In this presentation from the 2012 Games User Research Summit, I talk about physiological research methods for games and why this matters for examining user experience with physiological measures.

* Thank you, Steve!
10. Continuous Recording
• Not interrupting play
• Don’t break experience
• No memory bias
• Wearing sensors
1
11. We need a vocabulary
Measured Activities
• Motor
• Skin
• Brain
2
12. One aspect at a time
• Hypothesis-driven
• Based on literature

13. Physiological success metric
• Link between ideal
experience and physiological
responses
• Financial success games
• Critical success games

14. Context Influence
• Human body
• Real world
• Sensitivity

15. Three activity components
• External physical
• Internal emotional
• Internal cognitive

16. Noise and confounds
• Signal-to-noise ratio
• Experimental protocol
• Record with more sensors

17. Demographics
• Skill level
• Preferences

19. Record ALL the data
• Better analysis through
correlation with metrics
• Used mixed methods to
get subjective results in
addition

eXperience
• Volatile/Feeling
• Knowledge/Learning

22. Our 2 selves
“We choose between memories of experiences”
(Kahneman)
• Experiencing
• Remembering

23. Takeaway
Emotional experiences are important in games for
financial and for critical success, but most important
for memorability.
Keep in mind the complexity of physiological
recording and analysis. This approach will only yield
meaningful results if it is used correctly and with
care. There is no quick fix.
