3. UX in the long term: an important but
neglected issue (1)
While the importance of temporality has been
repeatedly highlighted in user experience research, it
has rarely been systematically addressed.
…Due to the effort involved in conducting longitudinal
studies.
or a lack of sufficient interest, induced by a belief that
motivating prolonged use does not necessarily lead to
increased commercial revenues.
4. UX in the long term: an important but
neglected issue (2)
2 Main Trends that highlight the importance of long term UX
(Karapanos et al. 2010):
Products are becoming service-centered.
products sold for lower prices, and thus revenues are mainly coming
from the supported service.
prolonged use therefore has a direct impact on the revenues of a
company.
Time and coverage of product warranty increases due to
legislation and competition enforcement.
An increasing number of users tend to complain about the
experiential aspects of products that go beyond the out-of-the-box
experience
6. Context of the study
Based on:
Moschou, E. and Zaharias, P. UX-Curve revisited;Assessing
long-term user experience of MMOGs. In CHI 2013Workshop
on Games User Research, (2013).
Why long term UX in MMOGs?
Shortage of relevant studies so far
Players usually have a long lasting relationship with the game
they play
The main objective of the study:
To investigate, understand and interpret the changes of players’
experience over time
7. The method: A new version of UX Curve
UX Curve: A retrospective method for assessing long
term UX proposed by Kujala et al. (2011).
Based on drawings made by users
Cost efficient as a long term usage can be
covered in a single session
Results give an overview of the most
relevant experiences
Memories are as important or more than
actual experiences
9. Towards a new version of UX Curve
The game: League of Legends
The players: 9 students aged between 18-20 years old
who had been playing LoL for periods ranging from 6 to
16 months (mean: 12.5 months SD: 3.1 months)
The new version of UX Curve:
UX Curve
• General UX
• Attractiveness
• Ease of use
• Utility
• UsageVolume
UX Curve (MMOG
version)
• General UX
• Degree of usage
• Ease of use
• Immersion
• Social interaction
• Engagement
10. Indicative results (1)
A total of 54 curves were collected. Most of the curves
were improved revealing thus an increasing user
experience
General UX Curve for each user ID The immersion UX Curve for each user ID
11. Indicative results (2)
In order to draw the curves, players described the factors
that improved their experience over time or caused it to
deteriorate

12. Indicative results (3)
All except for two “Ease of use” curves were improving
or stable, with pragmatic-related reasons to be the most
frequent.
most negative perceptions related to usability and utilities
reasons
Overall, most of the issues influencing the long-term user
experience in the game were related to non-pragmatic
issues such as fun, immersion, challenge, interest and
control.
13. Key Takeaways
It is crucial to measure UX in the long term
Retrospective methods can greatly help in understanding
how UX changes over time
Memories are as or more important than actual
experiences
UX Curve is a cost efficient and effective method to use
for analyzing and understanding long term UX
The new proposed version of UX Curve (adjusted for
gaming environments) seems to be a valid and effective
method for assessing long term UX of MMOG players
It can be applied to many other contexts for evaluating
products/services/systems
