Feedback from Ron 08/24/11

• in general: Ron is very pleased with the top-level things

The Text Dilemma

• problem: annotations are obstructing the images: this should NOT be the case
  • fonts ugly
  • text gets in the way of things you want to see
• different direction needed: show information in left bottom corner
  • two kinds of information
    • software wants to show information (push)
    • user requests information (pull)
  • in viewers: minimal information
  • in bottom left corner of Slicer GUI: medium details
  • somewhere else (in the annotation module): full details
  • cdash example: way of not to do it -> important information is covered by annotations
  • ohloh example: good example -> first minimal, then under cursor more details when probing

Possible Solution

• assign names (F1,F2,F3 for Fiducials, M1,M2,M3 for measurements, R1,R2 for ROI... ) and descriptions
  • name appears in viewers
  • description in bottom lower left on roll-over in viewers
  • in annotation module: full details: Name, description, options

General Changes (Target for RSNA release)

• take everything out which does not work properly (except for critical functionality)

Targeting the Text Dilemma

• name+description in bottom lower left, in viewers only name
  • possible problem: mouse over event on vtk widgets might not be easily realizable. Plan C could be a query mechanism, where the user requests this information through a keystroke or such
  • one letter naming checked in to svn 17837.

Slim down the Annotation Module

• get rid of text annotation
• get rid of bidimensional annotation
• just three annotation types: fiducials, measurements (ruler), ROIs
  • done in svn 17835

vtkWidget Changes

• ruler: ticks only in 2D, every centimeter, can be turned off
• handles for all annotations zooming behavior: should be like Slicer3
• ROI needs a name in the future: requires infrastructure change (not for RSNA)

Qt GUI Changes

• sliders in fiducial properties jumps weird: should have dynamic range or 0..20 for the beginning
  • size presets: medium is actual size, small and large presets
• property linking between elements of widgets so that the user has to change colors at one location
• hotspot icons for ruler placement: new icons on wendy's todo list
• second eye should be removed in tree view
• remove Create Panel
  • replace by toolbar
  • view transform in the toolbar: should be cancel
    • add a key (maybe ctrl) to have it pause mode
• screenshots and sceneviews go into toolbar
• take out advanced panel (svn rev. 17835)

MRML Changes

• changes related to linking properties
• fiducial list, so that saving many fiducials do not creates so many files
