ImageAssist: Tools for Enhancing Touchscreen-Based Image Exploration Systems for Blind and Low Vision Users

Abstract

Blind and low vision (BLV) users often rely on alt text to understand what a digital image is showing. However, recent research has investigated how touch-based image exploration on touchscreens can supplement alt text. Touchscreen-based image exploration systems allow BLV users to deeply understand images while granting a strong sense of agency. Yet, prior work has found that these systems require a lot of effort to use, and little work has been done to explore these systems’ bottlenecks on a deeper level and propose solutions to these issues. To address this, we present ImageAssist, a set of three tools that assist BLV users through the process of exploring images by touch — scaffolding the exploration process. We perform a series of studies with BLV users to design and evaluate ImageAssist, and our findings reveal several implications for image exploration tools for BLV users.

  • Prior research in 2-D image exploration, BLV video game, and AR accessibility found that structured, menu-based navigation was favored for ease of use and reliably accessing all objects, while free-form exploration provided greater autonomy and spatial awareness, but was more difficult to control.

    “This fi nding aligns with prior research in 2-D image exploration [57] and BLV video game [55] and AR [33] accessibility, which found that structured, menu-based navigation was favored for ease of use and reliably accessing all objects, while free-form exploration provided greater autonomy and spatial awareness, but was more difficult to control.”

    For the 2-D image-exploration portion attributed to this paper, the Introduction and Related Work describe touch exploration as offering autonomy and spatial understanding but requiring more effort and risking missed objects. User Study Findings §§6.1 and 6.4 report that the menu and beacon helped users find more areas and achieve more complete coverage. The paper does not establish that users favored menu-based navigation over free-form exploration: §6.1 says most chose touch as their primary method and used the menu as a supplement. The video-game and AR portions have separate citations and are not judged here. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
