Overview
The Show Red Vignette action briefly shows a red pulsing overlay at the edges of the screen. This provides immediate visual feedback that the learner did something incorrect — tapped the wrong object, gave a wrong answer, or violated a constraint. The effect is automatic and brief, fading out on its own. No configuration is needed — simply use it to provide error feedback.When to Use
- Incorrect object interaction — Learner tapped or manipulated the wrong object
- Wrong answer selection — Learner chose an incorrect option in a multiple-choice question
- Safety violation — Speed threshold exceeded, unsafe interaction detected
- Boundary violation — Learner attempted to go to a restricted area
- Compliance failure — Learner skipped a required step or acknowledgment
- Constraint violation — Learner broke any rule or procedural requirement
Parameters
Example: Wrong Object Selection
Example: Speed Violation Feedback
Visual Effect Details
- Red overlay — A semi-transparent red tint covers the screen edges
- Pulsing — The overlay pulses briefly (typically 1-2 seconds)
- Automatic fade — The effect fades out automatically; no manual dismissal needed
- Non-intrusive — The 3D scene remains visible behind the overlay
Best Practices
1
Pair with feedback text
Combine the visual red vignette with Show Text explaining what went wrong.
2
Use for constraint violations
The vignette works best for safety rules, speed limits, and interaction errors.
3
Don't overuse
Reserve red vignettes for actual errors, not for normal feedback.
4
Return to the same state
After showing the vignette, usually transition back to the current state to let learners retry.
5
Test on different screens
Verify the vignette visibility on different screen sizes and brightness levels.
