Behavior and Personality Analysis in a Nonsocial Context Dataset

Dario Dotti, Mirela Popa, Stylianos Asteriadis
2018 2018 IEEE/CVF Conference on Computer Vision and Pattern Recognition Workshops (CVPRW)  
Forty-six participants were recorded in an unconstrained indoor space, related to a smart home environment, performing six tasks resembling Activities of Daily Living (ADL).  ...  The majority of existing methods investigate personality assessment in social contexts, such as crowded places or social events, but ignore the role of behaviors as well as personality in nonsocial situations  ...  Additionally, we would like to thank all the participants in our experiment, who were students as well as employees from the University of Maastricht (The Netherlands).  ...
