The second key problem that AR technologies solves is the limited exhibition space. AR allows you to place an unlimited number of objects in an area equal to or less than that required to accommodate a single real-life object. You need to understand that an object in augmented reality is not necessarily a static 3D model. You can interact with it like a real one - reproduce mechanical actions (open doors, start processes and etc.). Moreover, you can overlay additional information on top of the virtual object, such as specification, video, explanations and other.
