The 20 questions

  1. Why must an AR trigger image be unique?

    • To reduce file size
    • To increase brightness
    • To speed up animation
    • To prevent confusion

  2. Why should an AR trigger image avoid blur?

    • Increasing file size
    • Reducing colour depth
    • Lowering contrast levels
    • Ensuring reliable recognition

  3. Why should an AR trigger contain minimal text?

    • Text reduces distinctiveness
    • Text increases file size
    • Text causes crashes
    • Text stops rendering

  4. What problem does excessive blank space cause in an AR trigger image?

    • Inverts colours
    • Provides few features
    • Doubles processing time
    • Corrupts the file

  5. Which design approach helps AR triggers stand apart from each other?

    • Solid blank areas
    • Repeated patterns
    • Monochrome gradients
    • Varied graphic detail

  6. Why should a designer avoid repeated graphic elements across different AR triggers?

    • Reduces development time
    • Causes user confusion
    • Improves recognition speed
    • Increases file size

  7. A product's trigger must work where no printed card is allowed. Which type fits?

    • Marker-based
    • Markerless
    • QR code tag
    • Static card

  8. What primary factor determines the choice of an AR trigger type?

    • Environment and context
    • Audio volume
    • File extension
    • Screen resolution

  9. Which trigger type involves replacing an object's view with augmented content?

    • Marker-based image
    • Static display
    • Superimposition
    • Markerless scanning

  10. Which feature is essential for a good AR trigger image?

    • Being animated
    • Being unique
    • Being text-heavy
    • Being monochromatic

  11. A museum uses a unique poster image to show exhibit information. What trigger type is this?

    • Markerless
    • Superimposition
    • Location based

  12. What is the main risk of using a blurred AR trigger photo?

    • Audio distortion
    • Recognition failure
    • File corruption
    • Colour inversion

  13. How should a poster trigger with too much text be improved?

    • Add more paragraphs
    • Simplify the text
    • Remove all graphics
    • Increase font size

  14. Why must an AR trigger be tested thoroughly before release?

    • Measure download speed
    • Verify audio bitrate
    • Check battery drain
    • Confirm reliable recognition

  15. What problem occurs if multiple AR triggers look too similar?

    • Wrong content shown
    • Screen brightness drops
    • App crashes instantly
    • Files delete themselves

  16. Which trigger quality helps reduce misrecognition in poor lighting?

    • Low resolution
    • Pastel shades
    • High-contrast graphics
    • Monochrome blending

  17. What is the primary function of an AR trigger?

    • Activates digital content
    • Stores user data
    • Renders 3D models
    • Controls audio volume

  18. Which factor should decide the trigger type for a museum exhibit?

    • Ticket price
    • Exhibit location
    • Visitor age
    • Gift shop stock
