Let's discuss technology with @Blogging-Mech

Along with the rapid technological advances make people more creative in creating something. This time @Blogging-Mech will discuss one of the great technology that is Virtual Reality.

Virtual Reality is a technology that can make users Interact with the environment in the virtual world that is simulated by the computer and make it as if its users are in the environment that is actually a clone or really a place that only exists in the imagination. This technology is able to make people who feel it is fooled and convinced that what happened is real.

Some Tools that can make us feel the sensation of Virtual Reality :

A headset is a useful tool for monitoring head movement. In addition, this device that provides an environmental view to the user so as if the user to see the real world.

A glove is an input device that can capture hand movements and send motion information to a virtual reality system.

Walker is a device intended to monitor foot movements. This equipment can be used to set the wearer's feet to feel the burden as if stepped in the real world. For example, the feet will feel heavy to move when the user is facing that swamp or muddy terrain.

Virtual reality allows users to view dynamic images that are the result of computer simulations. With a special tool device of  Virtual Reality, the user can interact with that world and get feedback as if real both physically and psychologically, so that the user feels like he is in a real situation.

The work system of virtual reality cannot be separated from some important elements,

1. Virtual Word

 A virtual world is a three-dimensional environment that is often, but not necessarily, realized through a medium (i.e. rendering, display, etc.) where one can interact with others and create objects as part of that interaction. In a virtual world, visual perspectives are responsive to changes in movement and interactions mimic those experienced in the real world. 

2. Immersion

Virtual reality immersion is the perception of being physically present in a non-physical world. It encompasses the sense of presence, which is the point where the human brain believes that is somewhere it is really not, and is accomplished through purely mental and/or physical means. The state of total immersion exists when enough senses are activated to create the perception of being present in a non-physical world. Two common types of immersion include:

Mental Immersion - A deep mental state of engagement, with suspension of disbelief that one is in a virtual environment.

Physical Immersion - Exhibited physical engagement in a virtual environment, with suspension of disbelief that one is in a virtual environment.

3. Sensory feedback

 Virtual reality requires as many of our senses as possible to be simulated. These senses include vision (visual), hearing (aural), touch (haptic), and more. Properly stimulating these sense requires sensory feedback, which is achieved through integrated hardware and software (also known as inputs). Examples of this hardware and inputs are discussed below as key components to a virtuaL reality system, which include head mounted displays (HMD), special gloves or hand accessories, and hand controls.  

4. Interactivity

 The element of interaction is crucial for virtual reality experiences to provide users with enough comfort to naturally engage with the virtual environment. If the virtual environment responds to a user’s action in a natural manner, excitement and senses of immersion will remain. If the virtual environment cannot respond quick enough, the human brain will quickly notice and the sense of immersion will diminish. Virtual environment responses to interaction can include the way a participant moves around or changes in their viewpoint; generally through movements of their head.

With the development of VR technology, now that technology has been supporting human life in many ways such as health, military, transportation, economy, media, and entertainment.
