Quantitative measures of gameplay experience
• Physiological responses
• Behaviour metrics
• Questionnaires
• Logging

10 ideas to make physiological
user research meaningful for you*
* Thank you, Steve!
Continuous Recording
• Not interrupting play • Don’t break experience • No memory bias • Wearing sensors
1
We need a vocabulary
Measured Activities
• Motor
• Skin
• Brain
2

One aspect at a time • Hypothesis-driven • Based on literature
3
Physiological success metric • Link between ideal
experience and physiological responses
• Financial success games • Critical success games

Context Influence • Human body • Real world • Sensitivity

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

Noise and confounds • Signal-to-noise ratio • Experimental protocol • Record with more sensors
7

Demographics • Skill level • Preferences
8

Experiment conditions • Systematic changes • Start with one variable
9
Record ALL the data • Better analysis through
correlation with metrics • Used mixed methods to
get subjective results in addition

Still with me?
Ok, a word about UX!
User eXperience
• Volatile/Feeling
• Knowledge/Learning
Kahneman’s
memory of experiences
Peak-end rule
End of event more important for encoding of experience

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

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.
