An increasing body of literature demonstrates the effectiveness of interventions involving speech-generating devices (SGD) for children with autism with limited vocal speech output abilities. Few studies have evaluated interventions that teach children to "travel" to the device before making requests. The current study evaluated a…

Introduction: To better serve students with visual impairments who are enrolled in personnel preparation programs training orientation and mobility (O&M) specialists, faculty should be aware of effective teaching strategies, tools, and resources to use. In this context, it is vital that instructors in personnel preparation programs for O&M…

Introduction: Individuals with visual impairments may use long canes for estimating distances and detecting gaps, obstacles, and texture patterns. The study presented here investigated whether length perception with canes is influenced by cane material. Methods: Visually impaired, sightedblindfolded, and sighted individuals (n = 30 for each group)…

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…

Introduction: The purpose of this study was to survey the faculty of personnel preparation programs that train orientation and mobility (O&M) specialists in the identification of accommodations, teaching techniques, and resources needed to teach students who are visually impaired (i.e., those who are blind or have low vision) and who are…

Background: This study extended the assessment of a technology-aided orientation program with auditory cues by including 2 participants with multiple disabilities who had difficulties in indoor travel and showed travel-related anxiety behaviours (e.g., calling for help and whimpering). Method: The study was carried out according to a multiple…

Although individuals who are blind have used a stick or a cane for their independent travel since the early years of human history, designs for modern long canes did not appear until World War II, when the systematic long cane techniques were developed by Hoover (1962). Ergonomic factors, such as the length of the cane, may affect how well a cane…

This study was an effort to extend the evaluation of orientation technology for promoting independent indoor traveling in persons with multiple disabilities. Two participants (adults) were included, who were to travel to activity destinations within occupational settings. The orientation system involved (a) cueing sources only at the destinations…

These two studies assessed adapted orientation technology for promoting correct direction and room identification during indoor traveling by persons with multiple (e.g., sensory, motor and intellectual/adaptive) disabilities. In Study I, two adults were included who had severe visual impairment or total blindness and deafness and used a wheelchair…

This study compared the drop-off detection performance with the two-point touch and constant contact cane techniques using a repeated-measures design with a convenience sample of 15 cane users with visual impairments. The constant contact technique was superior to the two-point touch technique in the drop-off detection rate and the 50% detection…

Persons with profound visual impairments and other disabilities, such as neuromotor and intellectual disabilities, may encounter serious orientation and mobility problems even in familiar indoor environments, such as their homes. Teaching these persons to develop maps of their daily environment, using miniature replicas of the areas or some…

Orientation and wayfinding are critical skills for successful mobility of people with visual impairments. The inability to perform these skills successfully may result in a person becoming lost, injured, and discouraged from further mobility. At times, it may be impossible to maintain orientation. The person may temporarily travel without cues…

Persons who are deaf-blind represent a heterogeneous, low-incidence population of children and adults who, at some point in life, regardless of the presence of additional disabilities, may benefit from formal orientation and mobility (O&M) instruction. Current national policies, such as the No Child Left Behind Act, which emphasize that…
