CARBON XIndependent public UI evaluation

Evidence edition / 23 October 2026 / en-US

Six perspectives, grounded in observations

AI-generated subjective evaluations grounded in the recorded journeys. These are not interviews, representative user research, satisfaction statistics, or disability simulation. Emotional scores: NOT MEASURED.

Beginner

Intent: Find a familiar game and understand access

Recorded actions: Home → search Fortnite → detail → read Sign in and comparison

Subjective interpretation: Discovery succeeded; primary action clearly requests sign-in. Purchase/inclusion language may leave access costs ambiguous.

Recommendation: Explain the distinction between game ownership and subscription access close to the action.

Joy / happiness / surprise: NOT MEASURED. No human participant.

Experienced player

Intent: Locate titles efficiently and retain context

Recorded actions: Search → detail → Back; inspect All games

Subjective interpretation: Query and results returned after Back. No filter/sort controls were observed in this gallery sample; search is the practical shortcut.

Recommendation: Evaluate filters only if product intent and catalog-scale tasks justify them; absence alone is not a bug.

Joy / happiness / surprise: NOT MEASURED. No human participant.

Keyboard-only

Intent: Navigate without pointer and recover from dialogs

Recorded actions: Enter activates comparison; Escape dismisses; Enter activates skip link

Subjective interpretation: Skip target received focus. Comparison focus returned to BODY in two trials. This was a sampled keyboard check, not a complete keyboard-only journey.

Recommendation: Restore opener focus; next perform a continuous Tab-only journey and verify modal focus containment.

Joy / happiness / surprise: NOT MEASURED. No human participant.

Low-vision/readability

Intent: Read access terms and use a narrow layout

Recorded actions: Review screenshots at desktop and 320px; inspect plan text

Subjective interpretation: Narrow layout wrapped and showed no document overflow. Some legal/renewal copy is visually small; contrast and zoom were not measured.

Recommendation: Measure text contrast and 200%/400% zoom before making accessibility claims.

Mobile browser

Intent: Browse a category and open a game at narrow width

Recorded actions: 390px Family Friendly → ASTRONEER → reload → home → comparison

Subjective interpretation: List and details adapted. Gallery recovered after reload. Comparison stacked; full scrolling and real touch not exercised.

Recommendation: Verify complete plan comparison, touch targets and virtual keyboard on a real mobile browser.

Joy / happiness / surprise: NOT MEASURED. No human participant.

Recovery and boundary

Intent: Recover from a dead end without committing to an account

Recorded actions: Unmatched query → clear; natural gallery error → reload; guide inspection

Subjective interpretation: Recovery affordances were useful. Sign-in and age boundaries were left intact.

Recommendation: Keep recovery copy actionable and differentiate loading from persistent failures.
