Dog guide users in Japan were mostly satisfied with and used their dogs frequently; however, they requested some improvements in training and in basic guiding work. The findings of the study suggest the need for further improvement of training methods, considering cultural factors and individual users’ needs.

Attacks by dogs on dog guides are traumatic for dog guide teams. One variable that affects a team's recovery is how handlers cope with emotional responses to the attack. This article presents a three-stage model for assisting handlers that is useful for handlers and dog guide instructors.

Abstract
Eighteen persons with visual impairments evaluated four systematically selected navigation systems. Their performance on 11 tasks, provided ratings, satisfaction on seven aspects of the assistive devices, and explanatory comments show generally valuable functionality and usability, as well as individual marked preferences for various features of different navigation systems.

Abstract
The effectiveness of different types of verbal information provided by electronic travel aids was studied in a real-life setting. Assessments included wayfinding performance and the preferences of 24 visually impaired users. The participants preferred a combination of route information and environmental information, even though this information did not always result in their optimal wayfinding performance.

This article describes and analyzes the development of a navigation and orientation system for people with visual impairments as it evolved over three decades. It includes reflections on how users have been involved in the redesign process and illustrates how people with and without disabilities have collaborated to create a more suitable and accessible transportation system.

Abstract
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.

Abstract
Five cues were evaluated with respect to their usefulness in directing the headings of pedestrians who were blind during street crossings. The study was conducted at a simulated crosswalk, with the angle of the crosswalk varied relative to the approach and direction of the slope of the ramp. Three cues worked well over the distance equivalent to the width of a six-lane road.

Global Positioning Systems’ (GPS) technology is available for individuals with visual impairments to use in wayfinding and address Lowenfeld's “three limitations of blindness.” The considerations and methodologies for teaching GPS usage have developed over time as GPS information and devices have been integrated into orientation and mobility lessons with children, adults, teachers, parents, and orientation and mobility specialists.

The study reported here investigated the design and legibility of tactile thematic maps, focusing on symbolization and the comprehension of spatial patterns on the maps. The results indicate that discriminable and effective tactile thematic maps can be produced using classed data with a microcapsule paper production method. The participants demonstrated that they could describe the spatial data patterns that were displayed.

This study examined which olfactory cues individuals with visual impairments use most often and determined which of these cues these individuals deemed to be the most important for wayfinding in urban environments. It also investigated the ways in which the individuals use these olfactory cues.

The study presented here examined which auditory cues individuals with visual impairments use more frequently and consider to be the most important for wayfinding in urban environments. It also investigated the ways in which these individuals use the most significant auditory cues.

Abstract
A model of vision rehabilitation that assumes that functional ability will affect the emotional and psychosocial adjustment of older persons with visual impairments, and ultimately their quality of life, was assessed using structured equation modeling. The proposed model was upheld. In addition, the ability to get around was found to contribute to both functional ability and quality of life.
