ARGIRA v1.4.1: Visual and Touch-Target Accessibility Improvements to the Three-Layer Uncertainty Communication Prototype

ARGIRA v1.4.1 is a patch release of the ARGIRA prototype for automatic alt-text generation and three-layer uncertainty communication.

It is a new version of ARGIRA v1.4.0 (DOI: 10.5281/zenodo.21849334).

Visual and touch-target accessibility

This release improves the visual readability and touch usability of both prototype artifacts through a CSS-only accessibility refinement.

The changes include:

• Base interface text increased from 14px to 16px.
• Generated alt-text increased to approximately 16px.
• Primary controls increased to approximately 14px text.
• Secondary controls increased to approximately 13px text, with touch-target height increased from approximately 28px to 38px.
• Privacy and status text, and result metadata, increased to approximately 13px.
• The image-type badge retains its compact scale because it is a short status label rather than primary content.

The CSS modification was applied identically to the English and Spanish artifacts. The stylesheets remain byte-for-byte identical.

No changes were made to the HTML structure, element identifiers, JavaScript, classification logic, calibration logic, experimental-session mechanism (SESSION_ID, SESSION_CONDITION), thresholds, or data flow.

Accessibility verification carried forward from v1.4.0

Manual developer verification with Android TalkBack confirmed 8 of 9 checklist items for the forced experimental variants used in Phase 3C.

One interaction remains unresolved: the "More information" section should open through activation rather than merely receiving navigation focus.

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

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

Spanish localization carried forward from v1.4.0

The release retains two independently executable prototype artifacts:

• argira_demo_v2.html — English prototype.
• argira_demo_es.html — Spanish-localized variant.

The variants use separate HTML artifacts rather than an in-application language selector.

Both derive from the frozen v1.3.0-alpha prototype and preserve the same experimental session mechanism, identifiers, classification logic, calibration logic, thresholds, and data flow.

Structural parity between the two artifacts is preserved.

Continuity

ARGIRA v1.4.1 does not introduce a new image-classification algorithm, calibration model, or experimental condition.

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

This release is intended to support continued research, reproducibility, accessibility-oriented inspection, bilingual use through separate artifacts, and future evaluation with external users and additional assistive-technology environments.
