“…These findings are in line with previous research [1], [10,11,12,13] and suggest that the choice of visual representation drives attributions regarding the cognitive and emotional intelligence the system invites. Given that such effects are fast, in part automatic, and might not habituate over short exposures, the design of applications should therefore take a match between the perceived profile of the agents and the intended function into account.…”

Abstract. While most interface agents have been designed from an adult perspective, the present paper compares adults' and children's views of agents that vary in their degree of humanness. Four synthetic characters ranging in appearance from non-human to very human (blob, cat, cartoon, human) were presented to adult and children perceivers and were evaluated with respect to their cognitive and emotional abilities. The visual appearance significantly influenced participants' ratings in both age groups. However, the pattern of results was more differentiated for adult perceivers as a function of the humanlikeness of the character. The findings suggest that children may rely less on human-like features in inferring agents' capabilities which are judged along simpler cognitive and social dimensions. Implications for the design of artificial agents are discussed.

“…Our character is lifelike, reproduces the human physics in detail, and performs non-verbal behaviors in an exaggerated manner as this has been proven to convey emotions more efficiently and directly than regular performance (in fact, caricaturists take advantage of this), making interaction a fun experience. Embodiment enhances entertainment and effective user engagement [14]. A preliminary system test, we recently run with eighteen 10 to 18 years old kids, seems to support these facts.…”

Abstract. This paper reports on the generation of coordinated multimodal output for the NICE (Natural Interactive Communication for Edutainment) system [1]. In its first prototype, the system allows for fun and experientially rich interaction between primarily 10 to 18 years old human users and 3D-embodied fairy tale author H.C. Andersen in his study. User input consists of domainoriented spoken conversation combined with 2D input gesture, entered via a mouse-compatible device. The animated character can move about and interact with his environment as well as communicate with the user through spoken conversation and non-verbal gesture, body posture, facial expression and gaze. The described approach aims to make the virtual agent's appearance, voice, actions, and communicative behavior convey the impression of a character with human-like behavior, emotions, relevant domain knowledge, and a distinct personality. We propose an approach to multimodal output generation, which exploits a richly parameterized semantic instruction from the conversation manager and splits the instruction into synchronized text instructions to the textto-speech synthesizer, and behavioral instructions to the animated character. Based on the implemented version of this approach, we are in the process of creating a behavior sub-system that combines the described multimodal output instructions with parameters representing the current emotional state of the character, producing animations that express emotional state through speech and non-verbal behavior.

“…By humanizing the appearance of social robots, engagement might be increased and allows users to employ social and physical conventions that are familiar to them (cf. [20,31]). Furthermore, increasing anthropomorphism leads to longer interactions with the robot and a more positive, lifelike evaluation of the robot [19].…”

In the near future, human-like social robots will become indispensable for providing support in various social tasks, in particular for healthcare (e.g., assistance, coaching). The perception of realism, in particular human-like features, can help facilitate mediated social interaction. The current study investigated the effects of form realism on engagement with and use intentions of social robot embodiments. We have defined (perceived) form realism as the result of the appraisal of features that are perceived as realistic contrasted with those appraised as unrealistic. To test the effects of form realism, we applied the model of interactively perceiving and experiencing fictional characters (I-PEFiC). I-PEFiC explains how users respond to interactive, fictional, humanoid characters, on social robots. In a within-subjects design, participants (N = 29; M age = 28.8 years, age range 18-56 years) interacted with three different robots built from LEGO Mindstorms, which differed in their degree of designed form realism. Each robot presented itself as a physiotherapy assistant and requested the participant to do several exercises. Results of a structured questionnaire indicated that form realism only played a modest role in the perception of electro-mechanical robots. Instead, the perception of affordances appeared to be crucial for determining engagement and intentions to use social robots.
