- PublicationOpen AccessSeniors’ Sensing of Agents’ Personality from Facial Expressions(Springer Verlag, 2018)
; ; ; ; ; ; ; ; ; ;; ; ;The presented study investigated the preferences of seniors towards artificial avatars showing personality both from a pragmatic and a hedonic point of view. Also, preferences for technological devices were considered. The involved participants were 45 adults (20 female) aged 65+ years in good health. They were asked to watch video clips of 4 agents (two males and two females) showing different personality traits (i.e. angry, depressed, joyful, and practical), and subsequently had to complete a questionnaire. Subjects were not informed about an avatar’s personality and not openly interviewed regarding this subject. Rather, the administered questionnaire was devoted to test their perception of agents and whether such complies with the intended characteristics. Results show that subjects prefer female agents with a positive personality (joyful and practical) on both pragmatic and hedonic dimensions of the interactive system.114 106 - PublicationOpen AccessElder user’s attitude toward assistive virtual agents: the role of voice and gender(2021-04)
; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; This paper reports on experiments devoted to explore the role of specific attributes of humanoid virtual agents that may influence elderly users’ perception and attitude, determining their acceptance and adoption as assistive devices. In particular, it investigates elderly preference on agents’ gender and the role of the agents’ ability to use voice during the interaction. To this aim two different groups of seniors were involved in the experiments. The first group evaluated talking virtual agents, the second one the same virtual agents, but silenced. The data shows that elderly users, independently from their gender, prefer to interact with female agents, especially when they are able to talk to them, revealing the role played by the voice. Furthermore, it was found a significant effect of the elderly level of experience with technology: when interacting with agents with voice, elderly users with high technological experience were less interested and considered the proposed agents less attractive and appealing, while just the opposite occurred when interacting with silenced agents.115 80
