There are many search and browsing tasks online where
relevance scores are not particularly important to the
user, but other scores like popularity or average rating
can be very informative. If and how these scores are
shown varies widely between systems. In this paper, we
investigate dierent methods for visualizing these scores
and how they aect user behavior. We conducted a con-
trolled study with 21 subjects who each completed tasks
with six dierent visualization methods. We found that
there was no signicant dierence between the meth-
ods with respect to their impact on the user interaction
with search results, but that there was a strong prefer-
ence for having some sort of visualization. We discuss
the experiment, results, and design implications that
follow from this work.
The HCIL has a long, rich history of transforming the experience people have with new technologies. From understanding user needs, to developing and evaluating these technologies, the lab's faculty, staff, and students have been leading the way in HCI research and teaching.
