Extended Reality (XR) in Teaching and Learning
Extended Reality in Higher Education
Extended reality (XR) technology refers to a spectrum of immersive technologies that blend the physical and virtual worlds. There are three main types of XR:
Virtual reality (VR): creates a fully immersive, computer-generated environment that users can interact with using specialized hardware, such as head-mounted displays or handheld controllers.
Augmented reality(AR): overlays digital information onto the real world, typically viewed through a smartphone or tablet.
Mixed reality(MR): combines virtual and real-world elements in real-time, allowing users to interact with virtual objects while still seeing the physical environment around them.
VR museums
A VR (virtual reality) museum is a digital representation of a physical museum that allows visitors to explore exhibits, collections, and galleries in a virtual environment using VR technology. In a VR museum, visitors can interact with exhibits in a way that is not possible in a physical museum, such as zooming in on artifacts or examining them from different angles.
VR museums can be used to support the preservation of both tangible and intangible cultural heritage.
- VR museums can help to reach a wider audience, including those who may not be able to physically visit a museum. This can help to raise awareness about both tangible and intangible cultural heritage and the importance of their preservation.
- VR museums can be used to create digital archives of cultural heritage, which can be used for research, education, and future preservation efforts. These archives can include both tangible and intangible heritage elements and can be shared with museums and cultural institutions around the world, promoting collaboration and the sharing of knowledge and resources.
The VR Museum of Hungry Ghost Festival
This is the first virtual intangible cultural heritage museum in Hong Kong. Its aim is to promote public education, and enhance people's understanding and sense of identity with Chinese culture and the Hong Kong community.
- In addition to historical pictures, newspaper reports, and comics belonging to intangible cultural heritage, the museum showcases 3D models of the Yue Lan Festival created by the Professor Selina CHAN’s research team and the Teaching and Learning Development Office using photogrammetry, as well as a high-resolution 8K 360-degree panoramic view of the Yue Lan Festival space (VR 360).
- Audiences from anywhere in the world can enter the museum using VR headsets or Oculus, or they can download a free software to enter the museum using their home computer. At any given time, the number of visitors in the museum is limited to 30 people. The public can browse the exhibition boards in the museum, travel through time and space to experience the sounds, colours, arts, and people of the actual community during the Yue Lan Festival in 2021. They can even interact and discuss with other museum visitors, deepen their understanding of local culture, and learn about the inheritance and innovation of intangible cultural heritage, which helps to promote and conserve national intangible cultural heritage.
The VR museum of Ving Tsing
The Teaching and Learning Development Office has collaborated with the Department of Journalism and Communication and the Ving Tsun Athletic Association to design the first virtual reality Ving Tsun Museum. The museum showcases precious documents related to the development of Ving Tsun in Hong Kong. Visitors only need to wear equipment to "travel through time and space" to the address of the Ving Tsun Athletic Association in Mong Kok, and practice martial arts in the metaverse. Visitors can also design their own virtual avatars and interact with other attendees.
Chinese medicine AR card games
The Teaching and Learning Development Office worked with the General Education Office to develop a mobile app and augmented reality (AR) games to promote traditional Chinese medicine (TCM) education. The primary goal is to publicize TCM, which is an integral part of Chinese culture, and to spark interest in this subject via interactive AR games.
The project team has created 3D models of different Chinese medicines, which users can preview by scanning physical cards with the AR function. The interactive AR card game includes "Symptom Cards" and "TCM Cards". Players scan both cards, and the matching result appears on the screen with an explanation and nature of the Chinese medicine. By using AR technology to provide an immersive and interactive experience, this project hopes to attract a wider audience to learn about TCM and its benefits.

Cognitive disorders AR simulators
This is an AR mobile app designed to help students understand mental and perception disorders. The app simulates the perception of a patient with different disorders in a real-world environment. By altering users’ perception of reality using virtual objects and the phone's camera and microphone, users can experience different the symptoms of different disorders such as hallucinations and motion blindness. The primary goal of this app is to provide students with a more immersive learning experience that enables them to better understand and empathize with patients who suffer from these disorders.
Social Work Virtual Fieldtrip to Adult Training Centres
3D models were created to show the daycare and residential areas of adult training centres. These models offer a unique opportunity for students to embark on virtual field trips, immersing themselves in an interactive and engaging experience that deepens their understanding of the daycare centre’s environment and the diverse functions of its facilities. To enhance the educational value, the models have been enriched with close-up photos of specific equipment and mini demonstration videos, presenting comprehensive insights into the operational aspects and functionality of the adult training centre.
