• Project to improve self-made electronic KJ method tool

    • Homemade electronic KJ method tool grouping] that I made about 5 years ago and neglected.
    • I thought it would be rather good assuming iPad Pro + Apple Pencil, so I restarted (2018-09-19)
    • Development code name Regroup
  • Development on iPad

  • I’ll use Pencil for editing.

  • Overlap order issues in SVG

  • Store data in Cloud Firestore



The React version does not cause the text to disappear on touch when displayed on the iPad, so it must be an issue with the older version of Raphael.



  • At the time it was created, the screen was too small to be practical.

  • I opened it on my iPad Pro and confirmed that it works.

    • Zooming out is not accepted immediately after opening (it transitions to tabbed view).
    • If it is zoomed in, it can be zoomed out.
    • Zoom in and parallel movement can be performed with the two-finger gesture.
      • →Can I zoom out to where I can see the entire sticky when I open it, and then zoom in and use it from there?
    • Stickies can be moved by finger or Pencil.
      • However, there is a mysterious phenomenon where the text disappears when the text portion is dragged.
    • By default, 100 cards are lined up tightly to fill the screen.
      • But even if you double the height and width, you can still read quite a few words.
      • If you can zoom in and out smoothly and intuitively, you can go far enough.
  • Extra features

    • The current version has Ability to write arrows etc. between boxes.
      • What is really needed in doing KJ method electronically is support for “group formation”.
      • Arrow additions, etc., should be done in the A-type diagramming process after grouping.
      • Arrow functionality is not necessary for the grouping phase, confusion caused by having many menus is detrimental
      • Debugging UI for developing on a PC is cluttering up the bottom.
        • When I open it on my iPad, I see it by default.
        • It would be better to hide this at first and have it appear when you press the development menu.
      • To illustrate, you can take a screenshot or export an image and use the iPad’s own functions to write on it.
        • Should there be PDF export?
  • Missing features

    • Make the image a sticky note
      • I think the approach of interpreting a sticky as an image if its content starts with http is fine.
    • grouping
      • You can use “Bundle mode start button→tap (toggle) the target sticky→done button/cancel button”.
      • I just created a lasso tool and it has the same number of moves as “lasso mode”, “selection”, and “grouping”.
      • procedure
        • Bundling mode starts
        • Tap the target sticky
        • Finish button
        • Select a nameplate or create a new one
