METHOD AND SYSTEM FOR ACCESSIBLE DATA VISUALIZATION ON A WEB PLATFORM

The present disclosure relates to a method and system for accessible data visualization on a web platform. At present keyboard limitations exist in a browser that do not permit full access to a data visualization. Therefore, in the present disclosure when the user is focusing a node, all of the previously mentioned interactivity rules apply to it, based on the kind of chart element it represents. When the user takes a keyboard action on that node, it is simulated as though that action took place in the chart space. So, the controller of the present disclosure renders what is necessary for focusing and the tabs needed at that moment for visualizing the data. The controller mirrors the interactivity of the chart displayed on the computer associated with the user. The controller facilitates the user to interact with the chart and enhances ease, efficiency and insights that are based on the information in the data visualizatio

Option-Driven Design: Context, Tradeoffs, and Considerations for Accessibility

In Option-Driven Design, users must interact with options and settings for systems to adapt to their needs. This approach places the burden on both the user and the system to make the interaction between user and system fit. The user must know and find which options they need and then adjust them. In addition, the system must be capable of robust change, similar to system change in ability-based design. In this micro-paper I outline the context for option-driven design, followed by several design negotiations, tradeoffs, and suggestions worth considering with this approach.Comment: 4 pages, 2 figures, 1 page of reference

The Micro-Paper: Towards cheaper, citable research ideas and conversations

Academic, peer-reviewed short papers are a common way to present a late-breaking work to the academic community that outlines preliminary findings, research ideas, and novel conversations. By comparison, blogging or writing posts on social media are an unstructured and open way to discuss ideas and start new conversations. Both have limitations in the proliferation of research ideas. The short paper format relies on the conference and journal submission process while blogging does not operate within a structured format or set of expectations at all. However, at times the demand exists for late-breaking ideas and conversations to arise in a raw form or with urgency but should still be archived and recorded in a way that promotes citational honesty and integrity. To address this, I present: The Micro-Paper, as a micro-paper itself. The Micro-Paper is a small, cheap, accessible, digital document that is self-published and archived, akin to a pre-print of a short paper. This meta micro-paper discusses the context, goals, and considerations of micro-paper authoring.Comment: 2 pages, 1 page of references, 1 figur

Data Navigator: An accessibility-centered data navigation toolkit

Making data visualizations accessible for people with disabilities remains a significant challenge in current practitioner efforts. Existing visualizations often lack an underlying navigable structure, fail to engage necessary input modalities, and rely heavily on visual-only rendering practices. These limitations exclude people with disabilities, especially users of assistive technologies. To address these challenges, we present Data Navigator: a system built on a dynamic graph structure, enabling developers to construct navigable lists, trees, graphs, and flows as well as spatial, diagrammatic, and geographic relations. Data Navigator supports a wide range of input modalities: screen reader, keyboard, speech, gesture detection, and even fabricated assistive devices. We present 3 case examples with Data Navigator, demonstrating we can provide accessible navigation structures on top of raster images, integrate with existing toolkits at scale, and rapidly develop novel prototypes. Data Navigator is a step towards making accessible data visualizations easier to design and implement.Comment: To appear at IEEE VIS 202
