Abstract:Subtle phenomena rooted in our body dynamics affect the reactive and evolutive parts of every human interaction. The authors' decision model allows for adaptive physical interactions between a human and a virtual agent. This article presents an evaluation of that model in terms of agent believability, the user's feeling of co-presence, and overall game experience. The results show that the model can generate adaptive body behavior for virtual agents that is comparable to a human's, but the user and agent roles… Show more

Virtual reality technology involves computer graphics, artificial
intelligence, network, sensor technology and many other aspects. It can use
the powerful computing and graphics processing capabilities of computers to
provide alternatives to the original and express its visual, tactile, and
auditory technical means. According to archaeological research data And
documentary records, virtual reconstruction and simulated display of the
cultural heritage that has been wiped out. "Digital protection" of cultural
heritage is a new way of protection, relying on computer technology, and the
use of digital equipment to collect, save, process, output and disseminate
the required information, including databases established on computer
systems, So as to achieve the purpose of information sharing and
dissemination. This article mainly studies the application research of
virtual reality technology in the digital preservation of cultural heritage.
Create an immersive environment for users, display the objects realistically
in the virtual reality system, thereby digitizing the technical protection
of cultural heritage; secondly, use the virtual environment model of
material cultural protection to build and use the terrain to generate and
edit The device imitates the terrain of the natural world to achieve its
position and the effect of being in it. Finally, the radial basis function
is used to calculate the value in the virtual environment, so that the
digital preservation of cultural heritage is more accurate. Experimental
data shows that 35.54% and 64.46% of users are more likely to use the handle
to interact with three-dimensional objects. They believe that the speed of
the handle has changed and the control is more precise. Experimental results
show that: The virtual environment reality technology specification is more
efficient than the original technology in the process of digitizing cultural
heritage.

“…For example, "How would you rate the helpfulness of the agent?" These questions were adapted from prior work on embodied agents [8,14,28]. We also asked participants to rate how likely they would recommend the agent to a friend (recommendation) and how willing they would be to interact with the agent again (continued use) to get a general sense of user acceptance/satisfaction.…”
Prior work has shown that embodiment can benefit virtual agents, such as increasing rapport and conveying nonverbal information. However, it is unclear if users prefer an embodied to a speech-only agent for augmented reality (AR) headsets that are designed to assist users in completing real-world tasks. We conducted a study to examine users' perceptions and behaviors when interacting with virtual agents in AR. We asked 24 adults to wear the Microsoft HoloLens and find objects in a hidden object game while interacting with an agent that would offer assistance. We presented participants with four different agents: voice-only, non-human, full-size embodied, and a miniature embodied agent. Overall, users preferred the miniature embodied agent due to the novelty of his size and reduced uncanniness as opposed to the larger agent. From our results, we draw conclusions about how agent representation matters and derive guidelines on designing agents for AR headsets.

“…For example, paired with real-time eye tracking, virtual characters have been used to study contingent gaze behaviors ( Wilms et al., 2010 ). Impressively, a study showed that advanced computer algorithms were able to evoke similar subjective perception in participants based on their interactions with a virtual agent as when the virtual agent was controlled by an operator in a different room, suggesting the feasibility and reliability of virtual stimuli in studying contingent actions ( Bevacqua et al., 2017 ). Although it is challenging to generate realistic avatars with contingent behaviors in complex social scenarios, some successful attempts have been made to study bystander effect ( Slater et al., 2013 ) and obedience to authority in a virtual Milgram paradigm ( Cheetham et al., 2009 ).…”
In order to understand ecologically meaningful social behaviors and their neural substrates in humans and other animals, researchers have been using a variety of social stimuli in the laboratory with a goal of extracting specific processes in real-life scenarios. However, certain stimuli may not be sufficiently effective at evoking typical social behaviors and neural responses. Here, we review empirical research employing different types of social stimuli by classifying them into five levels of naturalism. We describe the advantages and limitations while providing selected example studies for each level. We emphasize the important trade-off between experimental control and ecological validity across the five levels of naturalism. Taking advantage of newly emerging tools, such as real-time videos, virtual avatars, and wireless neural sampling techniques, researchers are now more than ever able to adopt social stimuli at a higher level of naturalism to better capture the dynamics and contingency of real-life social interaction.
