The Augmented Reality is the superposition of reality and elements calculated by a real-time computer system. It often refers to the different methods of realistically embedding virtual objects in a sequence of images.
Mixed reality is a variation of AR ; it features the fusion of real and virtual worlds to produce new environments and visualizations, where physical/living and digital objects coexist and interact in real time.
OST-AR (optical see-through augmented reality) => The screens are transparent so that the real world is visible through the optics and the digital content added.
Commonly used equipment: Augmented Reality or Mixed Reality Glasses
VST-AR (video see-through augmented reality) => Use of content from the camera filming the real world and integrated in a virtual reality environment.
Commonly used equipment: smartphones, tablets
