Thanks to the existing powerful immersive hardware systems, complex technical and natural systems can be digitally represented in a realistic virtual environment. This enables users to completely immerse in the virtual environment and to observe and interact with the systems and objects contained therein without major restrictions, or to augment real products and systems with digital data in runtime. This creates new opportunities to present the behaviour and functionalities of complex systems in a tangible and understandable way. Therefore, the xR technology can revolutionize learning and training methods, especially in the qualification of specialists and experts. This paper will introduce the international project “International Cooperation on VR/AR Projects” (IC xR-P). The target of “IC xR-P” is the implementation of a practice-oriented xR training applications in the areas of medical training, rescue and Knowledge transfer in schools and universities and their testing and evaluation with selected experts. “IC xR-P” is an international cooperation between the University of Applied Sciences Karlsruhe from Germany, University of Applied Sciences Turku from Finland and the Higher Institute of Computer Science and Multimedia Sfax from Tunisia. Among the learning projects in the ICxRP, we focus in this paper on the implementation of VR training apps for medical training in this paper, we centred on the Perception of Memory Impairment in Alzheimer’s Patients. Patients with early Alzheimer’s disease may have spatial and time-oriented disorders. The objective is to use immersion in a virtual environment. This allows the user to experience a multisensory experience during which the user can feel and interact naturally and intuitively in real time via sensory interfaces. VR offers different levels of interaction, from the minimum level where the subject remains passive, looking at the environment, to more interactive levels where the subject is active, controlling its movement to the first person in the virtual environment via various interaction tools immersive.Within this project a VR-Training App will be designed and implemented, which fulfill the following functions with different virtual games facilitating the communication of the patient with the virtual environment. This application can develop the creating immersion and feeling of presence in patients. Also, we propose Family/Entourage Show service, it’s a memory stimulation exercise by integrating the family photos. We propose in addition a VR creation of patients’ usual living environment (home, hallway, bedroom…). We improve the valuing specific objects and places in the house to facilitate the orientation and the exploration of the environment.

Currently, most adaptive systems apply either active or passive data collection for building an adaptive virtual environment. The goal of the current research is to identify an optimal methodology for integrating both active and passive data into an adaptive virtual environment that can employ user data for fine tuning stimulus presentations.

Indeed, IVR allows researchers to place participants in realistic three-dimensional environments with a level of control that may not have been feasible in physical environments. Additionally, IVR elicits a higher sense of presence than computer-based interventions. Evidence suggests that presence, defined as the “sense of being there”, is a key factor in the success of these interventions. The relationship between presence and hardware and software factors have been extensively investigated. Behavioral factors have comparatively received little attention. While these system factors are important to investigate, behavioral differences across users may preclude them from engaging in meaningful IVR interventions, regardless of the hardware and software solutions applied. Therefore, this study investigated how an individual’s interaction with the virtual experience may influence their sense of presence. More specifically, we wanted to probe the relationship between environment-activated motion (EAM) and presence in IVR. EVM can be described as any motion within the experience initiated by the user or the environment. This is activated by user-activated motion (i.e., a user looks around) or environment-activated motion (i.e., a virtual dog moves within view). 80 younger adults (22 male, 1 non-binary) completed a 10-minute IVR experience in Vesper Peak using the HTC Vive IVR system. The experience consisted of playing with a virtual robot dog (ex., petting and playing fetch) and teleporting to different areas of the mountain. The session was screen captured using OBS. EVM data were collected by analyzing the videos via OpenCV’s implementation of Dense Optical Flow (DOF). Presence was collected via the IGroup Presence Questionnaire (IPQ, Cronbach’s ⍺ = 0.87). Five data were removed due to corruption, resulting in a final sample size of 75. A regression was conducted with EVM as the predictor and presence as the predictand. The overall model was non-significant (R2 = 0.04, RSE = 5.87, F(1,73) = 12.61, p = 0.054). These results suggest that environment-activated motion may not play a significant role in presence during IVR experiences. Future IVR-based interventions may not have to control for environment-activated motion and can focus more on user interaction and environment design. Further research is needed to look into how environment-activated motion and user-activated motion separately may affect presence in different ways.","PeriodicalId":389727,"journal":{"name":"Human Factors in Virtual Environments and Game Design","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127685784","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the accelerated development of artificial intelligence and technology, technology has brought new vitality and vitality to the dissemination of intangible cultural heritage. This study is based on augmented reality technology and uses interactive AR technology to design and practice the problems and challenges in the inheritance of intangible cultural heritage. Digitally transforming traditional Chinese Chaoju culture, breaking through traditional presentation methods, not only achieves the revitalization of intangible cultural heritage, but also strengthens the convenience of dissemination. The article first discovers the current inheritance issues of intangible cultural heritage through research, questionnaires, and literature research, and summarizes the current status of intangible cultural heritage dissemination technology. Then, the application and advantages of AR technology in the dissemination of intangible cultural heritage were explored. Through existing case studies, the design methods and principles of AR technology intervention were analyzed, and the application forms of AR technology in the design of intangible cultural heritage dissemination were sorted out. The direction and direction of design practice were proposed. Finally, taking the Chinese Chaozhou Opera culture as an example, the design practice was verified. Through field visits and questionnaires, the researchers deeply explored the current living conditions and communication difficulties of Chaozhou Opera, and grasped the pain points of Chaozhou Opera communication. After a series of analysis and summary, the cultural elements of Chaozhou Opera are extracted, and interpreted with Chinese traditional Paper Cuttings technology, forming a three-dimensional picture book. Then, based on user experience theory, considering the dimensions of visual presentation, functional attributes, and interactive experience, Chaoju characters are interacted with users in the form of augmented reality through an app. This includes an introduction to the history and culture of Chaozhou Opera, as well as interactive features of Chaozhou Opera characters, enhancing users' interactivity, entertainment, and participation in experiencing intangible cultural heritage. In the design practice, it has explored a new path for the dissemination of Chinese Chaozhou Opera culture, laid a foundation for the development of its digital path, and also verified the design orientation of augmented reality technology in the dissemination of intangible cultural heritage, as well as its advantages and necessity for the dissemination of intangible cultural heritage.

To this end, recent research has explored the use of affective brain-/body-computer interfaces to monitor such factors [2, 3]. Typically, studies have been conducted in laboratory settings and have relied on research-grade neurophysiological sensors. Transferring the obtained knowledge to everyday settings, however, is not straightforward, especially since it requires cumbersome and long preparation times (e.g., placing electroencephalography caps, gel, test impedances) which could be overwhelming for gamers. To overcome this limitation, we have recently developed an instrumented “plug-and-play” virtual reality head-mounted display (termed iHMD) [4] which directly embeds a number of dry ExG sensors (electroencephalography, EEG; electrocardiography, ECG; electromyography, EMG; and electrooculography, EoG) into the HMD. A portable bioamplifier is used to collect, stream, and/or store the biosignals in real-time. Moreover, a software suite has been developed to automatically measure signal quality [5], enhance the biosignals [6, 7, 8], infer breathing rate from the ECG [9], and extract relevant HIFs from the post-processed signals [3, 10, 11]. More recently, we have also developed companion software to allow for use and monitoring of the device at the gamer’s home with minimal experimental supervision, hence exploring its potential use truly “in the wild”. The iHMD, VR controllers, and a laptop, along with a copy of the Half-Life: Alyx videogame, were dropped off at the homes of 10 gamers who consented to participate in the study. All public health COVID-19 protocols were followed, including sanitizing the iHMD in a UV-C light chamber and with sanitizing wipes 48h prior to dropping the equipment off. Instructions on how to set up the equipment and the game, as well as a google form with a multi-part questionnaire [12] to be answered after the game were provided via videoconference. The researcher remained available remotely in case any participant questions arose, but otherwise, interventions were minimal. Participants were asked to play the game for around one hour and none of the participants reported cybersickness. This paper details the obtained results from this study and shows the potential of measuring HIFs from ExG signals collected “in the wild,” as well as their use in remote gaming experience monitoring. In particular, we will show the potential of measuring gamer engagement and sense of presence from the collected signals and their influence on overall experience. The next steps will be to use these signals and inferred HIFs to adjust the game in real-time, thus maximizing the experience for each individual gamer.References[1] Perkis, A., et al, 2020.

Stamm, Susan Vorwerg, Kai Kruschel, Kristain Hildebrand","doi":"10.54941/ahfe1002071","DOIUrl":"https://doi.org/10.54941/ahfe1002071","url":null,"abstract":"Human interactions with the trainer during physical training can be highly engaging and motivating [1] and are based on rapport as a dynamic structure of mutual attentiveness and coordination [2]. Human-Agent interaction in virtual reality (VR) aims to establish interaction patterns and rapport with virtual agents similar to real life. Research shows that users react towards virtual agents similar to real people [3] and that rapport is established similar to human rapport [4]. Therefore, rapport with virtual trainers in exergames is used to enhance an engaging and motivating user experience.In this paper we report on the results from an evaluation study on perceptions and interactions with the virtual trainer “Anna” after a 6-week exergame training for senior patients with hypertension. The human-like “Anna” is the key element of interaction design in a gamified series of exergames developed in the bewARe project. Anna was developed as a realistic, full body, female figure (silhouette) to motivate participation in the VR training. The primary goal of our research was to evaluate to what extent senior users can establish rapport with the virtual trainer as a factor contributing to positive user experience and training outcomes. The evaluation was conducted with 23 participants aged 65 and older with diagnosed hypertension. The virtual trainer Anna facilitated user participation in both exergames by giving instructions, modeling movements and providing feedback during the exergames in the HTC Vive Pro Headset. We used the 15-item rapport scale by [5] to measure rapport. The study also applied further research instruments to explore perceptions of the virtual trainer such as the trait list with 9 items describing selected features of the virtual trainer, and the bipolar uncanniness questionnaire with 40 adjectives used to assess possible Uncanny Valley effects described by [6]. The results of the rapport scale indicate that the design of the virtual trainer was effective for establishing rapport especially in terms of building a relationship with the virtual trainer and enhancing the engagement of senior users to participate in the VR training. However, the design was less effective in creating a positive perception of the trainer as a warm, caring and respectful agent. The overall median of the rapport scale was 6 (Min:1,Max:8). The results of the evaluation of the trait list revealed that voice quality, speech pauses and bodily movements were rated highest, followed by head and hand movements. The lowest values were researched for face expression. In the Uncanny Valley questionnaire, the median value for the humannes scale was 1 (Min:-3,Max:3), for the attractiveness 1 (Min:0,Max:3) and for the eeriness 0 (Min:-1,Max:0). Furthermore, the paper explores the relationships between the rapport scores and the perception of senior trainees of selected characteristics of the virtual agent and the uncanniness scale.
