ARGIRA v1.4.3: Three-Layer Uncertainty Communication Prototype for Automatic Alt-Text — Accessibility & Localization Release

ARGIRA v1.4.3 is a refinement release of the ARGIRA prototype for automatic alt-text generation and three-layer uncertainty communication, focused on accessibility, interface clarity, bilingual localization, and more precise communication of the prototype's scope and limitations.

It is a new version of ARGIRA v1.4.2 (DOI: 10.5281/zenodo.21852709).

Interface and content refinement

This release refines the introductory explanation of what the prototype does and, importantly, distinguishes the capabilities of this specific demonstration from the broader ARGIRA project.

The demonstration included in this release uses a statistical pixel-based heuristic and predefined templates. It does not incorporate a computer-vision model for semantic image recognition. It can estimate the likely type of an image and expose the statistical signals and uncertainty behind that estimate, but it does not identify objects, people, scenes, or other semantic content within the image.

The broader ARGIRA project includes other tools and experimental approaches that can work with image content. This distinction is now stated explicitly in the demonstration so that the limitation of this particular prototype is not incorrectly attributed to ARGIRA as a whole.

The interface description has also been refined to explain more clearly that the generated text is an automatically constructed type-level description rather than a semantic description of the image.

CORS warning and interaction refinement

The browser CORS limitation warning is now presented as a native expandable disclosure rather than as a permanently expanded block.

The warning remains available to users who need the information, while reducing visual and navigational noise when the application is first opened.

The disclosure uses the existing accessible details/summary interaction pattern and remains compatible with the accessibility-only mode. In accessibility-only mode, the warning remains excluded from the reduced navigation path.

Accessibility and localization

The release includes further accessibility-oriented content refinement and review of visible and accessible text in both language variants.

The English and Spanish prototypes were reviewed for consistency of interface text, accessible labels, dynamic messages, metadata panels, result information, and explanatory content.

The two artifacts remain independently executable HTML prototypes rather than using an in-application language selector.

The accessibility review also preserves the previously established accessibility-only navigation behavior and the essential result path: image type, confidence, generated alt-text, copy, and previous/next result navigation.

Accessibility verification scope

Manual developer verification with Android TalkBack carried forward from previous releases remains part of the accessibility evidence for the prototype.

Apple VoiceOver was not evaluated because an available Apple/VoiceOver testing environment was not available. This remains an untested scope, not a failed validation.

No external user study or participant evaluation was conducted for this release.

Experimental scope and continuity

ARGIRA v1.4.3 does not introduce a new image-classification algorithm, calibration model, or experimental condition.

The underlying heuristic classification, calibration logic, thresholds, embedded data, identifiers, and experimental session mechanism are preserved.

The release remains an experimental research artifact and is not presented as a finished product or as validated accessibility technology.

The purpose of this release is to support continued research, reproducibility, accessibility-oriented inspection, bilingual use, clearer communication of uncertainty and limitations, and future evaluation with additional assistive-technology environments and external users.
