Introduction

Augmented Reality is the perfect technology to add digital inputs over real-world ones. Try and picture operating smart glasses that display virtual objects or instructions directly in your field of view. Digital Physically Mixed World, This union of the virtual and real worlds creates a more interactive and engaging learning.

Training is important in manufacturing because it ensures that employees understand how to operate machinery, comply with safety requirements and deliver high-quality products. The reason why traditional training methods such as manuals and videos do not work great is because they are boring or hard to understand. AR changes this by turning learning into a physical and immersive process rather than just receipts that workers can learn faster, while also having better recall.

Benefits of Augmented Reality in Manufacturing Training
