Casual Leisure Examples
Much like the desire to pass time at the television, we saw
many examples (some shown in Table 3) of people passing
a

time typically associated with the ‘browsing’ keyword. 5
h
1) ... I’m not even *doing* anything useful... just browsing
eBay aimlessly...
f
2) to do list today: browse the Internet until fasting break o
time.. S
3) ... just got done eating dinner and my family is watch-
ing the football. Rather browse on the laptop

4) I’m at the dolphin mall. Just browsing. b

Table 3: Example tweets where the browsing activ- d
ity is need-less. f
t
From the collected tweets it is clear that often the inform- s
ation-need in these situations are not only fuzzy, but typi- W
cally absent. The aim appears to be focused on the activity, t
where the measure of success would be in how much csmax@swan.ac.uk

curtail exploration when it is not appropriate.
4.2 Exploring for the experience
are we covering these?
Mostly related to the exploration of a novel physical space,
we saw many people exploring with family and friends. The
aim in these situations (see Table 5) is often not to find
specific places, but to spend time with family.
1) exploring the neighbourhood with my baby!
2) What a beautiful day to be outside playing and explor-
ing with the kids:)
3) Into the nineties and exploring dubstep [music] while
handling lots of small to-dos

Table 5: Example tweets where the experience out-
weighs the things found.

In these cases, the goal may be to investigate or learn
about the place, but the the focus of the activity is less
on the specific knowledge gained than on the experience it-

Casual-Leisure Search
(Deﬁnition v0.1)

• the information found is secondary to the experience

• success != ﬁnding something

• usually - the motivators are hedonistic

• an information need is often absent


Casual-Leisure Search - A New Model
In forthcoming book ‘New Directions in Information Behaviour’
Edited by Spink et al


Is this important?

• They are often lengthy, aimless, and very exploratory

• Technology is increasingly pervasive - casual-leisure
search is on the increase

• These searches are often linked to health and well-being


Is it important?

• It impacts the way we might evaluate exploratory search

• It impacts the way we might measure success

• We will struggle to design good exploratory
systems if we focus on building knowledge and forget these
casual search scenarios


• now think about the design of amazon

• now think about the design of ebay...

• now think about the design of wikipedia...


On-going Work

• Pilot studies

• Comparison of leisure and work queries in wikipedia

• Analysis of 2-days self-directed user logs
