Accessible pedestrian signal was proposed as a mean to achieve the same level of service that is set forth by the Americans with Disabilities Act for the visually impaired. One of the major issues of existing accessible pedestrian signals is the failure to deliver adequate crossing information for the visually impaired. This article presents a mobile-based accessible pedestrian signal application, namely, Virtual Guide Dog. Integrating intersection information and onboard sensors (e.g. GPS… 
Inertial Measurement Unit Sensors in Assistive Technologies for Visually Impaired People, a Review
The aim of this work was to present a comprehensive approach of assistive technologies for VIP that include inertial sensors as input, producing results on the comprehension of technical characteristics of the inertIAL sensors, the methodologies applied, and their specific role in each developed system.


Using a Smartphone Application to Support Visually Impaired Pedestrians at Signalized Intersection Crossings
Objective and subjective measures were developed to evaluate the performance of visually impaired users of MAPS to identify whether the smartphone application could effectively provide geometry and signal timing information and thus provide decision support for visually impaired pedestrians.
Accessible Pedestrian Signals
The U.S. Access Board's Draft Guidelines for Accessible Public Rights-of-Way recommends the use of push-button-integrated accessible pedestrian signals (APSs). This research compared the effect of
Integrated online localization and navigation for people with visual impairments using smart phones
A system able to guide people with VI through buildings using inexpensive sensors, such as accelerometers, which are available in portable devices like smart phones, which is executed online on a smart phone.
Accessible Pedestrian Signals Effect of Device Features
The U.S. Access Board's Draft Guidelines for Accessible Public Rights-of-Way recommends the use of push-button-integrated accessible pedestrian signals (APSs). This research compared the effect of
Wearable Smart System for Visually Impaired People
A wearable smart system to help visually impaired persons (VIPs) walk by themselves through the streets, navigate in public places, and seek assistance, which has more features than other similar systems and is expected to be a useful tool to improve the quality of life of VIPs.
An Intersection Database Facilitates Access to Complex Signalized Intersections for Pedestrians with Vision Disabilities
This project investigated the effects of providing verbal descriptions of intersections and crosswalks on the performance of street-crossing subtasks by individuals who are totally blind and designed an intersection database containing information relevant to crossing subtasks.
Towards an Accessible City: Empirical Measurement and Modeling of Access to Urban Opportunities for those with Vision Impairments, Using Remote Infrared Audible Signage
This paper examines the problems of defining and measuring access for blind travelers in an urban transit environment. Current accessibility measures do little to account for individual differences
SWAN: System for Wearable Audio Navigation
A system for wearable audio navigation (SWAN) is being developed to serve as a navigation and orientation aid for persons temporarily or permanently visually impaired.
Better Supporting Blind Pedestrians and Blind Navigation Technologies Through Accessible Architecture
The ways that architecture both aids and hinders blind pedestrian navigation are expounded and a case for collaborations between technologists and architects (especially those focused on accessible architecture) is made.
Lightweight smart glass system with audio aid for visually impaired people
A new smart glass system for people who are blind or have low vision that can see the world for them and give voice instructions and hints through wireless bone conduction headphones and an application of public signs recognition on the smartGlass system.
