User Experience in Virtual Environments

1. Introduction

This Special Issue offers a comprehensive examination of extended reality (XR) technologies across various contexts and domains [1,2,3]. It highlights research focused on advancing user interaction and experience in XR environments, addressing technological challenges and enhancing application efficacy across various fields [4,5,6,7].

2. An Overview of Published Articles

The first theme discussed within this Special Issue is the enhancement of object placement accuracy in AR applications [8]. This is achieved through the development and implementation of advanced algorithms for integrating virtual objects within real-world coordinates, crucial for applications requiring seamless interaction between real and virtual components. Techniques such as semantic segmentation are employed to minimize localization errors, thereby improving the fidelity of AR experiences and ensuring a more realistic integration of virtual objects into physical spaces.

Research on combating social isolation among the elderly using VR technology represents another aspect of this issue [9,10]. The studies presented on this topic focus on the design of VR environments that are not only functional, but also cater to the emotional and aesthetic needs of older adults. This approach leverages VR’s potential to facilitate the improvement of social interactions and community engagement, thus enhancing the quality of life for this demographic.

This issue also explores the design of VR spaces that enable synchronous, co-located collaboration [11,12,13]. This research is significant for fields such as education and gaming, where collaboration is integral. The studies presented on this topic outline essential design considerations that promote effective teamwork and communication within VR environments. These considerations guide the development of VR applications that support complex, real-time collaborative tasks, enhancing user engagement and efficacy in collaborative settings.

Further, this issue addresses the use of AR in e-commerce, focusing on consumer interactions with virtual try-on technologies [14,15]. By examining factors that influence consumer confidence and satisfaction, such as fit assurance and perceived value, the research presented on this topic aims to optimize AR applications for retail environments. These insights are pivotal for developing AR tools that enhance user engagement and decision-making processes in online shopping scenarios.

Advancements in the precision of 3D reconstructions are also covered in this issue, with one study exploring enhanced 3D camera localization for ear model reconstruction using specially designed caps that do not obstruct the ear [16]. Experimentation with different cap textures demonstrated reduced localization errors, with sparse dot and knitted patterns proving most effective. This research contributes to improving the accuracy and feasibility of 3D ear modelling.

3. Conclusions

A human-centric approach to XR design is emphasized in the research presented within this issue. This perspective ensures that XR technologies are developed with a primary focus on real user needs and usability, making advanced technologies more accessible and effective for a wider user base. This approach is crucial for ensuring that XR applications are not only technologically advanced, but also align with user expectations and preferences.

Overall, these studies illustrate the diverse applications of AR and VR technologies for enhancing user experience and improving technical functionalities across different fields. They demonstrate the ongoing evolution of these technologies and their growing impact on both consumer and specialized applications, providing valuable insights into their potential for future development and integration into everyday life and professional settings.
