We present two illustrative experimental studies showing how non-verbal cues can both interfere and facilitate communication when passing a message to a user in HRI. In the first study, participants found that the cues enabling them to discriminate between two conditions : permissive or authoritative robots were mainly verbal. The verbal message was however unchanged between these two conditions and in this case, non-verbal cues of communication (gestures, posture, voice tone and gaze) substituted the neutral verbal message. The second study highlights the fact that verbal and non-verbal communication can facilitate the understanding of messages when combined appropriately. This study is based on a Stroop task of identifying the colour of the LEDs of a robot while the robot says words that are either facilitating, neutral or disturbing for the participant.

The capacities and usefulness of companion robots is nowadays a reality. These robots that are now more efficient, are however not accepted yet in home environments as the worth having such robots and companionship hasn’t been established. Classically, social robots were displaying generic social behaviours and not taking into account inter-individual differences. More and more work in Human-Robot Interaction goes towards the personalisation of the companion. Personalisation and control of the companion could lead to better understanding of the robot’s behaviour. Proposing several ways of expression for companion robots playing roles would allow user to customize their companion to their social preferences.\r\nIn this work, we propose a plasticity framework for Human-Robot Interaction. We used a Scenario-Based Design method to elicit social roles for companion robots. Then, based on the literature in several disciplines, we propose to depict variations of behaviour of the companion robot with behavioural styles. Behavioural styles are defined according to the social role with non-verbal expressive parameters. The expressive parameters (static, dynamic and decorators) allow to transform neutral motions into styled motions. We conducted a perceptual study through a video-based survey showing two robots displaying different styles allowing us to evaluate the expressibility of two parenting behavioural styles by two kinds of robots. We found that participants were indeed able to discriminate between the styles in terms of dominance and authoritativeness, which is in line with the psychological theory on styles in general. Most importantly, we found that the styles preferred by their parents for their children were not correlated to their own parental practice. Consequently, behavioral styles are relevant cues for social personalisation of the companion robot by parents.\r\nA second experimental study in a natural environment involving child-robot interaction with 16 children showed that parents and children were expected a versatile robot able to play several social role. This study also showed that behavioural styles had an influence on the child’s bodily attitudes during the interaction. Common dimensions studied in non-verbal communication allowed us to develop measures for child-robot interaction based on data captured with a Kinect2 sensor.\r\nIn this thesis, we also propose a modularisation of a previously proposed affective and cognitive architecture resulting in the new Cognitive, Affective Interaction Oriented (CAIO) architecture. This architecture has been implemented on the ROS framework, allowing it to be used on social robots. We also proposed instantiations of the Stimulus Evaluation Checks of [Scherer, 2009] for two robotic platforms allowing dynamic expression of emotions. Both behavioural style frameworks and the CAIO architecture can be useful in socialisation\r\nof the companion robots and improving their acceptability.", "year": 2015, "uri": "http://iihm.imag.fr/publication/J15a/", "id": 843, "note": "Thèse de Doctorat en Informatique de l'Université de Grenoble", "abbr": "J15a", "authors": { "1": { "first_name": "Wafa", "last_name": "Johal" } }, "date": "2015-10-30", "document": "http://iihm.imag.fr/publs/2015/JOHAL_BENKAOUAR_These.pdf", "type": "Thèses et habilitations", "pages": "1-196", "type_publi": "these" }, { "lang": "en", "type_publi": "icolcomlec", "doi": "http://dx.doi.org/10.1109/ROMAN.2014.6926393", "title": "Toward Companion Robots Behaving with Style", "abstract": "Sociability of companion robots is one of the challenges that the field of human-robot interaction faces. Inspired from research in psychology and sociology dealing with inter-personal relationships, we aim to render robots capable of a behaviour compatible to be among humans. In the context of a companion robot for children, we propose different parenting styles (namely authoritative and permissive) and evaluate their effectiveness and acceptability by parents. We implemented behaviours of different styles played out by two robots, Nao and Reeti, with body and facial channels respectively for communication. 94 parents watched videos of the robots and replied to a questionnaire about the authoritativeness, effectiveness and\r\nacceptability of the robots. The results showed that robots can be perceived as dominant and authoritative; however their effectiveness as an authoritative figure is limited to young children and is correlated to the style played when giving an order. When given a choice between authoritative styles, the\r\nparents ended up not always choosing a parenting style similar to their own.
