- In this demo, we will showcase a platform we are currently developing for experimenting with situated interaction using mixed reality. The user will wear a Microsoft HoloLens and be able to interact with a virtual character presenting a poster. We argue that a poster presentation scenario is a good test bed for studying phenomena such as multi-party interaction, speaker role, engagement and disengagement, information delivery, and user attention monitoring.

- We present a demonstration system for psychotherapy training that uses the Furhat social robot platform to implement virtual patients. The system runs an educational program with various modules, starting with training of basic psychotherapeutic skills and then moves on to tasks where these skills need to be integrated. Such training relies heavily on observing and dealing with both verbal and non-verbal in-session patient behavior. Hence, the Furhat robot is an ideal platform for implementing this. This paper describes the rationale for this system and its implementation.

Learning and reusing dialog for repeated interactions with a situated social agent

Konferensbidrag (refereegranskat)abstract
- Content authoring for conversations is a limiting factor in creating verbal interactions with intelligent virtual agents. Building on techniques utilizing semi-situated learning in an incremental crowdworking pipeline, this paper introduces an embodied agent that self-authors its own dialog for social chat. In particular, the autonomous use of crowdworkers is supplemented with a generalization method that borrows and assesses the validity of dialog across conversational states. We argue that the approach offers a community-focused tailoring of dialog responses that is not available in approaches that rely solely on statistical methods across big data. We demonstrate the advantages that this can bring to interactions through data collected from 486 conversations between a situated social agent and 22 users during a 3 week long evaluation period.

- A brief display of facial features based behavior has a majorimpact on personality perception in human-human communications.Creating such personality traits and representations in a social robot isa challenging task. In this paper, we propose an approach for a roboticface presentation based on moveable 2D facial features and present acomparative study when a synthesized face is projected using three setups;1) 3D mask, 2) 2D screen, and 3) our 2D moveable facial featurebased visualization. We found that robot’s personality and character ishighly influenced by the projected face quality as well as the motion offacial features.

Does a robot tutee increase children’s engagement in a learning-by-teaching situation?

Konferensbidrag (refereegranskat)abstract
- This paper presents initial attempts to combine a humanoid robot with the teachable agent approach. Several design choices are discussed, including the decision to use a robot instead of a virtual agent and which behaviours to implement in the robot. A pilot study explored how the interaction with a robot seemed to influence children’s engagement as well as their attribution of mental states to a robot and to a virtual agent. Eight children participated and the interaction was measured via an observational protocol and a conversational interview. A main outcome was large individual differences between the children’s interaction with the robot compared to the virtual agent.

The expression of mental states in a humanoid robot

Konferensbidrag (refereegranskat)abstract
- We explore to what degree movement together with facial features in a humanoid robot, such as eyes and mouth, can be used to convey mental states. Several animation variants were iteratively tested in a series of experiments to reach a set of five expressive states that can be reliably expressed by the robot. These expressions combine biologically motivated cues such as eye movements and pupil dilation with elements that only have a conventional significance, such as changes in eye color.

Lay causal explanations of human vs. humanoid behavior
- 2017

Ingår i: Proceedings of the 17th International Conference on Intelligent Virtual Agents. - Cham : Springer. - 9783319674018 - 9783319674001 ; , s. 433-436

Konferensbidrag (refereegranskat)abstract
- The present study used a questionnaire-based method for investigating people's interpretations of behavior exhibited by a person and a humanoid robot, respectively. Participants were given images and verbal descriptions of different behaviors and were asked to judge the plausibility of seven causal explanation types. Results indicate that human and robot behavior are explained similarly, but with some significant differences, and with less agreement in the robot case.
