“…By displaying a variety of dynamic gestures and expressions, emotions such as joy, anger, sadness and happiness are conveyed through body language. This vivid form of expression allows users to more intuitively feel the information (Mathis et al, 2021) and emotions conveyed by the virtual avatar (Yicong and Xin, 2020), thus deepening their emotional recognition and affection for the virtual avatar, encouraging them to leave comments, share them with other people, pay attention to the subsequent updates, and deepen their impression of the video, thereby consolidating their knowledge learning. Based on the above analysis, this paper proposes the following hypotheses: H7: Virtual avatar expressiveness has a positive effect on learning effect; H8: Virtual avatar expressiveness has a positive effect on emotional experience; H9: Virtual avatar expressiveness has a positive effect on user engagement.…”

(1) Background: popularization of knowledge is of considerable importance and necessity, and traditional knowledge popularization activities suffer from high cost and low acceptance, which affect their effectiveness and coverage. Applying virtual avatars to educational videos may be an effective way to solve the problem. This study investigates the impact of applying virtual avatars to educational videos on user experience; (2) Methods: constructed a model of the impact of user experience on educational videos with virtual avatars, collected data from the target population, and analyzed it empirically; (3) Results: the video quality and virtual avatar expressiveness dimensions of the influencing factors have a significant positive effect on the learning effect, emotional experience and user engagement dimensions of user experience; the content quality dimension of the influencing factors has a significant negative effect on the three dimensions of user experience; (4) Conclusions: the video quality and virtual avatar expressiveness dimensions of the influencing factors have a significant positive effect on the learning effect, emotional experience and user engagement dimensions of user experience; the content quality dimension of the influencing factors has a significant negative effect on the three dimensions of user experience.

“…games or a collaborative assignment should be further explored to explore the effect of the task on Reality Anchors. Finally, our built VR scenes used digital avatars to represent other passengers, as previous research has shown that increased fidelity is not necessary to convey presence [41], yet further work is needed to explore impromptu interactions between passengers as they typically naturally occur when in transit situations and could not be effectively simulated by digital avatars.…”

Immersive technologies allow us to control and customise how we experience reality, but are not widely used in transit due to safety, social acceptability, and comfort barriers. We propose that cues from reality can create reference points in virtuality, which we call Reality Anchors, will reduce these barriers. We used simulated public transportation journeys in a lab setting to explore Reality Anchors using speculative methods in two studies. Our first study (N=20) explored how elements of reality like objects, furniture, and people could be used as anchors, demonstrating that visibility of other passengers and personal belongings could reduce barriers. Our second study (N=19) focused on journey types that emerged from the first study - self-managed vs. externally managed journeys - revealing that self-managed journeys increased the need for anchors. We conclude that Reality Anchors can reduce concerns associated with immersive technology use in transit, especially for self-managed journeys.

“…There have been a few previous attempts to evaluate co-presence levels when interacting with a virtual human in various XR environments. As a representative research result, Mathis et al explored the perception of virtual humans in virtual environments, and they presented the impact of virtual human's fidelity with respect to interaction [30]. According to another study, Slater et al conducted an experiment in which participants responded appropriately to a negative or positive virtual audience, and the result showed virtual humans are more effective when perceived as humans [31].…”

Recently, artificial intelligence (AI)-enabled virtual humans have been widely used in various fields in our everyday lives, such as for museum exhibitions and as information guides. Given the continued technological innovations in extended reality (XR), immersive display devices and interaction methods are evolving to provide a feeling of togetherness with a virtual human, termed co-presence. With regard to such technical developments, one main concern is how to improve the experience through the sense of co-presence as felt by participants. However, virtual human systems still have limited guidelines on effective methods, and there is a lack of research on how to visualize and interact with virtual humans. In this paper, we report a novel method to support a strong sense of co-presence with a virtual human, and we investigated the effects on co-presence with a comparison of display and interaction types. We conducted the experiment according to a specified scenario between the participant and the virtual human, and our experimental study showed that subjects who participated in an immersive 3D display with non-verbal interaction felt the greatest co-presence. Our results are expected to provide guidelines on how to focus on constructing AI-based interactive virtual humans.
