Special Issue Information

Dear Colleagues,

Extended reality (XR) technologies combine digital and physical objects into various kinds of innovative and immersive experiences. Virtual reality (VR) blinds out physical “real reality” (RR) and replaces it with digital representations, augmented reality (AR) enhances RR with a digital layer of information and representations, and mixed reality (MR) integrates representations from both physical and digital worlds.

As all these extensions of RR aim to engage users, they depend on real-time interactions between users, physical and digital objects. Users should be able to move freely in time and space. Thus, any communication with XR devices (e.g., headsets, controls) should be wireless by nature. Remote rendering and multi-user settings may necessitate high and stable data rates, while keeping strict timing requirements in the order of milliseconds over a shared and easily disturbed medium. It is thus not surprising that VR has been one of the most challenging use cases for 5G. It is also expected that future XR technology will increasingly move from the lab into the wild, enabling truly mobile and immersive-anywhere XR experiences. However, there are still significant gaps between the demands placed on, and the capabilities of, wireless and mobile networks to cater for the needs and expectations of XR users.

This Special Issue aims to identify and reduce those gaps by providing a forum for the latest research within the field as well as multi-disciplinary studies between and beyond the following areas:

  • Evaluation of wireless XR technology from user and technical perspectives;
  • Advances in wireless XR devices;
  • Experiences with wireless XR technologies;
  • Studies of quality of experience, user experience, usability and utility;
  • Studies of quality constituents, features and underlying factors;
  • Derivation and evaluation of user mobility models;
  • Delay and data rate measurements, analyses and models;
  • Simulation- and performance-analysis-based studies;
  • Analyses of the interaction of wireless XR devices with remote computing environments (e.g., edge-, fog- or cloud-based);
  • Management of wireless XR environments;
  • Artificial intelligence (AI) support of wireless XR environments;
  • Sustainability considerations and trade-offs (e.g., regarding energy consumption).

The development of ubiquitous computing technology and the emergence of XR could provide pedestrian navigation with more options for user interfaces and interactions. In this work, we aim investigate the role of a mixed-reality map interface in urban exploration to enhance pedestrians’ mental satisfaction. We propose a mixed-reality 3D minimap as a part of the navigation interface which pedestrians could refer to and interact during urban exploration. To further explore the different levels of detail of the map interface, we conducted a user study (n = 28, two groups with two tasks). We designed two exploratory activities as experimental tasks with two map modes (a normal one and a simplified one) to discuss the detailed design of the minimap interface. The results indicated that participants showed a positive attitude toward our method. The simplified map mode could result in a lower perceived workload in both tasks while enhancing performance in specific navigation, such as wayfinding. However, we also found that pedestrians’ preference for the level of detail of the minimap interface is dynamic in navigation. Thus, we suggest discussing the different levels of detail further in specific scenarios. Finally, we also summarize some findings observed during user study for inspiring the study of virtual map interface of future mixed-reality navigation for urban exploration in various scenarios.
