designing material for esp-xr: an augmented reality-based mobile application for english for specific purposes learning

This study presents the design and linguistic development of esp-xr, an augmented reality (ar)-based mobile application aimed at supporting the acquisition of domain-specific language in business, medical, and legal english. grounded in mobile-assisted language learning (mall), the project integrates a situational syllabus with a task-based approach (tba) to foster authentic communication and learner engagement. the business english module is outlined in detail, including the process of defining learning objectives and designing a syllabus tailored for a b2-level audience. drawing on corpus-informed methods, authentic materials were adapted to create interactive dialogues and ar-based vocabulary tasks aiming to enhance vocabulary retention through embodiment and gamification. while challenges were encountered—particularly in identifying concrete ar-representable items and maintaining textual authenticity—this study outlines the potential of ar-enhanced tools to promote immersive esp learning.
