Augmented reality (AR) combines the real world with virtual elements. A basic example is QR codes, which allow digital content to be accessed when a mobile device scans the code. AR can enhance learning and on-the-job training by providing interactive 3D animations or information that is accessed in real-time through triggers like photos or objects. While AR shows potential for education, it also faces challenges in working across different devices and reliance on learners having suitable AR-enabled technology.
