Handheld mobile AR described in the previous topic is mostly about augmenting 2D video with regard to the phone camera's location in 3D space. Optical wearable AR devices are completely about 3D data. Yes, like mobile AR, wearable AR devices can do target-based tracking using its built-in camera. But wait, there's more, much more!
These devices include depth sensors that scan your environment and construct a spatial map (3D mesh) of your environment. With this, you can register objects to specific surfaces without the need for special markers or a database of target images for tracking.
A depth sensor measures the distance of solid surfaces from you, using an infrared (IR) camera and projector. It projects IR dots into ...
