This study presents the introduction of Arduino to undergraduate architecture students through a series of project-based exercises in two different universities. The main motivation of study is based on supporting students’ motivation, engagement, and creativity under remote education conditions in the context of digital fabrication. This research consolidates the digital fabrication pedagogy efficiency in the time of post COVID-19 using both distant and hybrid learning modes. Students have exerted a dedication effort and enjoyed digital craft especially while using Arduino despite the virtual teaching classes. Kinetic applications have received students' total endorsement and hands-on involvement supported with theoretical lectures focusing on fabrication techniques, materials and tools along with parametric algorithmic design. Assignments are both structured and semi-structured to promote their skills and grant them a free-flexible pedagogical approach.

Collaborative Mixed Reality (MR) provides a virtual/real world in which various users can interact and build virtual objects together. One of the issues in collaborative MR is permission and rights control that defines which user can access which virtual object. A user may define access rights for other users to access the virtual objects created by her/him, which might enable the other users to manipulate the existing virtual object, delete them, or even steal them. For maintaining accountability in the collaborative world, each activity of each user should be maintained against each object. Hence, an activity provenance mechanism is required for a collaborative MR environment, which can be used to identify the culprit. In this paper, a secure activity provenance mechanism for collaborative MR environments is proposed which utilizes blockchain technologies to maintain the integrity of the provenance data. The proposed scheme is implemented on a consortium blockchain using Hyperledger Fabric as a proof of concept. The presented mechanism is also evaluated using metrics throughput and latency and the results confirm that the proposed solution is best suited for maintaining accountability in a collaborative mixed reality network.

Heath data are sensitive and valuable for individuals. The patients need to integrate and manage their medical data continuously. Personal Health Record (PHR) is introduced as a solution for managing their health information. It gives patients ownership over their medical data and provides physicians with realignment data. However, it does not achieve reliability, traceability, trust, nor security of patient control. Centralization of any data is vulnerable to the problem of hacking and single failure in addition to control from one organization. So, the centralization of data is the common problem that all current healthcare systems suffer from. Even in the Metaverse world, the application of Metaverse in healthcare services loses users’ privacy as one of its challenges. In this study, we suggest using blockchain in healthcare to improve security and privacy in medical records. The proposed system employs the advantages of blockchain technology to give patients full control over their data with low throughput, high overhead, and latency. We present a security analysis of our suggested architecture as well as blockchain issues in healthcare systems.

The concept of the Metaverse has gained increasing attention as advances in virtual and augmented reality (AR) technologies have enabled the creation of immersive and interactive virtual environments. However, most of these studies remain independent and only a few studies attempted to investigate their relationships. To analyze key trends in Metaverse research and conduct a thorough bibliometric analysis, we used VOSviewer and Bibliometrix, R-tool package on the Scopus database. Our co-occurrence analysis revealed that the hot topics are related to virtual reality, augmented reality, the Internet of Things, and blockchain, and there are potential areas for future research, such as privacy, security, and education in the Metaverse. In addition, our analysis identified the most active countries and institutions in the field, the top subject areas, as well as potential gaps in the literature that could be explored in future research. This study provides valuable insights into Metaverse research and can help guide future research in this field.
