schools. Descriptions from maps were generally poorer than those from memory. Qualitative differences were also found between descriptions of visually impaired and…
