    Comparing Modalities to Communicate Movement Amplitude During Tool Manipulation in a Shared Learning Virtual Environment
    (The Eurographics Association, 2022) Simon, Cassandre; Otmane, Samir; Chellali, Amine; Hideaki Uchiyama; Jean-Marie Normand
    Shared immersive environments are used to teach technical skills and communicate relevant information. However, designing the appropriate interfaces and interactions to support this communication process remains an open issue. We explore using three modalities to communicate movement amplitude during tool manipulation tasks in a shared immersive environment. The haptic, visual, and verbal modalities were used separately to instruct a learner about the amplitude of the movements to perform in the 3D space. The user study comparing these modalities shows that instructions given through the visual modality permitted to decrease the distance estimation error. In contrast, the haptic modality helped the learners perform the task significantly faster. The verbal modality significantly increased the perceived sense of copresence but was the least preferred modality. This research contributes to understanding the importance of each modality when communicating spatial skills in a shared immersive environment. The results suggest that combining modalities could be the most appropriate way to transfer movement amplitude information to a learner by improving performance and user experience. These findings can enhance the design of immersive collaborative systems and open new perspectives for further research on the effectiveness of multimodal interaction to support learning technical skills in VR. Designed tools can be used in different fields, such as medical teaching applications.

    Could you Relax in an Artistic Co-creative Virtual Reality Experience?
    (The Eurographics Association, 2022) Lomet, Julien; Gaugne, Ronan; Gouranton, Valérie; Hideaki Uchiyama; Jean-Marie Normand
    Our work contributes to the design and study of artistic collaborative virtual environments through the presentation of immersive and interactive digital artwork installation and the evaluation of the impact of the experience on visitor's emotional state. The experience is centered on a dance performance, involves collaborative spectators who are engaged to the experience through full-body movements, and is structured in three times, a time of relaxation and discovery of the universe, a time of co-creation and a time of co-active contemplation. The collaborative artwork ''Creative Harmony'', was designed within a multidisciplinary team of artists, researchers and computer scientists from different laboratories. The aesthetic of the artistic environment is inspired by the German Romantism painting from 19th century. In order to foster co-presence, each participant of the experience is associated to an avatar that aims to represent both its body and movements. The music is an original composition designed to develop a peaceful and meditative ambiance to the universe of ''Creative Harmony''. The evaluation of the impact on visitor's mood is based on "Brief Mood Introspection Scale" (BMIS), a standard tool widely used in psychological and medical context. We also present an assessment of the experience through the analysis of questionnaires filled by the visitors. We observed a positive increase in the Positive-Tired indicator and a decrease in the Negative-Relaxed indicator, demonstrating the relaxing capabilities of the immersive virtual environment.
