Interface and accessibility
Research beta 0.3 / 2 November 2026
Implemented interaction design
- A home overview and full studio within one navigation shell. Returning to the overview keeps the mounted studio and its in-memory review; refreshing or leaving can lose that review.
- Home contains no 3D viewer and loads no renderer or model assets. Anatomical models, labeled layers and camera controls are available only after opening Studio.
- Semantic headings and navigation, skip link, native dialogs, responsive layouts, reduced-motion rules, and text labels accompanying status colors.
- Explicit loading, recovery and WebGL fallback states. Supported research files are still processed locally in the studio.
- The parent and embedded studio accept only same-origin messages from the expected window. UI messages contain case keys, loading/dirty state and frame height; scan voxels and review notes are not sent to the parent shell.
Demo entry points
Home offers a guided anatomy walkthrough, a second CT study, and a sample scan picker. The Studio toolbar keeps Guided anatomy demo, sample scans, Sources and Export review visible. Built-in DICOM, NIfTI and synthetic phantom samples run through the bounded local parser after release-hash verification. They require no personal files or own-data acknowledgement. Import controls and dialog dismissal remain available if a teaching study fails to load. For your own files, the acknowledgement is required and an inline hint explains the next step.
Keyboard use
Use Tab and Shift+Tab to move between controls. Enter activates links and buttons. Open Studio to use its labeled camera presets, layer controls and CT sliders. Escape closes the project dialog. Returning to Overview hides the studio while retaining its in-memory review.
Verification scope
The engineering record lists checks actually run, including automated accessibility scanning, navigation, responsive viewports and the retained review workflow. Automated checks do not replace assistive-technology testing, independent accessibility evaluation or representative physical-device coverage.
