Teleworking is an everyday reality in today’s world. Many companies are opting for this way of working remotely, as it improves employers’ satisfaction along with the work–life balance and it does not lead to any significant reduction in performance. In general, the comfortable use of software applications is a priority, and quality aspects such as usability are of vital importance. In this paper, a novel workflow is proposed. It consists of the following components: (1) a tool to manage usability evaluations based on expert reviews, called Usevalia; (2) a set of heuristics to be considered when performing the evaluations; (3) a catalogue of usability requirements to guide the evaluations; (4) a checklist related to the heuristics to verify that the evaluations have been performed correctly by all the auditors; and (5) a set of tasks to know in advance the functionality of the applications to be audited. Personal health records (PHRs) were taken as a case study. This methodology made it possible to involve a total of 31 working groups that evaluated the usability of four PHRs. Concerning the main results, the evaluators agreed that with Usevalia the usability evaluations could go a step further because they are coordinated and can work together remotely. In addition, analyses of usability scores provided insight into current proposals for improving usability of applications.

“…In general, there is a significant lack of research focused on analyzing accessibility barriers and adequate technical solutions to guarantee accessibility for people with low vision (Moreno et al , 2020). The fact that many of these people can function independently despite certain limitations, without the help of white canes or guide dogs, makes them go unnoticed on a day-to-day basis.…”

“…On the other hand, in recent years other resources have also been published aimed at collecting accessibility requirements for people with low vision, including some relevant to statistical charts. This is the case of the accessibility requirements for people with low vision published by the Low Vision Task Force of the W3C (Allan et al , 2019), the compilation of adaptation techniques for this same user profile by Moreno et al (2020) or Van Achterberg (2019). In the same vein, but with a more practical orientation, Sorge (2020) has delved into the accessibility not only of statistical charts, but also of the remainder of STEM documents (Sorge et al , 2020) due to its importance in guaranteeing students' access to these subjects under equal conditions.…”

PurposeStatistical charts are an essential source of information in academic papers. Charts have an important role in conveying, clarifying and simplifying the research results provided by the authors, but they present some accessibility barriers for people with low vision. This article aims to evaluate the accessibility of the statistical charts published in the library and information science (LIS) journals with the greatest impact factor.Design/methodology/approachA list of heuristic indicators developed by the authors has been used to assess the accessibility of statistical charts for people with low vision. The heuristics have been applied to a sample of charts from 2019 issues of ten LIS journals with the highest impact factor according to the ranking of the JCR.FindingsThe current practices of image submission do not follow the basic recommended guidelines on accessibility like color contrast or the use of textual alternatives. On the other hand, some incongruities between the technical suggestions of image submission and their application in analyzed charts also emerged. The main problems identified are: poor text alternatives, insufficient contrast ratio between adjacent colors and the inexistence of customization options. Authoring tools do not help authors to fulfill these requirements.Research limitations/implicationsThe sample is not very extensive; nonetheless, it is representative of common practices and the most frequent accessibility problems in this context.Social implicationsThe heuristics proposed are a good starting point to generate guidelines for authors when preparing their papers for publication and to guide journal publishers in creating accessible documents. Low-vision users, a highly prevalent condition, will benefit from the improvements.Originality/valueThe results of this research provide key insights into low-vision accessibility barriers, not considered in previous literature and can be a starting point for their solution.

“…That is not to say, of course, that no noteworthy advances have been made in recent years, and one of the most successful pushes towards accessibility has come through the ever increasing adoption of smart phones, devices that can be used as capable accessibility tools. Unfortunately, to many low vision users smart phones run into the same issues as screen readers and screen magnification tools [4,18,70], such as partial viewing causing a loss of context [32]. Many smart phones rely heavily on web-based content as well, where web-based content has been scrutinized for failing to meet accessibility requirements [32].…”

“…Unfortunately, to many low vision users smart phones run into the same issues as screen readers and screen magnification tools [4,18,70], such as partial viewing causing a loss of context [32]. Many smart phones rely heavily on web-based content as well, where web-based content has been scrutinized for failing to meet accessibility requirements [32]. In our studies with low vision participants, less than half used a smart phone, and only a third utilised accessibility features, with most commenting that they were either not aware of available features, were not interested, or did not think a smart phone was helpful to them.…”

We aim to help improve the quality of life of people with visual disabilities through the application of emerging technologies. Our current research investigates the viability of Virtual Reality (VR) as an aid for persons with visual disabilities. In this article, we explore the potential of VR assisted reading. We investigate the reading effects of VR equipment on persons with visual disabilities by utilising variations of standardised optometry-informed reading tests conducted across 24 participants. Test results uncovered that, when comparing a worn VR head-mounted display (HMD) to physical unaided tests, results within a HMD scaled better at closer distances while unaided tests scaled better with further distances. Using the findings collected and requirements elicited from participants, a prototype document reader was developed for reading text within a VR immersed 3D environment, allowing low vision users to customise and configure accessibility features for enhanced reading. This software was tested with 11 new participants alongside user evaluations, allowing us to discover how users perceived text best within our 3D virtual environments, and what features and techniques are required to evolve this accessibility tool further. The user test reported an overwhelmingly positive response to our tool as a feasible
