“…After this introduction, the participants were provided with the HMD and invited to enter a VE depicting a theater 7 , where they could see the actor's recorded avatar. In each scene, the participants were free to move on the stage via natural walking around the avatar to observe gestures and expressions from the preferred position (Figure 2).…”

“…They can be realistic, 4 or cartoon‐looking 5 . They can also differ in terms of complexity, 6 ranging from ergonomic and minimalist visualizations 7 in which only the user's head and hands are shown, up to configurations much closer to reality, with complete figures from head to toes 8 . The latter may be also provided with facial expressions 2 .…”

With the development of metaverse(s), industry and academia are searching for the best ways to represent users' avatars in shared virtual environments (VEs), where real‐time communication between users is required. The expressiveness of avatars is crucial for transmitting emotions that are key for social presence and user experience, and are conveyed via verbal and non‐verbal facial and body signals. In this paper, two real‐time modalities for conveying expressions in virtual reality (VR) via realistic, full‐body avatars are compared by means of a user study. The first modality uses dedicated hardware (i.e., eye and facial trackers) to allow a mapping between the user's facial expressions/eye movements and the avatar model. The second modality relies on an algorithm that, starting from an audio clip, approximates the facial motion by generating plausible lip and eye movements. The participants were requested to observe, for both the modalities, the avatar of an actor performing six scenes involving as many basic emotions. The evaluation considered mainly social presence and emotion conveyance. Results showed a clear superiority of facial tracking when compared to lip sync in conveying sadness and disgust. The same was less evident for happiness and fear. No differences were observed for anger and surprise.

“…In order to acquire the necessary skills, traditional training materials may not be fully effective, and it has been demonstrated that VR can help [30,31]. In fact, with VRTSs it is rather easy to organize hands-on exercises that simulate scenarios that could expose the trainees to potential risks, or could require expensive, rare, or fragile instrumentation, which is actually the case of the considered domain; VRTSs also allow for the adapting of the training to the trainees' actual needs, delivering continuous advice and feedback in addition to monitoring his or her progress and outcomes in an objective and repeatable way [32][33][34][35].…”

Energy Efficiency Engagement Training in SMEs: A Case Study in the Automotive Sector

Energy efficiency requirements in Europe are set by the Energy Efficiency Directive, considering energy audits as a systematic procedure to determine the savings in energy costs. These kinds of tools provide useful information for companies to identify opportunities for the improvement of their energy performance. However, the regulation is only applied for non-SMEs in Europe, which make up only 0.2% of the total number of European companies. Compared in terms of the value added or the number of employees, these companies are still at a lower percentage than small and medium enterprises. The wide versatility of small companies, however, makes it difficult to determine a regulation that promotes the objective of the Directive in a uniform way. For this reason, one aspect that is being worked on with small companies is raising awareness and training in energy aspects, encouraging them to carry out activities to improve their energy performance based on their own initiative. In this regard, within the framework of an H2020 research project based on the automotive sector, the E2DRIVER project, a collaborative–cooperative training methodology has been designed to motivate and empower the key actors within a company. This paper describes the methodology and its implementation in different companies in European countries, providing some representative results.
