Towards Customized Emotional Design: an Explorative Study of User Personality and User Interface Skin Preferences
Willem-Paul Brinkman Nick Fine
Topics Research Motivation
Study 1: Explorative study into
personality and skin
preferences
Study 2: Exploring initial findings
with a specific set of skins
Conclusions & Future Research
Research MotivationWhy considering emotion in design?
“First, someone who is relaxed, happy, in a pleasant mood, is more creative, more able to overlook and cope with minor problems with a device - especially if it’s fun to work with….Second, when people are anxious, they are more focused, …, designer must pay special attention to ensure that all the information required to do the task is continually at hand, readily visible, with clear and unambiguous feedback about the operations that the device is performing.”
(Norman, 2004, p.26)
Research Motivation
• Emotion, Aesthetics, Fun, Self-image all Highly Personal
• Segmenting user population?
Research Motivation
Segmentation based on: Personality
traits Gender Age etc
Personality traits: “dimensions of individual differences in tendencies to show consistent patterns of thoughts, feelings, and actions” (McCrae and Costa, 2003)
Example of dimensions of individual differences are Neuroticism, Extraversion, Openness, Agreeableness, Conscientiousness.

Study 1: Method Focus on skin
selection Often users scan
through a list of potential skins and select one
Selection is less based on interaction experience, but more on previous knowledge, taste and expectation.
Study 1: Method Material Measures Participants Procedure
Windows Media Player Randomly selected 61 skins from
set of 178 downloaded from the internet
4 screen shots of each skin
Study 1: Method Material Measures Participants Procedure
Intention of selecting a specific type of skin“I would try this skin on my media player”
BIS/BAS scales: Motivation towards something desirable and undesirable (Carver and White , 1994)
IPIP-NEO Big-5 Model: extraversion, agreeableness, conscientiousness, neuroticism, and openness to experience (Buchanan, Johnson, and Goldberg, 2005).

likely
Study 1: Method Material Measures Participants Procedure
99 students and staff of School Computing, Information Systems, and Mathematics (Brunel University)
58 males, 35 females, 6 unspecified
Age between 18 and 52 years. Median 20 years
Study 1: Method Material Measures Participants Procedure
Class Room Setting
Slides projected on large screen
Participants were first show complete set (reduce learning effect)
Next, set was shown again and participants rate each skin
Example
I would try this skin on my media player. Unlikel
yLikely
Please rate the statement for the previous skin (1)
I would try this skin on my media player. Unlikel
yLikely
Please rate the statement for the previous skin (2)
Study 1: Method Material Measures Participants Procedure
Skins shown in sets of 10
Afterwards participants completed BIS/BAS scale (24 questions) Done in the class room
Participants were asked to complete IPIP-NEO inventory online and return the results afterwards 120 questions Only 17 participants return results
Study 1: Results
Factor Analysis
Did participants use limited number of dimensions to rate the skins?
Standardized Skin rating: z-score transformation per participant
Principal component as factor extraction method
19 components explaining 0.74 of overall variance
Examining varimax rotated component matrix
No clear interpretation of components
Study 1: Results
Correlation with Gender
Females were more in favour of :
Charming, ‘cute’ characters
Study 1: Results
Correlation with BIS/BAS
BAS: Drive
Participants more driven by pursuit of desired goals :
Over-powering, dark vs light or bright
Participants less driven by pursuit of desired goals :
Study 1: Results
Correlation with BIS/BAS
BIS
High on motivation of avoiding undesirable situations :
Blue
Low on motivation of avoiding undesirable situations :
Study 1: Results
Correlation with IPIP-NEO
Similarity-Attraction
Participants select skins with represent similar personalities (adoption of Nass and Reeves’ hypothesis)
friendliness
Not-cheerfulness
Not-neuroticism, Not-vulnerability
Study 1: Results
Correlation with IPIP-NEO
Similarity-Attraction
Participants select skins with represent similar personalities (adoption of Nass and Reeves’ hypothesis)
Depression, Self-consciousness (neuroticism)
Immoderation, excitement-seeking
Study 1: Results
Correlation with IPIP-NEO
Colour?
Extraversion, assertiveness
Gregariousness, not-anxiety, not-
anger
Neuroticism, anxiety
Not-assertiveness
Not-activity level
Study 1: Conclusions and Limitations
Potentially links such as gender and skin themes Personality and colour Similarity-attraction hypothesis
Very Preliminary Conclusions Post-hoc analysis (large number of
correlations examined) Small sample size (IPIP-NEO) Interpretation very subjective and lot of
confounding variables
Study 2: Method
Material Measures Participants
Selecting or designing 4 skins for 17 categories
1. Blue skins2. Purple/violet skins3. Grey skins4. Bright skins5. Colourful skins6. Large, dark skins7. Small skins8. Medium size, squared
shape skins9. Complex interaction skins
10. Small and friendly creature
11. Friendly, charming ‘baby’ character
12. Humoristic skins13. Action theme skins14. Predator skins15. Scary skins16. Mildly scary skins17. Standard skins
Study 2: Method
Material Measures Participants
Skins shown in sets of 17
Afterwards participants completed: reduced version of BIS/BAS scale
(15 questions) reduced version IPIP-NEO (48)
questions (only extraversion and neuroticism)
Study 2: Method
Material Measures Participants
130 Undergraduates Computer science and Information System course
83 male, 44 female, and 3 unspecified
Age: between 18 and 49 years, median 21 years.
Study 2: Results
Designing for similarity or diversity
Highest mean rating (4.85)
25% participants gave the skin their highest rating
mean rating (4.84) 35% participants
gave the skin their highest rating
Study 2: Results Analysing
category rating
Internal consistency
Positive correlations between rating within skin categories
1. Blue skins2. Purple/violet skins3. Grey skins4. Bright skins5. Colourful skins6. Large, dark skins7. Small skins8. Medium size, squared
shape skins9. Complex interaction skins
10. Small and friendly creature
11. Friendly, charming ‘baby’ character
12. Humoristic skins13. Action theme skins14. Predator skins15. Scary skins16. Mildly scary skins17. Standard skins
Study 2: Results
Correlation with age
Older participants were more in favour of Grey skins
Younger participants were more in favour of humoristic skins
Study 2: Results
Correlation with gender
Female participants were more in favour of
Friendly, charming ‘baby’ character
Small and friendly creature
Study 2: Results
Correlation with gender
Males were more in favour of
Small skins
Predator skins
Medium size, squared shape skins
Scary skins
Study 2: Results
BIS scale High on motivation of avoiding undesirable situations :
Colourful skins
Friendly, charming ‘baby’ characters
Study 2: Results
Similarity-attraction
Colourful skins negative correlation with gregariousness
Action theme positive correlations cheerfulness
Humoristic theme positive correlation cheerfulness, negative correlation depression
Study 2: Results

Regression lines for skin rating from BAS-Drive scale

Dependent variable: skin rating
Independent variable

Study 2: Conclusions and limitations
Again found links such as gender and skin themes Personality and colour Similarity-attraction hypothesis
Still Very Preliminary Conclusions Interpretation skins is still subjective
(observers interpretation)
Future work
Repeat study Participants also rating skins on “skin
dimensions” such “how humoristic would you rate this skin?”
Design new skins specific for categories Systematic manipulation of skins
Extending the model
