“…Touch can also be used to substitute for vision even for charts. Refreshable Braille displays can be used in lieu of a text‐to‐speech screen reader for the machine‐readable portions of a chart [RSKS00], as well as more advanced method such as the Braille mouse [HHP11], which combines some features of a normal mouse with a Braille display, and embossed touch maps [dAVT05], which convey data in a 2D area using shape. Initial work [XIP*11] applies the TeslaTouch [BPIH10] electrovibration mechanism to allow for sensing 2D data using touch.…”

The majority of visualizations on the web are still stored as raster images, making them inaccessible to visually impaired users. We propose a deep‐neural‐network‐based approach that automatically recognizes key elements in a visualization, including a visualization type, graphical elements, labels, legends, and most importantly, the original data conveyed in the visualization. We leverage such extracted information to provide visually impaired people with the reading of the extracted information. Based on interviews with visually impaired users, we built a Google Chrome extension designed to work with screen reader software to automatically decode charts on a webpage using our pipeline. We compared the performance of the back‐end algorithm with existing methods and evaluated the utility using qualitative feedback from visually impaired users.
