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’. This could, of course, mean anything but it usually refers to a specific type of reality emulation. Also, virtual reality is the term used to describe a three-dimensional, computer generated environment which a person can explore and interact with. That person becomes part of this virtual world or is immersed within this environment and whilst there, a series of actions can be manipulated objects or performed.
Using 360° stereoscopic spherical video and 360 x 360 surround sound from professional VR video cameras can capture virtual reality environment. The virtual reality environment can be emerged in by the users using head-mounted displays.
In the 2010s, now some advanced haptic systems include tactile information, generally known as force feedback in applications of medical, video gaming and military training. Some VR systems used in video games can transmit vibrations and other sensations to the user through the game controller. Also, virtual reality applies to remote

This is where means of a robotic device perform surgery– controlled by a human surgeon, which time and risk of complications are reduced. Virtual reality has been also being used for training purposes and, in the field of remote tele surgery in which the surgeon perform a surgery at a separate location to the patient. The main feature of this system is force feedback as the surgeon needs to be able to measure the amount of pressure to use when a delicate procedure is performed. However, there is an issue of time delay or latency which is a serious concern as any delay – can feel abnormal to the surgeon and interrupt the procedure. So there needs to be precise force feedback to prevent
Abstract - Over the past 100 years modern science has been responsible for some miraculous inventions to aid the delivery of medical treatment such as the x-ray machine, ultra sound technology and the cochlear implant. One of the latest improvements is in the field of robotic surgery, which is redefining the way in which patients undergo procedures. Not to be confused with computer-aided surgery, robotic surgery utilizes the robot to actually perform the manual tasks of the surgery. In fact, there is no second thought that robotic arm performs the surgery under the assistance of a doctor. In this research paper we have explored the working of robotics arm, the benefits of conducting patients operations via robotic arm, the problems faced in
In the past the field of view was not that much and a user could not look more than 170 to 210 degree. But now the companies have focused on making the VR gears to be for a whole 360 degree experience. Star Wars game is also one of the best example in this regard as it makes you feel like you are the soldier who is in the game and you are in that battlefield.
Virtual reality gives a computer-generated simulation of a three-dimensional picture or environment that encompasses a client and can be associated with in an apparently real or physical way by an individual utilizing uncommon electronic equipment, for example, a helmet with a screen inside or gloves fitted with sensors. It has the capacity react, typically through immersive head-mounted displays (HMDs) and head tracking. Gloves giving hand tracking and haptic/touch-delicate feedback may be utilized too. Room-based frameworks give a three dimensional experience to various users; nonetheless, they are more constrained in communication abilities. A standout amongst the most popular virtual reality gadgets is the Oculus Rift.
Robotic Surgery is an emerging technology that utilizes purpose-built robots to perform surgical procedures on patients. At present these robots are not autonomous, they are controlled by a surgeon at all times.
The simulated reality hypothesis is a simple idea that says that we, and everything in the known universe, is currently living inside a computer simulation. This idea has been talked about by philosophers for centuries and even has some ties to religion. Sci-fi writers have been writing about simulated reality for years and we have seen it visualised on tv shows yet the idea that we may be living inside of a computer simulation is almost unknown to most people.
Virtual reality can be used as an educational tool to assist not only students but teachers as well. Another major benefit of virtual reality is its use in the healthcare field. It can be used to treat several medical conditions such as anxiety disorders, mental health issues such as phobias, and it can even be used as a pain reliever (Matheison, 2017).
So now that we have gone through the history, let’s talk about what’s been going on with virtual reality today. What’s it currently being used for. Well like in the past it is still mostly used for entertainment and training purposes. For example when it comes to entertainment we already talked about “Google cardboard”. With the Google cardboard you can kind of go on a virtual tour of different places around the world. Another example of entertainment would be Sony’s Playstation VR which we also talked about earlier.
VR is extremely useful for training solders in order to prepare for combat missions or other potentially dangerous scenarios as this can help them learn how to behave when on the battlefield. VR enables them to do so without immersing themselves into a real life situation before they are fully ready, this removes any risk of injury of fatalities. For example
The term Virtual Reality (VR) is used by many different people with many meanings. There are some people to whom VR is a specific collection of technologies, that is a Head Mounted Display, Glove Input Device and Audio. Some other people stretch the term to include conventional books, movies or pure fantasy and imagination. However, for purposes of this research, we restrict VR to computer mediated systems. We would define Virtual Reality as a way for humans to visualize, manipulate and interact with computers and extremely complex data.
Design and implement a few haptic related projects for the benefit of physically challenged people. This proposal develops an approach for haptic exploration of unknown objects by robotic fingers. Because haptic exploration is coupled with manipulation and exploration using a sequence of phases is presented. With specialized fingers and sensors and appropriate planning and control robots can also be enabled to explore the worlds through touch. Haptic exploration has applications in many areas including planetary exploration, undersea salvage, operations in remote and hazardous conditions. Application of the human haptic interaction, multi sensory perception, action and multimodal feedback can be applied in the fields of education, rehabilitation, medicine, computer aided design, skill training, computer games, driver controls, simulation and visualization.

Virtual reality gives huge benefits in education and helps to improve student engagement. It’s one of the best ways to engage and helps the students to understand the subject through virtual reality system. Especially in the virtual reality game will bring significant impact to teenagers. The major three types of impact are social difficulty (socially impaired), physical and psychological difficulty. Even virtual reality is a great tool to learn, but it is not a universal learning method for all of the educational areas. Too much of virtual reality for students will cause social difficulties because an inescapable aspect of social life is the formation and maintenance of interpersonal relationships (Biocca and Levy 1995). Constantly using virtual reality will cause isolation from the societies because the person already made his or her own social area which only exists in the virtual world. VR will provide a communication environment in which the dangers of deception and the benefits of creativity are amplified beyond the levels that humans currently experience in their interpersonal interactions (Biocca and Levy 1995). It could lead to low self-esteem, feelings of worthlessness and insignificance, even self-destructive acts (Cartwright, 1994). VR games could mindlessly, energy sapping diversion, bring electronic isolation, a playground for immortality (Kershner 1995). Virtual Reality game brings physical and psychological difficulties when they over run and it could be called as cyber sickness. VR interventions were able to increase physical activity capacity and performance in children with CP (Cerebral palsy) or early brain injury. Cyber sickness is one of the physiological impacts durin...
In order to effectively create a 3-D environment for the user, virtual reality combines the elements of immersion and interactivity. Immersion is the user's contact with the virtual reality with as many senses as possible including; sight, hearing, and touch.
Virtual Reality allows designers and developers to create an experience that is not real, but gives the effects and the experience as being real, hence, a virtual reality! There are many ways in which this can be used such as for games, simulations, training, experiencing a distant location from the comfort of your home and so much more.
