Introduction: The study presented here examines which haptic cues individuals with visual impairments use more frequently and determines which of these cues are deemed by these individuals to be the most important for way-finding in urban environments. It also investigates the ways in which these haptic cues are used by individuals with visual…

Orientation and mobility (O&M) practice is important because the population of persons with visual impairments is large enough to warrant planned action on measures to help them acquire independence and sustain their livelihoods. Most O&M practitioners in South Africa are full-time employees in non-governmental organizations. The few who…

Echolocation is a specialized application of spatial hearing that uses reflected auditory information to localize objects and represent the external environment. Although it has been documented extensively in nonhuman species, such as bats and dolphins, its use by some persons who are blind as a navigation and object-identification aid has…

Introduction: The BlindAid, a virtual system developed for orientation and mobility (O&M) training of people who are blind or have low vision, allows interaction with different virtual components (structures and objects) via auditory and haptic feedback. This research examined if and how the BlindAid that was integrated within an O&M…

Introduction: Youths with visual impairments attend postsecondary school at high rates, yet these individuals have low rates of employment. In this study, factors associated with post-school employment were investigated in a nationally representative sample of youths with visual impairments. Methods: In a secondary analysis of data from the…

Truncated domes on curb ramps benefit travelers with visual impairments. However, concerns associated with the safety and negotiability of such detectable warnings for other travelers have resulted in much controversy. The findings of the study presented here indicate that detectable warnings did not adversely affect the negotiability of ramps by…

Introduction: Development of a sensing device that can provide a sufficient perceptual substrate for persons with visual impairments to orient themselves and travel confidently has been a persistent rehabilitation technology goal, with the user interface posing a significant challenge. In the study presented here, we enlist the advice and ideas of…

Introduction: In this study, executive function of school-aged children with visual impairments (that is, those who are blind or have low vision) is examined in the context of behavioral problems and communicative competence. Methods: Teachers assessed the executive function of a sample of 226 visually impaired students from mainstream schools and…

Accessible Global Positioning Systems (GPS) are changing the way many people with visual impairments (that is, those who are blind or have low vision) travel. GPS provides real-time orientation information so that a traveler with a visual impairment can make informed decisions about path of travel and destination. Orientation and mobility (O&M)…

Research indicates that children with visual impairments demonstrate delays in fundamental motor skills, including locomotor, object control, and balance skills (Haibach, Lieberman, & Pritchett, 2011; Houwen, Hartman, & Visscher, 2010; Wagner, Haibach, & Lieberman, 2013). All of these skills are prerequisites to living an independent…

This study examined the interaction effects of the amount of practice and the cane technique used in drop-off detection with a sample of 32 adults who were blind. The advantage of the constant contact technique over the two-point touch technique was significantly greater for the less experienced cane users than for the more experienced ones.…

Introduction: This article discusses the impact of blindness and low vision on the development of object permanence and provides suggestions for assessment and instruction. Methods: The reviewed literature was identified by searching both ERIC and Psych Info using combinations of search terms such as "object permanence" and "visual…

Participants who are blind discriminated vehicle paths and made crossing decisions for hybrid vehicles with and without artificial sounds added. Several artificial sounds matched the performance of tasks observed with vehicles with internal combustion engines. These data, with previous vehicle-detection results, indicate that selecting artificial…

The number of visually impaired people is increasing year by year. Although attention has been given to the needs of people with disabilities, most of the discussion has focused on social welfare, while talk about assistive technology for people with disabilities is rare. The blind need training courses for reconstruction and rehabilitation.…

Accurately aligning to a crosswalk is an important component of safe street crossing for pedestrians who are blind. Six alignment cues were evaluated in a simulated crosswalk environment in which the angle of the crosswalk was not always in line with the slope of the ramp. The effectiveness of each cue is reported and implications are discussed.…
