Special Issue on Next-Generation Mixed-Reality User Experiences: Training, Teaching, and Learning

The future is bright and challenging: we envision a very complex combination of mixed reality (MR), artificial intelligence, and spatial computing as a smart integration of interconnected systems—seamlessly bridging both physical and virtual spaces. The upcoming generation of everyday wearable, embedded, and ubiquitous technology allows the ideation and validation of a wide range of next-generation context-aware, or intelligent MR user experiences. Realization of this vision is promising, especially given recent interdisciplinary advancements in key areas and growing interest in applying novel approaches in real-world application domains. This Special Issue aimed to attract ambitious contributions addressing this intelligent vision for MR leveraging, new computational interfaces, spatial computing, rich and diverse data sources, smart devices’ extensive computation power, artificial intelligence, and sensing capabilities, as well as ubiquitous connectivity, computation resources, and storage offered by the existing communication and network infrastructure. We sought contributions that addressed new methods, technologies, approaches, applications, case studies, and industrial showcases, paving the way for novel insights, breakthrough designs, discussions, and developments in this rapidly evolving domain.
