Viewing compared Braille regions

To view the inspected image or file, use the track wheel to zoom in or out of the inspection view panels.
Use the mouse and move it around to pan the image. 

To review multiple pages, navigate through them using the Page Navigation (3) drop-down menu at the bottom left of either panel.

To move to a different Braille region, click it in the Braille Regions found panel (4) in your layout. It displays in the Inspection View Sample panel, outlined in red in both it and the Overview panel (6). The corresponding Braille details/ parameters are updated in the Braille Details panel (5).

The Braille Details panel

The Braille Details panel (displayed above) features a wide variety of parameters. When one is highlighted in red, it has failed the ISO Standard 17351:2013 for dot diameter and spacing:

  • Braille Region: Region detected (and outlined in red in the Inspection View).
  • Language: Language of translation.
  • Translation: Translation of Braille in the selected language; When the Master and Sample files are being compared, separate Master/Sample Translation fields display.
    NOTE: Unrecognized Braille characters are represented by an underscore. 

Basic Information

  • Dots: Number of dots.
  • Characters: Number of letters.
  • Lines: Number of lines detected.

Braille parameters

  • Dot H Spacing: Average horizontal spacing between dots.
  • Dot V Spacing: Average vertical spacing between dots.
  • Character Spacing: Average spacing between characters.
  • Word Spacing: Average spacing between words.
  • Line Spacing: Average spacing between lines

Height Information (Inspection with frontside scans only) 

  • Dot Type: Type of dots detected (dome, bell, plateau) 
  • Above Threshold: Percentage of detected dots above the set threshold (%) 
  • Mean Height: Average height of detected dots (mm) 
  • Min/Max Height: Minimum and maximum height of detected dots (mm) 
  • Standard Deviation: Standard deviation in height of detected dots (mm) 


Review the Differences 

  • Click on the Braille region to be inspected in the Braille Regions found panel.
    It gets highlighted and displayed in the Inspection View.
  • When running Braille comparison, missing (highlighted with a “minus” sign”) and extra dots (highlighted with a “plus” sign) get identified accordingly. 
  • Dots follow the below legend:

Modifying Dots

To add a Braille dot in the selected region in the Inspection View Sample panel,
