7. Interaction Behaviour and User Personality Study 1  16 participants used CD player for 3 to 5 days  Completed the IPIP-NEO inventory  CD player recorded clicks with timestamp in log file  Measures:  Average number of clicks made in a day  Average time between two clicks

8. Interaction Behaviour and User Personality Results  Number of clicks made in a day  Click interval Correlated with Extraversion (.83**) assertiveness (.61*) Agreeableness trust (.54*) Conscientiousness (.56*) self-efficacy (.54*) self-discipline (.61*) *sign at a 0.05 level, **sign. at a 0.01 level

14. Conclusions and Future Research  Possibility to Determine Personality Traits from Interaction Behaviour?  User Preference for Skin Properties might be linked with User Personality Traits  Very Preliminary Conclusions  Post-hoc analysis (large number of correlations examined)  Small sample size  Future research  PROSKIN project (www.proskin.org)
