The original WebWisdom JavaScript Shared Browser used "self-defining" pages which defined lots of useful information including
-
Thumbnail Image location
-
URL's of Preceding Foils (for student)
-
URL's of Following Foils (for teacher)
|
JSSB uses heuristics to determine similar information under user control. It looks at page DOM to find Image URL's which look as though they form a sequence such as
-
.../img001.jpg ../img002.jpg
|
This heuristic works for Family Photos supplied by online photo processors, PowerPoint web export, WebWisdom generated pages etc.
