Better Image Review User Experience

In my previous post, I mentioned three aspects of image review that can be improved.  The first of these is improvements in the user experience during image review.

The increased use of image-guidance during the course of treatment represents a significant source of knowledge about the delivery, but also an additional burden on daily routines.  The subjective tedium of working through a list of images can be lightened by enhancing aspects of the review user experience.

Usability concerns that can be addressed include:
  • Color schemes that are better adjusted for visual analysis, for instance with darker colors
  • Animated transitions to facilitate visual parsing of state changes, such as pop-up toolbars and changes in image selection
  • Use of spatial layout to convey semantic relationships, as in thumbnail and carousel presentations of images in temporal succession
  • Progressive rendering and dynamic resizing of image elements, to minimize variations in the availability of network resources
Combining these techniques in a single workspace can produce a compelling user experience for image review.

A number of architectural patterns are used to support these techniques.  Examples of these patterns are contained in the PheonixRt.Mvvm prototype.
