How Do AR Smart Glasses Work

AR smart glasses are worn over the eyes like normal eyeglasses but unlike normal eyeglasses, work by generating and/or overlaying computer-generated or digital graphics, images, videos, animations, and three-dimensional holograms over the real-world scenes or environments seen by the user at their points of view to enhance the user’s vision.

Unlike VR, augmented reality smart glasses do not replace the user’s environments or scenes with completely virtual ones but instead add 3D images on top of real-world environments to augment the user’s view.

It may use a camera, sensors, or other environment or object identification technologies to identify a pre-loaded marker (image of the marker is pre-loaded on the app and so the camera searches for similar images in the user’s real-world scene) on which to overlay the pre-defined digital 3D images. These glasses may also use geolocation methods such as GPS or SLAM (algorithm-based simultaneous localization and mapping technology that also gets data from sensors) or two or all of the three combined to determine the user’s location and hence determine which user’s environments to overlay with digital 3D images or holograms.
