In 2019, the United Nations released its 10-year policy of “ESD for 2030”. Many schools around the world have actively participated in the transformation and have included the United Nations Sustainable Development Goals (SDGs) in Education for Sustainable Development (ESD). Many developed countries hope to combine the concept of STEAM education (Science, Technology, Engineering, Art, and Mathematics) with interdisciplinary learning, and apply it to ESD. This study intended to integrate the sustainability concept into Virtual Reality (VR) system-aided STEAM education, in order to provide school children with integrated interdisciplinary STEAM education. A literature review was conducted and the research hypotheses were proposed. The empirical method and questionnaires were used as research methods to investigate the influence of the proposed system on the students’ satisfaction, self-efficacy, and learning outcomes after cognition learning. The results of this study showed that the combination of STEAM education, with VR-aided experience courses, could help to improve the learning satisfaction and outcomes of students and to arouse their learning motivation. However, the proposed system needs an ESD that is based on students’ traditional culture (such as designing a role-playing game), so that they can improve their self-efficacy through playing a VR game. Although VR games are interesting, they are difficult for some students to play. Therefore, it is necessary to adjust the teaching materials, methods, and strategies appropriately by using information technology, so that ESD can be achieved by inspiring students to explore continuously. The findings can serve as a reference for further relevant studies.

Macao is a tourist city. It is home to the Ruins of Saint Paul’s, a unique 100-year-old landmark, which is still standing with manual maintenance, even after three fires and reconstruction events. Therefore, the continuous preservation of its culture, heritage education, and construction are important issues for Macao. With the development of digital technology in recent years, users can quickly search historical sites and save two-dimensional and three-dimensional images and videos through smartphones. These methods also enhance the communication power of culture. Virtual browsing on a smartphone requires computing power and storage space; yet, virtual reality devices are not widely used. Therefore, augmented reality and virtual reality are rarely used simultaneously for three-dimensional interactive guided tours and operation experiences on the same theme. However, by quickly creating virtual reality scenarios and preserving historical sites on mobile devices, 4DAGE’s 4DKanKan technology can provide augmented reality and metaverse virtual reality experiences. 4DKanKan can also integrate mobile guides and navigation software to connect mobile devices and assist in cultural inheritance and conduct sustainable education. This research linked this technology to the web by incorporating augmented reality and virtual reality technology to make designs and discussed the influences among service design, behavioral intentions, and learning effects. We collated and analyzed relevant data and text materials through systematic testing, observation, operation processes, and semi-structured interviews. The PLS multigroup structural model was used to explore and analyze the degree of influence and explanatory power of system quality, information quality, behavioral intention, and learning effects among themselves. The results of this study show that most users accepted the proposed innovative mode of operation and found it to be interesting and fun. Augmented reality is not limited by space or time; however, virtual reality devices taking too long to operate, switching too frequently, and having too many functional interfaces can cause operational problems. This study identified and modified the influencing factors and problems of the proposed system, with the aim of continuing to expand the applications of 4DKanKan to other cultural attractions or museums in the future. In addition, the research results can provide a reference for the sustainable development of related cultural sites.

The Feast of Drunken Dragon is a special intangible cultural heritage of Macau, which is also known as the Drunken Dragon and Lion Dance Gala. Every year, on the eighth day of the fourth month of the lunar calendar, members of the Macau Fish Traders Association hold a drunken dragon and lion dance activity at the Macau Sanjie Guild Hall. Festivals play a part in cultural designing. They not only attract a large number of tourists but also promote local culture. The Drunken Dragon Dance is currently encountering many problems such as the inability to introduce new performance methods as technicians are getting older, and young people are unwilling to inherit it. This cultural heritage tends to gradually decline. The Cultural Affairs Bureau of the Macao Government has paid attention to the problem. However, the publicity methods are still mainly based on videos, simple online graphics, and cultural and creative products, and the impact of the COVID-19 epidemic harmed the promotion. With the rapid development of technology, mobile devices provide digital reading and augmented reality (AR) to assist learning. Thus, learning is not limited in space and time, and individuals continue to use it without hindrance. Using the concept of experiential learning, we design interactive teaching materials with dynamic images to advertise the historical stories of the Feast of Drunken Dragon in Macau, folk rituals, and traditional dragon performances through the AR interactive experience of the drunken dragon festival. The concept of learning by doing is an experiential way to understand relevant intangible cultural heritage knowledge. Using digital content, teaching material design is provided based on user experience to achieve sustainable education.

Food waste is a global issue, and Macau is no exception. Throughout this study, it was found that most local bakeries in Macau employed promotional strategies to reduce surplus bread waste; however, a significant amount of unsold bread was still discarded. Meanwhile, as consumer behavior shifts toward environmental consciousness, technologies such as augmented reality (AR) are reshaping market dynamics. Many apps now incorporate the Sustainable Development Goals (SDGs) to raise consumer awareness. Within this context, this study recorded unsold bread types in real-time for four bakeries in Macau and integrated this information into an app system featuring interactive AR scanning technology to engage users and facilitate operations. Applying the Technology Acceptance Model (TAM), this study surveyed 163 local participants in Macau. Users expressed interest in immersive AR experiences that incorporated entertainment elements, allowing them to quickly search for and purchase surplus bread products, thereby reducing bread waste. However, excessive entertainment features were found to distract users from their purchasing goals, causing operational difficulties. Therefore, integrating AR into a well-structured shopping information system with streamlined operations would be more effective than adding excessive entertainment features. Future enhancements could include the addition of a comment section to facilitate discussion of the role of various virtual interactive systems in explaining surplus food concepts through experience. Emphasis should be placed on integrating sustainable practices into emerging technologies to increase users’ environmental awareness and achieve the Sustainable Development Goals.

Cantonese morning tea drinking is a cherished intangible cultural heritage in the Guangdong–Hong Kong–Macao Greater Bay Area in China and embodies Guangdong’s culinary tradition. In the digital era, innovative design techniques and digital technology have been applied to preserve and promote this tradition. To enhance heritage education, we designed an augmented reality device for Cantonese morning tea using Pepper’s Ghost technique. Employing field investigations, literature research, and experiments, we showcased Cantonese morning tea drinking. For further developments, affordable materials and professional photos are essential for constructing the model.
