“…An important component of many remote laboratories is an interactive live-stream provided by a web camera (e.g., [12], [59], [60]). While in a hands-on laboratory users observe through their own eyes, in a remote laboratory they do this through this camera and use that information to interact with the lab.…”

Online remote laboratories are a particularly promising tool for effective STEM education. They offer online universal access to different hardware devices in which students can experiment and can test and improve their knowledge. However, most of them have two significant limitations. First, given that most of them are developed as, or evolve from single-user proofs of concept, they have no scalability provisions other than full laboratory replication. And second, when this is done, cost efficiency is often neglected. This paper presents the requirements for the creation of a novel remote laboratory architecture focused on, but not limited to, embedded systems experimentation. An architecture, based on Redis (an open source, in-memory data structure store, which is often used as database, cache or message broker), a modular design, and hardware-sharing techniques, is proposed in order to achieve the combined requirements of high scalability and cost efficiency. This mixed hardware-software architecture serves as a basis for the development of remote laboratories, especially those focused on microcontroller-based systems experimentation and embedded devices experimentation. From a user perspective the architecture is webbased, and has provisions to be easily adaptable to different Learning Management Systems and different hardware embedded devices. A new microcontroller-oriented remote laboratory based on the architecture has been developed, with the aim of providing valid evaluation data, and has been used in a real environment. The architecture and the resulting remote laboratory have been compared with other state of the art remote laboratories and their architectures. Results suggest that the proposed architecture does indeed meet the main requirements, which are scalability through replicability and cost efficiency. Furthermore, similarly to previous architectures, it promotes usability, universal access, modularity and reliability.

“…There are several studies regarding augmented reality based distance laboratory systems (Andujar et al, 2011;Frank & Kapila, 2017;Maiti et al, 2018;Onime & Abiona, 2016;Vargas et al, 2013). Vargas et al (2013) see AR as an innovative path to enriching visualization in distance laboratories for engineering education. Andujar et al's (2011) augmented remote laboratory (ARL) system stands out when research on virtual and distance laboratories and augmented reality is parsed.…”

The Usability of Augmented Reality in Open and Distance Learning Systems: A Qualitative Delphi Study

2019

View full text Add to dashboard Cite

The main purpose of this research is to determine the usability of augmented reality in open and distance learning environments in accordance with universal design principles, and to make predictions for the future by gathering expert opinions on this subject using the Delphi technique. The Delphi technique was applied to 14 expert participants for 3 rounds as the primary data collection tool with open ended questions based on the theoretical framework. Structured interview questions were used as a secondary data collection tool and were applied during an academic exchange in China. In the Delphi technique used as the primary data collection tool, 92 themes were evaluated by experts and accepted as usability principles by end of this research. Therefore, 92 themes under 21 titles were presented for the use of augmented reality within the framework of universal design principles in open and distance learning. This research may be the first unique study on the usability of augmented reality not just as the convergence of this technology with open and distance learning environments but also incorporating the learning and communication dimensions of this convergence, thereby contributing to the literature of the field. It is imperative to determine the usability of augmented reality in open and distance learning, along with the “how” of this use in application. In this regard, the findings of this study are significant in shedding light to the enrichment, diversification and increased interaction of open and distance learning environments in accordance with universal design principles, bringing a new perspective to how a different technology convergence may be conducted, providing further accessibility.

Interactive live streaming is a key feature of applications and platforms in which the actions of the viewers affect the content of the stream. In those, a minimal capturedisplay delay is critical. Though recent technological advances have certainly made it possible to provide web-based interactive live-streaming, little research is available that compares the real-world performance of the different web-based schemes. In this paper we use educational remote laboratories as a case study. We analyze the restrictions that webbased interactive live-streaming applications have, such as a low delay. We also consider additional characteristics that are often sought in production systems, such as universality and deployability behind institutional firewalls. The paper describes and experimentally compares the most relevant approaches for the study. With the provided descriptions and real-world experimental results, researchers, designers and developers can: a) select among the interactive live-streaming approaches which are available for their real-world systems, b) decide which one is most appropriate for their purpose, and c) know what performance and results they can expect.
