Draft Description of User Interaction (for discussion)


(Jon Thaler) #1

Draft Description of User Interaction
This is copied from the November 13, 2015 meeting notes, to make it more visible.
Some comments are there.
March 8, 2016: THis document has been moved to Google Docs, to simplify editing and commentary.

Starting up:

  • From the command line (with an optional image identifier), or
  • Double-click an app icon.

What the user sees at startup:

  • FF image display window.
    If no image was specified, display a text message, or perhaps a clickable link to the image browser or to help.
  • FF tool bar. Will we need another, or is FF configurable?
    *Command line window, with a short message (e.g., “Type ’help’ for help.”)
  • One “results” window ??

Windows should be resizable. Should each user have a profile, with defaults?

What the user can do after startup:

  • Get help. The interface should be as standard as possible.
    Perhaps a downloadable or interactive tutorial?
  • Get an image:
  • Via browser. There may be more than one image library.
  • Via URL or other specifier.
  • Multiple image displays, separate or overlaid, must be allowed.
  • Open or close “results” windows.

With an image (or two) on the display:

  • Manipulate the image display

  • Pan, zoom, contrast (transfer function). If two images, do the same to both (if desired).

  • Image comparison: Subtraction, blink, etc.

  • Masking (e.g., of known bad spots).

  • Live (real-time) display of pixel values and hardware regions.

  • Modify the pixel aggregation algorithm (to modify zoom behavior)

  • Select regions of interest

  • Hardware regions.

  • User definable (e.g., circle or square selected from toolbar)

  • Send commands (with parameters) to the server

  • Examples of parameters:
    . The ROI
    . Min/max pixel values to process.

  • Commands must give intelligible error messages (e.g., wrong # parameters)

  • The user should be able to specify the output window.

  • Command types:
    . Region statistics (variance, etc.)
    . Pixal lists (e.g., hot/dead)
    . Image comparisons (ratios, differences, etc.)
    . Generate documentation:
    . Save command results to files (on server or client)
    . Write annotations.
    . Save image files (eg, jpeg).
