ProSPer: a MOST model extension applied to persuasive interactive system

Abstract: Developing persuasive interactive system faces the challenge of describing multiple-domain goals to be achieved, along with an context-aware driving of persuasion. We developed ProSPer, a model capable of dealing with this challenges and we implemented two experiments using an Android application and a selfmonitoring bracelet. The preliminary results shows that participants understood and applied effectively the model, giving further design prospectives of research and development.

Real-time perception of non-verbal human feedback in a gaming scenario

Abstract: Social interactive robots require sophisticated perception and cognition abilities to behave and interact in a natural human-like way. The precise perception of behaviour of an interaction partner plays a crucial role in social robotics. Human feedback is one of the most important behavioural cues of human during conversation. Feedback is a signal that human sends to the interlocutor, consciously or unconsciously, that can convey four communicative functions. These functions: continuation, perception, understanding, and acceptance of the message, activate or inhibits different behaviours of human. Past systems focused mainly on the scripted scenarios irrespective of interaction partners feedback behaviour. This paper proposes a system for perception and interpretation of the interaction partner feedback from non-verbal cues. The proposed work has been tested in a 20 question gaming scenario in real time and it has shown promising results.

Interactive technology solutions for prisoners: An environment where sub-optimal user interfaces can have significant impact?

Abstract: As a work in progress, we are currently investigating if current offender technology used in prisons worldwide meets the needs of prisoners who have low computer and reading literacy. In addition to the obvious requirements of a prisoner’s persona, researchers have identified that emotions in prisons can be heightened and usability issues with technology can be disruptive and result in unwanted behavior. With this in mind, we aim to evaluate the user interfaces using validated usability testing protocols.
