“…The results align with recent experiments where greater visual and behavioural realism engenders increased user satisfaction (Kang and Watt 2013) and likeability (Nunamaker et al 2011). The significant improvement in the Hubble comprehension scores when the agent was expressive could be explained as improved learning when there is greater overlap or redundancy of verbal and visual cues (Nunamaker et al 2011).…”

BackgroundTwo experiments investigated the effect of features of human behaviour on the quality of interaction with an Embodied Conversational Agent (ECA).MethodsIn Experiment 1, visual prominence cues (head nod, eyebrow raise) of the ECA were manipulated to explore the hypothesis that likeability of an ECA increases as a function of interpersonal mimicry. In the context of an error detection task, the ECA either mimicked or did not mimic a head nod or brow raise that humans produced to give emphasis to a word when correcting the ECA’s vocabulary. In Experiment 2, presence versus absence of facial expressions on comprehension accuracy of two computer-driven ECA monologues was investigated.ResultsIn Experiment 1, evidence for a positive relationship between ECA mimicry and lifelikeness was obtained. However, a mimicking agent did not elicit more human gestures. In Experiment 2, expressiveness was associated with greater comprehension and higher ratings of humour and engagement.ConclusionInfluences from mimicry can be explained by visual and motor simulation, and bidirectional links between similarity and liking. Cue redundancy and minimizing cognitive load are potential explanations for expressiveness aiding comprehension.Electronic supplementary materialThe online version of this article (doi:10.1186/s40469-016-0008-2) contains supplementary material, which is available to authorized users.

“…Kang and Watt (2013), for example, have demonstrated that psychological co-presence of an avatar and interactant satisfaction are increased with greater avatar anthropomorphism. Nunamaker et al (2011) demonstrated that, among other things, smiling agents were judged as more likeable.…”

“…Additional manipulations include the length of the interaction and the degree of contingent behavior within the interaction. The effectiveness of these manipulations could influence copresence, which could be measured both during and after the interaction (Kang & Watt, 2013).…”

“…Abstract-looking characters can be perceived as more credible and more socially attractive than somewhat human-looking characters (Nowak, 2004). Comparisons using realistic human characters are rarer and typically had either conflicting results or methodological limitations: conflicts between subjective and objective measures (Raij et al, 2007), uncontrolled visual differences between the human and the virtual double (Kang & Watt, 2013;MacDorman et al, 2010), a focus on realtime interactivity instead of photorealism (Kang & Gratch, 2010), or the exclusion from comparison of a human reference (McDonnell, Breidt, & Bülthoff, 2012). To address limitations in previous research, this study directly compared a human character with a photorealistic double.…”

Just as physical appearance affects social influence in human communication, it may also affect the processing of advice conveyed through avatars, computer-animated characters, and other human-like interfaces. Although the most persuasive computer interfaces are often the most human-like, they have been predicted to incur the greatest risk of falling into the uncanny valley, the loss of empathy attributed to characters that appear eerily human. Previous studies compared interfaces on the left side of the uncanny valley, namely, those with low human likeness. To examine interfaces with higher human realism, a between-groups factorial experiment was conducted through the internet with 426 midwestern U.S. undergraduates. This experiment presented a hypothetical ethical dilemma followed by the advice of an authority figure. The authority was manipulated in three ways: depiction (digitally recorded or computer animated), motion quality (smooth or jerky), and advice (disclose or refrain from disclosing sensitive information). Of these, only the advice changed opinion about the ethical dilemma, even though the animated depiction was significantly eerier than the human depiction. These results indicate that compliance with an authority persists even when using an uncannily realistic computeranimated double.

Part 1: Information & Communication Technology-EurAsia Conference 2014, ICT-EurAsia 2014International audienceAs the landscape around Big data continues to exponentially evolve, the « big » facet of Big data is no more number one priority of researchers and IT professionals. The race has recently become more about how to sift through torrents of data to find the hidden diamond and engineer a better, smarter and healthier world. The ease with which our mobile captures daily data about ourselves makes it an exceptionally suitable means for ultimately improving the quality of our lives and gaining valuable insights into our affective, mental and physical state. This paper takes the first exploratory step into this direction by using the mobile to process and analyze the “digital exhaust” it collects to automatically recognize our emotional states and accordingly respond to them in the most effective and “human” way possible. To achieve this we treat all technical, psycho-somatic, and cognitive aspects of emotion observation and prediction, and repackage all these elements into a mobile multimodal emotion recognition system that can be used on any mobile device
