FUSE 2D Player Accessibility Conformance Report
Section 508 Edition · based on VPAT® Version 2.5Rev
A newer edition of this report exists: the fourth edition, re-tested on the build of 30 October 2026, where the author's DEV button is no longer on a trainee's screen or in the Tab order. This third edition is kept as it was measured, on the build of 29 October 2026.
Name of Product/Version: FUSE 2D Player, the browser player for FUSE trainings, as served by the 17 hosted FUSE 2D trainings on 2026-10-29 (build of 29 October 2026: keyboard and screen-reader access, and a question is read out as its stem alone, its follow-up line only once it is answered). Each training's exact build is identified by the SHA-256 fingerprint on its test-evidence page.
Report Date: 2026-10-29 (third edition). It replaces the second edition of 22 September 2026, measured on that day's build; that edition, and the first, stay published as they were.
Product Description: A training player that runs in any modern browser on phones, tablets and computers. A trainee works through steps in 360° scenes, still pictures and video: reading cards, answering questions, making timed decisions, and finding, pressing or marking things in the scene.

Notes: This is a self-assessment by the vendor, on ITI's template, of the player a trainee uses. It does not cover the FUSE Builder web platform or the FUSE Studio authoring tool, which will get editions of their own, or the VR headset app. Every conformance level was set against a test run on the live builds on 2026-10-29, or against the player's source where a remark says so. It is a dated measurement: when a gap below is fixed, the criterion is re-tested and the report is reissued with a new date.
Evaluation Methods Used:
- Keyboard-only play-through of all 17 trainings, no mouse: Tab, Space, Enter and the arrow keys, with a step counted as keyboard-operable only if it was finished with keys alone from the moment it appeared (367 of 390 steps). Focus visibility was measured at every Tab stop by comparing the focused and blurred computed style.
- axe-core 4.10.3 (WCAG 2.0, 2.1 and 2.2 A and AA rules) in Chrome, on the first card, on the first step of every kind in each training, and on the finish screen.
- Narration against on-screen text for every spoken line (379 lines).
- Reflow at 320 CSS px, 200% zoom as a 683 x 384 viewport, and the WCAG text-spacing override.
- A full play-through on seven phone and tablet shapes, upright and sideways, plus a laptop (136 runs), with the layout measured before every screen.
- A live-site sweep confirming the bytes the public sites serve equal the files tested.
- Review of the player's source for criteria no run can see (sound control, motion sensors, hover content).
- Not performed: a full pass with a screen reader (NVDA, JAWS or VoiceOver) by a person; testing on physical phones (shapes were emulated in Chrome, and iPhone Safari as WebKit on Windows); Firefox; flash analysis of video content.
Summary
Of the 50 WCAG 2.1 Level A and AA criteria: 32 Supports, 12 Partially Supports, 2 Does Not Support, 4 Not Applicable.
Known gaps (Does Not Support)
- 2.5.1 Pointer Gestures (WCAG 2.1)
- 1.2.5 Audio Description (Prerecorded)
What is still open, and not part of this release: on a touch screen, looking around and drawing a box are drags with no single-tap alternative (2.5.1; a keyboard does both), and 360 video scenes have no audio description track (1.2.5). Each will be re-tested and this report reissued when it ships.

WCAG 2.x Report
Section 508 incorporates WCAG 2.0 A and AA by reference (E205.4, E207.2, 602.3). WCAG 2.1 criteria are marked.
| Criteria | Conformance Level | Remarks and Explanations |
|---|---|---|
| 1.1.1 Non-text Content | Partially Supports | Controls, and the markers a trainee presses in the scene, carry an accessible name (a marker is named by its number and label, see 4.1.2). The 360 scene itself has no text alternative beyond the narration and card text that describe it. |
| 1.2.1 Audio-only and Video-only (Prerecorded) | Partially Supports | Narration: 368 of 379 spoken lines across the fleet were on screen as text while they played (measured). Audio-clip steps show their transcript. 360 video scenes have no separate text or audio description of what the video shows beyond the card narration. |
| 1.2.2 Captions (Prerecorded) | Partially Supports | The player's narration is the on-screen card text read aloud, so the text is always present. Video scenes that carry their own soundtrack (the Metro Box technician videos) are not captioned; the player has no caption track support. |
| 1.2.3 Audio Description or Media Alternative (Prerecorded) | Partially Supports | Card narration describes what each step is about, but 360 video scenes have no audio description or full text alternative of the video content. |
| 1.3.1 Info and Relationships | Supports | Answer choices are real radio buttons and checkboxes inside their labels; the control bar is a labelled toolbar, the scene map is a labelled dialog, each card's title is a heading, and markers in the scene are buttons. |
| 1.3.2 Meaningful Sequence | Supports | Card content reads in the order it is shown; one card is in front of the trainee at a time. |
| 1.3.3 Sensory Characteristics | Partially Supports | Some instructions are spatial by nature ("turn to the unit on your left", "find every one in the room"). The card text names the object as well, but the task itself is visual. |
| 1.4.1 Use of Color | Supports | Right and wrong answers are stated in words on the verdict card, not by colour alone. |
| 1.4.2 Audio Control | Supports | Narration starts only after the trainee presses to start it. Mute (on screen and the M key) and Pause stop all sound: narration, video soundtrack and clips (source review). |
| 2.1.1 Keyboard | Partially Supports | Measured by playing every training with the keyboard only: 367 of 390 steps were finished with keys alone, and 7 of 17 trainings could be finished end to end without a pointer. Markers are buttons reached with Tab; the scene itself is one control where the arrow keys turn the room (or move a pointer on a flat picture) and Enter presses at the centre, which is how a trainee finds things and draws a box (two corners) from the keyboard. Steps that still needed a pointer in the run: find every one in the scene, open numbered badges, press a marked point. |
| 2.1.2 No Keyboard Trap | Supports | Tab moved through every card and control and out again on all 17 trainings; focus was never held. |
| 2.1.4 Character Key Shortcuts | Supports | The single-letter shortcuts (M mute, P pause, R replay, L look around, B back) act only while focus is on the scene, the control bar, the mute button or a marker, which the criterion allows; with focus anywhere else, or with Ctrl, Alt or Cmd held, a letter does nothing (measured on every training: M with nothing focused did not mute; the modifier case is tested by the player's own keyboard suite). |
| 2.2.1 Timing Adjustable | Partially Supports | 1 of 17 trainings contain timed decision steps. Pause holds the clock for as long as the trainee wants, and Back re-runs the step on a fresh clock, but there is no setting to extend or turn off the time limit. Reading and review timers only delay the Continue button. |
| 2.2.2 Pause, Stop, Hide | Supports | The Pause control (and P) stops narration, video and every clock in the player. The one repeating animation (the "More below" nudge) runs only when the user has not asked for reduced motion. |
| 2.3.1 Three Flashes or Below Threshold | Supports | The player produces no flashing content. The video scenes in the fleet were not analysed with a flash-measurement tool. |
| 2.4.1 Bypass Blocks | Supports | Each training is a single screen with no repeated navigation blocks to bypass; the card is the main content. |
| 2.4.2 Page Titled | Supports | Every training's page title is the training's name (measured on all 17). |
| 2.4.3 Focus Order | Partially Supports | Tab order follows the screen. A new card puts focus on its first control, and when a card is redrawn focus returns to the same control: focus fell back to the top of the page after 423 of 1567 key presses during the keyboard play-through, and up to 1 Tab stops could not be seen. |
| 2.4.4 Link Purpose (In Context) | Supports | The few links in the player say where they go. |
| 2.5.1 Pointer Gestures (WCAG 2.1) | Does Not Support | Looking around a 360 scene is a drag, and a draw-a-box step is a drag; on a touch screen neither has a single-tap alternative. A keyboard can do both (see 2.1.1), but this criterion asks for a single-pointer alternative, which is not built yet. |
| 2.5.2 Pointer Cancellation (WCAG 2.1) | Supports | Markers and buttons act on release (the click event), not on press. |
| 2.5.3 Label in Name (WCAG 2.1) | Supports | Visible button text is the start of each accessible name. |
| 2.5.4 Motion Actuation (WCAG 2.1) | Supports | Nothing is operated by tilting or shaking the device (source review: the player reads no device-motion sensors). |
| 3.1.1 Language of Page | Supports | The page language is declared (lang="en" on 17 of 17, measured). |
| 3.2.1 On Focus | Supports | Moving focus never changes the step, the scene or the card. |
| 3.2.2 On Input | Supports | Ticking an answer does not submit it; the trainee presses Check or Continue. |
| 3.3.1 Error Identification | Supports | A wrong answer is identified in text on the verdict card, with the reason. |
| 3.3.2 Labels or Instructions | Supports | Every question and task states what to do on its card. |
| 4.1.1 Parsing | Supports | Obsolete in WCAG 2.1 per the W3C's 2023 errata; recorded as Supports as that errata directs. |
| 4.1.2 Name, Role, Value | Supports | The markers a trainee presses in the scene are buttons with a name ("Marker 3: the valve"): 138 of 138 markers met in the keyboard play-through were focusable, named buttons (measured); the scene is a named application region; the start-narration prompt and the card text, when it scrolls, are named and reachable. |
| Criteria | Conformance Level | Remarks and Explanations |
|---|---|---|
| 1.2.4 Captions (Live) | Not Applicable | The player has no live audio. |
| 1.2.5 Audio Description (Prerecorded) | Does Not Support | 360 video scenes have no audio description track. |
| 1.3.4 Orientation (WCAG 2.1) | Supports | Works upright and sideways: the play-through reached the end on phones and tablets held both ways (132 of 136 device runs clean). |
| 1.3.5 Identify Input Purpose (WCAG 2.1) | Not Applicable | The player asks for no personal information. |
| 1.4.3 Contrast (Minimum) | Supports | No text on the cards, buttons or finish screen failed the contrast rule on any of the 17 trainings. Text over a live 360 scene (a marker's name on hover) cannot be measured by the rule engine and was not measured by other means. |
| 1.4.4 Resize Text | Supports | At 200% zoom (measured as a 683 x 384 CSS viewport) 17 of 17 trainings had no sideways scrolling and 17 kept the main button on screen. Pinch-zoom works on phones and tablets over the cards and controls; over the 360 scene a pinch zooms the scene's own view instead. |
| 1.4.5 Images of Text | Supports | The player puts no text in images; text that appears inside a photographed or generated scene is part of the scene. |
| 1.4.10 Reflow (WCAG 2.1) | Supports | At 320 CSS pixels wide, 17 of 17 trainings had no sideways page scroll and 17 kept the main button on screen. The 360 scene is two-dimensional content, exempt as such. |
| 1.4.11 Non-text Contrast (WCAG 2.1) | Partially Supports | Buttons and their focus rings were designed against the player's own card colours. Markers sit over photographs and generated scenes, where contrast varies with the picture and was not measured. |
| 1.4.12 Text Spacing (WCAG 2.1) | Partially Supports | With the WCAG text-spacing override applied to the first cards, 16 of 17 trainings clipped no text. |
| 1.4.13 Content on Hover or Focus (WCAG 2.1) | Partially Supports | A marker's name appears as a tooltip on mouse hover; it stays while hovered, but it cannot be dismissed with Escape (source review). |
| 2.4.5 Multiple Ways | Not Applicable | A training is a single page and a step in a process, which the criterion exempts. |
| 2.4.6 Headings and Labels | Supports | Each card carries its kind and title, and every button says what it does. |
| 2.4.7 Focus Visible | Supports | 541 of 541 visible Tab stops visited during the keyboard play-through changed appearance when focused (measured: focused versus blurred computed style). |
| 3.1.2 Language of Parts | Supports | Content is in one language per copy. |
| 3.2.3 Consistent Navigation | Supports | The control bar is the same on every step of every training. |
| 3.2.4 Consistent Identification | Supports | Controls with the same function carry the same name throughout. |
| 3.3.3 Error Suggestion | Supports | The verdict card explains the right answer and why. |
| 3.3.4 Error Prevention (Legal, Financial, Data) | Not Applicable | The player makes no legal or financial commitment and changes no user data. |
| 4.1.3 Status Messages (WCAG 2.1) | Partially Supports | The player has a polite live region that announces each new card, verdicts, finds ("Found 2 of 5") and hints without moving focus. Measured in the keyboard play-through: 371 of 390 steps were announced while they were on screen (not announced: guide: Four crews, one floor; guide: Four seats, four sets of belts; guide: The way out, and the way it stays shut; guide: Three faces you can trust anywhere; …). |
Revised Section 508 Report
| Criteria | Conformance Level | Remarks and Explanations |
|---|---|---|
| 302.1 Without Vision | Partially Supports | Cards, questions, decisions and verdicts are text a screen reader reads, new cards and verdicts are announced (see 4.1.3), and the markers in a scene are named buttons (see 4.1.2). Finding things in a 360 scene or drawing a box around one is still a visual task: a trainee who cannot see the scene can reach the named markers but not a search target, which is unnamed by design. A full screen-reader pass by a person was not run. |
| 302.2 With Limited Vision | Partially Supports | Browser zoom and pinch-zoom work (see 1.4.4 and 1.4.10) and card text meets minimum contrast (see 1.4.3). Text over a live scene was not measured. |
| 302.3 Without Perception of Color | Supports | No information is carried by colour alone (see 1.4.1). |
| 302.4 Without Hearing | Partially Supports | Everything narrated is on screen as text; video soundtracks are not captioned (see 1.2.2). |
| 302.5 With Limited Hearing | Partially Supports | As 302.4; narration can be replayed at any time. |
| 302.6 Without Speech | Supports | No step requires speech. |
| 302.7 With Limited Manipulation | Partially Supports | Most steps can be done from a keyboard or a switch that sends keys (367 of 390 measured, see 2.1.1); on a touch screen, looking around and drawing a box are still drags (see 2.5.1). |
| 302.8 With Limited Reach and Strength | Partially Supports | No step needs force or reach beyond the device's own screen or keyboard; the touch-screen drags in 2.5.1 still apply. |
| 302.9 With Limited Language, Cognitive, and Learning Abilities | Partially Supports | Plain-language cards, Replay, Pause and Back are always available; timed decision steps add time pressure by design (see 2.2.1). |
| Criteria | Conformance Level | Remarks and Explanations |
|---|---|---|
| All of Chapter 4 | Not Applicable | The player is software; it includes no hardware. |
| Criteria | Conformance Level | Remarks and Explanations |
|---|---|---|
| 501.1 Scope – Incorporation of WCAG 2.0 AA | See WCAG 2.x section | The player is web content; see the WCAG tables above. |
