The technology central to augmented reality applications includes computer vision, depth tracking, and motion sensing. These technologies enable devices to identify physical environments and overlay digital content seamlessly. For instance, using cameras and sensors, augmented reality extracts spatial information from the user’s surroundings. Additionally, smartphones and smart glasses provide the hardware necessary for displaying augmented information. By combining real-world environments with virtual elements, augmented reality enhances user interaction and can be applied in various fields, such as gaming, education, and retail.
