Virtual Reality Versus Augmented Reality

Hello guys!
From the title above, its sure that we will get a little information about Virtual Reality and Augmented Reality!
Ok then, What is Virtual Reality?

Virtual Reality is a term where making a computer simulating a physical image like an reality. The more reality, more good that virtual reality.
So, for what is the purpose of Virtual Reality?
Virtual Reality occasionally used on Military Simulated, or Pilot Simulated. Where they begin studying how to ride an airplane or military jet. After that, they can try it in the reality soon.
Virtual reality can serve to new product design, helping as an ancillary tool for engineering in manufacturing processes, new product prototypes, and simulation. Among other examples, Electronic Design Automation, CAD, Finite Element Analysis, and Computer Aided Manufacturing are widely utilized programs.

The use of Stereolithography and 3D printing shows how computer graphic modeling can be applied to create physical parts of real objects used in naval, aerospace, and automotive industries,which can be seen, for example, in the VR laboratory of VW in Mladá Boleslav. Beyond modeling assembly parts, 3D computer graphics techniques are currently used in the research and development of medical devices fortherapies,treatments, patient monitoring,and early diagnoses of complex diseases.
Now about Augmented Reality,

Augmented Reality is a term where making the real world simulating a physical image using a device such as computer-generated sensory.
So, for what is the purpose of Augmented Reality?

Augmented Reality occasionally used on mobile applications where its using for GPS, sensors and many more. Modern mobile augmented reality systems use one or more of the following tracking technologies: digital cameras and/or other optical sensors, accelerometers, GPS, gyroscopes, solid state compasses, RFID and wireless sensors.
