Question: "Can we use keyhole plan recognition
to detect enough of a user's plan to find out if an entry or a set
of entries are interesting, or uninteresting, to that user?"
5 users, using the same mail reader, to capture search
& reading strategies
Stage 1: 2 users and verbal protocol method
Stage 2: Record user behavior (silent)
Stage 3: Production of HTA
Observations:
Even for experimenters, difficult to recognize when
something was interesting
(Time taken scanning not necessarily a factor)
However, identification of non-interesting items
more readily apparent
(Non-selection)
