“…However, with the recent leap in the quality of reconstructed 3D VH, it is important to understand how these new levels of visual realism can impact the perception of VHs. For instance, recent results with more visually realistic VHs suggest that visual realism affects empathic responses to VHs [HZCM23]. Subramanyams et al [SLVC20] investigated also in the geometrical features impacting the realism of 3D point‐cloud VHs.…”

Generating realistic animated virtual humans is a problem that has been extensively studied with many applications in different types of virtual environments. However, the creation process of such realistic animations is challenging, especially because of the number and variety of influencing factors, that should then be identified and evaluated. In this paper, we attempt to provide a clearer understanding of how the multiple factors that have been studied in the literature impact the level of realism of animated virtual humans, by providing a survey of studies assessing their realism. This includes a review of features that have been manipulated to increase the realism of virtual humans, as well as evaluation approaches that have been developed. As the challenges of evaluating animated virtual humans in a way that agrees with human perception are still active research problems, this survey further identifies important open problems and directions for future research.

“…However, approaching a human-like virtual replica implies some risk, as users may face the uncanny valley [34] when interacting with the avatar. High fidelity characters ended up being considered more attractive, less disturbing, more human and more cheerful than their low fidelity counterparts [35].…”

Interactive technologies, such as mixed-reality and natural interactions with avatars, can enhance cultural heritage and the experience of visiting a museum. In this paper, we present the design rationale of an interactive experience for a cultural heritage place in the church of Roncesvalles at the beginning of Camino de Santiago. We followed a participatory design with a multidisciplinary team which resulted in the design of a spatial augmented reality system that employs 3D projection mapping and a conversational agent acting as the storyteller. Multiple features were identified as desirable for an interactive experience: interdisciplinary design team; in-situ; mixed reality; interactive digital storytelling; avatar; tangible objects; gestures; emotions and groups. The findings from a workshop are presented for guiding other interactive cultural heritage experiences.

“…This means that lower quality avatars are less uncanny, but to convey the same emotional intensity they have to be more exaggerated, consequently leading to high uncanniness. MetaHumans created in Unreal Engine 4 have achieved very low uncanny feelings by combining high fidelity models with motion capture [16], therefore breaking a key barrier to virtual agents. A significant application of facial emotion research has been the development of interventions to improve the social cognition and skills of participants.…”

Currently, accurate representation of physical spaces and, especially, human interactions in Virtual Reality (VR)can often feel clunky, unrealistic and require specialist knowledge and development. Our project explores avatar use through the Unreal Meta Humans tool (an extraordinary new 3D character creation technology), specifically, testing the use of realistic avatars in soft skills training and social interactions. This is a proof-of-concept project to generate ideas that address this gap in knowledge, do fast, low-cost prototyping and user testing to further our understanding of the field. We built and tested the recognition of basic emotions in Meta Humans and cartoon avatars in VR. The aim was to understand whether the realism of the avatar impacts our perception of basic human emotion and the sense of immersion in VR. This work aims to advance the study of artificial social interactions, and guide industry practice.
