The Internet gives access for blind and visually impaired users to previously unobtainable information via Braille or speech synthesis interpretation. This paper looks at how three search engines, AltaVista, Yahoo! and Infoseek presented their information to a small group of visually impaired and blind users and how accessible individual Internet pages are. Two participants had varying levels of partial sight and two Subjects were blind and solely reliant on speech synthesis output. Subjects were asked for feedback on interface design at various stages of their search and any problems they encountered were noted. The barriers to access that were found appear to come about by lack of knowledge and thought by the page designers themselves. An accessible page does not have to be dull. By adhering to simple guidelines, visually impaired users would be able to access information more effectively than would otherwise be possible. Visually disabled people would also have the same opportunity to access knowledge as their sighted colleagues.

This paper aims to investigate accessibility and usage of mobile smartphones by Arabic-speaking visually impaired people in Saudi Arabia.

In total, 104 participants with visual impairments were interviewed about their use of mobile phones with the following questions: What is the most commonly used mobile phone? What is the popular domain for which they use mobile phones? What are their favorite applications? What accessibility challenges do they usually face while using mobile phones? How often do they use the Internet via mobile phones and what are the reasons behind that?

This research is the first study with such magnitude to investigate smartphone usage by Arabic-speaking visually impaired people. The survey has revealed that Arabic-speaking visually impaired people utilize mobile phones in different ways and strategies. Getting assistance in performing daily tasks and navigating independently are two of the most common uses for mobile phones.

Based on the findings, the authors are going to propose some guidelines to developers to improve smartphone accessibility, application design and Internet usage to improve accessibility for visually impaired people.

This article aims to explore the possibilities and use of a mobile technology‐supported audio annotation system that can be used for attaching free‐formatted audio annotations to physical objects. The solution can help visually impaired people to identify objects and associate additional information with these objects.

A human‐centred design approach was adopted in the system's development and potential end‐users were involved in the development process. In order to evaluate the emerging use cases, as well as the usefulness and usability of the application, a qualitative field trial was conducted with ten visually impaired or blind users.

The findings show that visually impaired users learned to use the application easily and found it easy and robust to use. Most users responded positively towards the idea of tagging items with their own voice messages. Some users found the technology very useful and saw many possibilities for using it in the future. The most common targets for tagging were food items; however, some users had difficulties in integrating the solution with their everyday practices.

This paper presents an innovative mobile phone application with a touch and audio user interface. The actual use cases describe the everyday needs of visually impaired people and this information might be valuable to service providers and technology developers. Also, the experiences gained from these trials can be used when developing software for the visually impaired on other platforms.

The purpose of this paper is to describe recent progress on the “Crosswatch” project, a smartphone‐based system developed for providing guidance to blind and visually impaired travelers at traffic intersections. Building on past work on Crosswatch functionality to help the user achieve proper alignment with the crosswalk and read the status of walk lights to know when it is time to cross, the authors outline the directions Crosswatch is now taking to help realize its potential for becoming a practical system: namely, augmenting computer vision with other information sources, including geographic information systems (GIS) and sensor data, and inferring the user's location much more precisely than is possible through GPS alone, to provide a much larger range of information about traffic intersections to the pedestrian.

The paper summarizes past progress on Crosswatch and describes details about the development of new Crosswatch functionalities. One such functionality, which is required for determination of the user's precise location, is studied in detail, including the design of a suitable user interface to support this functionality and preliminary tests of this interface with visually impaired volunteer subjects.

The results of the tests of the new Crosswatch functionality demonstrate that the functionality is feasible in that it is usable by visually impaired persons.

While the tests that were conducted of the new Crosswatch functionality are preliminary, the results of the tests have suggested several possible improvements, to be explored in the future.

The results described in this paper suggest that the necessary technologies used by the Crosswatch system are rapidly maturing, implying that the system has an excellent chance of becoming practical in the near future.

The paper addresses an innovative solution to a key problem faced by blind and visually impaired travelers, which has the potential to greatly improve independent travel for these individuals.

This study aims to develop a ubiquitous library for the visually impaired (ULVI) application (app) and to explore its usability by collecting feedback from visually impaired participants to analyse the problems they might encounter. Their suggestions for improving the app further are also reported.

A total of ten participants were recruited in the study. Ten tasks were assigned for the participants to complete using the ULVI app. The system usability scale was adopted to collect feedback on the app, and interviews were conducted to understand the participants’ usage behaviours and perceptions of the app.

The findings indicated that the participants provided positive evaluation of the usability of the app and addressed the functions that might need improvement. Above all, this app was regarded as having great potential. Suggestions and improvements are proposed based on the participants’ feedback.

In terms of the studies relevant to libraries and the visually impaired, few have evaluated the usability of the ULVI app from the perspectives of the visually impaired users. The ULVI app provides resources for the visually impaired and serves as the foundation for developing a more effective ULVI app.

This study aims to comprehend the perceptions of visually impaired users in development of information systems in Indian universities. This will help higher educational institutions in India to fulfil information requirements of visually impaired users.

A twofold method was used in the study: survey of visually impaired students in four universities; design and development of an online information system for visually impaired (ISVI). A structured questionnaire was used for survey of visually impaired users in Indian universities. The questionnaire with 33 open-ended questions was distributed among 603 visually impaired users and 316 responses were received. Stratified sampling technique was used in data collection. Response rate was 52.4%. The received responses were analysed using Statistical Package for Social Sciences version 19 and presented through tables and figures.

Majority of respondents revealed that lack of content availability in vernacular language, poor information resources access mechanism, less volume of course content and poor maintenance of assistive software(s) and devices and non-standardized e-resources compatible with the assistive software(s) are some major inhibits faced. Majority of respondents revealed that they prefer scribes in examinations because use of assistive technology (AT) is time-consuming. Lack of training and confidence in using AT is another reason for preferring scribes in examinations.

This study was conducted on a limited number of visually impaired uses in Indian universities. Also, the online system ISVI contains a sample collection related to undergraduate courses only.

This study will help Indian universities to identify problems faced by visually impaired users. Findings of the study can help faculty members, decision-makers to understand the perspective of visually impaired. Besides this, the study can also help government agencies in formulating policies. Findings will help in developing robust information resources suiting the needs of visually impaired.

This study developed an online system ISVI (www.isvi.in) suitable to address the requirements of visually impaired students. Furthermore, it can guide policymakers, faculty members and information professionals in developing seamless open access information systems.

People with visual impairment comprise the second high disability population in Hong Kong, but only two existing information centers provide information services for visually impaired people, which is inadequate. Therefore, this study aims to provide a more in-depth understanding of the information services for visually impaired people in Hong Kong.

IAC's main problems include limited collection, inconsistent multiple digital platforms for user access, limited service hours and limited promotion. Some technological suggestions were proposed, which include: expanding its electronic and special collections, establishing a one-stop digital platform, AI-based chatbot for automated caring chats and reference services, and extending its social network marketing.

Scant studies focus on the information services and management of special libraries for visually impaired people, especially in East Asia. On the other hand, there are limited case studies analyzing libraries with value-chain analysis.

A variety of enabling technologies such as synthetic speech, print enlargement on CRT screens, braille printers and displays, and communications technology has made library operations at the American Foundation for the Blind accessible to persons who are blind or visually impaired. INMAGIC software, a versatile database management system, has automated many library functions and has been integrated with other adaptive technologies. In addition to other applications, INMAGIC is used to update and create bibliographies and accession lists in inkprint, large print, or braille formats (with tape cassette versions available on request). Sidebars discuss the Xerox/Kurzweil Personal Reader (KPR); closed circuit television (CCTV); computers with speech; large print enhancements; Inmagic, Inc.—the company; and, in some depth, the functionality of INMAGIC.

This paper presents a novel interface system to aid people with visual impairment to become proficient with operating unfamiliar devices. The system works by adding touch sensors that trigger audio tags to tactile controls. The touch sensors trigger the audio tags before the control is activated.

The paper describes how several devices were enhanced with the new technology, tested and evaluated. Initial informational interviewing with visually impaired people was followed by user studies with blindfolded but visually able people. A final evaluation of the system was conducted by a visually impaired group.

This paper shows that the technology is of benefit to a visually impaired user when using a complex unfamiliar device.

This novel application of touch sensors coupled with audio tags has the potential to benefit visually impaired people. This technology can easily be incorporated into commercial devices. The idea can also be implemented using off the shelf development boards coupled with smart phones.

The paper addresses the importance of clarifying terminology such as visually impaired and related terms before embarking on accessibility studies of electronic information resources in library contexts. Apart from briefly defining accessibility, the paper attempts to address the lack of in-depth definitions of terms such as visually impaired, blind, partially sighted, etc. that has been noted in the literature indexed by two major Library and Information Science (LIS) databases. The purpose of this paper is to offer a basis for selecting participants in studies of accessibility of electronic information resources in library contexts and to put discussions of such studies in context.

Clarification of concepts concerning visual impairment following a literature survey based on searching two major databases in LIS. To put the discussion in context accessibility is also briefly defined.

Although visually impaired and a variety of related terms such as blind, partially sighted, visually disabled, etc. are used in the LIS literature, hardly any attempt is made to define these terms in depth. This can be a serious limitation in web and electronic accessibility evaluations and the selection of participants.

Clearly distinguishing between categories of visually impaired people and the ability of sight of participants is important when selecting participants for studies on accessibility for visually impaired people, e.g. the accessibility evaluation of web sites, digital libraries and other electronic information resources.

The paper can make a contribution to the clarification of terminology essential for the selection of participants in accessibility studies, as well as enriching the literature on accessibility for visually impaired people in the context of LIS.
