“…The technological challenge for open VE and VE involving multiple users is to provide surround ambient sound that dynamically matches with the user spatial location and can serve as a multidimensional information cue (Raghuvanshi and Lin, 2007;Kapralos et al, 2008;Verron et al, 2010;Mehra et al, 2015;Yang et al, 2022a;Liang et al, 2023).…”

Digital immersive technologies have become increasingly prominent in clinical research and practice, encompassing medical communication and technical education, serious games for health, psychotherapy, and interfaces for neurorehabilitation. The worldwide effervescence of digital health and digital therapeutics has prompted the development and testing of numerous applications and interaction methods. Nevertheless, the lack of consistency in the approaches and the peculiarity of the constructed environments contribute to an increasing disparity between the eagerness for new immersive designs and the long-term clinical adoption of these technologies. Several challenges emerge from the collide of virtual environment designers and clinicians. This article seeks to examine the utilization and mechanics of medical immersive interfaces based on extended reality and highlight specific design challenges. The transfer of virtually acquired skills and clinical efficiency is frequently constrained by a combination of perceptual and attractiveness factors. We argue that a multidisciplinary approach to development and testing, along with a comprehensive acknowledgement of the shared mechanisms that underlie immersive training, are essential for the sustainable integration of extended reality into clinical settings. The present review discusses the application of a multilevel sensory framework to extended reality design, with the aim of developing brain centred immersive interfaces tailored for therapeutic and educational purposes. Such a framework must include broader design questions, such as the integration of digital technologies into psychosocial care models, clinical validation, and related ethical concerns. We propose that efforts to bridge the virtual gap should include mixed methodologies and neurodesign approaches, integrating user behavioural and physiological feedback into iterative design phases.

Triboelectric nanogenerators (TENGs) combine contact electrification and electrostatic induction effects to convert waste mechanical energy into electrical energy. As conventional devices contribute to electronic waste, TENGs based on ecofriendly and biocompatible materials have been developed for various energy applications. Owing to the abundance, accessibility, low cost, and biodegradability of biowaste (BW), recycling these materials has gained considerable attention as a green approach for fabricating TENGs. This review provides a detailed overview of BW materials, processing techniques for BW‐based TENGs (BW‐TENGs), and potential applications of BW‐TENGs in emerging bioelectronics. In particular, recent progress in material design, fabrication methods, and biomechanical and environmental energy‐harvesting performance is discussed. This review is aimed at promoting the continued development of BW‐TENGs and their adoption for sustainable energy‐harvesting applications in the field of bioelectronics.

Augmented Reality (AR) involves the combination of synthetic and real stimuli, not being restricted to visual cues. For the inclusion of computer-generated sound in AR environments, it is often assumed that the distance attenuation model is the most intuitive and useful system for all users, regardless of the characteristics of the environment. This model reduces the gain of the sound sources as a function of the distance between the source and the listener. In this paper, we propose a different attenuation model not only based on distance, but also considering the listener orientation, so the user could listen more clearly the objects that they are looking at, instead of other near objects that could be out of their field of view and interest. We call this a directional attenuation model. To test the model, we developed an AR application that involves visual and sound stimuli to compare the traditional model versus the new one, by considering two different tasks in two AR scenarios in which sound plays an important role. A total of 38 persons participated in the experiments. The results show that the proposed model provides better workload for the two tasks, requiring less time and effort, allowing users to explore the AR environment more easily and intuitively. This demonstrates that this alternative model has the potential to be more efficient for certain applications.
