Special Issue Information

Dear Colleagues,

Extended reality (XR) is a term used to refer to mixed reality (MR) technology that encompasses both virtual reality (VR) and augmented reality (AR). The applications of XR are emerging in everyday life through the use of immersive technologies that can merge the physical and virtual worlds. Although XR has been flourishing in fields such as education, gaming and entertainment, it is becoming critical in other fields and practices for its ability to visualize a completed project in advance and demonstrate how to control and manage it based on sound simulation or avatars that can interface with actual systems. Fortunately, the XR tools can provide detailed and thorough plans and schematics –– these allow owners, managers and designers to observe a full functioning project in detail before the actual system can be built. Although XR faces some limits, the advancement of useful tools and algorithms from artificial intelligence, location information, and automatic translation technologies means that we are witnessing superior capabilities that will open future doors for creating innovative systems. This Special Issue focuses on studies related to XR applications and management systems. We are interested in submissions that utilize a variety of methodological perspectives and welcome both original research and review articles.

All topics related to XR applications and management systems are welcome, especially in the fields of business, education, health and medical care, social science and the humanities. Additionally, all topics related to the development of XR are welcome, especially, IT and computing, artificial intelligence, big data and engineering.

Material structures and chemical equilibrium are important learning units in high school chemistry. In this study, an augmented reality (AR) system is developed to assist high school students in learning chemistry. Students can use AR cards to conduct virtual chemistry experiments, and the submicroscopic view of a chemical reaction will be displayed according to the chemical equation specified by the reactants and coefficients on AR cards. They can change the AR cards to observe the experimental results and obtain the simplest integer ratio in a chemical equation. It is helpful for understanding that a chemical reaction changes the composition of reactants to form new products and that the process obeys the law of conservation of mass. Empirical research has been conducted in which the experimental group used the AR system and the control group used the traditional teaching method for learning chemistry. The analytical results show that the AR system is more effective than the traditional teaching method, especially for low-achievement students. The questionnaire results indicate that the learning motivation of the experimental group was slightly higher than that of the control group, and the cognitive load was slightly lower than that of the control group, both without achieving a significant difference.

To solve the problems exposed by the application of blockchain technology under complex scenarios, such as fraudulent use of data, hard to store huge amounts of data, and low traceability efficiency under an ultra-huge number of traceability requests, this paper constructs an image-based interactive traceability structure by using images as an enhancement. By adding pointers to raw image files, a specific file structure is formed for traceability, and the traceability process is separated from the verification process, therefore realizing the distributed traceability of “traceability off the chain and verification on the chain”. The experimental results show that, compared with the traditional blockchain traceability mode, the interactive traceability structure can reduce the data retrieval pressure and greatly improve the traceability efficiency of a specific transaction chain. With the growth of the span of the transaction chain, the traceability efficiency advantage of the interactive traceability structure becomes more obvious. Full article

Augmented reality (AR) technology has rapidly developed in recent years. This technology is widely used in various fields, including museum exhibitions, where people use it to experience art in a new way. While AR aims to realize the interaction between the virtual world and the real world, museums use AR to develop new digital artwork from artifacts. When text descriptions are no longer attractive to the audience, museums need to add more sound effects to images and video dynamics to develop a sustainable way for the industry’s future. For the continued use of such technology and the better development of the museum industry, this study used a structural equation model to explore the influences on the continuance intention of museum AR technology through experiments and questionnaires. Furthermore, it established a model with six dimensions: interaction quality, information quality, information richness, satisfaction, perceived playfulness, and continuance intention. Moreover, the results of this study can serve as a reference for managers to promote the extensive application of AR technology in museum construction, thereby providing visitors with better experiences and satisfying their needs.

This study proposes Bstick, the first handheld-type haptic controller that can monitor and control the placement of five fingers in real-time using linear motors attached on the fingers. As a handheld device, it can be used with both hands, and it was designed and produced to allow it to be freely moved and used with other virtual reality (VR) devices via Bluetooth. Bstick also provides stiffness that can maintain the pressing forces of an adult man’s fingers, providing a realistic sense of grabbing and controlling a virtual object with rigidity and softness. By changing the location of the finger buttons, the device can render virtual objects of various shapes and sizes. A component that can be implemented in the Unity game engine was developed to provide convenience in the content development, using a haptic controller feature where a user can move five fingers independently, and this was applied for hand rehabilitation contents. Bstick includes five linear motors that can sustain approximately 22 N of force per finger, and the hardware and circuitry are compact, so as to be held in the user’s hand. Bstick can be used to create VR services and contents based on five-fingered force feedback using a haptic controller that can independently manage the motions of five fingers, and Unity game engine software that can modify hardware.
