• more familiar interface metaphor
  • web 2.0 "social" interaction
  • posting/sharing
• moves the burden of maintenance away from end user
• allows for mobile

• Some viewers that you can use. Right now
   
• A workflow manager that you can use. Right now, too.

• Simple, single-purpose
  • Show static information: text and/or images
  • Provide single-focus dynamic data
• Complex, integrative, but still generically single-purpose
  • Facebook
  • Twitter
  • Mobile: instagram, snapchat, whatsapp, etc...

Web apps...

are

• Accessible from anywhere!
  • Desktops, Laptops
  • (Smart) Phones
  • Tablets
• Are "simple"
  • require little end user maintenance
  • just go to a link
• but...
  • Are typically not as "powerful" as traditional client apps.

How to view images...

... easily?

• Cornerstone (Chris Chafey)
• SliceDrop
• MedView

• allows for advanced view rendering
• allows for sharing of images
• allows for immersive real time collaboration
• allows for post-processing of images

• collect
• manage
• analyze
• view
• collaborate

• ChRIS instance

• seamlessly connect to standard PACS with Query/Retrieve
• direct access to server filesystem
• drag-n-drop from local client into server
• ssh/scp underpinning for secure network transfers

• all "data" is stored in a time-based feed
• feeds are basically file-browsers
• feeds can be annotated with free form notes
• shared feeds can support comments between parties

• a "plugin" mechanism offers the ability to accept feed data and process data
• ChRIS is usually configured to communicate transparently with an HPC
• plugins are mostly non-interactive analysis pipelines
• interactivity is available as a pre-processing step

• image data in feed can be viewed directly in simple drop down window
• image data can be viewed in more sophisticated fashion with specialized viewing modes
• advanced sharing using 3rd party backends (Google Real Time API / Dropbox API)

• image data can be shared between collaborators
• Google RealTime API
• a realtime JSON object is shared and updates each viewer independently
• (akin to multi-player games)
• shared screen components (like cursor)
