−
== Current status and TO-DO ==
+
Since a left-mouse-button click in Slicer's 3D or Slice Viewers can mean different things at different times; this can be confusing to users, and can lead to mistakes. We are currently deciding a good paradigm for defining and controlling mouse modes in Slicer's 3D viewer and 2D slice windows. We rely on mouse interaction to transform the view, and to perform explicit actions like placing a fiducial, selecting and moving a fiducial, collecting voxel-value samples, and so on. The challenge is to make all actions possible with just the left mouse button (some mice have only one button), and to disambiguate what a left-mouse-button click in the 3D and Slice viewers means.
  
−
The existing base classes form a basic framework for the UI. For the Alpha/Beta releases, we provided a main application window with the general layout described in our current design. For the Release deadline, we plan to complete the overall application GUI. Things we are focusing on:
+
'''Goals:''' We'd like the interaction paradigm to have the following features:
  
−
* choose radiobutton/checkbutton with/without icon convention
+
* Consistent in all slice windows and 3D viewer
−
* finish content for slicer human interface and style guidelines
+
* Reflect common software conventions
−
* theme font, match to screen resolution, set in application settings
+
* Intuitive and easy for beginners
−
* finish slicer mouse modes
+
* Fast for intermediate and expert users
−
* think through color palette to support semantic applications
+
* Rely on only one mouse button (but accommodate multiple mouse buttons)
−
* update module GUI how-to
+
* Support direct manipulation as much as possible
−
* refine ROI toolbox design, work with developer to implement
+
* Provide clear visual feedback about current mouse mode
−
* refine lightbox viewer
+
* Support both '''view transformation''' (rotate, pan, zoom) as the primary mode, and a set of '''mouse actions''' (pick, manipulate, place, etc..., and '''window/level adjustments''' according to convention in medical imaging software packages.
−
* implement mechanism to specify oblique view
+
* Consistent classification of all direct-manipulable entities in slicer into a set of groups, and have consistent behavior for 'selecting' all entities within each group.
−
* build classes for pop-up information (help and context info)
 
−
* copyrights

== Scene snapshot panel ==
 
−
This GUI panel allows the scene to be recorded at any point and restored later; it's particularly useful for sharing relevant views of a scene with collaborators or for instruction. The layout can be made more compact and improved in general. Also, colors on the 'restore' button are overly bold, and the red/green imply more than they intend.

 +
* Would like to free up right mouse button to invoke the display of a 'context menu', but well-established convention uses right mouse button for zooming in all viewers.

Instead of a finite set of layout options, we would like to provide users the ability to select among a richer set of layouts, some created to be appropriate for analyzing certain kinds of studies, and the ability to customize their application layout as well. We have begun working on ideas at the NA-MIC January 2009 AHM.

Currently, radiobutton and checkbutton indicators display their state differently on different platforms Slicer supports. For instance, visually similar indicators on linux and windows actually represent different states. This can be confusing for people who work on both platforms. So instead of using the default Tk bitmaps for the indicators, we are proposing to use our own image data which will display the same on all platforms.

−
* use methods SetImageToIcon and SetSelectImageToIcon to display selected/deselected icons, selected/deselected icons+indicators

* provide blank icons with and without indicators for people to download.
 
  
−
Various experiments below for quickly readable icon state: either "selected" "deselected" or "disabled". Varying color, contrast, texture, etc. to find a design solution that reads out state quickly, at a glance. Drop shadow makes icons pop, but requires more pixels in each icon and we might have to re-do all existing icons to ensure good packing behavior. Also, we might get tired of this effect. Contrast differences add more visual "pop" than color differences. The greyed out dotted lines  provide a good solution for "deselected" state, with good visual contrast to the black outlined "selected" state. Both are clearly distinguished from the "disabled" state. Options P&Q are preferred below.

How do various icon configurations appear with and without icons, text, and indicators? The preferred convention would be to use either '''indicators + text or icons alone''' -- rather than indicators + icons together, or indicators, icons + text together. Sometimes this extra information may be necessary, so the last two embodiments are not ruled out.
+
Working with Dr. Jean-Jacques Lemaire, we are understanding the use of Slicer in a complicated tractography analysis, within the context of a particular workflow. This work is identifying usability issues, software bugs, and ideas for improvement. These pages are a touchstone for the project.

= Working problem: Navigating with fiducials (Issue resolved: implemented in Editor module and Edit Box)=
+
Below is a rough outline of the tractography analysis workflow currently in use (pending a proofreading check by J-J). The workflow can be broken down into general stages:
  
−
==GOALS:==
+
* setting up: including loading and saving and adjusting data display properties
−
* use fiducials as markers for features of interest
 
−
* allow navigation to fiducial points within a slice window and
 
−
* allow navigation to same fiducial point in all slice windows (a feature we're calling 'jumpslice').
 
−
* want to read-out which fiducial is currently being viewed while navigating
 
−
* want to expose these features in top level in each slice controller widget
 
−
* want also to keep the slice scrollbar from getting too small to use.
 
−
* want to indicate which slice scrollbar direction is R,L, S,I, A,P, depending on orientation
 
  
 +
* registration of target dataset to a reference dataset
  
−
==Proposed modification of vtkSliceControllerWidget:==
+
* exploratory and analytic tractography
  
−
The widget below shows a read-out/entry for current fiducial; buttons for navigate-to-next-fiducial and navigate-to-previous-fiducial. Slice scrollbar is longer, and contains labels at each endpoint.
+
[[Image:DTIworkflowOverview.png]]
−
 
−
[[image:FiducialNavigationSliceWindow.png | icons ]]
 
  
−
* user can navigate forward, backward using fiducial jump buttons
+
(if the figure should be corrected, please let me know how to fix -- maybe deformation should be part of the registration step).Data loading happens up front, but data and the scene may be saved frequently throught the workflow. Highlighted are some areas where serious usability issues have been flagged.
−
* user can enter an ordinal number (or name?) to jump to a fiducial (above, third fiducial of 12 total in the list)
 
−
* if viewers are unlinked, only the active slice viewer is updated
 
−
* if viewers are linked, all viewers are updated to show the slice containing the same fiducial.
 
−
* if a viewer's slice scrollbar is adjusted, its fiducial read-out is reset to ""
 
−
* any time a new fiducial is placed in a viewer, the fiducial read-out is updated to that (current) fiducial.
 
  
−
==Questions about placing and moving new fiducials:==
+
A plan to address these issues will be discussed on Dec 29/30 2008 at the next Slicer Developers meeting. Notes from that meeting and a proposed development plan will be posted here.
−
* should placing a new fiducial in the viewer cause a jumpslice event if all viewers are linked?
 
−
Seems we may not always want to trigger this by default. A reasonable solution for this is to unlink viewers when placing fiducials if you don't want the jumpslice behavior...
 
  
−
* should moving a newly placed fiducial in the viewer cause a jumpslice event if all viewers are linked? Again, seems we may not want this default behavior. And again, it seems easy enough to unlink viewers if you don't want the jumpslice behavior.
+
The sections below contain collected comments and suggestions for all workflow stages: '''Setting up''', '''Registration''', and '''Tractography'''. Markers on the figures indicate places where problems are reported.
  
−
* can we undo the creation and placement of a fiducal easily, so that while exploring the data, user can click, look, delete, and click again -- as an alternative to grabbing and moving an existing fiducial?
 
  
−
==Questions about navigation:==
+
[[Image:DTIworkflowSetup.png]]
−
* first time navigating, we start on fiducial#1. maybe we go forward to
 
−
fiducial 10 of 20. Next time navigating, do we continue on to 11, or restart at 1?
 
−
* Will there ever be too many fiducials to navigate?
 
−
* should the fiducial navigation entry (read-out) also take a fiducial NAME instead of number?
 
−
* Do we want to include other navigation options?
 
−
* With numerous fiducials, it may be hard to tell which fiducial is the corresponding one, when navigating them. Can we color the jump-fiducial temporarily to help integrate all displays?

At the June 2007 project week at MIT, we determined that we'll need to be able to pick several distinct things in Slicer, and the single "pick" mouse mode currently available was not going to provide the unambiguous picking functionality we need. Please add your picking needs to the list developing below. Thanks!

−
** entire models (to pick a bundle)
 
−
** ideally, a model group (to pick an entire structure like the corpus callosum that includes several bundles)
 
−
* It would also be very cool to have a plane widget for 3D intersection tract selection.
 
−
* for tractography and other things with an intermediate processing step before visualization (generation of glyphs or whatever)
 
−
** it may be useful for picking to indicate what was picked, if several models are displayed per node
 
−
** like: model #2 was picked, then my code can know that is a glyph model, rather than a line model, if that is ever needed.
 
−
** this depends on the final implementation of Alex's new cool display API, whether there is ever >1 model allowed

===Selection behavior===
+
= Working problem: Scene Snapshot Interface =
−
Once the concepts of 'active' and 'selected' are folded together, then all transformable data types will be either selected or unselected. When selected they should display a consistent visual treatment that makes this state clear.
 
  
−
'''Challenge:''' currently, 'active' models and volumes etc. are persistent, but since their 'active' state isn't visually indicated in the scene, this state remains kind of hidden -- and is only revealed in the vtkSlicerNodeSelectorWidgets in the GUI panel. But once 'active' and 'selected' represent the same concept and the visual presentation of any/all selected datatypes is displayed in Slicer viewers, this change of interactive behavior will be very noticeable to users.
+
== [[Image:Sketch.png]] [[Slicer3:UIDesign:WorkingProblems:SceneSnapshots | Link to Scene Snapshot UI Design]]==
  
−
Once the scene display becomes affected by any object's selected state, users are likely going to want an option to '''deselect all''' after they perform some processing on a selected dataset. Maybe the pick menu should have a "deselect all" option.

−
Currently, Slicer uses the concept of '''active''' datasets (the active volume, an active model, and active fiducial list, etc.) Application-wide, only a single datatype can be active at one time. This set of active datatypes is represented in the vtkMRMLSelectionNode.  
+
== [[Image:Sketch.png]] [[Slicer3:UIDesign:WorkingProblems:EditorToolbox | Link to Draft ROI design]] ==
  
−
The fiducials module also uses the concept of '''selected''' fiducials within any fiducial list. Many command line modules use only selected fiducials in their processing.

−
* defining '''Selected=0 or 1''' on a vtkMRMLTransformableNode.

−
* modifying the vtkMRMLSelectionNode to include multiple selected objects within any datatype
 
−
* extending the vtkSlicerNodeSelectorWidget to include checkbuttons rather than radiobuttons for nodes that can have multiple selections
 
−
* Changing '''active''' to '''selected''' in the codebase, (Fiducials module, ROI module, SlicesControl, ViewControl, ApplicationLogic and MRML XML parsing). MRML XML parsing should continue to support the "active" tag to remain backward compatible.
 
−
* Building the selection logic that appropriately marks objects as selected or deselected.
 
−
* Enforce the habit of setting and using the '''Pick''' mode for selection in addition to just overloading the '''Transform View''' mode with hot-keys.

===How Actions and View Transformations are done in Maya===
+
== GOALS ==
 +
Currently, radiobutton and checkbutton indicators display their state differently on different platforms Slicer supports. For instance, visually similar indicators on linux and windows actually represent different states. This can be confusing for people who work on both platforms. So instead of using the default Tk bitmaps for the indicators, we are proposing to use our own image data which will display the same on all platforms.
  
−
Maya is a very heavily used professional 3D animation package. Basic mouse bindings are:
+
* develop a custom slicer widget as an extension of vtkKWCheckButton
 +
* disambiguate current "deslected" radiobutton icon state -- it can be read as "disabled"
 +
* override method for turning the old indicator visible/invisible (always keep it off)
 +
* develop visually parseable convention for icons to represent:
 +
** selected
 +
** deselected
 +
** disabled
 +
* use methods SetImageToIcon and SetSelectImageToIcon to display selected/deselected icons, selected/deselected icons+indicators
 +
* provide blank icons with and without indicators for people to download.

−
* Zoom: alt-right or alt-right-and-middle mouse button
 
−
* Actions: always left mouse button, specific action depends on current mode
 
−
* Context menu: space bar
 
  
−
The advantage of this approach is that the left mouse button is freed up for many possible tasks such as selection, grabbing widget handles, etc.  Disadvantage is that it requires two hands to operate.  (A free copy of an almost-fully functional version of Maya is [http://www.autodesk.com/maya-trial available] for testing ).

Working problem: Mouse Modes in Slicer3

Since a left-mouse-button click in Slicer's 3D or Slice Viewers can mean different things at different times; this can be confusing to users, and can lead to mistakes. We are currently deciding a good paradigm for defining and controlling mouse modes in Slicer's 3D viewer and 2D slice windows. We rely on mouse interaction to transform the view, and to perform explicit actions like placing a fiducial, selecting and moving a fiducial, collecting voxel-value samples, and so on. The challenge is to make all actions possible with just the left mouse button (some mice have only one button), and to disambiguate what a left-mouse-button click in the 3D and Slice viewers means.

Goals: We'd like the interaction paradigm to have the following features:

  • Consistent in all slice windows and 3D viewer
  • Reflect common software conventions
  • Intuitive and easy for beginners
  • Fast for intermediate and expert users
  • Rely on only one mouse button (but accommodate multiple mouse buttons)
  • Support direct manipulation as much as possible
  • Provide clear visual feedback about current mouse mode
  • Support both view transformation (rotate, pan, zoom) as the primary mode, and a set of mouse actions (pick, manipulate, place, etc..., and window/level adjustments according to convention in medical imaging software packages.
  • Consistent classification of all direct-manipulable entities in slicer into a set of groups, and have consistent behavior for 'selecting' all entities within each group.


Current issues we want to address in existing Slicer3 implementation:

  • Mouse motion should default to "transform view" mode
  • Interaction relies on three mouse buttons (for rotate, pan, zoom, etc.) which aren't always present on all computers
  • It's currently easy to forget about persisting non-transform mouse modes (like pick or place) and assume that the view can be transformed -- leading to annoying errors. We want to avoid these errors
  • Would like to free up right mouse button to invoke the display of a 'context menu', but well-established convention uses right mouse button for zooming in all viewers.
  • Would like BOTH intuitive one-handed mouse-only interaction to be possible AND hot-key assisted shortcuts to be available.
  • We need to combine the concepts of active (volume or model, etc.), selected (volume or model...) and picked (volume or model...)
  • We need to design presentation treatments for all groups of selectable entities within Slicer, and a consistent presentation treatment for all selected entities within each group.

Working problem: Customizable layouts for Slicer3

Instead of a finite set of layout options, we would like to provide users the ability to select among a richer set of layouts, some created to be appropriate for analyzing certain kinds of studies, and the ability to customize their application layout as well. We have begun working on ideas at the NA-MIC January 2009 AHM.

Sketch.png Link to Naming conventions

Workflow overview and details on sub-steps

Below is a rough outline of the tractography analysis workflow currently in use (pending a proofreading check by J-J). The workflow can be broken down into general stages:

  • setting up: including loading and saving and adjusting data display properties
  • registration of target dataset to a reference dataset
  • exploratory and analytic tractography

DTIworkflowOverview.png

(if the figure should be corrected, please let me know how to fix -- maybe deformation should be part of the registration step).Data loading happens up front, but data and the scene may be saved frequently throught the workflow. Highlighted are some areas where serious usability issues have been flagged.

A plan to address these issues will be discussed on Dec 29/30 2008 at the next Slicer Developers meeting. Notes from that meeting and a proposed development plan will be posted here.

The sections below contain collected comments and suggestions for all workflow stages: Setting up, Registration, and Tractography. Markers on the figures indicate places where problems are reported.

So instead of using the default Tk bitmaps for the indicators, we are proposing to use our own image data which will display the same on all platforms.

  • develop visually parseable convention for icons to represent:
    • selected
    • deselected
    • disabled
  • use methods SetImageToIcon and SetSelectImageToIcon to display selected/deselected icons, selected/deselected icons+indicators
  • provide blank icons with and without indicators for people to download.

Working problem: Navigating with fiducials (Issue resolved: implemented in Editor module and Edit Box)

GOALS:

  • use fiducials as markers for features of interest
  • allow navigation to fiducial points within a slice window and
  • allow navigation to same fiducial point in all slice windows (a feature we're calling 'jumpslice').
  • want to read-out which fiducial is currently being viewed while navigating
  • want to expose these features in top level in each slice controller widget
  • want also to keep the slice scrollbar from getting too small to use.
  • want to indicate which slice scrollbar direction is R,L, S,I, A,P, depending on orientation

Working problem: Linked controls in Slicer3

Goals

Slice viewing can operate in the context of a single slice reformation or in a linked state where multiple slice viewers respond to interactions with any slice viewer. When Slice Viewers are linked, a number of viewing geometry and view representation parameters are linked across viewers.
