###### Abstract
The metaverse is highlighted as a transformative force for fashion brands, offering new engagement and commerce opportunities but also introducing challenges like potential addiction and misinformation risks. Key recommendations include developing platform-specific marketing and SEO strategies tailored to each audience. The scope was limited to Google Trends and two keywords, suggesting the need for broader future research on other platforms and with more keywords. On the other hand, another paper [6] examines cybersecurity, privacy, and confidentiality challenges in Mixed Reality and metaverse environments. Key risks include data breaches, authentication issues, and threats to user anonymity due to sensitive data exchange. The authors review secure design, encryption, multi-factor authentication, and regulations to mitigate vulnerabilities; their recommendations focus on data protection, transparency, user consent, security updates, and privacy compliance. The study highlights the need for ongoing research to counter evolving threats and stresses the importance of robust security frameworks for building trust and enabling the safe adoption of MR and metaverse technologies. This Special Issue also contains papers directly related to VR and augmented reality (AR). Regarding VR, the paper [7] compares university professors' perceptions of VR as an educational tool both in Latin American countries that are members of CABEI and those that are not, based on a questionnaire administered to 1246 educators. Professors from CABEI countries rated VR usability higher and perceived fewer disadvantages, although their improvement in digital competence significantly exceeded the increase in positive VR valuation. The gap between private and public university professors was more pronounced in CABEI countries, favoring private institutions. Nevertheless, actual VR adoption remains limited, as the increase in favorable VR perception is just over 3%. The study recommends increased investment and the development of specific protocols to enhance VR integration, particularly in public universities, while acknowledging that factors beyond CABEI membership may influence these outcomes, consistent with previous studies [8]. Another study [9] evaluates the use of VR video games to teach direct current electrical circuits at a Colombian public university, employing a mixed-methods action research approach. The results show that VR significantly enhances student comprehension, motivation, and engagement compared to traditional methods, while promoting equitable access to advanced learning tools. The VR application demonstrated safety and comfort, though moderation in usage is advised. Challenges include the need for robust technological infrastructure and curriculum adaptation. The study highlights VR's potential to transform technical education and calls for further research on long-term learning outcomes and broader applicability. On the other hand, regarding AR, user perceptions of privacy protection in AR environments are examined in [10], focusing on three visual obfuscation techniques: blurring, masking, and pixelation. The survey results reveal that preferences vary by context and user demographics, with blurring favored for its aesthetics, masking viewed as most secure but less appealing, and pixelation ranked in the middle. Familiarity with AR influencesacceptance, with more experienced users preferring blurring. These findings inform the design of privacy-preserving AR applications that balance security and usability, crucial for adoption across sectors like education and healthcare. Finally, CityBuildAR--a mobile AR app--is presented in [11]. This app allows users, especially those with limited design knowledge, to visualize and contribute to public space design. Tested at the University of Moratuwa, Sri Lanka, this study found that non-professionals favored greener spaces and found the app more useful for expressing ideas compared to professionals.
