Introduction: A national validation study on the "Orientation and Mobility Visual Impairment Scale of Service Intensity of Texas (O&M VISSIT)" was conducted. Methods: Fifty-two of the original 115 interested participants completed the study that used a mixed-methods research design. After finishing the "O&M VISSIT" for…

Background: Spatial knowledge about an environment is an important determinant of ability to move effectively within it and of personal autonomy. Individuals with Down's syndrome (DS) have difficulty managing configural visuospatial information. Method: Twenty-nine individuals with DS and 29 typically developing (TD) children, matched for mental…

Introduction: This study analyzed survey responses from 114 orientation and mobility (O&M) specialists regarding the content and procedures they used in completing O&M assessments. Methods: O&M specialists completed an online survey in 2020 on their assessment practices for children and youths who are visually impaired. Results: Over…

This study examined the mental effort required to monitor landmarks and the effect of the type of route on mobility-route training. The results revealed that the features of landmarks and competence in travel were significantly related, indicating that some environmental factors related to height and width are more easily learned when people can…

A panel of 20 experts in orientation and mobility (O&M) reached consensus on concepts and skills that O&M specialists should teach to students who are blind or have low vision. Panelists also agreed on visual, environmental, and behavioral conditions that would require a formal O&M assessment.

Retinitis pigmentosa (RP) causes restriction of the visual field, progressive vision loss, and night blindness. This article presents an overview of the most common problems in orientation and mobility (O&M) for individuals with RP, appropriate interventions, vision science discoveries related to RP, and the impact of RP on functional visual…

In an unfamiliar residential neighborhood, 24 10- and 6-year olds were individually evaluated and compared on their conceptual knowledge of the neighborhood. Findings indicate there are statistical and practical differences between the two age groups. Implications for teaching orientation and mobility to children with low vision are discussed.…

The article discusses the Sonicguide, and electronic mobility device for the blind, and makes some suggestions for its introduction to young children and for its use as an aid in the development of spatial concepts. (Author/DLS)

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…

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)

UNITS, ACTIVITIES, LESSON PLANS, AND RESOURCE MATERIALS TO HELP ELEMENTARY TEACHERS REINFORCE INSTRUCTION IN BASIC PRE-CANE MOBILITY AND ORIENTATION SKILLS ARE PRESENTED. APPENDIXES INCLUDE A DEFINITION OF TERMS, AN ORIENTATION AND MOBILITY CHECKLIST WITH TEACHER INSTRUCTIONS, SUGGESTIONS FOR GUIDING BLIND INDIVIDUALS, AND SUGGESTED SUMMER…

A peripatologist taught 102 blind and partially sighted individuals of all ages mobility and orientation techniques. Volunteers assisted with transportation, followup, consultation, and direct teaching of mobility. Over a 3-year period, the number of lessons per client varied from one to 86, and the number of hours spent by the instructor in…

Discusses using the Timing Method for Assessing the Detection of Vehicles (TMAD) to help individuals with visual impairments develop the ability to judge their safety for crossing streets with no traffic control. Functional criteria for assessing risks are discussed. (CR)

A survey of orientation and mobility specialists (N=26) was conducted to determine the mobility devices currently being used with visually impaired and elderly clients. These results were then used to design and develop an effective, commercially manufacturable adaptive-mobility device prototype which was tested with elderly individuals, multiply…

This fact sheet about students who are deaf-blind provides information on orientation and mobility (O&M) training. It begins by describing orientation and mobility skills, and emphasizes the need for a team approach in the development and implementation of O&M instruction. Instructional strategies are described, including initial assessment of O&M…
