XR Mall

XR MALL is a free multifunctional interpreting and public speaking learning app which combines virtual reality (VR), augmented reality (AR) and mobile technologies to allow learners around the world to study anytime and anywhere. XR MALL is designed for a research project based on a theoretical framework that integrates a constructivist approach, an interpreter competence model and a public speaking competence model.
The content comprises comprehensive learning resources, video lectures, VR practice, AR vocabulary lists, a feedback platform, a speech analysis tool, self-assessment materials, exercises, and guidelines for interactive dual-role-play interpreting activities. Users can choose the learning content (English-Chinese and Chinese-English interpreting or public speaking) and difficulty level (elementary or advanced) they wish to practice with.
For the interpreting practice, users can select (i) the mode of interpreting (e.g., sight translation or consecutive interpreting), (ii) the language direction (English-Chinese or Chinese-English), and (iii) the mode of practice (VR or non-VR). Users’ interpretations will be audio-recorded. Users are able to download their own recordings as well as model interpretations (source texts and translated texts) so that they can evaluate their performance based on the online self-assessment guidelines as well as comments on the feedback platform.
For public speaking practice, users can choose the speaking contexts (school or workplace). Users can add their own presentation slides into the app and practice delivering a presentation in VR using these slides.
Through the app, any independent user can learn by doing and immerse themselves in virtual learning environments that provide skill-based and profession-oriented practice with real-world features. Furthermore, it encourages collaborative learning in which learners can interact with each other online.
In addition to self-directed learning, XR MALL can be incorporated into traditional classes. In terms of pedagogical contributions, the app will potentially enable multi-sensory experience, promote learning motivation, and enhance teaching and learning effectiveness via practice on authentic and student-centered tasks.
