“…Behavioral realism can also be influenced by a number of factors, including behavioral appropriateness (Bailenson, Blascovich, Beall, & Loomis, 2003), behavioral accuracy (Wang, Khooshabeh, & Gratch, 2013), voice quality (Lee, 2010), non-verbal behavior (e.g. nodding, gestures) (von der Pütten et al), gaze behavior (Garau et al, 2003), and facial/emotional expressions (Rickel & Johnson, 2000).…”

“…Despite this range of methods, usually the measurement of human behavior with respect to perception, action and task-performance are involved [23]. Many of the presented studies deal with visual perception of scenes presented in VREs [3,8,36,37]. Thompson et al have for instance investigated whether the quality of the displayed graphics in a virtual world affects the estimation of distances [37].…”

Throughout the years, many shading techniques have been developed to improve the conveying of information in volume visualization. Some of these methods, usually referred to as realistic, are supposed to provide better cues for the understanding of volume data sets. While shading approaches are heavily exploited in traditional monoscopic setups, no previous study has analyzed the effect of these techniques in virtual reality. To further explore the influence of shading on the understanding of volume data in such environments, we carried out a user study in a desktop-based stereoscopic setup. The goals of the study were to investigate the impact of well-known shading approaches and the influence of real illumination on depth perception. Participants had to perform three different perceptual tasks when exposed to static visual stimuli. 45 participants took part in the study, giving us 1152 trials for each task. Results show that advanced shading techniques improve depth perception in stereoscopic volume visualization. As well, external lighting does not affect depth perception when these shading methods are applied. As a result, we derive some guidelines that may help the researchers when selecting illumination models for stereoscopic rendering.Peer ReviewedPostprint (published version

“…Studies exploring the influence of voice found that computer-synthesized voices were perceived less favourably than human voices, with the emphasis placed on words, and pauses between words, improving student learning in a pedagogical agent situation (Clark & Mayer, 2008). Furthermore, split-attention effect (Garau et al, 2003), in which students experience a higher cognitive load due to competing demands for their attention, occurred when students felt an agent's voice and appearance did not match and were therefore distracted from the learning activity at hand. The impact of split-attention affect is significant; it reduces the believability and, consequently, willingness to trust the agent (Demeure et al, 2011).…”

Online chatbots (also known as pedagogical agents or virtual assistants) are becoming embedded into the fabric of technology, both in educational and commercial settings. Yet understanding of these technologies is inchoate and often untheorised, influenced by individuals' willingness to trust technologies, aesthetic appearance of the chatbot and technical literacy, among other factors. This paper draws upon data from two research studies that evaluated students' experiences of using pedagogical agents in education using responsive evaluation. The findings suggest that emotional connections with pedagogical agents were intrinsic to the user's sense of trust and therefore likely to affect levels of truthfulness and engagement. They also indicate that the topic of the pedagogical agent-student interaction is key to the student's experience. The implications of these studies are that truthfulness, personalisation and emotional engagement are all vital components in using pedagogical agents to enhance online learning.
