The best news for my Vision Test Battery FrACT₁₀

  • Basic operation unchanged!

More good news – Important new features

  • PDF output is now possible. With operator intervention the results and the full testing history can be saved in a PDF file – this advances FrACT₁₀ towards 21 CRF Part 11 compliance
    • Find it at Settings>General>Export results to, set to Full history→PDF.
    • Works best with Chrome or Edge, there a file-save dialog will appear, allowing you to change the suggested filename and choose destination. FireFox and Safari have not (yet?) implemented the File System Access API (specifially, showSaveFilePicker), so there FrACT₁₀ falls back to normal download: PDF appears in the download folder and the filename is automatic (but sensible 😎).
    • Automatic filename is »FrACT_YEAR-MONTH-DAY_HOUR_MINUTE.pdf«. If interest is there, I could add the ID and/or eye (below) to this.
    • I gratefully acknowledge the nudge and insightful advice by Ursula Garczarek on 21 CRF Part 11 compliance.
  • A bug fix for incorrect reaction times (since mid-March, 1000ms too short {thus often negative} if you need to correct).
  • Optionally, an ID identifying the test situation, and eye tested can be entered beforehand. This is then saved along with the testing results for permanent storage.
    • Find it at Settings>Misc>ID / eye
  • The library “simplestatistics” I’m using for some data crunching had vanished at its old URL. Now I found it again and can give credit.
  • Alphabetically sorted Presets – They had grown “organically”, now better organised.
  • Improved tooltips, added where missing
  • Internal refactoring to simplify
  • Fixed bug: Reaction time included the ISI delay
  • Even more details in the commit history.

A change, possibly breaking

  • The format of the exported data record has changed to embody ID and eye condition. First time in 5 years! vsExportFormat is now at 6. Position of the decimal marker field unchanged, so parsers need not be adjusted for international number formats.
  • This reminds us: for ongoing studies, use a frozen version!
