Abstract
Single Page Applications (SPAs) are characterised by changing a webpage's content without forcing a reload. While they increase the interactivity of web pages, they can also raise accessibility concerns, such as new content being displayed without screen reader users being aware. Another concern raised impacts the ability of current web accessibility evaluation tools to be able to assess SPAs. Current tools work by loading the DOM and assessing it. For SPAs, which change the DOM in response to user interaction, it is possible that evaluation tools do not have access to a significant part of a page's content. In this paper, we introduce QualState, a tool that can browse the different states of a SPA, and provide the DOM of the different states to QualWeb, an automated web accessibility evaluation tool, so their accessibility can be evaluated. We assessed QualState in a small set of SPAs and concluded that it increases the number of elements evaluated and improves QualWeb's ability to identify accessibility barriers.

Abstract
This article focuses on evaluating SONAAR (Social Networks Accessible Authoring), a tool that combines automation and end-user empowerment to enhance the accessibility of social media content. SONAAR aims to increase user engagement in creating accessible content and expanding the availability of accessible media online. Additionally, SONAAR provides supplementary information to support the authoring of accessible media content. To assess SONAAR's effectiveness, we conducted three distinct studies. First, we analyzed user patterns and behaviors through log analysis. Next, we evaluated the clarity, helpfulness, and efficiency of the additional documentation and its potential to improve engagement in accessible practices. Finally, we explored user perceptions and challenges when interacting with SONAAR. The obtained findings indicate positive user feedback and provide valuable insights for improvement. These results underscore the importance of raising awareness and offering support for accessible practices, as well as the necessity for enhanced platform backing. Our study contributes to advancing accessible content authoring, promoting inclusivity and accessibility in online social media. We suggest future research directions to facilitate broader adoption of accessible practices and address user engagement challenges, ultimately enhancing the accessibility of social media content.

Abstract
Many Virtual Reality (VR) locomotion techniques have been proposed, but those explored for and with blind people are often custom-made or require specialized equipment. Consequently, it is unclear how popular techniques can support blind people's VR locomotion, blocking access to most VR experiences. We implemented three popular techniques - Arm Swinging, Linear Movement (joystick-based steering), and Point & Teleport - with minor adaptations for accessibility. We conducted a study with 14 blind participants consisting of navigation tasks with these techniques and a semi-structured interview. We found no differences in overall performance (e.g., completion time), but contrasting preferences. Findings highlight the challenges and advantages of each technique and participants' strategies. We discuss, among others, how augmenting the techniques enabled blind people to navigate in VR, the greater control of movement of Arm Swinging, the simplicity and familiarity of Linear Movement, and the potential for efficiency and for scanning the environment of Point & Teleport.
