Key Features

This paper introduces a novel travel for blind users that can assist them to detects location of doors in corridors and also give information about location of stairs. The developed system uses camera to capture images in front of the user. Feature extraction algorithm is used to extract key features that distinguish doors and stairs from other structures observed in indoor environments. This information is then conveyed to the user using simple auditory feedback. The mobility aid was validated on 50 visually impaired users. The subjects walked in a controlled test environment. The accuracy of the device to help the user detect doors and stairs was determined. The results obtained were satisfactory and the device has the potential for use in standalone mode for indoor navigations.

Source Of Information

This research is a study on improving information facilitated by common GPS based mobile application for navigation especially by the blind users. For a blind person, the main source of information is words and how to improve the effectiveness of the explanation using mobile application for them is tested in this research. The long term goal of technology is to create a movable, self-contained system that allows visually impaired people to navigate through unfamiliar environments without the assistance of guides The experiment for the research took place at MFB (Malaysian Foundation for the Blind) using existing GPS based mobile applications and the results were used to prove the hypothesis that the blind are at a considerable downside because of the absence of information and providing a detailed description of the environment could be used in the GPS navigation applications for the blind pedestrians to help them navigate independently and it would enable them to take up GPS for independent navigation in unknown environment. The information derived from the research could further help in creating and improving the semantics of the GPS based navigation technology for the blind pedestrians in an unknown environment.

The Relationship

Researchers have discovered significant faults in the accessibility of university websites, especially for visually-impaired users. To determine the requirements for totally blind users, this study conducted a comprehensive literature review and accessibility evaluation on 15 Palestinian university websites. The determined factors were used in designing an accessible web page prototype. An online questionnaire was constructed to evaluate the accessibility of the prototype from the blind users’ perspective. From the evaluation of 16 blind participants, it was found that the prototype was highly accessible (mean score 4.19). The regression analysis test was utilised to determine the relationship between the items and the main principles of accessibility. The results show that there are statistically significant differences between these items. In conclusion, the accessibility factors have been indirectly validated.

Abstract: Two sets of nonbraille elevator symbols were compared to determine which set would be most appropriate for visually impaired and blind users of public elevators in California. One set was designed under the sponsorship of the California Alliance of Blind Students (CABS); the other was designed by the National Elevator Industry, Inc. (NEII). Both contained symbols for the “open door,” “close door,” and “emergency stop” commands on an elevator operating panel. After learning the symbols, 62 visually handicapped volunteers deciphered the symbols in a series of random trials. The results indicated that the CABS symbols could be identified more rapidly and accurately than the NEII symbols.

This chapter covers the guidelines developers should follow when creating mobile applications to support visually impaired people in their use of public transports. Technology has evolved in a remarkable fashion, mobile applications being the perfect example of a resource that has been solving problems for a vast array of users, including visually impaired people. These apps hold tremendous potential seeing as they present an accessible, multi-functioned, and cost-effective solution to the mobility issues impacting visually impaired people. In order to identify the best practices in the development of these apps, one should focus on the particularities, limitations, and concerns of visually impaired people regarding their mobility, orientation, and navigation on public transports. It's equally important to understand the existing technology and how these users interact with it, so that we can optimize the user experience, the accessibility, and usability in future endeavors.
