Virtual Reality
The definition of virtual reality comes, naturally, from the definitions for both ‘virtual’ and ‘reality’.
The definition of ‘Virtual’ is near and reality is what we experience as human beings. So the term ‘virtual reality’ basically means ‘near-reality’.
We know the world through our senses and perception systems. In school we all learned that we have five senses: taste, touch, smell, sight and hearing. These are however only our most obvious sense organs. The truth is that humans have many more senses than this, such as a sense of balance for example.
Virtual reality is an artificial environment that is created with software and presented to the user in such a way that the user suspends belief and accepts it as a real environment. On a computer, virtual reality is primarily experienced through two of the five senses: sight and sound.
Virtual reality (VR) will ultimately impact everything from real estate to retail and healthcare and education. Business meetings, conferences and concerts will soon all be held in virtual environments.
Applications of Virtual Reality
Business
Virtual reality is being used in a number of ways by the business community which include
• Virtual tours of a business environment
• Training of new employees
• A 360 view of a product Training
Training
• Virtual reality environments have been used for training simulators
• Examples include flight simulators, battlefield simulators for soldiers, paratroopingEngineering and Design
Engineering and Design
• VR is widely used in engineering and designing process
• It gives better understanding of the design and facilitates changes wherever necessary
• It helps to reduce the time and cost factor Examples: Building construction, car designing
Medical
• Healthcare is one of the biggest adopters of virtual reality which encompasses surgery simulation,
phobia treatment, robotic surgery and skills training
• VR finds its application in nursing, dentistry, health issues for the disabled
Entertainment
• The entertainment industry is one of the most enthusiastic advocates of virtual reality, most noticeably in
games and virtual worlds
• Virtual Museum e.g. Interactive Exhibitions
• Virtual theme parks

Mixed Reality
Mixed reality (MR) sometimes referred to as Merged reality is the merging of real and virtual worlds to produce new environments and visualisations where physical and digital objects co-exist and interact in real time.
Users gain a real-time view of actual surroundings combined with an overlay of intelligent virtual objects that allows for new interactions through gesture and voice based inputs.
Mixed reality augments the real world with virtual objects that aim to look as if they are really placed within that world. It locks their position according to real world objects (e.g. placing a virtual cat onto a real world table and having it remain there in augmented reality while the user walks around their house). Microsoft’s HoloLens, Magic Leap and the Meta 2 are all working towards this style of augmented reality, where virtual things do indeed look as if they are part of your real world.
To experience Mixed reality you need a headset that can also do simpler augmented reality things too like showing notifications and simple data in a way that is locked to your display, rather than the world. It is the bringing of virtual objects in a more realistic way into the user’s view that gets it into mixed reality territory.

Also Augmented Reality is technology that combines virtual reality with the real world. The current world of augmented reality deals with live video imagery which is digitally enhanced with computer generated graphics.
Augmented reality apps are written in special 3D programs that allow the developer to tie animation or contextual digital information in the computer program to an augmented reality “marker” in the real world. When a computing device’s AR app or browser plug-in receives digital information from a known marker, it begins to execute the marker’s code and layer the correct image or images.
Conclusion
Virtual reality replaces your world with a virtual one. Augmented reality supplements your world with digital objects of any sort. Mixed reality seamlessly integrates digital objects into your world making it look as if they are really there.
